The Mercedes-Benz SLS is not for everyone, but it never fails to turn heads. Add the AMG badge and you know it’s built for performance. Now MB is giving it full electric drive. Powerful and locally emission-free.

Key performance data at a glance:

• Max. output: 392 kW
• Torque: 880 Nm
• 0-100 km/h: Approx. 4 s
• Rated capacity: 40 Ah (at 400 V)
• Energy content: 3x 16 kWh = 48 kWh

From Mercedes-Benz press release:

… forwards (sic) thrust is provided by four electric motors with a combined peak output of 392 kW and a maximum torque of 880 Nm. The four electric motors are positioned near the wheels, substantially reducing the unsprung masses compared to wheel-hub motors. One transmission per axle transmits the power. This intelligent all-wheel-drive system allows dynamically optimised power transmission without any losses by means of Torque Vectoring – in other words the specifically targeted acceleration of individual wheels. In its first pilot phase, the SLS AMG with electric drive incorporates a liquid-cooled high-voltage lithium-ion battery of modular design with an energy content of 48 kWh and a capacity of 40 Ah. The 400-volt battery is charged by means of targeted recuperation during braking whilst the car is being driven.

… the swing-wing model accelerates from zero to 100 km/h in around 4 seconds – putting it on the same high level as the SLS AMG with a 6.3-litre V8 engine developing 420 kW/571 hp.

The electrically powered SLS AMG sees Mercedes-Benz and AMGcontinuing to pursue their aim of minimising the amount of time it takes to bring about the electrification of the car. Their strategic involvement in Deutsche Accumotive GmbH & Co. KG, a joint venture between Daimler AG and Evonik Industries AG, will provide the battery technology required in future. Daimler has the leading role in this joint venture for the development and production of batteries and battery systems for automotive applications.

A few other highlights:

Wide-opening swing-wing doors for easy entry even in garages …

At the design stage great attention was paid to the widest possible opening angle – it is a full 70 degrees.

… another important criterion for dignified access and egress, two gas-pressure struts positioned next to the door hinges require only very little pressure when opening and closing the doors – even at very low ambient temperatures.

The swing-wing doors require less opening space than conventional coupé doors, and can be fully opened in a normal garage.

By the way, I like MB’s description of this electric car as “locally emission-free.” A very responsible marketing and PR step. The other manufacturers should do the same.
