The fifth generation of the SL had few AMG special products in its lineup.
Before the mid-life cycle facelift had a supercharged 5.4 V8 unit, which was replaced in 2008 with the bigger 6.2-liter V8 unit. For some, it sound like a downgrade, but the new, naturally aspirated engine, was rev-happy. The SL 63 AMG wasn’t slow at all. The 525 hp and the 630 Nm (465 lb-ft) of torque are good values. It had a new, 7-speed Automatic AMG Speedshift (dual-clutch), compared with the 5-speed automatic gearbox from the SL 55. But the fact is that the new SL63 was slower with 0.1 seconds in the 0-100 kph (0-62 mph) sprint than the model it replaced.

The SL 63 AMG braking system is matching the engine performance. The front wheels are equipped with internally ventilated, perforated 360 x 36-mm composite disc brakes with six-piston aluminum callipers, while at the rear comes from internally ventilated, perforated 330 x 26-mm brake discs with four-piston fixed callipers.

On the exterior, the new front grille evokes the first SL, from 1955, with a horizontal chromed line and the big, three-star badge in the middle. The retractable hardtop (marketed as Vario Roof) was featured on the vehicle.

The standard specification also includes nappa upholstery, carbon-fibre trim and AMG sports seats. The optional AIRSCARF neck-level heating system is a new addition. For entertainment, the SL 63 AMG featured NTG 2.5 telematics system.
