Mercedes Announces SLS AMG Gullwing electric drive

526hp and 880Nm of torque

Mercedes has officially confirmed our earlier report, which indicated the company was going to produce an electric version of the SLS AMG Gullwing.

The zero-emission supercar, tentatively named the SLS AMG eDrive, will feature four electric motors with a combined output of 392 kW (526 hp) and 880 Nm (649 lb-ft) of torque. This will enable the electric SLS to rocket from 0-100 km/h in around 4 seconds, which puts it on par with the standard 6.3-liter (6208cc) V8 powered (571 hp and 650 Nm) SLS that accomplishes the same task in 3.8 seconds.

According to Mercedes, the four electric motors are positioned near the wheels and are connected via one transmission per axle. This unique setup effectively gives the SLS AMG eDrive an intelligent all-wheel-drive system which optimizes power to each individual wheel.

The center tunnel of the SLS eDrive is dominated by a massive liquid-cooled high-voltage lithium-ion battery that has an energy content of 48 kWh and a capacity of 40 Ah (at 400 V). While details are still limited, the battery is recharged via a plug-in system as well as regenerative braking.

Since Mercedes planned to produce an electric SLS from an early standpoint, the company engineered the car so that the low center of gravity and balanced weight distribution would remain virtually identical to the petrol powered variant. The foresight also allows Mercedes to build the electric SLS without making any changes to the car's aluminum spaceframe.

In a statement, Mercedes-AMG GmbH's CEO Volker Mornhinweg said, "With the SLS AMG with electric drive, we wanted to redefine the super sports car. For us, it is not just about responsibility. We attach just as much importance to excitement and classic AMG performance."

Mercedes-Benz SLS AMG with electric drive - the exciting future of the super sports car

New swing-wing model with purely electric high-tech drive system

Mercedes-AMG is paving the way ahead: with the new SLS AMG with electric drive, the performance brand within Mercedes-Benz Cars is developing an exciting super sports car with zero-emission high-tech drive. This model sees Mercedes-Benz and AMG displaying their expertise in the development of alternative drive solutions for high-performance super sports cars, delivering further proof of their pioneering status in this market segment.

The Mercedes-Benz SLS AMGwith electric drive transforms the vision of powerful and locally emission-free super sports cars into reality thanks to an innovative drive system: powerful forwards 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.

Acceleration from zero to 100 km/h in around 4 seconds

When it comes to dynamics, the electrically driven SLS AMGdelivers an unequivocal statement: 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.

"With the SLS AMG with electric drive, we wanted to redefine the super sports car. For us, it is not just about responsibility. We attach just as much importance to excitement and classic AMGperformance," says Volker Mornhinweg, Chief Executive Officer of Mercedes-AMG GmbH.

Optimum weight distribution and low centre of gravity

The purely electric drive system was factored into the equation as early as the concept phase when the new swing-wing model was being developed by Mercedes-Benz and AMG. 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 near the wheels and very low down in the vehicle. The same applies to the modular high-current battery, whose modules are located in front of the firewall, in the centre tunnel and behind the seats. Advantages of this solution include the vehicle's low centre of gravity and the balanced weight distribution - ideal conditions for optimum handling, which the electrically powered SLS AMG shares with its petrol-driven sister model.

Key data at a glance:

Mercedes-Benz SLS AMG with electric drive
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
 

The installation of the drive components required no changes whatsoever to the swing-wing model's aluminium spaceframe body. And there were just as few constraints when it came to maintaining the excellent level of passive safety and high degree of long-distance comfort that are hallmarks of Mercedes cars.

Strategic alliance for fast electrification of the car

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.

Although, truth be told I'd kinda miss my starter whining on my way to school.

Sure this may be some kind of marketing gimick for dumb rich people but i think this kind of thing is nessisary. First off it gives the manufacturers the excuse to dabble with electrical technology. Second this SLS may change peoples mind that hybrid = prius. So to hemi especially, maybe you can put the soundtrack of an engine firing up on your mp3 if you miss it so much.

All the emotion is gone while driving this. Why make a car with 526 hp, if you don't hear it when you fire it up? I think a ford transit would give you a bigger smile on your face, just because how much noise it makes

SHAME ON YOU AMG! Rubbish pice of #$#%$^^$** this is! This isn't a sportscar anymore. This is the worst car from Mercedes EVER. You guys all think it's impressive, but I bet you all would buy the 6.2 V8, even if the costet exactly the same.

Like it or not, I think we're looking at the future of sports cars... Btw, does the regular petrol-driven version of the SLS also have pushrod front suspension as seen on the illustration, or is this only for the electric drive model??

that's damn impressive. i just thought of something, what would happen in the RARE case that this car goes flying over some guard rails into ... say a RIVER lol. would the occupants get electrocuted? will all the fishes die near by? lol just a thought :P
