Mercedes brings a street version of the spectacular Mercedes-AMG GT3 in 2016 on the market. Its V8 Biturbo brings 585 hp and a lot of racetracks features make it the road-going GT3.
Mercedes-AMG GT R with expressive look
The stated goal: They want to attack Porsche 911 GT3, and as it should at AMG tradition, you deal with aggressiveness just bluntly to than in Zuffenhausen. In other words, the AMG GT R will strike held taunt. With naked violence, but "högschder" precision, as they say in Vorarlberg. And as you have turned on all relevant screws. And strong.
Visually, the AMG GT R clearly shows its descent from the GT3 racing version. Wider front and rear mudguards wider track enable (46 mm at the front, 57 mm at the rear) for more traction and even higher cornering speeds. The new forging wheels carry the dimensions 10 x 19 and 12 x 20 inches and with Michelin Pilot Sport Cup 2 tires in the size 275/35 ZR 19 the front and rear 325/30 ZR 20 equipped.
The new front bumper with active elements (from 80 km / h moves from a carbon spoiler; the radiator fins can be closed), the large rear wing with an adjustable blade and the new rear bumper with double diffuser to increase aerodynamic efficiency and contribute to optimum grip. Also new is the active rear are (deflected by up to 1.5 degrees with) the fully adjustable sports suspension with electronic damping control and the nine-adjustable traction control. the hood and the grille was changed. Here the so-called Panamericana grill comes on the AMG GT R first used. The roof of the GT R is made of carbon.
First contact and seat fitting at the Mercedes AMG GT R
Who is at the AMG GT R, may it difficult to ascertain how much the new variant of the previously known AMG GT and GT S is different. Sure, the color of the wings is striking the Panamericana grille can not be overlooked with the vertical struts, especially behind considerably wider at second glance. At the latest at the tail might suggest clueless that was a GT3. But inside are the GT R then the road-going sports cars. Although the seats are extremely cupped and you learn at the presentation that they bring 16 kilos of weight savings, but the cockpit and instruments act civil, carpets and panels create an almost homely atmosphere. But among the air vents on the center console sits a rotary knob with a plastic head the diameter of a 5-cent piece, whose strong lemon yellow stands in contrast to the black auffälligstem Cabon- and plastic coverings its surroundings. Only the belts and the decorative seams of Alcantara upholstery are just as yellow.
The knob adjusts the sensitivity of traction control. And in nine levels. It was the brainchild of AMG boss Tobias Moers and recalls what the GT R is made despite street legal: for racing. "The classic is the mousetrap on Bilster mountain. There, a crest relieved briefly the rear axle. Who then too strong stands on the gas, which is struggling with a sudden loss of traction and rear outburst. The guardrail there can sing a song about it - many strikes. With the yellow button you can set how much the traction control to limit the slippage at the rear axle. This actually works like in Formula 1 - and in some places it sounds even quite similar, "says Moers.
The changes in the AMG GT R come from the same meticulous improvement work on the basic concept of the sports car. Nearly Affalterbach have scrutinized everything, new solutions, often inspired, weighed and simulated by the GT3. Promising were apparently among others: a rear axle (premiere in a Mercedes), the carbon tube for the propeller shaft, cross-shaped bracing underneath, also made of carbon, a fully variable locking differential, a new front axle, parts of the front of magnesium, an outlet for the heated by the exhaust gas air under the vehicle between the rear lights, the exhaust system with the three tail pipes, in which the outer only be passed through when the exhaust valve opens and so on.
In view of this effort, the secrecy on the price seems to have a good reason. But Tobias Moers is sure. "Sure must also have a GT R bring a comparable contribution margin as the other GTs, but the price is a positive surprise." And that AMG will bring the GT "three or four other variants" because Moers is already certain. One of these will debut in March before the launch of the GT R - perhaps a GT4?
GT-R makes 585 hp in the road version
Under the hood, it is then passed to the direct connection to the race car. During the GT3 is still working with the known from the SLS 6.2 liter V8 vacuum cleaner with a capacity of 500 to 520 hp, comes in Mercedes-AMG GT R the four-liter V8 biturbo used. Which was for his new field of application mainly with new turbochargers with optimized compressor side, a tickle from 1.2 to 1.35 bar boost pressure increased and a new engine management software to 585 hp and 700 Nm of torque. By comparison, the AMG GT S has 510 hp. A 7-speed double-clutch transmission with longer and shorter first seventh speed forwards in the GT R, the drive torque via an electronically controlled limited-slip differential on the rear axle. In 3.6 seconds, the GT R will sprint to 100 kph, the maximum speed is reached at 318 km / h. The standard consumption is Mercedes with 11.4 liters.
Premiere at the Festival of Speed at Goodwood
Inside was a standard night package with many darkened components ensures greater sportiness. In addition, Matt Carbon applications are to be had. Lightweight construction: the Mercedes-AMG GT-R uses a front cover made of magnesium, front fenders and torque tube made of carbon, a titanium muffler, lightweight forged wheels, a lighter dual-mass flywheel, Radfangstreben from composite and less insulation material. In total, 15 kg were saved, the DIN-weight dropped to 1,555 kg. The power to weight ratio should be at 2.66 kg / hp.
In addition to the fine tuning of all components three points are fundamental. First, the reduced Karosserietorsion. About a so-called tunnel cross made of carbon fiber, which supports the two sides of the vehicle in the area of the torque tube tunnel against each other, the stiffness increased by 7.5 percent.
supported the whole - second - from a spurverbreiterten Gewindefahrwerk with enlarged wheel dimensions, as standard Cupbereifung, Unibal link bearings on the rear wishbones and the steered by up to 1.5 degrees rear axle. Depending on the speed it supports either the agility and stability and is in turn supported by the equally active as adaptive aerokit - the third elementary point.
In addition to the manually adjustable rear wing there are electric motor-controlled elements in the bow area used. These are, for a blinds in the skirt and current increase in the closed state air resistance and only open when required by the thermal. On the other is located below the splitter, a carbon plate from 80 km / h extends by about 40 millimeters down. The purpose: to generate a Venturi effect, ie suction of the cars on the road. Exact values AMG wants to not cough up, only that the Vorderachsauftrieb thereby reducing 250 km / h: about 40 kg.
And where will it all lead? Well, on the small track in Hockenheim the target time frame is well below the 1.5 seconds AMG GT S, ergo in the area deeper one-eighth times.
His premiere of the Mercedes-AMG GT R in the exclusive color "AMG magno green light" at the Festival of Speed at Goodwood. In the trade it comes only in March 2017 on order it is from 21 November 2016, the basic price is 165,410 euros.
