Auto Car | 2010 Mercedes-Benz SLS AMG E-Cell Concept | Mercedes-AMG is accepting the challenges of motoring of the future: the SLS AMG E-CELL is evidence of the state-of-the-art development of an exciting super sports car featuring a zero-emission high-tech drive. Boasting a power output of 392 kW and 880 Nm of torque, the technology vehicle from AMG is able to offer exceptional performance. The gullwing with electric drive is part of the company strategy entitled “AMG Performance 2015″ which aims to continually reduce fuel consumption and emissions.
With the SLS AMG E-CELL, Mercedes-AMG is providing a glimpse of its latest development project – a powerful and locally emission-free super sports car. Finished in fluorescent “AMG lumilectric magno” paint, the gullwing offers the prospect of a possible small series production run and at the same time reflects the innovative strength and development competence of the AMG performance brand.
“We take social responsibility very seriously and with the SLS AMG E-CELL we are demonstrating a further milestone in our “AMG Performance 2015″ strategy. It is our goal to continually reduce the fuel consumption and emissions of new models in the coming years, while at the same time enhancing the core brand value of performance”, explains Ola Källenius, chairman of the board (from 1 July 2010) of Mercedes-AMG GmbH. With the SLS AMG E-CELL, the performance brand of Mercedes-Benz is launching a totally innovative drive solution for super sports cars and as such is among the pioneers in this market segment.
The ground-breaking drive system of the technology vehicle boasts some outstanding features: powerful traction is provided by four synchronous electric motors with a combined peak output of 392 kW and a maximum torque of 880 Nm. The four compact electric motors each achieve a maximum rpm of 12,000/rpm and are positioned near to the wheels. As a result, compared with wheel-hub motors the unsprung masses are substantially reduced. One transmission per axle transmits the power.
Acceleration from zero to 100 km/h in 4 seconds
When it comes to dynamics, the electrically-powered SLS AMG makes a statement: the gullwing model accelerates from zero to 100 km/h in 4 seconds – which almost puts it on the same high level as the SLS AMG with 6.3-litre V8 engine developing 420 kW (571 hp), which can accelerate to 100 km/h in 3.8 seconds.
Further exciting touches are provided courtesy of the agile accelerator response and the straight-line performance: unlike the combustion engine, torque build-up with an electric motor is instantaneous – maximum torque is available virtually from a standstill. The spontaneous torque build-up and confident power delivery – which does not suffer from any interruption of tractive power – are combined with engine running characteristics which are totally free of vibration. Four motors, four wheels: the intelligent and permanent all-wheel drive of the electric SLS guarantees driving dynamics at the highest level, while at the same time providing the best possible active safety. Perfect traction is therefore ensured for all four driven wheels, whatever the weather conditions.
This very special gullwing is therefore able to “electrify” the driver with a completely unique, effortlessly superior and emotional super sports car driving sensation – and this is just at the prototype stage. In brief: the SLS AMG E-CELL is a true AMG too.
High-voltage lithium-ion battery provides 400 v and 40 Ah
The SLS AMG E-CELL drive incorporates a liquid-cooled high-voltage lithium-ion battery featuring a modular design with an energy content of 48 kWh and a capacity of 40 Ah. The maximum electric load potential of the battery, which consists of 324 lithium-ion polymer cells, is 480 kW, which is an absolute best value in the automotive sector. Another technical feature of this considerable performance is the intelligent parallel circuit of the individual battery modules – this also helps to maximise the safety, reliability and service life of the battery. The 400-volt battery is charged by means of targeted recuperation during braking whilst the car is being driven.
A high-performance electronic control system converts the direct current from the high-voltage battery into three-phase alternating current which is required for the synchronous motors and regulates the energy flow for all operating conditions. Two low-temperature cooling circuits ensure that the four electric motors and the power electronics are maintained at an even operating temperature.
A separate low-temperature circuit is responsible for cooling the high-voltage lithium-ion battery. In low external temperatures, the battery is quickly brought up to operating temperature with the aid of an electric heating element. This helps to preserve the overall service life of the battery. In extremely high external temperatures, the cooling circuit for the battery can be additionally boosted with the aid of the air conditioning system.
