The successor to the Mercedes Benz SL Gullwing (and replacement for the SLR) has been spotted in prototype form in and around Germany’s Nurburgring test circuit for several months now, but what only a select few knew is that the car is being developed completely in-house by Mercedes’ official tuner, AMG. Thus, the brand new model will be called the SLS AMG when it hits showrooms in the first half of next year.
In the lead up to its final unveiling, planned for later this year, Mercedes has released a ton of info on the car, including several images of actual prototypes and technical drawings. As the successor to the legendary SL Gullwing from the 1950s, the new SLS AMG will also feature gullwing doors but picks up a new aluminum spaceframe to provide an almost perfect front-to-rear weight distribution of 48-to-52%.
Powering the SLS will be a revised version of AMG’s now-familiar 6.2L V8 mated to an all-new 7-speed dual-clutch transmission mounted on the rear axle. Peak output will stand at 571hp (420kW) and 479lb-ft (650Nm) of torque. Changes to the engine include a new magnesium intake with eight separate velocity stacks, two electronically controlled throttle plates, a high-flow exhaust and a new dry-sump lubrication system.
