Mercedes-Benz SLS AMG Coup� Electric Drive:
Electrifying - the world's most powerful electric super sports car

With the new SLS AMG Coup� Electric Drive, Mercedes-AMG is entering a new era: the locally emission-free super sports car featuring advanced technology from the world of Formula 1 is the most exclusive and dynamic way in which to drive an electric car. The most powerful AMG high-performance vehicle of all time has four electric motors producing a total output of 552 kW and a maximum torque of 1000 Nm. As a result, the gullwing model has become the world's fastest electrically-powered series production vehicle: the SLS AMG Coup� Electric Drive accelerates from zero to 100 km/h in 3.9 seconds.

A new dimension of driving performance � a convincing synonym for the AMG brand promise are the outstanding driving dynamics which come courtesy of AMG Torque Dynamics as well as torque distribution to individual wheels, which is made possible by means of wheel-selective all-wheel drive. The most "electrifying" gullwing model ever has been developed in-house by Mercedes-AMG GmbH. The high-voltage battery for the SLS AMG Coup� Electric Drive is the result of cooperation between Mercedes-AMG and Mercedes AMG High Performance Powertrains in Brixworth (GB). This is an area in which the British Formula 1 experts were able to contribute their extensive know-how with KERS hybrid concepts.

"The SLS AMG Coup� Electric Drive is setting new standards for cars with electric drives. As the most powerful gullwing model ever, it is also representative of the enduring innovational strength of Mercedes-AMG. Our vision of the most dynamic electric vehicle has become a reality. With the help of our colleagues at Mercedes AMG High Performance Powertrains in Brixworth, we are bringing exciting advanced technology from the world of Formula 1 to the road", according to Ola K�llenius, Chairman of the Board of Management of Mercedes-AMG GmbH.

Pioneering, visionary, electrifying: the powerful and locally emission-free super sports car with electric drive also embodies the development competence of Mercedes-AMG GmbH. With this innovative and unique drive solution, AMG - as the performance brand of Mercedes-Benz - is demonstrating its technological leadership in this segment. The SLS AMG Coup� Electric Drive is aimed at technology-minded super sports car fans who are open to new ideas and enthusiastic about ambitious high-tech solutions for the future of motoring.

Enormous thrust thanks to 1000 Nm of torque

The pioneering drive package in the SLS AMG Coup� Electric Drive is impressive and guarantees a completely innovative and electrifying driving experience: enormous thrust comes courtesy of four synchronous electric motors providing a combined maximum output of 552 kW and maximum torque of 1000 Nm. The very special gullwing model accelerates from zero to 100 km/h in 3.9 seconds, and can reach a top speed of 250 km/h (electronically limited). The agile response to accelerator pedal input and the linear power output provide pure excitement: unlike with a combustion engine, the build-up of torque is instantaneous with electric motors � maximum torque is effectively available from a standstill. The spontaneous build-up of torque and the forceful power delivery without any interruption of tractive power are combined with completely vibration-free engine running characteristics.

The four compact permanent-magnet synchronous electric motors, each weighing 45 kg, achieve a maximum individual speed of 13,000 rpm and in each case drive the 4 wheels selectively via a axially-arranged transmission design. This enables the unique distribution of torque to individual wheels, which would normally only be possible with wheel hub motors which have the disadvantage of generating considerable unsprung masses.

Powerful, voluminous, dynamic, emotional and authentic: the characteristic sound of the SLS AMG Coup� Electric Drive embodies the sound of the 21st century. After an elaborate series of tests as well as numerous test drives, the AMG experts have created a sound which captures the exceptional dynamism of this unique super sports car with electric drive. Starting with a characteristic start-up sound, which rings out on pressing the "Power" button on the AMG DRIVE UNIT, the occupants can experience a tailor-made driving sound for each driving situation: incredibly dynamic when accelerating, subdued when cruising and as equally characteristic during recuperation. The sound is not only dependent on road speed, engine speed and load conditions, but also reflects the driving situation and the vehicle's operating state with a suitable driving noise. Perfect feedback for the driver is guaranteed thanks to a combination of the composed sound, the use of the vehicle's existing inherent noises and the elimination of background noise � this is referred to by the experts as "sound cleaning". The impressive sound comes courtesy of the standard sound system with eleven loudspeakers.

Advanced Formula 1 technology: high-voltage lithium-ion battery

Battery efficiency, performance and weight: in all three areas Mercedes-AMG is setting new standards. The high-voltage battery in the SLS AMG Coup� Electric Drive boasts an energy content of 60 kWh, an electric load potential of 600 kW and weighs 548 kg � all of which are absolute best values in the automotive sector. The liquid-cooled lithium-ion high-voltage battery features a modular design and a maximum voltage of 400 V.

Advanced technology and know-how from the world of Formula 1 have been called on during both the development and production stages: the battery is the first result of the cooperation between Mercedes-AMG GmbH in Affalterbach and Mercedes AMG High Performance Powertrains Ltd. Headquartered in Brixworth in England, the company has been working closely with Mercedes-AMG for a number of years. F1 engine experts have benefited from its extensive expertise with the KERS hybrid concept, which made its debut in the 2009 Formula 1 season. At the Hungarian Grand Prix in 2009, Lewis Hamilton achieved the first historic victory for a Formula 1 vehicle featuring KERS hybrid technology in the form of the Mercedes-Benz KER System. Mercedes AMG High Performance Powertrains supplies the Formula 1 teams MERCEDES AMG PETRONAS, Vodafone McLaren Mercedes and Sahara Force India with Mercedes V8 engines and the KERS.

The high-voltage battery consists of 12 modules each comprising 72 lithium-ion cells. This optimised arrangement of a total of 864 cells has benefits not only in terms of best use of the installation space, but also in terms of performance. One technical feature is the intelligent parallel circuit of the individual battery modules � this helps to maximise the safety, reliability and service life of the battery. As in Formula 1, the battery is charged by means of targeted recuperation during deceleration whilst the car is being driven.

High-performance control as well as effective cooling of all components

A high-performance electronic control system converts the direct current from the high-voltage battery into the 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 optimum operating temperature with the aid of an electric heating element. In extremely high external temperatures, the cooling circuit for the battery can be additionally boosted with the aid of the air conditioning. This also helps to preserve the overall service life of the battery system.

Quick charge function via special wall box

Ideally the SLS AMG Coup� Electric Drive is charged with the aid of a so-called wall box. Installed in a home garage, this technology provides a 22 kW quick-charge function, which is the same as the charging performance available at a public charging station. A high-voltage power cable is used to connect the vehicle to the wall box, and enables charging to take place in around three hours. Without the wall box, charging takes around 20 hours. The wall box is provided as an optional extra from Mercedes-AMG in cooperation with SPX and KEBA, two suppliers of innovative electric charging infrastructures for the automotive industry.

Eight-stage design for maximum safety

To ensure maximum safety, the SLS AMG Coup� Electric Drive makes use of an eight-stage safety design. This comprises the following features:
1. all high-voltage cables are colour-coded in orange to prevent confusion
2. comprehensive contact protection for the entire high-voltage system
3. the lithium-ion battery is liquid-cooled and accommodated in a high-strength aluminium housing within the carbon-fibre zero-intrusion cell
4. conductive separation of the high-voltage and low-voltage networks within the vehicle and integration of an interlock switch
5. active and passive discharging of the high-voltage system when the ignition is switched to "off"
6. in the event of an accident, the high-voltage system is switched off within fractions of a second
7. continuous monitoring of the high-voltage system for short circuits with potential compensation and insulation monitors
8. redundant monitoring function for the all-wheel drive system with torque control for individual wheels, via several control units using a variety of software

By using this design, Mercedes-AMG ensures maximum safety during production of the vehicle and also during maintenance and repair work. Of course the SLS AMG Coup� Electric Drive also meets all of the statutory and internal Mercedes crash test requirements.
