Mercedes-Benz has announced another introduction to its roadster range, and the SL 63 AMG rolls in to join the SLS AMG Roadster and SLK 55 AMG in the company’s top tier topless range.

The car is available with two power outputs for the first time – the M157 5.5 litre V8 twin-turbo AMG mill offers 537 hp and 800 Nm of torque in its base guise, while with the AMG Performance package strapped on, the figures rise to 564 hp and 900 Nm. And going the all-aluminium bodyshell route means that this one is 125 kg lighter than the car it replaces.

The base output is good enough to get the vehicle from 0 to 100 km/h in 4.3 seconds, and it’s just a shade faster at 4.2 seconds for the AMG Performance spec. Meanwhile, top speed is an electronically-limited 250 km/h, but the AMG Performance package takes this to 300 km/h, again electronically-limited.

Kit incudes an enhanced AMG sports suspension based on Active Body Control (ABC), a new AMG speed-sensitive sports steering, the AMG high-performance compound brake system and the AMG Speedshift MCT 7-speed sports transmission. An automatic double-declutching function for downshifting and the Racestart function are also included as standard with the transmission.

The car comes fitted with five-twin-spoke AMG light-alloy wheels painted titanium grey, with a high-sheen finish, shod with 255/35 front and 285/30 rear tyres. A multi-spoke AMG forged wheel from the AMG Performance Studio is available as an option, and this one is in matte black with a rim flange done in a high-sheen finish.

The sixth-generation SL retains the space-saving, electrohydraulically retractable vario-roof, enabling the SL to be transformed into a roadster or a coupé in under 20 seconds. In contrast to the outgoing model, however, there are three versions to choose from for the new SL, these being painted roof, glass roof or the unique panoramic vario-roof with Magic Sky Control.

Inside, the SL 63 AMG’s cabin gets cues inspired by the SLS AMG – the four jet engine-styled air vents, the E-SELECT lever and the AMG Drive Unit are all reminiscent of the super sports car.

Standard equipment includes AMG sports seats in single-tone or two-tone nappa leather, with a unique V8 seat upholstery layout and AMG badges in the seat backrests, AMG carbon-fibre trim and AMG illuminated door sill panels as well as IWC-design analogue clock.
