Premium carmaker Mercedes-Benz has just unveiled the new Mercedes AMG GT supercar ahead of its planned public debut at the Paris motor show in October.

This is serious material for any enthusiast’s appetite as the automaker used the iconic Porsche 911 Turbo as a performance benchmark.

“With the new GT, we are positioning Mercedes-AMG even more aggressively than to date, ” said the CEO of AMG, Tobias Moers.

It is carrying the new M178 engine performance engine, a twin-turbocharged 4.0-litre V8 engine that is capable to produce 462 PS (340 kW) in the base model and over 500 (510 PS (375 kW)) in the top of the line AMG GT-S variant. According to Daimler, this new engine will be a replacement for the previous 6.2-liter V8 engine used by the Mercedes SLS AMG, called the M159.

What’s interesting is the somehow Mercedes will start to deliver only the GT-S variant – with base model to follow later. The two are set apart visually by different bumpers, tailpipes and wheels.
This is only the second supercar to be developed in-house by AMG after the SLS AMG – but you shouldn’t consider this as a direct successor of the SLS model. This is smaller, lighter (some 145kg less than the SLS) and cheaper – and is intended to fight with the iconic 911 Turbo and some variants of the new Jaguar F-Type.

The top AMG GT-S model will be capable to hit 100 km/h in just 3.8 seconds (the 911 Turbo hits that speed in 3.4 seconds) and a top speed of 310 km/h (192 mph), while the “normal” model if we can call it like this will get to that speed in 4.0 seconds. Power will be delivered to the rear axle thru a revised seven-speed dual-clutch gearbox. The gearbox will be able to offer both manual and automatic shifting – while the weight distribution will be 47 percent front, 53 percent rear.

All in all you should expect about a fuel efficiency of 30.4mpg for the GT and 30.1mpg for the GT S – with average CO2 emissions of 216g/km and 219g/km respectively.
Based on a predominantly aluminium structure – the Germans are saying that the new supercar will have insane acceleration and go-kart handling. No more gullwing-style doors… why? Because they are too heavy. In standard GT guise, it tips the scales at 1540kg and the GT S comes in at 1570kg.

The GT gets 19-inch wheels with 255/35 front and 295/35 rear tyres while the GT-S will receive 20-inch wheels on the back with 295/30 sporty tyres (you can chose for Michelin Pilot Sport Cup 2 tyres as part of the AMG Dynamic Plus package).
Some “standard” 360mm front and rear rotors will keep braking distance at low levels; while the GT-S will get 390mm disk brakes. Of course buyers will be able to choose carbon-ceramic discs.

Inside, the new model is sharing multiple elements with some of the actual Mercedes vehicles, with the latest edition of Mercedes’s Command connected to a touch-sensitive controller mounted on the centre console. The display is positioned for “minimal driving distraction,” the company said.

The vehicle will include standard safety features seen on the S-Class like collision prevention systems, adaptive brakes, a parking assist system and a rear-view camera.
There will be no roadster variant according to the Germans.

The company didn’t offered yet any information about its price – but we expect that will start somewhere at 120,000 Euro. The GT S won’t be released until the spring of 2015.
