Mercedes-Benz to Introduce New-Generation A- and B-Classes at Leipzig Show; Start/Stop Function on High-Volume Models
|The new-generation A-Class.|
Mercedes-Benz will introduce its new-generation A- and B-Class vehicles at the Auto Mobil International (AMI) motor show in Leipzig (5-13 April). The new line-up features a number of fuel-saving enhancements, including a start/stop microhybrid function on high volume A- and B-Class vehicles. The B-Class is also now available with a gasoline/natural-gas drive system.
Fuel consumption for the standard new-generation A-Class models range between 4.9 and 8.1 liters per 100 kilometers (48 to 29 mpg US). Fuel consumption of the direct-injection diesel engines has been reduced by more than 8 percent or 0.5 liters per 100 kilometers compared with the outgoing models.
Mercedes is adding a start/stop function to the high-volume A 150 and A 170 models, resulting in up to a 9% reduction in fuel consumption for the vehicles when driving in city traffic. Mercedes-Benz has also developed an additional BlueEFFICIENCY package for the three-door A 160 CDI, reducing the Coupé’s fuel consumption to 4.5 liters per 100 kilometers (51 mpg US).
The BlueEFFICIENCY package, available in the autumn of 2008, further improves engine efficiency, aerodynamics, rolling resistance, energy management and weight. CO2 emissions of the 60 kW/82 hp coupé are 119 grams per kilometer. The BlueEFFICIENCY package includes an aerodynamically optimized radiator grille, the rear side of which is sealed off, thus reducing the volume of air flowing into the engine compartment. Despite this, sufficient cooling for the CDI engine is ensured at all times.
The bodywork has also been lowered by 10 millimeters to further reduce wind drag. The Mercedes engineers have leveraged further potential to save fuel by dynamically controlling the power supply on board the A 160 CDI BlueEFFICIENCY to save energy. The generator management system consistently converts the power generated when the engine decelerates (i.e. on the overrun) into electrical energy, which is then used to recharge the battery in an optimum, energy-efficient manner.
Mercedes-Benz has also revamped the design and technology of the B-Class. The four-cylinder engines now burn up to 7% less fuel than before, and exceed current EU emissions limits by as much as 90%. The new ECO start/stop function is available for the high-volume B 150 and B 170 models. Another new development for the B-Class is the bivalent gasoline/natural-gas drive system in the B 170 NGT BlueEFFICIENCY, which consumes 4.9 kilograms of natural gas per 100 kilometers. Converted into the equivalent quantity of gasoline energy, the fuel cost per kilometer is around 50% less than when running on gasoline.
