The SLS AMG Coupé Electric Drive

Mercedes-AMG is entering a new dimension in Driving Performance with the SLS AMG Coupé Electric Drive – AMG’s most powerful production car.
Developed in collaboration with the Mercedes AMG High Performance Powertrains in Brixworth, this pioneering gullwing model combines the latest in e-mobility with advanced technology from Formula 1. The result is an emission-free super sports car that achieves 0–62 mph in just 3.9 seconds and a blistering 155 mph limited top speed.
Tremendous power comes courtesy of four synchronous electric motors providing a combined maximum Imposing looks complement the supreme driving dynamics. The aggressive diffusers front and rear, darkened headlamps, vented side skirts and AMG 5-twin-spoke light-alloy wheels all bear the marks of a rich motorsport pedigree, while the “Electric Drive” lettering on the side spells impeccable environmental credentials.
The SLS AMG Coupé Electric Drive is only available in Germany, but if you want to catch a glimpse of it in action, check out this weekend’s BBC Top Gear on Sunday at 8:00pm.

the car has an output of 750 bh and torque of 1000 Nm. This is distributed to each of the wheels individually, resulting in incredibly dynamic wheel-selective all-wheel drive, and of course – an unparalleled driving experience. And because the build-up of torque is instant with electric motors, it means that maximum torque is effectively available from standstill.
The trailblazing body shell structure of the SLS AMG Coupé Electric Drive is part of the ambitious "AMG Lightweight Performance" design strategy. The battery is located within a carbon-fiber monocoque which forms an integral part of the gullwing model and acts as its "spine". The monocoque housing is firmly bolted and bonded to the aluminum spaceframe body. The fiber composite materials have their roots in the world of Formula 1, among other areas. The advantages of CFRP (carbon-fiber reinforced plastic) were exploited by the Mercedes-AMG engineers in the design of the monocoque. These include their high strength, which makes it possible to create extremely rigid structures in terms of torsion and bending, excellent crash performance and low weight. Carbon-fiber components are up to 50 percent lighter than comparable steel ones, yet retain the same level of stability. Compared with aluminum, the weight saving is still around 30 percent, while the material is considerably thinner. The weight advantages achieved through the carbon fiber battery monocoque are reflected in the agility of the SLS AMG Coupé Electric Drive and, in conjunction with the wheel-selective four-wheel drive system, ensure true driving enjoyment. The carbon-fiber battery monocoque is, in addition, conceived as a "zero intrusion cell" in order to meet the very highest expectations in terms of crash safety.

The SLS AMG Coupé Electric Drive is slowed with the aid of AMG high-performance ceramic composite brakes, which boast direct brake response, a precise actuation point and outstanding fade resistance, even in extreme operating conditions. The over-sized discs – measuring 402 x 39 mm at the front and 360 x 32 mm at the rear – are made of carbon fiber strengthened ceramic, feature an integral design all round and are connected to an aluminum bowl in a radially floating arrangement.

The purely electric drive system was factored into the equation as early as the concept phase when the super sports car was being developed. It is ideally packaged for the integration of the high-performance, zero-emission technology: by way of example, the four electric motors and the two transmissions can be positioned as close to the four wheels as possible and very low down in the vehicle. The same applies to the modular high-voltage battery. Advantages of this solution include the vehicle's low center of gravity and balanced weight distribution – ideal conditions for optimum handling, which the electrically-powered gullwing model shares with its petrol-driven sister model.
