At a glance
As two of the greatest brand ambassadors for Mercedes-Benz, the Mercedes-AMG SL 63 and the Mercedes-AMG SL 65 combine the engaging driving qualities of a powerful and dynamic coupé with the sybaritic pleasures of roadster motoring. They feature advanced lightweight aluminium-intensive construction, class-leading aerodynamics, a range of highly efficient forced-induction petrol engines and sophisticated driver-assist and safety technologies.
The Mercedes-AMG SL 63 – key figures
The Mercedes-AMG SL 63 is priced at £112,510 and is powered by a 5,461 cc, biturbo V8 petrol engine. Mated to an Mercedes-AMG Speedshift MCT seven-speed transmission, it develops 585 hp at 5,500 rpm and 900 Nm of torque at 2,000-4,500 rpm for a 4.2 second sprint to 62 mph and an electronically limited 155 mph top speed. Combined economy and CO2 emission figures are 28.5 mpg and 229 g/km, helped by the standard fitment of ECO start/stop. It weighs 1,845 kg.
The Mercedes-AMG SL 65 – key figures
The Mercedes-AMG SL 65 is priced at £170,815 and is powered by a 5,980 cc, biturbo V12 petrol engine. Hooked up to an Mercedes-AMG Speedshift Plus 7G-Tronic automatic transmission, it develops 630 hp at 4,800 rpm and 1,000 Nm of torque at 2,300-4,300 rpm for a 4.0 second sprint to 62 mph and an electronically limited 155 mph top speed. Combined economy and CO2 emission figures are 24.4 mpg and 270 g/km, helped by the standard fitment of ECO start/stop. It weighs 1,950 kg.
Externally, the Mercedes-AMG SL 63 is distinguished by its 19-inch Mercedes-AMG five-spoke alloy wheels; Mercedes-AMG bodystyling; chromed twin-louvred grille; Mercedes-AMG sports exhaust system with two chromed twin tailpipes; V8 BITURBO lettering on its front wings; Mercedes-AMG-specific LED daytime driving lights, and a diffuser-style rear apron with body-coloured inserts. To this, the Mercedes-AMG SL 65 adds bespoke chromed twin tailpipes, ‘V12 BITURBO’ badges on the front wings and the front apron’s high gloss chromed cross-bar. The two-bar Mercedes-AMG grille, bonnet and side fins are also finished in high gloss chrome.
Mercedes-AMG cabin class
This visual dynamism is continued inside the Mercedes-AMG SL 63, with its nappa leather-trimmed Mercedes-AMG Performance steering wheel with aluminium gear shift paddles, Mercedes-AMG Drive Unit with E-Select shift lever and Mercedes-AMG instrument panel with Mercedes-AMG start-up screen and Racetimer function for recording lap times. The nappa leather Mercedes-AMG sports seats feature model-specific stitching and are complemented by Mercedes-AMG carbon fibre interior trim, an IWC-designed clock, ambient interior lighting and white backlit Mercedes-AMG door sill panels in brushed stainless steel. In addition, the Mercedes-AMG SL 65 features comfort-ventilated multi-contour seats, a Bang & Olufsen BeoSound Mercedes-AMG surround sound system, and a Black designo leather roof lining.
Mercedes-AMG sports suspension based on Active Body Control
Both AMG models are equipped with an enhanced version of the AMG sports suspension with Active Body Control. For greater agility and higher cornering speeds the suspension features a higher degree of negative camber and fully revised elastokinematics. Exceptionally dynamic characteristics with reduced roll and firm body damping (‘Sport’) or more comfort-orientated settings for a high level of comfort on long journeys (‘Comfort’) can be selected at the push of a button.
Mercedes-AMG SPEEDSHIFT MCT seven-speed sports transmission
The Mercedes-AMG SL 63’s transmission can be adapted to specific requirements, with four modes to select from: ‘C’ (Comfort Efficiency), ‘S’ (Sport), ‘S+’ (Sport plus) and ‘M’ (Manual). An automatic double de-clutching function for downshifting and the RACE START function are also included as standard. The SL 65 AMG is fitted with an AMG Speedshift Plus 7G-Tronic automatic transmission that has been developed to match the V12’s torque characteristics.
Lightweight aluminium construction
The body of the SL-Class is composed of 89 per cent aluminium – a construction layout similar to that of the Mercedes-AMG GT super sports car. The only exceptions are the cover behind the fuel tank, which is made from even lighter magnesium, and the high-strength steel tubing, which supports the A-pillars to ensure total occupant protection in the event of a roll-over accident. Compared with the preceding model, which featured a steel construction, this lightweight construction delivers a significant weight saving of around 110 kg, while also enhances rigidity, safety and comfort.
A roof for all weathers
The electrically-operated fully-automatic folding is available in three formats – the standard vario-roof, the option of the transparent Panoramic vario-roof, and the Panoramic vario-roof featuring the Mercedes-Benz Magic Sky Control system, which allows the light and heat intensity in the cabin to be varied at the touch of a button. The SL-Class also comes as standard with Frontbass®, a unique system of mounting the audio system’s bass speakers in the aluminium structures in front of the footwells, which then become resonance chambers delivering crisp, concert-hall sound even when driving with the roof down.
Superb safety standards
Arguably the world’s safety roadster-coupé, these Mercedes-AMG models feature an ultra-stiff aluminium bodyshell with precisely defined deformation zones and a double-thickness plate floor. In the event of a roll-over, the reinforced steel and aluminium A-pillars and windscreen surround deliver outstanding protection, helped by a pair of pop-up rollover bars housed at the rear of the passenger compartment and Neck-Pro crash-responsive head restraints. Other standard safety features include: Active Bonnet; Adaptive Brake; Attention Assist; Intelligent Light System; ESP® Electronic Stability Programme with ASR Acceleration Skid Control; Magic Vision Control heated adaptive wiper system; six airbags and Pre-Safe® anticipatory safety system.
These Mercedes-AMG models have a length x width x height of 4,617 x 2,099 x 1,315 mm, and a wheelbase of 2,585 mm. Luggage capacity is 504 litres with the roof in place or 364 litres when it is stowed.
