New engines for Mercedes A Class
With three petrol and three diesel engines, Mercedes-Benz A-Class will go live in September. For the first time will be with the A 180 CDI Mercedes-Benz including one that emits only 98 grams of carbon dioxide per kilometer. And for the first time with the A 220 CDI Mercedes meets a Euro 6 emissions standard that is before 2015 rule.
The motors can be combined with the new six-speed manual or optional automatic transmission with double clutch transmission 7G-DCT, the comfort and sportiness in a special way with each other. All engines of the new A-Class are equipped with a start-stop function
Consume up to 26 percent less than the new engines of comparable previous models, and the significantly enhanced performance. Diesel: The new base engine makes the OM 607 80 kW / 109 hp, roughly half maximum of 260 Newton meters (Nm) of torque to the crankshaft and with manual transmission consumes 3.8 liters per 100 km, corresponding to 98 g CO2/km - an improvement of 22 percent compared to only 60 kW / 82 hp predecessor, A 160 CDI, which consumed 4.9 liters.
Even 25 percent is better than its predecessor, the new A 220 CDI Diesel Top: He 125 kW / 170 hp, 350 Nm offers and consumed in combination with the dual-clutch automatic transmission 7G-DCT only 4.3 litres/100 km. The data from the A 200 CDI predecessor: 103 kW / 140 hp, 5.7-liter, 149 g CO2/km.
An example of the gasoline engine is the comparison against new A 200 A 200 so far: With 115 kW / 156 PS and 250 Nm of torque, the newcomer good performance, consumes 5.5 liters per 100 km (129 g CO2/km) but 26 percent less than its predecessor (100 kW / 136 hp, 185 Nm, 7,4 l/100 km, 174 g of CO2/km). Even with the new top-7G-DCT and 155 kW / 211 PS and 350 Nm, with a consumption of 6.1 liters and CO2 emissions of 143 g significantly more efficient.
Crucial for the efficiency it is not just the consistently new engines and transmissions. Thanks to the modular system for diesel and gasoline were each optimally designed gears are selected. The complete package also pioneering aerodynamic drag coefficient of 0.27 with a bear and a number of other optimizations at.
Since its world premiere in 2008 is under the name of the OM 651 known direct-injection diesel engine standards in performance and torque characteristics, economy, exhaust emissions and quietness. It is as universal as any Mercedes-Benz diesel engine used before. For transverse installation of the belt drive of the ancillaries, the turbocharger mounting position and the air flow was changed. In the new A-class match three versions are used: to drive dynamic, extremely efficient and extremely clean, the A 220 CDI, which only in combination with the 7G-DCT dual-clutch transmission is available. The 125 kW / 170 PS strong Topdiesel has a weight-optimized crankshaft and comes with screw-down of individual bearing caps and four counterweights, about six pounds less on the scale as a displacement in the same OM651 longitudinally mounted version. The single-stage turbocharger is sized larger than the versions with 80 and 100 kW.
The A 200 CDI is equipped with a multi-way exhaust gas recirculation (EGR), which reduces nitrogen oxide emissions. Is taken in addition to high-pressure EGR, the hot exhaust manifold and the fresh air on the side behind the charge air cooler is introduced, taken from there at a lower pressure level exhaust gas. This so-called low pressure EGR branches off the cleaned exhaust gas according to the diesel particulate filter, cools it and supplies it with the aid of a valve to the fresh air stream upstream of the turbocharger back. The engine already meets the mandatory from 2015 Euro 6 emissions standard. With 112 g CO2 per kilometer, the A 220 CDI sets new standards in its segment. With 2.2-liter engine is the comparatively large volume and so agile at low speeds.
"Downspeeding" is what the engine specialists at Mercedes-Benz engine and the combination of large low speeds. This could shift the program "Economy" emphasizes the 7G DCT economically and conveniently be interpreted. If the driver, however, the shift in the "S" is connected much faster, and the gear ratios using the reserves of the engine speed for optimum dynamics. The performance of the A 220 CDI - available in Blue Efficiency and sports - are at 7.8 seconds for the standard sprint and 227 km / h at a high level.
Systematically transferred to the Mercedes-Benz gasoline engines, the Blue-Direct technology from the V6 and V8 engines, the luxury and upper class. The Blue-Direct-four-cylinder gasoline engines for the new A-Class combines spontaneous response and excellent power delivery with high efficiency and class-best emission characteristics. The worlds first "Camtronic" - an innovative valve-lift - helps. In the A-Class is the new four-cylinder engine family with 1.6 or 2.0 liter engine to choose from, covering a range of 90 kW / 122 hp) and 200 Nm to 155 kW / 211 PS and 350 Nm.
With BlueDIRECT with high-precision piezo-injection, the new engines meet the applicable date from 2015 Euro 6 emission standards for gasoline engines. Even the once stringent diesel particle number limit value of the Euro-6 standard is not reached without additional exhaust treatment today. This was a major motivation, BlueDIRECT use in this segment. The completely newly developed four-cylinder gasoline engine generation is thus prepared for the future. Basis for all three petrol engine versions of the new A-Class is the all-aluminum engine M 270 with two overhead, chain-driven camshafts and four valves per cylinder. The unit is versatile and will be introduced gradually in larger series. In this way it helps to reduce production costs. The four-cylinder can be transverse (M 270) or a combination of longitudinal (M 274) and fit with front-, rear-wheel drive or 4Matic. For the power transmission allows manual gearbox, automatic conversion or double-clutch gearbox can be used.
In the new A-class of M 270 is available in three levels. A 180 Blue Efficiency as he does from 1595 cc engine capacity 90 kW / 122 hp with maximum torque of 200 Newton meters, the (r / min) over a wide speed range 1250-4000 rpm is available. With the base engine and six-speed manual (or the seven-speed dual-clutch gearbox) accelerates the new Mercedes A-Class in 9.2 seconds (9.1 seconds) from zero to 100 km / h and if necessary, up to 202 km / h (202 km / h) fast. Fuel consumption and CO2 emissions are 5.5 l/100 km (5.4 l/100 km) and 128 g / km (127 g / km) at a record low level.
