Mercedes-Benz AMG SL 63

2026 MERCEDES-AMG SL 63 4MATIC+ BRABUS 750 CARBON EDITION - UK SPECIFICATION

Engine and Drivetrain

The car uses the Mercedes-AMG M177 4.0-litre twin-turbocharged V8 petrol engine, displacing 3,982 cc with the turbochargers mounted inside the cylinder-bank vee, direct petrol injection and a compression ratio of 8.6:1. In standard AMG SL 63 4MATIC+ form it produces 585 PS and 800 Nm. This unit carries the BRABUS PowerXtra B40S-750 conversion, which raises output to 750 PS and peak torque to 900 Nm through remapped engine management, the BRABUS BoostXtra valve and a BRABUS valve-controlled high-performance sports exhaust system with sport-design tail pipes. Drive goes through the AMG SPEEDSHIFT MCT 9-speed automatic transmission with a wet start-off clutch to AMG Performance 4MATIC+ fully variable all-wheel drive with an electronically controlled rear limited-slip differential. BRABUS quotes 0-100 km/h in 3.3 seconds against 3.6 seconds for the standard car, with top speed unchanged at approximately 315 km/h.

Chassis, Steering and Brakes

The R232 SL uses an aluminium composite spaceframe with a front double-wishbone and rear multi-link axle, here fitted with BRABUS height-adjustable suspension in place of the standard AMG RIDE CONTROL setup. Rear-axle steering is fitted, turning the rear wheels against the fronts at low speed and with them at high speed. The AMG High Performance ceramic composite braking system is fitted, with BRABUS-branded calipers. A front axle lift system raises the nose to clear kerbs and ramps.

Dimensions and Capacities

Overall length is 4,705 mm, width 1,915 mm excluding mirrors and height 1,359 mm, on a 2,700 mm wheelbase. Kerb weight is approximately 1,970 kg before the BRABUS conversion components. Boot capacity is 213 litres with the roof stowed. The car is a strict two-seater in this configuration.

Exterior

The body is finished in black and carries the full BRABUS carbon aerodynamics package: front splitter, front bumper attachments, illuminated carbon grille inserts, fender attachments, rear diffuser with sport-design tail pipes and rear spoiler. Wheels are the BRABUS Monoblock ZM Platinum Edition forged alloys in gloss black with diamond-cut faces. The extended AMG Night package darkens the remaining exterior brightwork. Lighting is the LED Intelligent Light System with Adaptive Highbeam Assist Plus. The roof is a three-layer electrically operated fabric soft top that opens and closes on the move at low speed.

Interior and Seating

The cabin is trimmed in Nappa leather with AMG performance front seats that are climatised and offer a massage function, a memory package, AMG carbon fibre and piano black trim, and ambient lighting. AIRSCARF neck-level heating extends open-top use into cold weather. BRABUS additions inside are the illuminated entrance panels, matt anodised pedal pads and BRABUS badging package.

Infotainment and Connectivity

MBUX runs on a central portrait touchscreen that tilts electrically to suppress glare with the roof down, paired with a digital instrument cluster and a head-up display. Audio is the Burmester surround sound system. Smartphone integration, wireless charging, DAB digital radio and AMG TRACK PACE telemetry are included.

Driver Assistance and Safety

Driver assistance covers Active Brake Assist, Active Distance Assist, Blind Spot Assist, Attention Assist and the PRE-SAFE anticipatory occupant protection system, alongside a 360-degree camera and parking assistance. Passive protection includes front, front-side and centre airbags, window bags, automatic roll-over protection bars that deploy behind the seats, seat belt pretensioners with force limiters and an active bonnet for pedestrian protection. As a low-volume roadster the model has not been independently crash tested by Euro NCAP.

Performance

Standard AMG SL 63 4MATIC+ performance is 3.6 seconds to 100 km/h and 315 km/h. With the BRABUS PowerXtra B40S-750 conversion BRABUS quotes 3.3 seconds to 100 km/h at an unchanged top speed. CO2 and fuel consumption figures for the converted car have not been homologated and are therefore not stated.
