In every respect, the Vauxhall Astra VXR is a more extreme version of the GTC, and nothing embodies the visual changes more than the new models exterior design revisions.

Adding extra presence, the Vauxhall Astra VXR gets a specially sculpted front and rear bumper, side skirts, aerodynamic roof spoiler and twin bumper-integrated tailpipes. Standard 19-inch wheels with 245/40 ZR tyres underpin the dramatic body, with 20-inch forged items available as an option for those customers who want to make their cars look even bolder.

"The Astra VXRs appearance is muscular and masculine," said Brit, Andrew Dyson, the cars chief designer who works in Vice President of Design, Mark Adams team. "Just a quick glance at its exterior reveals that the car is fast and agile. It really looks like it was made for high performance driving, and for its driver to push the limits."

The VXR shares much of its design with the GTC. Only three lines are used to create tension and define the outline of the silhouette. A fine, crisp line sweeps downwards from the front door to the bottom of the rear wing; a second line strikes through the door handle and stretches to the rear, emphasising the cars dramatic stance and broad shoulders. A third line follows the roofs clean, rakish silhouette.

Customers who want to personalise their VXR still further can opt for the Aero Pack, which comprises side-skirts which extend still further, a body-coloured logo bar on the front grille, a two-tier rear spoiler and 20-inch forged alloy wheels.

Exterior colours include: Arden Blue, Carbon Black, Power Red and Summit White.
Interior
The centre-piece of the Vauxhall Astra VXRs cabin is Vauxhalls all-new flat bottom steering wheel. Its diameter has been reduced from 370mm to 360mm compared with all other models in the Astra range, making the steering feel even more precise and direct. The handwheels grip has been enhanced by packing supple sponge rubber around a magnesium/steel hybrid ring and then covering the entire wheel in premium, soft cross-stitched leather. The wheel is available with an optional heated rim, and features the VXR logo, as well as multi-function controls on its spokes.

Other VXR-specific features abound, including a unique sports gearlever and alloy-plated pedals with rubber studs for better foot grip. Glossy piano-black chronograph-inspired dial rings contrast against a satin-black background, while the wing-shaped upper instrument cluster flows back into the doors and armrests. Black headlining, VXR-branded floor mats, and door panel stitching in Arden Blue or Cool Pearl give the Vauxhall Astra VXRs interior a purposeful yet exclusive feel.

A new design of front sports seat, made with cutting-edge lightweight material is standard across the Vauxhall Astra VXR range. Mounted 17mm lower than in the Astra GTC (and 30mm lower than in an Astra Hatch) the seats give front occupants a heightened sense of connection with the cars chassis.

Made from a strong but agile polyamide/fibreglass composite, the seat shells are formed using an organic injection-molded sheet which due to its strength only needs to be 2mm thick, and contributes to a 45 per cent weight saving compared with a seat using a conventional shell.

As standard, all Astra VXRs get manually adjustable front seats trimmed in half Black Track cloth and half Morrocana fabric. However, two option packs are also available. The VXR Performance Seat Pack (£495) adds full electric adjustment, heated seats, a manually extendable front seat cushion and lumbar/side-bolster adjustment as part of a package that includes a total of 18 different seat settings.

In addition, a Full Leather Pack (£1150) is available, comprising the multi-adjustable electric seat with a high-quality leather finish, embossed with the VXR logo. Two versions of the leather seats are available, each of which has a vertical leather stripe in the centre, picked out in either Arden Blue stitching or a gloss leather with Cool Pearl stitching (with matching door panel stitching). The VXR logo is embossed into the upper part of the front seats, while the seat itself is perforated to provide an air circulation function.

CHASSIS
While the Vauxhall Astra VXR is based on the new GTC, it has benefitted from a raft of bespoke chassis modifications to cater for the significant boost in performance brought by the 2.0-litre turbocharged engine, which produces 280PS and 400Nm of torque.

With its dynamics developed by Vauxhalls engineering team, led by ex-DTM star Volker Strycek, the Vauxhall Astra VXR will target the very best rivals in class for handling, grip and overall driving excitement.

Setting it apart from all other current Astras is a specially developed mechanical limited slip differential, which works on the front wheels. In conjunction with the GTCs sophisticated HiPerStrut (High Performance Strut), the LSD provides the Vauxhall Astra VXR with exceptional lateral grip and traction through the bends.

Further changes to the chassis include brakes developed by competition supplier, Brembo, standard fitment of Vauxhalls fully adaptive FlexRide damping system, uprated springs and new dampers developed between VXR and ZF Sachs.

Mechanical Limited Slip Differential developed with motorsport supplier
Drexler, who supply differentials to the motorsport industry, have worked with Vauxhall to develop a mechanical multi-plate limited slip differential for the Vauxhall Astra VXR.

The unit, derived from that used in the Corsa VXR Nürburgring Edition, creates a locking effect with a ramp angle of 45 degrees under acceleration and 90 degrees under deceleration. The locking effect improves traction when its needed - such as under acceleration through bends or over changing cambers and surfaces - but the effect is relaxed off-throttle, when its not required, making the steering more benign.

To cater for the improved traction brought by the LSD, the Vauxhall Astra VXRs Traction Control (TC) and Electronic Stability Control (ESP) systems have been re-tuned to ensure the best performance, even when the car is used on track or in wet conditions.

VXR and Brembo develop bespoke braking system

With cross-drilled and ventilated 355 x 32mm front discs, four-piston callipers and harder compound brake pads, Vauxhall and Brembo have co-developed a bespoke braking system to cater for the Vauxhall Astra VXRs 280PS performance.

Using floating discs, the brakes are made from two different materials, with a cast-iron rotor mounted on an aluminium disc bell. This helps combine the heat resistance from cast iron with the light-weight properties of aluminium.

The key advantages of the system are reduced heat build up during repeated braking, as well as an improvement in overall brake feel through the pedal. There has also been a significant weight saving compared with the system found in the GTC, with each front calliper weighing 5.1kgs (-2.8kgs) and each front disc weighing 4.2kgs less than on the standard coupe. This means a total reduction of 7kgs per front corner from the cars unsprung weight.

The brakes, as well as all other chassis elements, were tested on public roads and in the toughest of environments including the Nürburgring and Contidrom race tracks in Germany, as well as on ice and snow in Scandanavia, and in the searing Spanish heat at the Idiada test track.

Springs, dampers, roll bars and bushes all improved for greater performance

Compared with the 1.6-litre, turbocharged GTC model, the Vauxhall Astra VXRs springs have been stiffened by 30 per cent and the car lowered by 10mm at the front and rear, to allow more driver connection on road and track.

The Astras clever compound crank/Watts link rear suspension was also stiffened, as were suspension bushes all round to cope with the extra chassis loads. The front anti-roll bars diameter increased by 5mm over the GTCs, again for added stiffness.

Working with motorsport manufacturer, ZF Sachs, Vauxhall developed bespoke damper settings for the Vauxhall Astra VXR, using larger diameter pistons to the GTCs. The suspension sub-frame also rests on special mounts, the elastic-kinematic nature of which improves steering agility and support even when subjected to extreme lateral forces through tight bends.

HiPerStruts improve steering feel and help reduce torque-steer

The Vauxhall Astra VXR is equipped with a version of Vauxhalls HiPerStrut, also found on all GTCs and the 325PS Insignia VXR.

By reducing camber change during cornering, the HiPerStruts improve grip, reduce torque-steer significantly and enhance steering precision, due to a shorter and more compact rotational axis. Each strut has a 44 per cent reduced kingpin inclination and a spindle length (or kingpin offset) reduced by 46 per cent. This in turn means less camber loss during cornering, and therefore more grip, while the shorter spindle quells torque-steer reactions.
Standard FlexRide provides drivers with ultimate control

Vauxhalls FlexRide adaptive damping system is standard on all Astra VXRs. Drivers have the choice of three separate chassis settings which can be selected at the push of a button. Standard delivers all-round performance for a wide range of road driving, with Sport stiffening the dampers for reduced roll and tighter body control.

VXR is FlexRides most extreme mode. Not only does it enhance throttle responsiveness, and change the instrument backlighting from white to red, but it alters the dampers settings once again. A ramp-control sub-mode further stiffens the dampers, but ensures that the wheels are in contact with the road instantly after hitting a bump. This means the car has a soft landing even when the springs on the struts rebound on an uneven surface. Meanwhile, the roll control sub-mode reduces tilt further during cornering.

Three modes of ESP to suit road and track driving
The Vauxhall Astra VXRs ESP (stability control) system offers three different modes. In its default mode, optimum safety is prioritised for everyday road conditions. Competitive mode raises the threshold at which the automatic systems intervene, though when it senses a dangerous situation it will stabilise the car via the braking system. Finally, in ESP-off mode, activated by pressing the button down for five seconds, the ESP system can be completely deactivated.

Two choices of unique wheel designs
As standard, the Vauxhall Astra VXR is equipped with flow-formed 19-inch alloy wheels with Pirelli 245/40 ZR tyres front and rear. However, customers can also opt for state of the art forged alloy 20-inch wheels, which weigh just 1.86kgs - 14 per cent less than the 20-inch rims available on the GTC model. The forging process used to make the lightweight rim creates a tougher material, allowing less aluminium to be used in its construction, and therefore reducing weight.

Combined with the savings in weight brought about by the Brembo discs, opting for the 20-inch rims on the Vauxhall Astra VXR gives drivers a total unsprung weight saving of over 14.5kgs across the front axle.

POWERTRAIN
Vauxhalls new Astra VXR will incorporate deliver a class-leading 400Nm of torque, giving it a 0-60mph time of 5.9 seconds and robust mid-range performance.

The VXRs turbocharged, 2.0-litre direct-injection engine harks from the Insignia family, but while its aluminium block is similar, the VXR has a unique aluminium cylinder head and new turbocharger to liberate 280PS (up 40PS on the previous model) and over 200Nm per litre of torque - the highest specific output in its class.

Developing a high-torque engine for the Vauxhall Astra VXR was the key to unlocking the cars real-world, mid-range performance, rather than focusing on power alone. And with maximum torque produced on a broad plateau between 2450rpm and 5000rpm, VXR drivers will never want for instant acceleration.

An all-new, state-of-the-art intake system was developed to feed as much air into the turbocharger as possible. The turbocharger itself was also improved to take more charge-air pressure, which builds from as early as 1400rpm for linear and strong acceleration. The maximum charge pressure is now 1.5 bar - 25 per cent more than in the Insignia 2.0T.

Vauxhall Astra VXR drivers can also look forward to a soundtrack that has been carefully engineered to appeal to enthusiasts, both from inside and outside the car. Drivers will get the full effect in the mid-to high rev range, especially when they change up from third to fourth under full throttle.

But outright performance hasnt come at the expense of efficiency and durability. Like all recent VXR models, the Astra was subjected to prolonged testing at the Nüburgrings notorious Nordschleife for 10,000 kilometres under race conditions - the equivalent to around 110,000 road miles.

And while the Astra VXR can accelerate from 0-60mph in just 5.9 seconds and hit a maximum 155mph, standard Start/Stop technology has reduced fuel consumption by 14 per cent (compared with the previous model) to a combined 34.9mpg, and reduced emissions to 189g/km.

All-new engine air intake system
Vauxhall engineers developed a completely new air intake system to improve air flow dynamics, reduce pressure loss and boost the engine performance even further.

The size of the intake air duct was significantly increased, as was the air cleaners volume, reducing intake noise and allowing a greater quantity of air to be processed. This helped improve fuel consumption to a combined 34.9mpg, while reducing emissions to 189g/km - a 12 and 14 percent drop respectively compared with the previous Astra VXR.

Toughened and more durable turbocharger for quick throttle response

The engines turbocharger is based on the twin-scroll principle. This means that in the exhaust manifold and turbocharger, the channels of the first and fourth cylinders are separated from those on the second and third cylinders. The pulsating exhaust gases are fed through spirals (scrolls) and brought together directly ahead of the turbine. By separating the flows, their dynamics are fully exploited.

The build-up of pressure starts as early as around 1400rpm. The maximum charge pressure has been increased to 1.5 bar - that represents a 25 per cent increase compared with the one used in the 2.0T Insignia. It was therefore necessary to make the turbocharger even tougher, more durable and able to withstand the increase in pressure.

Further important features to this compact turbocharger include the pneumatic over-run air valve and an efficiency-optimised turbine wheel. At a defined vacuum, a valve is opened which leads the air back to the compressor inlet. This keeps the speed of the charger at a high level. When the accelerator pedal is pressed again, charge pressure is then immediately available. To increase volumetric efficiency in the combustion chambers, the pre-compressed air is cooled by around 100 degrees Celsius in an intercooler before entering the chambers.

Optimised exhaust system for even better performance
Engineers also focused on reducing exhaust back pressure as a way of improving engine performance. Both the closed-couple converter (the catalyst near the engine) and the under-floor converter were tuned to reduce exhaust back pressure. Along with increasing the bore of the entire exhaust system, Vauxhalls engineers achieved a 25 per cent overall reduction in exhaust back pressure, versus the system used in the Insignia 2.0T.

In line with the mechanical changes made to the intake, exhaust and turbocharger, elements of the engine control unit (ECU) governing charge air pressure, fuel injection rate and ignition were all re-tuned.

Sound engineering
For drivers of cars like the Vauxhall Astra VXR, the soundtrack when you accelerate is almost as important as the time it takes to reach 100mph. So needless to say, engineering the right type of engine noise was an important part of the cars development.

Using a recent amendment to European noise regulations on pass-by noise - also known as the Lex Ferrari rule - engineers were able to liberate 75 decibels for the Astra VXR, a full decibel louder than the Astra GTC 1.6T. In order to pass the Lex Ferrari test, the Vauxhall Astra VXR had to accelerate from 50kph to 61kph in third gear on a stretch of road measuring just 15 metres - normally a challenge for all but the most powerful cars.

With an underlying robustness in its character, the engine noise recreates the jet-like noise of its predecessor under mid to high revs, when heard from inside the cabin. And thanks to the removal of one of the GTCs three silencers, theres even a distinctive burble at idle.

The twin bumper-integrated tailpipes have parallelogram-shaped openings and are unique in this class.

Nordschleife - the ultimate proving ground!
Before the modified Astra VXR engine could go into production, it was subjected to a series of challenging tests, one of which was to circulate the Nordschleife segment of the Nürburgring at race speeds for 10,000 kilometers, roughly equal to 180,000 road miles.

To achieve this level of durability, the Vauxhall Astra VXRs engine incorporates some novel features. Its high thermal endurance is supported by a water jacket which extends to the bottom of the cylinders, as well as oil-spray cooling for the underside of the pistons. Both camshafts in the engine respond automatically to an electro-hydraulic cam phaser, matching the valve opening times to the engine load status via the engine control unit. In addition, a higher overlap at lower speeds with continuously variable camshaft phasing ensures the turbocharger responds more quickly. The outlet valves are sodium-filled and all valves are actuated via low friction roller valve levers.

Other engine features are two counter-rotating balance shafts, low-maintenance chain drive for the camshafts and a cast-on oil filter housing, which is easily accessible from above. An oil change simply requires replacing the cartridge and is signaled by an interval indicator. Sensors measure wear and tear of the fully synthetic lubricant according to parameters such as the number of cold starts, as well as the overall number of starts.

MARKET & RIVALS
Volker Strycek, head of VXR product development and a former DTM driver and Nürburgring 24-hour winner, makes it clear about what his team wanted to achieve with the all-new Astra VXR. "Our goal was quite simple: to be the best in segment."

And with the UKs hot-hatch market brimming with fresh and exciting products, the new Astra VXR had to raise the bar still further. Key to its success was the sophistication of its powertrain and chassis. With 280PS, the VXR produces more power than any of its current rivals, allowing it to accelerate from 0-60mph in a class-leading 5.9 seconds. But the killer punch is its 400Nm of maximum torque, giving it the highest specific output in its class.

The new VXRs chassis will be equally competitive, with a mechanical limited-slip differential (unique in class as a standard item), HiPerStrut front suspension, and bespoke brakes, springs and damper settings.

As with the previous Vauxhall Astra VXR and the current GTC, the UK will be the new models biggest market. Around 10 per cent of all GTC volume will be VXR, equalling about 1200 units per year - the highest of any VXR model.

Key rivals will come from Volkswagen and Renault in the form of the Scirocco R and Megane Sport 265 (as well as the Focus ST, when it arrives in the UK). But the Astra VXRs keen pricing - £26,995 on the road - will undercut the Sciroccos by nearly £4,000, and that of the Megane 265 by more than £2000 when the Renaults equipped with its optional Cup Pack, including 19-inch alloys and a limited-slip differential (both standard on the Vauxhall).

Other standard equipment on the Vauxhall Astra VXR includes FlexRide adaptive damping, DAB, USB, Bluetooth and LED tail lights.

Vauxhalls unique Lifetime Warranty will also provide first owners of the VXR with the reassurance of comprehensive cover for however long they own the car.

The UKs hot-hatch class has become significantly hotter in the seven years since Vauxhall launched the first Astra VXR. Back then, the class norm for power was between 200PS and 250PS (the first Astra VXR produced 240PS), whereas now it starts at around 230PS right up to the new VXRs 280PS.

VXR customers can choose from a wide range of optional extras, including full leather upholstery and electrically adjustable seats, satnav with SD card and aux-in and Intelligent Adaptive Forward Lighting. One of the most popular options will be the VXR Aero Pack, which Vauxhall expects 85 per cent of customers to choose. For just £995, it includes 20-inch alloy wheels, a BiPlane Rear Spoiler and extended side skirts.

VXR - one of the fastest growing automotive sub-brands
The VXR brand has gone from strength to strength since the first car - a VXR220 Turbo - went down the line in 2004.

Buoyed by the success of Vauxhalls BTCC programme, the VXR badge was soon applied to a wide range of models, from the V8-powered Monaros to the Corsa, Vectra, Zafira and even the humble Meriva. The original Astra VXR joined them in 2005 and instantly became the best-seller in the VXR range.

More recently, the range has been rationalised and now extends to just four models: the Corsa VXR/VXR Nürburgring, new Vauxhall Astra VXR, Insignia VXR and VXR8 family, including the VXR8 GTS, Maloo and Sports Tourer.

• Vauxhall Zafira Tourer, 2012

Vauxhall has confirmed that the Zafira Tourer concept, previewed at the 2011 Geneva Motor Show, will become a production reality, with first cars in UK showrooms by early 2012.

Called the Vauxhall Zafira Tourer, the new model will sit above the current Zafira model in Vauxhalls line-up and is set to raise the bar for design, luxury, flexibility and innovation in the MPV sector.

The production cars design, shown in these first official images, has deviated very little from the Geneva concept, illustrating design-chief, Mark Adams continued influence on the look of all new Vauxhall products, and reinforcing his Sculptural artistry meets technical precision mantra.

While the Vauxhall Zafira Tourer will continue to use Flex7 seating, which set new standards for seven-seat integration in the original 1999 Zafira, the system has evolved radically in the new car to offer even greater levels of flexibility, innovation and comfort. Improved material quality, more cabin space and an overwhelmingly airy cabin further define the Vauxhall Zafira Tourer from its compact MPV Zafira sibling.

The Vauxhall Zafira Tourer will also hold great driver appeal. A new chassis, using key components from the Insignia, with a longer wheelbase (complementing its 190mm increase in overall length) and wider tracks, will provide outstanding dynamics, while offering occupants more cabin space and ride comfort. Vauxhalls acclaimed FlexRide adaptive damping system - a rarity in this class - will also be available as an option.

A great emphasis has been placed on safety in the Vauxhall Zafira Tourer, with a plethora of driver-assist systems making a first appearance in the new model. Traffic Sign Recognition, Side Blind Spot Alert and Advance Park Assist - which helps drivers find an adequate parking space and guides them in to it - are among the option highlights.

Two new engines - a 1.4 Turbo petrol and a 2.0 CDTi diesel (with three outputs) - join a 1.8-litre petrol unit to offer a spread of power options from 110PS to 165PS.

The Vauxhall Zafira Tourer will receive its world debut at the 2011 Frankfurt Motor Show (Sept. 15-25).

INTERIOR - limousine-like quality and space combined with new levels of flexibility
Flex7 was a revelation when it was launched in the original 1999 Zafira, offering owners the ability to transform their car from a five- to a seven-seater quickly and simply. While the Vauxhall Zafira Tourer retains the basic concept of Flex7, its made significant improvements in the way it functions.

The entire third row can still be folded flush with the floor of the luggage area, but rather than being a bench, the second row now comprises three separate seats that can be folded and moved fore and aft through 210mm, giving third-row passengers the potential of extra room compared with the current Zafira.

Passengers in the second row also benefit from new levels of space and versatility. Thanks to a clever folding mechanism (available on certain models), the back of the middle seat now folds forward and rotates, providing occupants in the outer seats with individual armrests. So configured, the outer seats can move fore and aft through 280mm (+80mm compared with the current Zafira) and also move by 50 millimetres towards the centre of the car, giving passengers improved shoulder and elbow room, and the feeling of limousine-levels of space and comfort.

The Vauxhall Zafira Tourers load volumes have also increased over the existing Zafira. In five-seat mode, the luggage area can now hold up to 710 litres (up 65 litres versus current Zafira), and up to 1860 litres (+40 litres) when all rear seats are folded.

FlexConsole, a central storage system running between the front seats (similar to that found in the Meriva), allows occupants to keep the large cabin tidy and ordered. An armrest module, incorporating a stowage cubby, and a cup holder slide and lock into the desired position, giving front passengers greater flexibility while theyre on the move.

For the first time in a Zafira model, a new-generation FlexFix is also available. The integrated bicycle carrier neatly fits into the rear bumper and pulls out like a drawer to accommodate two bikes, without the need for any special fixing tools.

DESIGN - premium and spacious with quality materials and surfacing
When Vauxhall unveiled the Zafira Tourer concept at Geneva, Mark Adams - Vauxhall/Opels Vice President of Design - pronounced it a "lounge on wheels", combining high degrees of luxury with flexibility and spaciousness.

This principle has been retained for the production car. Its distinctive front end, with strong centre crease and twin-trapezoidal grille, is quite unique on a car in this class. Large, boomerang graphics sweep from the top of the headlights to the bottom of the fog lamps and frame the grille. As with other models, the headlights feature Vauxhalls wing-shaped daytime running light graphic.

The streamlined, aerodynamic design of the Vauxhall Zafira Tourer features a belt line that sweeps upwards and visually propels the vehicle forward, while the Vauxhall blade sculpts and adds motion to the body-side.

The wing-shaped graphic from the headlights is repeated on the tail lamps. A horizontal bar carrying the Vauxhall logo extends into the light elements, giving the Vauxhall Zafira Tourer a broad, sporty look at the rear.

Special attention has also been given to the design of the interior, too. Visibility has been improved thanks to a completely re-designed front layout, with slim A-pillars, large side windows and re-positioned door mirrors (now fixed directly to the door panel).

Enhancing the Vauxhall Zafira Tourers feeling of airiness still further is an optional Panoramic Windscreen which combines with a generous glass sunroof on certain models.

CHASSIS - improved dynamics and the rare-to-class option of adaptive damping
Compared with the current Zafira, the Tourers wheelbase and tracks have all grown substantially, improving both the ride and stability of the car. The wheelbase is now 2760mm (+57mm), while the tracks are 1584mm at the front (+96mm) and 1588mm in the rear (+78mm).

The Vauxhall Zafira Tourer takes its front axle from the European Car of the Year-winning Insignia, which means an isolated sub-frame and Mac Pherson struts. At the rear, the Tourer retains a compound crank rear axle (similar to the current Zafiras) but adds a Watts link, making it a unique set-up in the MPV class. The compound crank/Watts link combination suits this type of vehicle well, offering excellent space efficiency, light weight and high levels of stability/control.

Enhancing the base chassis dynamic prowess will be the option of Vauxhalls FlexRide adaptive damping system, a rarity in the MPV class. FlexRide automatically adapts the cars damping to suit road conditions, cornering speed, vehicle movements and an individuals driving style. In addition, drivers can select from a choice of three settings - Standard, Tour and Sport - to provide more ride comfort or body control on a continual basis.

SAFETY - intelligent safety systems add to driver appeal
A raft of innovative driver assistance systems have been built into the Vauxhall Zafira Tourer or are optional on certain models.

    An all-new, radar-based Adaptive Cruise Control (ACC) with Collision Mitigating Braking (CMB) constantly monitors the distance to the vehicles ahead and reduces vehicle speed or, in extreme cases, applies emergency braking to prevent a collision
    A front camera system, featuring Lane Departure Warning (LDW) and Traffic Sign Recognition (TSR). The camera also supports...
    Following Distance Indication (FDI) - visually informs the driver about the distance to the vehicle in front
    Forward Collision Alert (FCA) - warns driver via visual and acoustic signals about an imminent collision with the vehicle ahead

In addition, the Vauxhall Zafira Tourer can be equipped with the following technologies:

POWERTRAINS - new petrol and diesel engines join Vauxhall Zafira Tourer range
The Vauxhall Zafira Tourers diesel engine range will comprise three versions of Vauxhalls Euro-5 compliant 2.0CDTi common rail unit, also found in the Insignia and Astra. Power outputs start with a choice of either 110PS or 130PS, while the most powerful engine has been upgraded to produce 165PS.

The petrol range comprises a downsized 1.4 Turbo unit, producing 140PS, and a naturally aspirated 1.8-litre with 140PS. Availability of Start/Stop on certain petrol and diesel engines will be revealed later in the year.

Six-speed manual transmissions will be standard with all 1.4T and 2.0 CDTi engines, with the option of a six-speed automatic on certain models. A five-speed manual box is available with the 1.8-litre petrol model.

Since the Vauxhall Astra GTC shares no body panels with either the Astra Hatch or Sports Tourer, it has a unique appearance in the range, and one which has largely stayed faithful to the stunning 2010 GTC Paris concept.

"We wanted the Astra GTC to be the ultimate expression of Vauxhalls design language, and to embody our passion for the motor car," said Mark Adams, Vice President of Vauxhall/Opel design. "But we didnt want emotion to get in the way of functionality: the Astra GTC still needed to be clever, practical and affordable."

In profile, Mark and his team - a significant number of whom are fellow Brits - created tension in the GTCs shape by minimising the lines running along the body. Vauxhalls signature blade, a crisp line that sweeps up from the rocker at the front of the door, is now similar to the Insignias, but runs the opposite way to other Astras. A second line strikes through the door handle, stretching to the rear, while a third line follows the roofs profile, guiding the eye to the sharply integrated spoiler.

At the front of the car, a centreline crease is complemented by slim, eagle-eye-style headlamps featuring wing-shaped daytime running light graphics. A chrome emblem bar running across the dramatic trapezoidal grille - mounted lower than on other Astras - completes the picture from the front.

Equally dramatic is the GTCs rear treatment. Its powerful shoulder section gives the car imposing proportions and a purposeful road presence. The line from the C-pillar wraps around the tail and the rear spoiler, which in turn integrates with the roofline. LED rear lighting - optional across the GTC range - highlights the stretched wing motif created by the tail lamps.

The Vauxhall Astra GTC has a Cd figure of just 0.33.
Standard on both Sport and SRi trims are 18-inch alloy wheels, with each getting a unique design. For the first time on a Vauxhall coupe in this class, 20-inch rims are available as an option on SRi models, with 19-inch wheels a further cost option on both trims.

On the upper-spec SRi model, tinted glass is standard, while the latest generation AFL (Adaptive Forward Lighting) is optional across the GTC range.

Interior
Despite the GTCs rakish exterior appearance, unlike many of its competitors, interior accommodation and functionality have not been compromised.

Not only can the GTC accommodate five adults, but its luggage compartment provides between 380 and 1165 litres of volume - over 200 litres more than some of the competition.

In line with the current Astra, storage volume in the cabin has also been improved by 50 per cent versus the old Sport Hatch, with items like the electronic park brake liberating space around the console in SRi models.

High quality materials feature in all GTCs, as do chrome-edged instruments in deep-set binnacles that give drivers clear and well laid-out information. Standard on all GTCs are DAB stereo and USB functionality, while SRi drivers get an onboard computer and leather-rimmed steering wheel, among many other standard items.

Two new colours - Seashell and Flaming Yellow - and a selection of new materials, bespoke to the GTC, set the car apart from others in the Astra range. Morello Red, and a new premium leather trim, is also available as an option and brings with it a six-way adjustable drivers seat.

CHASSIS
The Vauxhall Astra GTCs appeal runs far deeper than its rakish lines. Unlike many three-door versions of existing compact hatches, the GTC - like the Astra Sports Hatch before it - will be a standalone model in Vauxhalls range, conceived to resonate with a more driver- oriented customer base who value the way a car handles and performs as much as the way it looks.

To do this, engineers from both Vauxhall Engineering Centre at Millbrook and Opel in Rüsselsheim have developed a bespoke platform for the GTC. Key components - such as the HiPerStruts used on the front axle - have been derived from the 325PS Insignia VXR, while significant upgrades have been made to the GTCs unique Watts link/compound crank rear end. So while the GTC line-up currently includes a broad range of engines producing from 120 to 180PS, drivers can always be assured of class-leading levels of dynamic control.

But the best chassis can only be honed through intense testing on the most demanding surfaces. Britain will be by far the biggest market for the GTC, which is why Vauxhall and Opel engineers have conducted much of their evaluation on UK roads, with their unique (and some may say diabolical) blend of undulations, cambers, rough surfaces, blind apexes and crests. The theory is this: if the GTC can work well in the UK, it will work much more effectively on other markets roads, too.

High tech front suspension boosts GTCs appeal
From the start of the GTCs development programme the target was to deliver a driver-oriented feel to the car, and one that worked well on UK roads. "Our aim was to exceed the best in class with the GTCs dynamics," said Gerry Baker, Vauxhall Engineering Centres chief dynamicist. "We also wanted to change the emphasis in steering and damper-feel from the regular Astra Hatch to a set-up that was more focused, yet still comfortable enough for British roads and drivers."

Much of the development centered around the introduction to the GTC of Vauxhalls HiPerStrut, a first for an Astra model. Based on the system currently seen on the 325PS Insignia VXR, the HiPerStrut uses the Astras existing pick-up points, but reduces the kingpin inclination angle by 44 per cent and shortens the spindle length (kingpin offset) by 46 per cent versus the MacPherson strut-equipped models. This helps prevent torquesteer - a trait of many powerful front-wheel-drive cars - allowing drivers to make more use of the GTCs performance without the steering being corrupted.

Adding the HiPerStrut has also reduced the amount of camber change on the GTCs front wheels during cornering, improving grip. Steering feel is enhanced, too, helped by a reduction the steering systems friction levels. The geometry changes brought by the HiPerStruts also mean that the GTC can be fitted with wheels of up to 20-inches in diameter.

Rear suspension revisions complement GTCs ride-height & track changes
Compared with the Astra Hatch, the GTCs ride height has been lowered by 15mm, while the wheelbase has grown by 10mm, from 2685mm to 2695mm. Both tracks are wider, too, at 1584mm (+40mm) front and 1585mm (+30mm) rear.

The Astras GTC compound crank/Watts link rear suspension system has also been revised, with bespoke roll-stiffness and roll-centre height settings for this application. The system has many advantages over a modern multi-link design, including improved packaging, greater wheel camber stiffness and reduced suspension friction. The Watts link also ensures that lateral stability is maintained at all times.

The Watts link is carried on a small cross-member attached to the underside of the car, just behind the rear wheel centre line. It comprises a short, pivoting centre link with a ball joint at each end, to which the lateral links from the wheels are bolted.

In a straight line, the set up ensures excellent stability, but during cornering it minimises lateral deflection in the same way a modern multi-link system would do. Vauxhalls engineers estimate that the linkage absorbs around 80 per cent of all lateral loadings on the rear suspension. In addition, the Watts link allows for softer bushings, which no longer have to compensate for toe changes at the rear of the car, and thus provide greater compliance and ride comfort from the rear axle.

Unique steering programme for UK drivers
Precision, Feedback & Confidence. These were the three target elements for the GTCs UK-specific steering programme. The challenge was to maintain the systems ease of use at lower speeds, but dial in a greater degree of involvement and slightly more effort at higher speeds.

The Vauxhall Astra GTC uses a rack and pinion steering system with speed sensitive assistance. But in order to provide drivers with more steering feedback, the systems electric motor is mounted directly on the steering rack, as opposed to the base of the steering column.

The key benefits of using an electric power steering (EPS) are well known. At low speeds, the level of power assistance is increased to minimise steering effort. At higher speeds, assistance is automatically reduced to ensure a high degree of steering feel for the driver. The second important benefit is that, because it does not require an energy consuming hydraulic pump and responds directly to the amount of power needed at any speed, fuel consumption is also reduced.

FlexRide enhances GTCs driver appeal still further
FlexRide, Vauxhalls adaptive damping system, will be available as a £790 option across the GTC range, complementing the significant revisions to the new models chassis. FlexRide automatically adapts to prevailing road surfaces and driving styles, providing drivers with fully optimised handling, even in the event of an emergency situation.

At the heart of FlexRide is the Driving Mode Control (DMC) which oversees and executes the systems settings, allowing the car to react to sudden changes in driving style or emergency situations. For example, if the driver needs to avoid an obstacle while in Tour mode - the softest of the three settings - chassis sensors convey this to the DMC and the dampers are adjusted in a split second.

Standard mode (the default setting) reacts in the same way as Tour, but when drivers select Sport they not only get stiffer dampers, but more steering effort, sharper throttle response and an instrument panel thats back-lit in red, rather than white. Each of these settings can be dialled in or out of Sport mode via the GTCs configurator.

British roads: the ultimate challenge for dynamicists!
Vauxhall and Opel engineers are making increasing use of British roads as a key part of their overall chassis development programmes. In the last three years, the Insignia, Astra, Astra Sports Tourer, Meriva, and now the Vauxhall Astra GTC, have all benefited from the UKs unique mix of road surfaces.

1.4-litre Turbo
Strong performance and flexibility are the core strengths of this engine, which is available with either 120PS or 140PS power outputs. Torque generation is even more impressive, with 200Nm available in both engines from just 1,850rpm to 4,900rpm, translating to a 0-60mph acceleration time of 9.0 seconds (140PS) or 10.2 seconds (120PS).

The water-cooled turbocharger, spinning at up to 200,000 rpm, is integrated into the exhaust manifold, close to the engine, for a fast throttle response. Air-to-air intercooling increases the intake charge density.

The adoption of a steel crankshaft with reinforced pistons and con-rods allows the use of a relatively high 9.5: 1 compression ratio, despite higher stresses and loads. Under-skirt piston oil cooling jets and exhaust valves filled with sodium are further measures to ensure durability under higher internal temperatures.

All 1.4 Turbo models come equipped as standard with Start/Stop, helping them achieve competitively low emissions of between 140-142g/km, depending upon wheels/tyres fitted.

1.6-litre Turbo
The most powerful engine in the Vauxhall Astra GTCs line-up produces 180PS and achieves a specific output of just over 100PS per litre. Available across the range, the 1.6 Turbo is the most powerful series production engine in its displacement class.

Its high power is matched by an impressively wide plateau of torque, with 230Nm available from 2,200rpm to 5,400rpm. With this engine, the GTC can accelerate from 0-60mph in 7.8 seconds, and on to a top speed of 137mph.

The 1.6Ts cylinder barrels are laser-etched for minimal piston friction. To withstand higher operating temperatures, the exhaust valves are filled with sodium and under-skirt piston cooling with oil jets is used. A map-based thermostat control raises the coolant temperature at low engine speeds, or under light loads, to help reduce internal lubricant friction and improve fuel consumption.

Diesel engines
All Vauxhall Astra GTC diesel engines are fitted with:
    16-valve, dual overhead camshafts
    A weight-saving aluminum cylinder head
    Threaded intake ports for exceptional swirl and burn characteristics
    Oil jet cooled pistons
    A dual-mass flywheel and a maintenance-free exhaust particulate filter

Common Rail, Multiple Fuel Injection
Operating at high pressures up to 1,800 bar, this sophisticated fuel delivery system ensures extremely fine atomisation in the combustion chamber and enables up to five injection pulses per cycle to extract as much energy as possible from a given amount of fuel. The result is exceptionally low fuel consumption and exhaust emissions, as well as reduced engine noise. Multiple injection helps iron out the strong vibrations associated with compression ignition. For example, a pre-injection during the warm-up period reduces cold-start knock to a barely perceptible level.

Variable Geometry Turbocharger (VGT)
The pitch of the vanes on the turbine wheel is continuously varied according to engine load and speed, giving an excellent throttle response, particularly during pick up from low speeds.

Improved Exhaust Gas Recirculation (EGR)
The electronically-controlled EGR system has an additional cooling function. Electro-pneumatically operated bypass flaps, controlled by the engine management system, ensure that the exhaust gas reaches a temperature suitable for combustion on its way back into the cylinder. This contributes to increased power, as well as reduced emissions.

The diesel line-up comprises:

1.7 CDTi
Available in two states of tune, providing either 110PS and 280Nm of torque, or 130PS and 300Nm. Combined cycle fuel consumption for both is 62.8mpg with standard wheel rims fitted, and each achieves 119g/km. Despite being the most frugal models in the range, the 1.7 CDTis allow the GTC to accelerate to 60mph in either 10.0 (130PS) or 11.0 seconds (110PS). In 2012, an ecoFLEX model using a version of this engine will be available in the UK with emissions of just 109g/km. Start/Stop is fitted to all 1.7 CDTi models as standard.

2.0 CDTi
The 2.0 CDTi packs 165PS with an exceptionally strong 350Nm of torque from just 1,750rpm. This helps it achieve a 0-60mph time of just 8.4 seconds and 50-70mph in 6.4 seconds, together with a combined fuel consumption of 58.9mpg and emissions of just 127g/km (18 & 19-inch wheels fitted). Vauxhalls Start/Stop system is fitted to all 2.0 CDTi models as standard.

Hydraulically-damped mountings for improved NVH performance
All powertrains are bolted in position via hydraulically-damped mountings that minimise vibration through the body structure. Adaptor plates enable the same four fixing points to be used for all applications, two on the front sub-frame and one on each longitudinal beam.

The fuel supply system uses an electric pump and filter mounted in the 56-litre fuel tank, which is located low under the rear seat for optimal weight distribution and crash impact protection.

Start/Stop reduces emissions, improves urban fuel consumption
Vauxhalls Start/Stop technology, which is available on all 1.4 Turbo, 1.7 CDTi and 2.0 CDTi engines, is highly efficient and helps to reduce emissions. As soon as the driver selects neutral, the Start/Stop system is activated and the engine unit cuts out automatically. The rev counter needle then assumes the Autostop position. When the driver wants the engine to start up again, he/she just selects first gear and departs. A powerful battery ensures that there is no delay in the engine starting up again.

For safety reasons and to ensure the comfort of passengers, the temperature and pressure functions of the brake power assist unit remain active during the Auto-Stop phase of the Start/Stop system. When necessary, for example during slow city traffic, the driver can manually de-activate the system, using the "eco" switch.

Transmission
Six-speed manual gearboxes, offering a wide spread of ratios and a tall, fuel-saving top gear, are standard fit across the entire range. All gearboxes include triple cone synchronization on first and second gears for easy engagement, and a synchronized reverse gear.

A six-speed automatic gearbox is also available on 1.4 Turbo 140PS and 2.0 CDTi 165PS engines.

MARKET
The all-new Vauxhall Astra GTC replaces the successful Astra Sports Hatch, and will lay down the gauntlet to VW Scirocco and Renault Megane Coupe when it appears in showrooms at the end of November 2011 with a heady mix of dynamic excellence, dramatic design and competitive pricing.

Closely based on last years stunning GTC Paris concept, the Vauxhall Astra GTC enters the UK market - the biggest in Europe for this model - priced from just £18,495, nearly £1,350 less than the basic VW Scirocco. But even in entry-level trim, the Vauxhall Astra GTC adopts the sophisticated HiPerStrut front suspension derived from the Insignia VXR, offering precision handling and unmatched stability.

The third body style to come off the Astras Delta platform (following the Hatch and Sports Tourer), the only exterior design elements the GTC shares with its siblings are door handles and the roof aerial - even the wheelbase and tracks are different. Brit, Mark Adams, Vauxhalls Vice President of Design, has aimed to create a car that looks like its been plucked from the class above, with its low, wide stance and simple, yet rakish lines.
