An extension of the GT sports car line, Mercedes says the new four-door model is aimed at customers “who are looking for a practical daily ride” but aren’t willing to give up on driving a sports car.

This is far from the first four-door by Benz’s high-po AMG division, but is the first the company feels fits the sports car label. It’s also available with a mild hybrid powertrain that Mercedes completely glosses over in its press release, instead focusing on the uplevel models that make their power exclusively with forced induction and lots of gasoline.

That hybrid setup comes in the GT 53 4Matic model, whose engine bay is home to a 3.0L inline six with both exhaust driven and electric turbochargers and a 48-volt hybrid drive system. On its own, the gas engine makes 429 hp and 384 lb-ft of torque, and the electric motor throws in 21 hp and 184 lb-ft, for totals of 450 hp and 568 lb-ft.

Naturally, that’s not enough to eclipse the performance offered by a pair of 4.0L turbo V8 GT 63 models, the first of which is good for 577 hp and 590 lb-ft, while the 63 S boasts 630 hp and 664 lb-ft.

The GT 53 will do 0-100 km/h in a claimed 4.5 seconds, while the GT 63 and 63 S will do that in 3.4 and 3.2 seconds, respectively, and the S will hit a top speed of 315 km/h.

All three variants feature nine-speed automatic transmissions (though the hybrid’s is slightly different) and Mercedes-Benz’s 4Matic AWD system.

Appearance-wise, it’s hard not to make comparisons with the Porsche Panamera and Audi A7, cars that have set the stage for competitors that combine speed and interior space.
