Mercedes-Benz kept the SLR McLaren around for a solid eight years. The SLS AMG hasn't even been around for five, but already Benz is preparing to roll out its next sports car. We've been anticipating the arrival of the new Mercedes-AMG GT for some time now, but now we've got the exact date of its debut.

This latest video gives us plenty of figures to chew on, from the amount of camouflage sheets used to wrap the prototypes to the temperatures at which they were tested. But the salient detail is that the coupe – which is expected to cost less than its SLS forbearer – will officially be unveiled on September 9.

Expect a public debut to follow at the Paris Motor Show the following month, after which its new 4.0-liter twin-turbo V8 will be available in two states of tune: 462 horsepower or 510, nestling comfortably in between the V8 and V10 versions of the Audi R8 and just a few steps behind the Porsche 911 GT3 and Turbo.
