</p><p>Mercedes has taken the wraps off the hard core variant of its AMG GT coupe. The stock version won many hearts among the enthusiasts, ranging from the enthralling sound to a very strong performance. Well, AMG GT R takes the game even further. Not only is the engine more powerful, any excess weight was shaved off to reduce the kerb weight. Apart from acceleration, this reduction in weight means that the car is more agile. Total reduction in weight is 90 kg while the gain in power is 72 BHP, torque also increases by 49 Nm. Physics at play, the increase in power and reduction in weight has resulted in 0-96 KMPH acceleration timings slimming down to 3.5 seconds a reduction of 0.2 seconds over the S Variant. Top speed now stands at 318 kmph, an increase of 9 KMPH. The twin turbo V8 produces 456 BHP in standard variant of GT, the more powerful S variant adds 47 BHP while GT R version further adds 77 BHP to take the figure at 577 BHP i.e. 121 BHP more than standard variant. It's a massive gain by any stretch of imagination factoring in that its an output from essentially the same engine. The final output figures are: 577 BHP@6250 RPM and 700 Nm of torque at 5500 rpm.</p><p>Transmission duty is handled by 7 speed dual clutch transmission which power the rear axle, but the gearbox has been optimized considering the newer application. To increase acceleration in top gear, the last ratio is a shorter one, while the first one is made longer. There are several changes to exterior which include a special Green Hell Magno paint, a more aggressive grille, enlarged air intakes to enhance cooling (required by the more powerful engine), rear wing that increases downforce at rear. The car’s underbody has been revised to improve airflow.</p><p>Even the standard variant, a strong performer already, made alluring sound that's critically acclaimed. AMG GT R receives a new exhaust system which is lighter by 5.9 kg than what on offer in S variant. What's absolutely new is rear wheel steering to make this car more agile in corners. Upto speeds of 100 KMPH, the rear wheels will turn in opposite direction of front wheels, but over 100 KMPH, the rear wheels will turn in same direction as front . This improves stability at high speeds and also handling. An electronically locking differential is standard feature of GT R and traction control has 9 selectable settings.</p><p>The cabin also is upgraded with AMG performance seats been standard equipment (with Nappa Leather). As an option, buyers can opt for yellow seat belts while yellow highlights for instrument console are part of standard equipment.</p><p></p>
