Mercedes has caused history to repeat itself as they have come out with a roadster version for one of their popular coupes. This trend was seen in the SLR McLaren and will now repeat itself with the SLS AMG coupe version. The SLS AMG Roadster will be revealed in September at the Frankfurt Motor Show, but right now the car is under extreme testings.

The Mercedes SLS AMG roadster version will be powered by a 6.3-liter V8 engine with 563 hp and 479 lb-ft of torque. However, being a much heavier model, it will rocket from 0 to 60mph in 4.0 seconds before topping out at approximately 192 mph.

Like with the coupe version, the roadster version will feature a long bonnet, large wheels, and a short rear end. Both coupe and roadster versions are also built on an aluminum spaceframe, but due to the omission of a fixed roof and gullwing doors for the roadster, it was necessary to design the side sills more robustly.

The new Mercedes SLS AMG Roadster will be offered with a three-layered fabric soft top which is deposited behind the seats in a Z-formation to save space. The sports car offers a low center of gravity and is designed for speeds up to 196 mph.

Under the hood, the Mercedes SLS AMG Roadster  will feature the same engine as the coupe: a 6.3-liter V8 engine located front-mid that will develop 571 hp and up to 479 lb-ft. of torque. The engine will be mated to a seven-speed dual-clutch transmission. Mercedes has also announced that the roadster will be capable of a top speed that is just one mph lower than the coupe: 196 mph.
