Mercedes-Benz SLS AMG eDrive revealed

Article by Christian A., on August 27, 2010

Last week we spoke about the new SLS AMG with electric drive, an exciting super sports car with zero-emission high-tech drive. Mercedes-Benz revealed today its expertise in the development of alternative drive solutions for high-performance super sports cars.

Power of this vehicle comes from four electric motors with a combined peak output of 392 kW (525 hp) and an impressive 880 Nm of torque.

According to the manufacturer the four 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.

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 vehicle can sprint from 0 to 100 km/h in just 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. Daimler AG and Evonik Industries AG, will provide the battery technology required in future.

Mercedes-Benz SLS AMG Coupé Electric Drive marries the multi-award-winning design of the SLS AMG and several specific elements exclusive to the Electric Drive variant.

Up front, the SLS AMG Coupé Electric Drive features a front apron with carbon-look CFRP front splitter, while some areas of the radiator grille and adjacent air intakes are finished in the vehicle color and don bionic honeycomb-shaped openings.

Aside from serving a visual feature, these aerodynamically optimized elements help enhance air flow over the cooling modules. The front end is also defined by darkened headlamps.

Meanwhile, the flanks of this version of the SLS AMG is marked by "Electric Drive" lettering, AMG 5-twin-spoke light-alloy wheels with their specific paint design as shod with 265/35 R 19 front tires and 295/30 R 20 rear rubbers. On the tail section, the SLS AMG Coupé Electric Drive is marked by darkened rear lamps and new diffuser-look rear apron.

The SLS AMG Coupé Electric Drive could be wrapped in AMG electricbeam magno, a matt finish only available this car. Customers may also from five other colors, all without any additional charge. When this exclusive finish is picked, the AMG electricbeam magno is employed as the color for contrasting stitching, as coordinated with designo black Exclusive leather appointments.

The car’s high-quality, sporty interior is fitted with AMG sports seats and a number of carbon fiber trim elements, all highlighting the exclusive and dynamic character of the SLS AMG Coupé Electric Drive. A newly designed AMG instrument cluster is positioned behind the new AMG Performance steering wheel, featuring not a rev counter, but a power display that shows information such as battery charge, power requirements, transmission modes and recuperation status.

Meanwhile, the AMG DRIVE UNIT comprises the electronic rotary switch that allows the driver to pick from three transmission modes: "C" (Controlled Efficiency), "S" (Sport) and "S+" (Sport plus).

The S+ button can be used to select certain performance levels from the electric motors, thereby modifying the top speed and accelerator pedal response in the process. Buttons for AMG Torque Dynamics and AMG Setup are found behind the buttons for "power" and "ESP On/Off".
