2003 Mercedes SL Launched wearing MB's old faithful 5.0-litre V8, the R230 eventually fell into AMG's hands in 2002. It added a bloody great big supercharger and increased displacement to 5.5-litres, which got it from 0-62mph in 4.7 seconds. But that wasn't quite enough. In 2005, AMG fitted a twin-turbo 36-valve V12, which made 1057Nm of torque. ONE THOUSAND FIFTY SEVEN. Its 0-100mph time was also whittled down to 4.2 seconds.
