Without a doubt, the Mercedes-AMG GT R it’s in its own right the most radical and fastest AMG of the moment. What the hell, it’s one of the most radical AMGs ever. Yesterday’s leak already gave us clues about its appearance and performance, but we finally have all the official information for you. The Mercedes-AMG GT R is a Mercedes-AMG GT squared, more powerful, faster and more aerodynamic. The fact that it was developed entirely at the Nürburgring gives clues about his character.
Active aerodynamics – much more than a body kit
The angle of the rear spoiler is manually adjustable, depending on each circuit. It is designed with the slopes in mind.
The Mercedes-AMG GT R stands out for its peculiar shade of paint, a matte green named “AMG Green Hell Magno””. Looking at it, we might think that it only equips a more aerodynamic body kit, but we would be very wrong. This body kit has been meticulously created in the wind tunnel, and launches solutions active aerodynamics: under the front, a carbon fiber flap moves downwards by about 40 mm, creating a venturi effect that sticks the car to the ground. At 250 km / h, it generates 40 kilos more of downforce.
This carbon fiber flap is joined by a flat bottom for the car’s underbody, a much larger and more sculpted rear diffuser, and a Fixed spoiler on the boot lid. The grille also has mobile elements that modify its position looking for an optimal aerodynamic coefficient for each dynamic requirement. All the details of its body are designed for this purpose, with the collateral benefit of giving the car a more threatening appearance: at its top speed, its downforce is 155 kg higher than a standard GT.
Function over form: an optimized undercarriage
Its front is a tribute to the Mercedes-AMG GT3 and the 300 SL of the Carrera Panamericana.
Their widened wheel arches are not posture: they allow 75mm wider track width at the rear. These wheel arches can accommodate 20-inch diameter wheels, wrapped in Michelin Pilot Sport Cup 2 tires – semi-slicks for all purposes – in size 325/30 ZR 20 for the rear axle. On the front end, these tires have 275 mm section and are mounted on 19-inch wheels. Inside it, a huge braking equipment has been mounted, with yellow painted brake calipers.
The optional carbonceramic kit has 402 mm diameter discs on the front axle and 360 mm on the rear axle. The dark roof of the Mercedes-AMG GT R is not decorative, it is really an element of carbon fiber, designed to reduce the overall weight of the assembly. The drive shaft from the engine to the wheels is also made of carbon fiber, as well as certain elements of the suspension scheme and some car structural reinforcements. They are techniques directly derived from the racing Mercedes-AMG GT3.
What record at the Nürburgring will Mercedes-AMG surprise us with?
The use of light metals such as magnesium or aluminum also contributes to the very low weight of this car: empty it only weighs 1,555 kilograms, despite being equipped with a heavy front-facing V8 and a dual AMG SPEEDSHIFT gearbox. clutch and 7 relations in transaxle position. In the rear axle they have installed an automatic steering rear wheel system: they rotate jointly with the front wheels from 100 km / h and in the opposite direction at a lower speed. They give the car better cornering.
585 hp of power and blazing performance
Its benefits are dazzling: 0 to 100 km / h in 3.6 seconds and 318 km / h of tip.
The 4.0 V8 Biturbo engine of the Mercedes-AMG GT R now develops 585 horsepower. It has no substantial changes compared to the engine of the other AMG GTs, although it has received a tune-up and its turbochargers blow at 1.35 bar instead of 1.2 bar. Furthermore, both engine and transmission are mounted on Active silent blocks, similar to the Porsche solution in the 911 GT3. The result is again, better cornering and greater dynamic efficiency. The exhaust system is even sportier, with a more aggressive sound.
The engine power becomes 585 hp, and its maximum torque grows to a whopping 700 Nm, available between 1,900 rpm and 5,500 rpm. The Mercedes-AMG GT R manages to accelerate up to 100 km / h in 3.6 seconds, while its top speed increases to 318 km / h. The difference is in twisty tracks, in circuits like the Nürburgring where its set-up comes out. Of course, her driving modes, her. AMG TRACTION CONTROL designed in competition and its limited-slip differential have received a new set-up.
What will this beast be capable of? It is clear that Mercedes will seek to break records at the Nürburgring, and they do not lack material.
