AMG GT R reveal

Mercedes AMG introduced, in the Goodwood Festival of Speed, and with the craziest possible way, its new AMG GT R, which is a new variant of the AMG GT, that comes with sportier looks, faster, more powerful, and with a better brain. The AMG GT R, came from the sky, lifted by a helicopter and deposed in the Mercedes-Benz World test track in Brooklands, to be welcomed by an AMG GT-S and the AMG GT3. The introduction came hand in hand with the celebration of a 1,2,3 podium at the Nurburgring 24h. The three cars came straight to business, having fun, being tail happy, drifting, and giving it their best. It was all spectacular.

First thing is first, the completely new look, the AMG GT R comes in a vibrant shade of green, after its teaser being made in forest, by the triple F1 world champion, Louis Hamilton. The car sits on lightweight, AMG performance wheels, in black matte color. The wheels were adjusted as follow, 19 inch to the front, and 20 inches to the rear, all four wheels have 325 wide Michelin Sport Cup 2 tires. The car has a low slug front section, with a forward inclined radiator vertical-strats grille which give it a shark nose expression. After spending many an hour in the wind tunnel, testing, and being reshaped, the AMG GT R came with a aerodynamic, muscular aggressive profile. Front fenders were used for both weight reduction, and better aerodynamic results, it also gives the car 1.8 inch more in width. In the rear, it has a large rear diffuser, new aluminum side walls, which allow a 2.2 inches addition to the width. It has a new air spoiler, and for weight gain, a high grade carbon roof. Total weight gain was 15 kgs compared to the AMG GTS.

Under the bonnet lays the power train of the AMG GT R, the 4.0L twin Turbocharged tweaked V8 engine, the same M176 engine put inside the standard GT, but with more tweaks, is able to reach the same power figure as the old 5.5L M157 engine. So now, the engine unleashes 585 bhp, has a crazy torque of 700 Nm. Standing start to 100 kph takes 3,6 seconds which the same as the GT S variant. Top speed will be around 320 kph. All this was achieved thanks to the AMG speedshift DCT 7-speed automatic transmission. Not only that, but the new turbochargers fitted to the engine, have now 0,15 bars more compared to the old ones.

On the inside, the old seats were removed, and instead, AMG fitted its sport, manually adjustable, seats for light weight. They are covered in NAPPA leather, and DINAMICA microfibre components, guess that the tailors at Mercedes AMG know what luxury, and being suited up means. The car comes with new AMG Interiour night package. Elements such as the infotainment system, the Burmester Sound System and Climate control were kept despite trying to save weight. Then, we go the buttons, and settings. The new AMG GT R is the first ever Mercedes Benz to feature rear-axle steering : at low speeds, the rear wheels tend to turn opposite to the front wheels, to have a tighter turning circle, whereas, at high speed, the rear wheels turn parallel to the front wheels to gain on stability. In addition to that, the car has new ESP and Traction Control mode, that works in 9 modes, from wet to off. The driver can adjust dumpers according to three driving modes : comfort for city drive, Sport and Sport plus, for crazy, go fetch drive. For the first time, Magnesium was used on some components to reduce weight. New suspensions were fitted; double wishbones and unibal bearings, for a more track focused drive, and coil cover spring, that adapts to the driving commands.

AMG GT

When it comes to replacing their models, car companies do a crazy job to fix, add, replace.. because the next model has to be better in every way, but what if that car being replaced is the SLS AMG? Kind of the perfect car? How car one replace the perfect car? Mercedes-Benz and AMG had the answer, they outdid themselves, and created the AMG-GT model, a rocket that was made to compete with Porsche 911, Jaguar F type R, Audi R8, Corvette, Aston Martin Vantage. There is a new version, and it is more powerful, faster, and in some way better than the AMG GT. It is the AMG GT S, where S means here 50 more bhp.

So as expected, the car came to play in the big league, and it is not to be messed with. It is fitted with the same 4.0L V8 biturbo engine, with turbos mounted inside the V, it is to achieve greater thermal efficiency. The engine is able to produce 510 bhp, all of them going to the rear wheels, and 479 lb-ft of torque between 1,750 and 5,000 rpm. It is coupled with a seven-speed dual-clutch automatic transmission. The result is, 0 to 60 in a lighting 3.6 seconds. Mercedes-AMG will need to do a better work though, to beat the 3.0 seconds of the Porsche GT3, and 3.5 seconds of the Jaguar F-type. The car top speed is limited at 196 mph which lessens the fun. Mounting the turbos inside V creates a more compact engine, to gain space. Mercedes-AMG uses dry sump to guarantee a better lubrication for the engine. Having a smaller engine won’t mean that the car will make less noise than its AMG predecessors, the exhaust system creates the kind of noise that announces the car coming from miles.

The interior was made to be just perfect. It is similar to the SLS, spaceship craft was present, with all the buttons, knobs and switches, especially with the central console, so get ready to launch your missiles. These features allow you to control the power distribution, steering, driving modes, and lots of stuff. For example, the Sport Plus mode offers a more aggressive driving through firm steering, lightning gear-changes, and throttle mapping. The car has a large leg and head rooms. It has a large steering wheels, the seats have carbon fiber backs, some expensive materials were used, like aluminium, soft leather, carbon-fiber…. The car has large air intakes, and a good balance of colors.

As we said, The AMG GT is based on the SLS Mercedes, it has the same long nose, looks a bit like it, but in its own way. It is as wide, it has the same front suspension, while the rear suspension is custom-made just for it. It has iron adaptive suspension dampers, aluminum double-wishbone suspension, low center of gravity, electronically controlled mounts for the engine and the gearbox. The engine is mounted more the rear, while the gearbox sits on the rear axle, giving the car better agility, and a weight distribution towards the rear, (53% of the mass goes the rear axle, while 47% to the front). The car has an electronic differential mounted on the rear axle. An impressive feature about the car, is the hydraulic steering, which makes more car and less computer of it, to give that sensation of control of the driver, instead of all the electronics doing the job for him, and the result is more controllable, less nervous steering than the SLS.
