The SV12 S Biturbo engine swap appears to have been created by someone with a severe, pathological hatred for tires. This is the same engine used in the Brabus Bullit, and it dishes out a predictably ridiculous 720 horsepower and 973 lb-ft of torque. The latter number is electronically restrained to a mere 811 lb-ft., and a top speed of well over 200 mph comes with the territory. Not interested in the full swap? No worries, BRABUS has your back. SL 65 AMG drivers can opt for the T 65 S package, which bumps the stock V12 Biturbo to 705 hp/811 lb-ft. There's a solution for the all-motor SL 63 AMG as well that packs on an additional 40 horses over stock. This pattern continues right on down the line -- even the "lowly" V6-powered cars can be tuned to deliver 327 hp/ 310 lb-ft. Bonkers. Er, BRABUS, rather.
