The new SL 63 SE Performance is the pinnacle of Mercedes-AMG’s SL series, whose 4.0-litre V8 biturbo engine and Electric Drive Unit together generate a system output of 600 kW (816 hp) and a maximum system torque of up to 1,420 Nm. This makes the new model the most powerful SL of all time.
The word ‘Performance’ in the new SL badge indicates the fact that it is the fifth model to feature the AMG-specific E Performance hybrid technology. The immediate response of the electric drive, the rapid build-up of torque and the linear power delivery enable an impressive driving experience.
The acceleration to 100 kmph in 2.9 seconds and the top speed of 317 kmph underline the car’s confident appearance. Systems such as the AMG Active Ride Control suspension with active roll stabilisation and active rear-axle steering deliver comfort as well as driving dynamics.
Michael Schiebe, CEO of Mercedes-AMG GmbH, comments: “The SL has always been an icon in the Mercedes-Benz portfolio. The latest version of the legendary roadster transfers this status into the future. First and foremost is the new SL 63 S E Performance, which, with its innovative technology, is the most powerful member of the SL family.
“With this unique concept, we offer our customers not only superior Performance but also the option of all-electric driving. Extensive equipment options and the high-quality materials used also make the SL one of the most exclusive roadsters on the market – a real dream car.”
In the SL Performance, the AMG 4.0-litre V8 biturbo engine on the front axle combines with the electric drive unit on the rear axle. It integrates a 150 kW (204 hp), permanently excited synchronous electric motor with an electrically switched two-speed transmission and a mechanical rear-axle limited-slip differential. The lightweight high-performance battery is also located in the rear above the rear axle.
This compact design results in numerous advantages. The electric motor acts directly on the rear axle and can therefore convert its power more directly into propulsion. This provides an extra boost when starting, accelerating, or overtaking. As the slip on the rear axle increases, the driving force of the electric motor is also transferred to the front wheels as required.
The mechanical connection of the fully variable AMG Performance 4MATIC+ all-wheel drive makes this possible via the cardan shaft and drive shafts of the front wheels. The positioning on the rear axle improves the weight and axle load distribution in the vehicle and thus forms the basis for convincing handling.
The development of the lithium-ion energy storage is inspired by technologies proven in the marque’s Formula 1 hybrid racing cars. The high-performance battery offers a capacity of 6.1 kWh, 70 kW continuous power, 150 kW peak power and 13 km of purely electric travel. It is designed for fast power delivery and consumption and not for the longest possible range. Therefore, maximum propulsion is always available when the driver needs it – for example, to be able to accelerate powerfully out of corners or when overtaking.
Because the high-performance battery is always in the optimal temperature window of around 45 degrees thanks to its direct cooling, recuperation can also be optimised. The driver can select four different levels of recuperation power in all but one of the eight driving programs. At the highest level “one-pedal” driving is possible as over 100 kW of power can be fed back into the battery. Another advantage of recuperation is that the vehicle can maintain its speed when going downhill as the system works like an engine brake.
The distinguishing feature of the new top model in the SL series is the rear section. The integrated plug-in loading flap and the “E PERFORMANCE” fender badge are highlighted in red. There are also grooved trapezoidal twin tailpipe trims on the outside. As standard, the hybrid rolls on 20-inch multi-spoke AMG light-alloy wheels. They are aerodynamically optimised, painted matt black with a high-sheen finish.
As with the entire series, numerous paints and individual equipment details are also available for the hybrid version. The Manufaktur programme with an extensive selection of exterior and interior customisation is also available, with the colour orange flame being a new and exclusive offer. The exterior design can be further accentuated with numerous appearance packages, among other things. There are also 20- and 21-inch light alloy and forged wheels in various colour variants.
The interior serves the sporty target group as well as customers who value maximum comfort. The cockpit design right down to the portrait format display in the centre console is focused on the driver and impresses with a harmonious overall impression. The practical dimensional concept with 2+2 seats offers generous space in the interior.
One of the highlights of the interior is the electrically adjustable AMG sports seats. They combine good lateral support with long-distance comfort. The optional AMG performance seats with integrated headrests and ventilation openings in the seat backs are even sportier. The seats offer three massage programmes. The Energizing Package Plus combines seating functions and lighting moods to create relaxing comfort programs.
The large selection of seat covers ranges from comfortable to performance-oriented selections. One- and two-tone Nappa leather is included, as is the particularly elegant Manufaktur upholstery in Nappa leather with diamond quilting. The sporty side is emphasised by the combination of Nappa leather with Microcut microfibre and contrasting topstitching in yellow or red.
Although the new SL 63 SE Performance is the pinnacle of Mercedes-AMG’s SL series in terms of performance, it has not compromised on its core DNA, that of an exceptional grand tourer. While the performance on the road is outstanding, its interior, as is the epitome of luxury.
