The Mercedes SLS AMG E-CELL is a zero-emission electric prototype car with a power output of 535 hp and 880 Nm of torque.
Mercedes says that the SLS AMG E-CELL offers the prospect of a possible small series production run.
The SLS AMG has four synchronous electric motors with a combined peak output of 525 hp 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 the wheels meaning that compared with wheel-hub motors the unsprung masses are substantially reduced.
The gullwing model also accelerates from zero to 100 km/h in 4 seconds – which almost puts it on the same level as the SLS AMG with 6.3-litre V8 engine developing 571 hp, which can accelerate to 62 mph in 3.8 seconds.
Maximum torque is also available virtually from a standstill as the torque build-up with an electric motor is instantaneous. And of course four motors and four wheels means permanent all-wheel drive.
The SLS AMG E-CELL drive incorporates a liquid-cooled 400-volt lithium-ion battery, consisting of 324 lithium-ion polymer cells.
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.
Mercedes says the SLS was conceived as both a petrol and an electric-powered model from the outset.
