There are two variants available in Mercedes-Benz AMG GT i.e. Roadster and R. The Mercedes-AMG GT R is the most hardcore version of the standard Mercedes-AMG GT. It is powered by a 4.0-litre twin-turbo V8 petrol engine that produces 585PS of power and 700Nm of torque. Mated to the engine is a 7-speed, dual-clutch transmission that sends the power to the rear wheels only. It completes the 0-100kmph sprint in 3.6 seconds and can reach a top speed of 318kmph. The other offering, the Mercedes-AMG GT Roadster, also gets the same engine as the GT R but in a detuned form. It generates 476PS of power and 630Nm of torque. Transmission duties are handled by the same 7-speed dual-clutch gearbox and power is also sent to the rear wheels only. 0-100kmph is dealt in 4.0 seconds and the car tops out at 302kmph. Helping that cause is AMG\'s favourite 7-speed dual-clutch transmission, which doesn\'t leave much room for complaint. The gearbox now also lets you launch the car at higher revs than the GT S for quicker race starts. But the party piece is the nine-step traction control adjustment which lets the driver fine-tune the level of slip on the rear axle with a knob on the centre console. In a nutshell, it will let you pull the smokey stuff through the corners and still manage to get a blisteringly fast exit. Even the exhaust system has been engineered to produce a note evocative of AMG\'s GT3 racecar. It snarls with every breath even at crawling speeds and roars as you race for the redline. There are plenty of crackles and pops on the overrun, but hearing how angrily she breathes, you would also expect the GT R to spit and drool like a beast. Overall it offers a great balance of styling, performance, handling. Do take a test drive in order to clear your all doubts. Check out the nearest authorised deaelrship details.
