Boys and girls, welcome to the meanest, greenest AMG. It is the new Mercedes-AMG GT R, the hardest cored, most track-focused version of the GT sports car yet.Its tech specs are detailed but exciting, so bear with us as we take you on a whistle-stop tour of perhaps the most laser-guided attack on the Porsche 911 GT3 RS yet.As an AMG, the only place to start is under the engine bay. Specifically, behind the front axle, where a modified version of the AMG GT"s hot inside V" 4-litre twin-turbo V8 sits. With sharper-reacting turbos and a new exhaust system, it produces 577bhp and 516lb ft, increases of 74bhp and 37lb ft over the next most potent AMG GT, the GT S.The GT R is lighter than the S, too an impressive boast we"ll get to later its 1,630kg combining with the boisterous power output to yield a 3.6sec 0-62mph time and 198mph top speed. That means a 0.2sec cut and 5mph rise over that GT S. Those figures put it on par with the (notably more powerful) SLS AMG Black Series, perhaps its spiritual ancestor.But numbers don"t tell half of the GT R"s story. What will matter to those taking it on track is the pedigree of its chassis componentry. "It combines the driving dynamics of our AMG GT3 racing car with the everyday practicality of the AMG GT"," promises AMG chief Tobias Moers. And there"s certainly a lot of motorsport kudos to the bits his team have fitted to the GT R.Broader track widths and cup tyres are a given. The lightweight, forged aluminium suspension is manually adjustable if you"re handy with the spanners, and has electronic, adaptive damping control if you"re not.You need your pulse testing if you don"t want to take this on trackThere"s an electronic differential operating on the rear axle to help control all those rampant horses. The stability control has three settings (including OFF, if you"re brave/talented/loopy) while the traction control has nine levels of intervention, adjusted via a racing car-like knob in the middle of the dashboard.If you"re a fan of ALL OF THE TRACTION, though, then you"ll be happy to learn about the GT R"s four-wheel steering system. It operates by wire, rather than mechanically, and it can turn the rear wheels by as much as 1.5 degrees.Just like the 911 GT3 (and other Porsches since), it"s a system that aids agility at low speed (well, below 62mph) by turning the rear wheels in the opposite direction to the fronts, and stability at higher speeds, the rears pointing in the same direction as the fronts. The system in the Ferrari F12 tdf only uses the latter approach.You"ll have noticed the bodykit. AMG promises us that form always follows function, and everything from the wide, air-gulping mouth to the manually adjustable rear wing all aid air flow through the car. Don"t half make it look mean too, mind.There are active flaps behind the front fascia and underneath the car, developed on a computer simulation before entering a wind tunnel, and finally being honed on the N rburgring. It is that track which the car"s AMG green hell magno" matt paint pays homage to.
