The Mercedes-AMG GT 4-Door is a confusing proposition. Why would AMG go through the trouble to build a new four-door with a coupe-like profile, when Mercedes already makes the CLS, a four-door with a coupe-like profile? To get to the bottom of this critical mystery, we spoke with AMG boss Tobias Moers at the New York Auto Show. The reason? It's what customers want.To get more latest car news, you can visit shine news official website.
We saw that if C63 and E63 customers were looking for the next level, we didn't have a great offering," Moers told me. "For most of them, a CLS was not the right approach, so we lost some people to other brands."

Moers didn't name any of those "other brands," but it's pretty obvious he's referring to cross-town rival Porsche. The GT 4-Door is very clearly aimed at the Porsche Panamera in that it's a sedan with more aggressive looks, and the promise of sports-car performance.

The AMG GT 4-Door is based on Mercedes' modular sedan platform, using a floorpan similar to that of the E63 Wagon. But don't think of this as just a cynical re-body—the GT 4-Door is significantly different than any other Mercedes sedan.AMG worked hard to make sure the GT 4-Door's body was extra stiff, and there are new subframes front and rear. The rear subframe had to be different because the AMG fit the GT 4-Door with rear-axle steering, technology it introduced to great effect on the GT R.

And in 63 S form, the GT 4-Door offers more power than any other AMG, 630 horsepower from its 4.0-liter twin-turbo V8. It's basically the same engine you get in 577-hp form in the GT R, but the combustion ratio and charge-air cooling have been changed to eke out more power. I asked Moers if we'd see another AMG with this 630-hp V8, and he replied simply, "let's wait.""It's not just a modified CLS," Moers said. "There's an understanding at AMG of how to engineer, how a car feels, how a car should drive—this was done with that car."I suggested that the GT 4-Door might be the ideal AMG sedan because instead of starting with a preexisting car, as with the E63, AMG built this one from the ground up. "It's not far away," Moers said.
