Look closely, because beneath those taped-over details lies AMG's first supercar developed in-house with parent and partner Mercedes-Benz
. Due for launch in the spring of 2010, this "reinterpretation" of the iconic M-B 300SL Gullwing promises to do its namesake proud by creating "the perfect synthesis of the strengths of the Mercedes-Benz and AMG brands." An aluminum-intensive spaceframe body and various suspension bits aim to keep the car's curb weight around 3,570 pounds while swing-up gullwing doors add a distinctive heritage cue to its sleek profile. Under that long, flowing hood, the SLS AMG will pack a 571-horsepower/6.2-liter naturally aspirated AMG V8. Set back into a front-mid location, it'll be paired with a new rear-mounted dual-clutch AMG transaxle to enhance the car's overall balance. Mercedes claims the SLS AMG will run 0-60 mph in 3.8 seconds and top out at 196 mph while still returning about 18 mpg and be ULEV clean. Rounding out its performance package are a three-stage ESP stability control system, massive carbon-ceramic brakes, and superlight AMG alloy wheels with high-grip performance tires developed specifically for the SLS AMG.
