奔驰-AMG近日发布了2018款GT R。该车与GT外观有所不同，它采用了外延式轮拱，独特的AMG绿色车身涂装。它的车身底部采用碳纤维部件，当车辆以赛车模式行驶，时速超过50英里（约合80公里）时，车身高度可降低1.6英寸（约合40.6毫米）。这将使车头抬升进一步降低，整个车身就像用胶水粘在路面上一样。同样，为了提升性能，GT R的车身线条更锐利，比GT标准版的空力性能更优异。由于欧规GT R更广泛的采用了轻量化材质，它的重量比奔驰-AMG即将推出的GT S还轻了大约200磅（约合90.8公斤）。该车的前轮拱，车顶面板和驱动轴都采用碳纤维材质，同时还配备了锻造轮圈，另外还拆除了一些隔音材料。GT R搭载了取自GT的4.0升V8双涡轮引擎，但进行了升级，功率达到577马力@6250转/分，比GT S还增加了74马力；扭矩516磅-英尺@1900-5500转/分（约合700牛米）。与引擎搭配的七速双离合器变速器将动力传递至后轮，车辆0-96公里/小时加速时间3.5秒，最高时速200英里（约合322公里），而它的排气系统则采用钛金属和很薄的钢制材料。
Mercedes-AMG GT R breaks cover with 577 hp
Mercedes-AMG has introduced the 2018 GT R after a lengthy teaser campaign.
The GT R further stands out from the GT thanks to subtly flared fenders. Buyers looking to really turn heads can order the GT R in a specific shade of green called AMG green hell magno, a name chosen as a homage to Germany's famed Nürburgring track.
There's more to the GT R than meets the eye. Notably, its underbody is fitted with a carbon component that moves down by about 1.6 inches when the car is in Race mode and driving above 50 mph. This creates a Venturi effect that keeps the GT R glued to road by reducing lift on the front axle. As a result, the R is sharper and more dynamic to drive than the standard GT, especially on the track.
In Euro-spec trim, the GT R weighs about 200 pounds less than the GT S -- the next model down in the lineup -- thanks to the widespread use of lightweight materials. AMG points out that the front fenders, the roof panel, and the driveshaft are all crafted out of carbon fiber. The company has also made the GT lighter by fitting forged wheels and removing a good deal of the sound-deadening material.
The R uses an evolution of the GT's twin-turbocharged 4.0-liter V8 engine that has been tweaked to provide 577 horses -- 74 more than the GT S -- at 6,250 rpm and 516 pound-feet of torque from 1,900 to 5,500 rpm. A seven-speed dual-clutch transmission sends power to the rear wheels, allowing the GT R to hit 60 mph from a stop in 3.5 seconds and go on to a top speed of nearly 200 mph. The eight-cylinder breathes through a sport exhaust system made with titanium and thin steel.
