About the 2003 Mercedes-Benz SL-Class SL600 Brabus T12
The Brabus T12 is a power kit for the R230 SL 600. It keeps the 5.5 liter twin turbo V12. Listings quote 570 horsepower and 663 pound feet of torque. A fan wiki shows 419 kW, or 570 PS, and 900 Nm. That works out to about 562 mechanical horsepower. The stock engine makes about 500. Brabus also offered a 6.3 liter SV12 for the same car. That is a different kit. Collectors like the T12 as a quiet, strong grand tourer. When buying, ask for the Brabus invoice and the Brabus plate. Wheels alone prove nothing. Listings show output claims between 570 and 590 horsepower. Treat the exact figure as a claim.
