Mercedes-Benz, BMW show mild model, concept

September 23,

Two new hybrid vehicles are the result of a research project between rivals BMW and Daimler-Benz. BMW is showing a concept creatively namedthe BMW 7 Series ActiveHybrid while is going into production a hybrid version of the S-Class. vehicles are mild gas-electric that is, they’re not able to run on electric motors alone but use an electric motor between the and the transmission for extra power needed to supplement a more efficient combustion engine, a concept to that of the Honda

The production Mercedes-Benz model be known as the S400 BlueHYBRID. on the Mercedes S350, the S400 uses Mercedes’ 3.5-liter adapted to “Atkinson cycle” and the 7-speed 7G-Tronic automatic specially adapted for this The electric motor supplements the motor with a maximum 118 of torque during acceleration.

As other mild hybrid, the has a start/stop function that off the engine when the car is at a standstill and restarts it when the gas pedal is Similarly, when braking the motor works as a generator, adding a braking effect and the hybrid’s batteries.

The S400 BlueHybrid is actually the application of automotive high-voltage battery. The advantage of the lithium-ion says Mercedes-Benzis a higher density and better electrical The resultant smaller dimensions and weight saves fuel and means that none of the room is lost accommodating the

Using Atkinson cycle (leaving the intake valve longer between intake and stroke, thus effectively expansion phase longer the compression phase) Mercedes emissions and fuel consumption of the V-6. Horsepower was increased by horsepower to 279 horsepower.

Mercedes the S400 BlueHybrid accelerates zero to 100 km/h (62 mph) in 7.2 The base model sold in the the S550, clips that off in 5.4 seconds. But while the S550 has an EPA estimate of 14/21 city/highway, the BlueHybrid has a 16/30 rating the European Union cycle, a 23 mpg combined rating.

The mild hybrid system in the BMW 7 Series ActiveHybrid combines the motor” with the a four-liter V-8 direct injection and two turbos into the vee, a la BMW X6 xDrive5.0i. In trim, this engine is at 400 horsepower and 450 lb-ft of torque. The motor of the hybrid adds 20 and 155 lb-ft of torque. Because the and torque peaks of the gas engine and the motor occur at different they can’t be added to get a peak.”

The hybrid 7-er, however, be faster than the standard plus, according to BMW, it reduce fuel consumption and by about 15 percent on the EU test versus the same car with a engine only.

Like the the BMW concept also uses the battery and like the Mercedes is to run all accessories off that battery further increasing the efficiency of vehicles.

Like the co-developed Mercedes the electric motor is sandwiched the engine and transmission, except in the of the BMW there are eight forward which is pretty darn to a continuously variable transmission.

The S400 BlueHybrid goes on in Europe this fall no arrival Stateside announced A production version of the BMW ActiveHybrid won’t reach the market sometime in 2009, probably in the and quite possibly the 5-Series, likely it will go on sale in before making the Transatlantic
