While Mercedes-AMG continues to tease the upcoming GT4, the car appears to have been leaked.



The low-resolution picture, brought to our attention by CarScoops reader Eric, reveals the obvious: a Panamericana grille at the front, muscular lines all around, a sloping roofline, and a rear wing.

Its dynamic design, meant to differentiate it from the new generation CLS and serve as a more upscale and aggressive-looking replacement for the old AMG CLS 63, is wrapped in a four-door coupe body style.

When it goes on sale, likely later this year, it will challenge the upcoming BMW M8 Gran Coupe, which is said to be previewed by a concept in Geneva. It will also serve as a rival to the anticipated Audi RS7 Sportback, and the top-end Porsche Panamera as well.

Despite the numerous spy shots and reports surrounding the new Mercedes-AMG GT4, we still don’t know the engine specifications.

Some speak about the 4.0-liter twin-turbo V8 engine, which makes up to 603 horsepower in the new AMG E63 S, while others believe that it will get an electric motor as well, just like the AMG GT study shown last year.

If the latter scenario turns out to be true, then the executive four-door coupe will probably have in excess than 800 horsepower. Moreover, such a model would challenge the likes of the Porsche Panamera Turbo S E-Hybrid, which has ‘only‘ 671hp available on tap.

Luckily, we won’t have to wait long to find out as the AMG GT4 (or whatever Mercedes calls it) will be revealed at the 2018 Geneva Motor Show on Tuesday.
