The SL 55 AMG version was released in 2002.
The SL 63 AMG version replaced it in 2008.

The new model has only slight visual differentiators, the most noticeable is the three-slat grille rather than the four-slat version used previously.
The top speed is limited to 250 km/h (155 mph), but can be extended to 300 km/h (186 mph) for an additional cost.
The 6.3 litre V8 replaced the current engine for the 2009 model year.
Upon release in 2002 this was for its time the fastest automatic car in the world.
This was before the SLR Mclaren hit the market in 2003.
Jeremy Clarkson owned one of the very first SL 55 AMG's.

Mercedes engineers claimed that the SL 55 AMG could reach 208 mph if it was derestricted.
