The text says it’s the new B-Class, and that it also will feature an electrical motor, according to Thomas Wever, R&D boss of MB. In 2009, a fuel-cell B-Class will be released (an expensive small-series), one year later a full-electric. No price was given, but it won’t be cheap.
In 1997, with the first A-Class and its sandwich-floor, an electrical motor in this sandwich floor was already seen as a possibility. Now it’s becoming reality with this Blue-Zero Concept, presented in Detroit.
Three versions will be presented: all of them have an electric motor. One will be all-electric, another will add a fuel-cell to the electric motor, the last will add the 3-cylinder of the Smart to the electric motor to boost the autonomy and produce electricity (hybrid). They will be called the BlueZero E-Cell, F-Cell, E-Cell Plus.
The electric motor produces 100 KW maximum (70 KW normally) and 320NM of torque. Less than 11 seconds to 100 km/h, mx 150 km/h (to save energy).
But the car doesn’t spare anything other than the energy. 5 places, 500l of luggage space, Li-Ion batteries which are refrigerated, 200km autonomy for the all-electric model. Filling the batteries cost around 2,70€, with a capacity of 15,3 KW/h. 3 to 4 hours are needed to fill it on your conventional home-electricity.
The Fuel-Cell version has more autonomy, can be started easily even at -25° Celsius. Only the electric motor is used when parking the car, when accelerating both electric and fuel-cell motors are used like in an hybrid. Braking-energy is of course recuperated. The autonomy is 400kms, the problem is to find the Hydrogen..
The hybrid-model has the electric motor plus a 68hp Smart-3 cylinder petrol engine placed where the sparewheel usually is. When driving, this motor is re-charging the batteries, so the autonomy is 600kms. Average consumption, 4,5l of petrol every 100kms.
The electric cars sold in series will only come in 4 years, though…
Good ideas are worth it. Example, the Sandwich-concept of the A-Class… it is particularly adapted to electrical cars!
