New SLS AMG Roadster revealed

These pictures show the new SLS AMG Roaster, Mercedes' drop-top supercar that's set to go on sale in the autumn.

Mercedes says these photos are 'slightly disguised', however we will see the car in the metal at the Frankfurt motor show in September.

The Roadster forgoes the coupe's gullwing doors, so that it can accommodate the soft-top roof, which opens and closes in 11 seconds at speeds of up to 30mph.

Underneath the bonnet is the 563bhp hand-assembled AMG engine from the coupe. Like the hard-top car, the Roadster has a limited top speed of 197mph.

While prices have yet to be revealed, expect the car to cost around 180,000.
