New Mercedes-Benz A-Class E-Cell with Battery Powered Electric Drive


Mercedes-Benz has taken the wraps off its all-electric A-Class E-Cell electric vehicle that will enter production this fall. The company plans to build 500 A-Class E-Cells and lease the car to selected customers in several European countries, including Germany, France and the Netherlands.

The lithium-ion powered E-Cell is based on the existing A-Class and Mercedes claims it offers the same safety, space and comfort of its petrol-powered sibling.

The E-Cell has a range of 124 miles (200 km) on a single charge and can be recharged either through mains power (which takes eight hours) or at public recharging stations (which takes three).

Nominal output from the electric motor is 68 hp (50 kw) and 95 hp (71 kw) when on boost (i.e. for overtaking). Torque is 290 Nm. Mercedes claims the E-Cell is good for 0 - 37 mph (0 - 60 km/h) in 5.5 seconds and 0 - 62 mph (0 - 100 km/h) in 14 seconds. Top speed is electronically limited to 93 mph (150 km/h).

The launch of the E-Cell coincides with the planned establishment of hydrogen and electric recharge infrastructure in the Baden-W├╝rttemberg region of Germany. In cooperation with Energie Baden-W├╝rttemberg AG, Daimler will provide 700 recharge points and two to three hydrogen refilling stations in the region by the close of 2011.
