It's not often that a manufacturer has the same name for two completely different cars. Mercedes-AMG did exactly that with the GT. Most of us know the GT as a low-slung, two-door grand tourer but now, the four door version has just been revealed during this year's Geneva Motor Show. Officially, it's called the Mercedes-AMG GT 4-Door Coupe yet the badge on its trunklid says GT 63 (or 53). But enough dwelling on its name, it's time to check out the numbers from the latest AMG hot rod.

There are three engine choices to choose from in the GT 4-Door Coupe. It starts with the AMG GT 53 which uses a turbocharged 3.0-liter inline-six with 435 PS although its torque figure has yet to be announced. The GT 53 is a mild hybrid which adds 21 PS and 250 Nm of torque, as well as promising gains in fuel economy. In the middle is the AMG GT 63's 4.0-liter BiTurbo V8 with 585 PS and 800 Nm of torque.

For those who want even more power, there's the even more potent GT 63S which uses the same V8 as the non-S model but given a healthier dose of horsepower and torque. The top-spec GT 4-Door Coupe makes 639 PS and a staggering 900 Nm of torque.

To reel in all that power, the four-door GTs come standard with all-wheel drive with no rear-wheel drive option. It does, however, come with 'Drift Mode' to effectively make it two-wheel drive. Drift Mode is only available in the V8 models. The GT 53, GT 63 and GT 63S all shift via a nine-speed automatic transmission.

While the GT 4-Door Coupe uses Mercedes-Benz CLS underpinnings, its overall design is unique from the car it was based on. It's faithful to the GT Concept which, co-incidentally, was shown during last year's Geneva Motor Show. There's the slim, upswept LED headlights with the wide Panemerica grill boldly sitting in the center.

Large air dams can be seen at each corner of the front bumper while the grill is similar to that to the two-door sports car. On to its side, it has a coupe-like roof line, just as the automaker had intended. Like the concept, the production model adapts a liftback tailgate while extended fender flares give the car a wide and aggressive stance. Towards the rear, one can see the slim tail LED tail lights, as seen in the preview. It also has a centrally-mounted exhaust pipe and a diffuser at the bottom of the bumper.

Like the exterior, the interior is unique to this model too. Its design is a mix of classic and modern Mercedes-Benz design cues. The circular air-conditioning vents hark back to the 70's, as well as the rounded dashboard fascia. Current styling touches include the electro-mechanical gear selector, the wraparound cockpit and, of course, the wide infotainment screen which merges into the fully digital instrument cluster.
