Mercedes Benz BlueZERO: all the details

 16 Dec 2008 - By Omar Yesid Mariño+

Last week, we talked about the Mercedes’ new “green” prototypes, but today the group Daimler has published all the details about this car line. Maybe you remember that BlueZERO E-CELL (you can see it in the picture), F-CELL and E-CELL PLUS are three concepts in pure electric, gas-electric hybrid and hydrogen fuel cell versions that, under their conceptual definition, are an advance in design, as well as in the green models that Mercedes has been developing in its laboratories.

Mercedes Benz BlueZERO: all the details

These three prototypes, which are apparently identical except for their colors (yellow, green and orange respectively), measure 4.22 m in length and seating for five, offering a cargo capacity between 450 kg and 500 kg. These are surprising figures in its class, since the usual thing is the batteries are placed in the car trunk or, at least under one of the back seats. Mercedes has solved the problem with a sandwich-floor architecture that houses the batteries under a “false floor” and the mechanical elements between the axles. The BlueZERO models have low-friction tyres, and aerodynamic improvements like the covers over the back wheels (they are 20-in wheels).

As for the numbers, the three concepts can accelerate from zero to 62 mph in eleven seconds, and in order to optimize the efficiency, they can only reach a maximum speed of 93 mph (150 km/h). Also, they have front traction and,  in the case of the E-CELL model, it depends on a set of  lithium-ion batteries connected to an electric generator with a maximum power of 100 kW and a continuous output of 70 kW. Its peak torque is 320 Nm.

As it could not be otherwise, the electric models can be charged by using any household power socket. They need only 30 minutes to accumulate the necessary energy to travel 30 miles (aprox. 50 km). One hour charge time is enough to travel 60 miles (aprox. 100 km), and obviously, two hours charge time are enough to travel 120 miles (aprox. 190 km). The PLUS version is also supported by a turbocharged three-cylinder engine that has an output of 50 kW (68 HP) and 3,500 rpm. This engine is placed in the back of the vehicle. This way, the E-CELL PLUS offers a surprising range of around 370 miles (aprox. 600 km) by using the engine. On the other hand, if you don’t want to use fuel, it has a range of around 93 miles (aprox. 150 km) in emission-free electric mode.
