AMG engineers have been hard at work during Europe’s foulest winter in years perfecting Mercedes-Benz’s forthcoming SLS Gullwing supercar.

Affalterbach shoulders an unenviable burden of responsibility with regards to the SLS.

Firstly, it will attempt to usurp Woking’s technical mastery and SLR legacy, and secondly, the SLS – featuring a gullwing door configuration – carries the memory of the 1950s 300SL, arguably one of the greatest cars ever.

SLR production peters out in May this year, thereafter Mercedes-Benz is set to end its partnership with McLaren on a nostalgic note with an 75 unit Stirling Moss commemorative SLR speedster production run which tools out by June.

As with any other AMG product SLS engines will be assembled by hand. Trick intake system takes power above 400kW.

The company’s AMG fettled SLS Gullwing should be its major draw card for the world’s preeminent auto show – Frankfurt – in September. AMG has released images of extreme cold weather testing currently being conducted with SLS prototypes, and revealed some technical details pertaining to the car.

Reworked 6.2l V8

As gleaned form the images, SLS configuration is a traditional, front-engined, rear-wheel drive set-up. Although AMG’s venerable 6.2l V8 nestles snugly under the elongated hood, the engine, and entire drivetrain in fact, has been significantly reengineered.

Producing 420kW and 650Nm, the SLS spec V8 benefits from a new magnesium intake, featuring eight individual velocity stacks, fed by two electronically controlled throttle plates. Dry-sump lubrication has enabled AMG engineers to place the engine as low as possible in the SLS chassis, behind the front axle centre point for optimal weight distribution.

Lighter than the McLaren SLR it replaces by 136kg, with a new DCT gearbox SLS is tailored for keen driving.

Trick gearbox

Transferring drive to the wheels is a seven-speed rear transaxle mounted, automated manual, transmission featuring dual clutch functionality. Receiving drive from a lightweight carbon-fibre composite driveshaft, it’s a world away from standard SL63 AMG…

AMG has been keen to keep the SLS rolling mass as low as possible from the outset, providing as engaging a driving experience as possible. The design team has apparently achieved a target weight 136kg lighter than the SLR, distributing 1 620kg in a 48- to 52% front/rear balance.

Performance claims are in line with the outgoing McLaren car, with the SLS sprinting from 0-100km/h in 3.8 seconds, and topping out around 315km/h.
