Mercedes AMG just teased an intriguing version of its fastest road car

AMG, Mercedes' in-house tuning department, teased on Wednesday a sportier version of its flagship grand tourer, the AMG GT and AMG GT S.

The new AMG GT R appears in a YouTube video that calls the car a "beast of the Green Hell," referring to the nickname of the Nürburgring, the infamous German racetrack at which the AMG GT's racing cousin, the AMG GT3, just captured the four top places in a 24 hour race last month.

The upcoming road car, which includes a very large, carbon fiber wing, is likely to be the most hardcore version yet. It may include an upgrade to the healthy 503 horsepower bi-turbo V8 engine offered in the AMG GT S, as well as some weight saving measures and upgrades to the suspension and brakes.

The car will make its public debut at the Goodwood Festival of Speed in the United Kingdom on June 24th.
