Mercedes is developing a trio of concept cars it calls BlueZERO.  A modular architecture permits three different drivetrains to be used. The E-CELL version is battery-electric, the E-CELL PLUS is a series-hybrid with a small internal combustion engine driven genset that acts as a range-extender like the GM Volt, and the F-CELL uses a hydrogen fuel cell.

The traction motor is a permanent magnet synchronous design which operates at a maximum of 13,280 rpm.  It develops peak output of 100kW (134hp) and continuous output of 70kW (94hp). Peak torque is 320 Nm (236 lb-ft), continuous output is 180 Nm (132 lb-ft).  The ability of the electric motor to provide full torque from 0 rpm across its full operating range allows the motor to perform as well as a V6 engine at 2500 rpm.

All of the models use lithium-ion battery packs. The battery has a capacity of 35 kilowatt hours (kWh) and is located in the middle of the vehicle,  The battery is protected from collision damage by its location in the "sandwich floor" of the chassis.
The BlueZERO E-CELL PLUS (the plug-in hybrid version) has a range of up to 370 miles, of which 93 miles are in pure-electric mode. After 93 miles, electric power is provided by the 1.0-liter, 3-cylinder turbo engine turning a generator.
