The Swiss tuners at FAB Design have pulled back the sheets to reveal the modified Mercedes SLS AMG. Although the tuning company was scarce on the details, we do know that they were able to gain an extra 40 horsepower from the Gullwing door supercar. This comes from the Mercedes V8 engine producing a total of 611 hp after the tuning. At the track it improved the sprint time from 0 to 100 km/h in 3.7 seconds, a .1 difference from the factory car time. FAB Design also designed a new body kit for the SLS AMG, consisting of a re-styled front bumper with new vents and a lip spoiler, side skirts, roof scoop, and a new rear bumper that accompanies the four exhaust tips.
