It was back in September when we last saw Mercedes-AMG testing the upcoming GT4. Set to take on the likes of the Audi S7/RS7, BMW 6 Series Gran Coupe and Porsche Panamera Turbo, the GT4 will feature a coupe-like design along with a large hatchback that makes it have a unique profile. It will also come with what appears to be a fully-digital instrument panel and infotainment system.
Now despite the cold winter over in Europe, our eagle-eyed spies were able to catch the GT4 anew being tested in the snow.
Based on the pictures provided, not much has changed on the camouflaged GT4. It still has the signature Panamericana front grill, tapered headlights, sloping roofline, quad exhausts and thin taillights. Like the new E-Class, the GT4 is expected to be underpinned by the same MRA platform. Mechanically-speaking, the new GT4 will be closely similar to the E-Class but will have a wider track, lower body and a different roofline.
Power will reportedly come from a 4.0-liter bi-turbo V8 that will generate 600 PS. With the new E63 also producing 600 PS, it comes to no surprise that the GT4 will have the same output figure. Apart from that, a high-output hybrid version is also expected to make the cut. However, we are not sure if it will have the same output as the concept version which comes with 800 PS.
Entry-level and mid-range models could come with six-cylinder engines as well as a detuned hybrid powertrain. Output figures are expected to be in the range of 400 PS or slightly more.
The Mercedes-AMG GT4 could make its world debut in early 2018, most likely at the Geneva International Motor Show.
