Mercedes-Benz has revealed the electric drivetrain system that powers the Mercedes SLS AMG E-Cell project. The drivetrain, which has been in development since 2010, makes use of the German manufacturer’s Formula 1 experience, particularly with the Kinetic Energy Recovery System (KERS).
The E-Cell’s electric powertrain, in development since 2010, has been jointly produced by Merc’s performance arm, AMG, and Mercedes AMG High Performance Powertrains in Brixworth, Northamptonshire.
The system comprises four electric motors located near the wheels that provide a peak power output of 392kW (equivalent to 526bhp) and 649lb ft of torque. The four motors rev to a maximum of 12,000rpm.
The gullwing-doored SLS E-Cell accelerates from 0-62mph in 4.0sec, compared to the 3.8sec taken by the conventionally powered SLS AMG.
Mercedes positioned the motors close to the wheels rather than in the wheel hubs in order to reduce the unsprung masses. The four electric motors and the transmissions are positioned very low down in the vehicle to offer a low centre of gravity and balanced weight distribution.
