Mercedes-AMG GT R: GT has to directional rear axle and active aerodynamics

We knew it was coming and even we could intuit in some unrevealing images, and then know its power and some other interesting data, but the wait is over. Here is the Mercedes-AMG GT R, most sports specialist, which improves GT recipe with better aerodynamics, more power, less weight and a very aggressive look.

The striking body color unit images, called “ AMG Green Hell Great ” is a tribute to the natural habitat of such an apparatus, where Mercedes-AMG says it has carried out much of the radical development of this sport, which has more technology inherited from the competition than any other Mercedes-AMG. The first units will arrive in March 2017, with reservations from November.

Under the long hood of the GT R are the same 4.0 - liter V8 biturbo of his two brothers, although in this case develops 585 hp and 700 Nm of maximum torque also available between 1,900 and 5,500 RPM. This improvement is achieved by blowing new turbos which 1.35 instead of 1.2 bars but still within the V- and changes in electronics, among other things. According to AMG, also it changes the compression ratio (although not specified) and “the combustion process has been recalibrated to complete.”

In charge of change is an automatic dual - clutch transmission and seven - speed, AMG Speed shift DCT 7, setup for an even faster response, of course, send the full force of the rear propeller. The result is acceleration from 0 to 100 km / h in just3.6 seconds, a top speed of 318 km / h and an approved 11.4 liters per hundred kilometers consumption. Here we are presenting a best site to find Mercedes Benz AMG rims for your car.

Solutions high-flying

The impressive aspect of the GT R is played by a wider, namely 4.6 centimeters and 5.7 centimeters behind front necessary to widen the roads and make room wheels and larger tires. Series gums are Michelin Pilot Sport Cup 2 in sizes275/35 ZR 19 in front and 325/30 ZR 20 rear. The rear incorporates a center exhaust outlet and two other discrete integrated into the diffuser.

Bumpers look new invoice entries more generous air, designed to meet the cooling needs. Calls Air Curtains of the side of the bumper also have to be cooled, but in this case the wheel. There are also active nozzles in the nose, which remain closed until additional cooling is needed, time open, improving the flow of air. Even among the rear lights is a small air vent designed to dissipate waste heat from the rear silencer.

In addition, the grill 15 AMG Pan-American chrome vertical slats which already equips the AMG GT3 race but is released in a series- model is complemented by ceiling carbon fiber, lightweight wheels AMG performance in ten - spoke design and color matt black, and new aerodynamic elements like the large rear wing (adjustable and painted in glossy black), double rear diffuser or active parts in the front.

This system of active aerodynamics is new in the model and can vary the aerodynamic profile of the car depending on the situation. It is an airfoil located below the splitter that mode Race moves down 4cm from 80 km / h, altering airflow (accelerating, to be exact) and creating the so - called Venturi effect, which “paste “the front axle to the road to increased down force. Nevertheless, the GT R reduces drag compared to GT, with 155 kilograms of load at maximum speed.

There are also important changes in all that is not visible in this third member of the family GT, designed for the circuit. The suspension type coil over and fully adjustable , with components forged aluminum to reduce weight, and combined with variable damping AMG Ride Control automatic adjustment, which also offers three levels of hardness to choose from ( Comfort , Sport and Sport Plus ). As in the GT S, the engine mounts and transmission are active and vary their rigidity depending on the occasion.

The hindquarter now incorporates a thicker stabilizer bar and the ESP has three modes: On, Off and Sport Handling Mode. Meanwhile, releases a traction control that can be set at nine different levels of intervention -through a selector under the air vents of the console, allowing more or less slip rear axle, where 9 the highest and 1 the ideal for driving in rain. In addition, the system also acts on the limited slip differential, which is controlled electronically.

Another major new feature is the rear axle directional, first used in an AMG model, able to change the angle of the wheels 1.5 degrees. Up to 100 km / h the wheels turn in opposite direction to the front, whereas above this speed they do the same. This means better dynamic skills but also more maneuverability for the day.

Body, although reinforced, makes use of lightweight materials such as aluminum, although throughout the vehicle there are also elements of titanium or carbon fiber (such as the driveshaft, for example, 40% lighter than the GT S). Thanks to the arrangement transaxle of the direct-shift gearbox and seven - speed, the whole weight distribution is 47.3% 52.7% ahead and behind.

Only 15 kilograms less than the GT S, but incorporates many more technical solutions. Meanwhile, by braking it is a system with calipers yellow (exclusive of GT R) and disks ceramic composite of 390 mm ​​front and 360 mm rear. There are also optional high - performance, 17 lighter and 402 mm discs at the front axle kilograms
