However, the most significant changes are under the hood starting off with the naturally aspirated 6.3L V8 engine that generates 525 HP and 630 Nm of torque (SL 55 AMG: 5.5-liter supercharged V8 with 517 HP and 720 Nm). According to Mercedes-Benz, the new SL 63 AMG sprints from zero to 100 km/h (62 mph) in 4,7 sec or 0,2 sec slower than the outgoing SL 55 AMG. -Continued
The V8 engine unit is combined with a new MCT 7-speed sports transmission that's apparently quicker than the standard 7-speed G-Tronic. Additionally, the 2009 SL 63 AMG also gets a new sports suspension and a new speed sensitive steering wheel system. Finally, there's also a new 3-stage ESP system (ON/SPORT/OFF).
