Mercedes has revealed the electric B-Class in the guise of the B-Class Electric Drive Concept – a name Mercedes say will find its way on to the boot of all electric Mercedes, Smart and Tesla cars – which previews a production version by 2014. Powering the B-Class Electric Drive is the Smart electric Drive powerplant, located in the space normally taken up by the ICE, which offers 134bhp and a healthy 228lb/ft of torque with the batteries to power the electric motor housed in what Mercedes are calling the B-Class’s Energy space ahead of the rear axle.
