Mercedes-AMG GT

The Mercedes-AMG GT (C190 / R190) is a grand tourer produced in coupé and roadster bodystyles by German automobile manufacturer Mercedes-AMG. The car was introduced on 9 September 2014 (2014-09-09) and was officially unveiled to the public in October 2014 at the Paris Motor Show.[4] After the SLS AMG, it is the second sports car developed entirely in-house by Mercedes-AMG. The Mercedes-AMG GT went on sale in two variants (GT and GT S) in March 2015, while a GT3 racing variant of the car was introduced in 2015. A high performance variant called the GT R was introduced in 2016. A GT4 racing variant, targeted at semi-professional drivers and based on the GT R variant, was introduced in 2017. Recently, a new variant called the AMG GT Black series has been released. All variants are assembled at the Mercedes-Benz plant in Sindelfingen, Germany.

History
Mercedes-AMG GT S

The interior of the Mercedes-AMG GT was previewed on 16 April 2014.[5] The car made its debut on 9 September 2014 and was officially unveiled to the public in October 2014 at the Paris Motor Show with two engine power output options: the GT, with 340 kW (462 PS; 456 hp), and the GT S with 375 kW (510 PS; 503 hp).[4] The GT generates 600 N⋅m (443 lb⋅ft) of torque, and the GT S generates 650 N⋅m (479 lb⋅ft) of torque.[4]

Shortly after its introduction, Mercedes-AMG CEO Tobias Moers promised a Black Series variant of the Mercedes-AMG GT.[6] The new high performance variant was called the AMG GT R.[7]

F1 Safety Car
Mercedes-AMG GT S Formula 1 safety car

The GT S was the Formula 1 safety car for the 2015, 2016 and 2017 seasons, having made its debut in that role at the 2015 Australian Grand Prix.[8][9] Since 2018, the GT R has replaced the GT S as F1's current safety car.[10]

2017 facelift

The Mercedes-AMG family was given a facelift in 2017, along with the introduction of the GT C roadster variant and the Edition 50 model, which is a limited-edition derivative of the GT C variant. The key improvements made as part of the facelift include increased power output from the M178 engine for the GT and GT S variants (10 kW and 9 kW respectively)[11] and the inclusion of the 'Panamericana' grille from the GT3, GT4 and GT R variants as standard equipment for all variants.[12]

Features

The GT's exterior design was kept similar to that of the preceding SLS AMG. It features the wide wheel arches, lower bodywork, and fastback sloping roofline of the SLS AMG, but uses conventional forward-opening doors instead of the iconic gullwing style pioneered by the 300 SL in the 1950s. The large bonnet and slim windscreen have been retained. The vehicle structure is made up of 93% aluminium, with the front module base made up of magnesium.[13] The exterior lead designer was Mark Fetherston, whose previous works include the W176 A-Class, the CLA-Class, and SLS AMG.[1] The interior, designed by Jan Kaul, features a large centre console and decorative elements in a leather and carbon polymer design.[2] The trunk offers room for a medium-sized suitcase.

Specifications and performance

The GT uses a front mid-engine, rear-wheel-drive layout, with the engine positioned inside of the vehicle's wheelbase. The spaceframe chassis and body are made out of aluminium alloys, while the trunk lid is made of steel and the hood is made of magnesium.[4] The suspension system is a double wishbone unit at the front and rear, with forged aluminium wishbones and hub carriers.

The car is powered by a 4.0-litre M178 twin-turbocharged V8 engine. The engine is in "hot inside V" configuration—with exhaust manifolds and turbochargers inside the cylinder banks to reduce turbo lag—and uses dry-sump lubrication. Power is sent to the rear wheels through a seven-speed AMG SPEEDSHIFT dual-clutch transmission; the GT S variant employs an electronically controlled mechanical limited-slip differential.[14] In a road test executed by Car and Driver, the GT S accelerated from 0–97 km/h (60 mph) in 3.0 seconds, completed the quarter mile in 11.2 seconds and attained a top speed of 311 km/h (193 mph).[15]

Variants

Mercedes-AMG GT (2015–present)

The GT is the entry level variant of the Mercedes-AMG GT family. The M178 engine in this variant is tuned to an output of 350 kW (476 PS; 469 hp) and 630 N⋅m (465 lb⋅ft) of torque, with the key differences between this and its more expensive siblings being a mechanical limited-slip differential, an absorbent glass mat battery, the lack of the "Race Mode" and "Race Start" mode settings in the AMG Dynamic Select adaptive drivetrain system, the lack of the AMG Ride Control adaptive suspensive system, and a passive AMG Sport Exhaust System. Keyless-Go is also an optional feature, as opposed to standard equipment. The GT is equipped with 19-inch wheels at the front and rear.

Mercedes-AMG GT S (2015–present)

The GT S is a more highly equipped variant of the Mercedes-AMG GT. The M178 engine in this variant is tuned to an output of 384 kW (522 PS; 515 hp) and 671 N⋅m (495 lb⋅ft) of torque. The key mechanical differences the GT S gains over the GT include an electronically controlled limited-slip differential, "Race Mode" and "Race Start" mode settings in the AMG Dynamic Select adaptive drivetrain system, AMG Ride Control adaptive suspensive system, an AMG Performance Exhaust System with dynamic flaps, and a lithium-ion battery. Keyless-Go is standard equipment, as is a staggered set of wheels (19-inch at the front, 20-inch at the rear).

Mercedes-AMG GT C (2017–present)

The GT C is a performance oriented variant of the Mercedes-AMG GT. The M178 engine in this variant is tuned to an output of 410 kW (557 PS; 550 hp) and 502 lb⋅ft (681 N⋅m) of torque. While the GT C retains the key mechanical differences the GT S gains over the GT, it also has a wider body (2,007 mm (79 in)) and active rear steering, which the GT S does not have (even as options). In the United States, the Lane Tracking and AMG Dynamic Plus option packages are standard equipment on the GT C.

A limited-edition model, the Edition 50, was released as part of the debut of the GT C variant at the 2017 Detroit Auto Show. The Edition 50 features: a choice of two shades of matte paint known as designo Graphite Grey Magno and designo Cashmere White Magno; black chrome exterior trim, headlight surrounds and forged / cross-spoke wheels; a two-tone silver pearl or black against grey quilted-leather interior which features a micro-suede wrapped steering wheel; and, "Edition 50" and "1 of 500" lettering on the steering wheel bezel and 12 o'clock mark in silver pearl. In the United States, the Edition 50 is limited in production to 50 coupes and 50 roadsters. Globally, the Edition 50 is limited to 500 units, which explains the "1 of 500" on the steering wheel.[16][17][12]

Mercedes-AMG GT R (2017–present)
Mercedes-AMG GT R

The GT R is a high-performance variant of the Mercedes-AMG GT and was introduced at the Goodwood Festival of Speed on 24 June 2016. The M178 engine in this variant is tuned to an output of 430 kW (585 PS; 577 hp) at 6,250 rpm and 700 N⋅m (516 lb⋅ft) of torque at 5,500 rpm. The GT R accelerates from 0 to 100 km/h (62 mph) in 3.6 seconds and has a claimed top speed of 319 km/h (198 mph).[18]

While the GT R retains the key mechanical differences the GT C gains over the GT S, it also gains manually adjustable coilover springs (in conjunction with the AMG Ride Control suspension of the base models), an active underbody fairing, a manually adjustable rear wing, and a 9-mode AMG Traction Control system. As befitting of a high-performance variant, the GT R loses Keyless-Go, the integrated garage-door opener, the heated and power-folding side mirrors, the auto-dimming interior and exterior mirrors and reverts to the basic light-weight 4-speaker audio system that the GT comes with.

When it was launched, the GT R had several cosmetic changes compared with the standard car, notably the vertical slats in the front grille, an adjustable rear wing, new front air intakes and new front and rear diffusers. The styling of the GT R is more comparable to that of the AMG GT3 race car. However, the base GT variant gained several of these cosmetic changes as part of a mild facelift in the 2017 model year. The GT R went on sale in November 2016, with deliveries beginning in 2017.[19] For the 2018 Formula One World Championship, the GT R became the official Formula 1 safety car. During the 2020 Tuscan Grand Prix, the Safety Car ran a red livery rather than the traditional silver to commemorate Scuderia Ferrari's 1,000th Grand Prix start.

It completed a lap of the Nürburgring Nordschleife track in 7:10.92, in a test conducted by German magazine Sport Auto.[20] This earned it the seventh position for street legal vehicles in 2019.

A roadster version was introduced in March 2019 and would be limited to 750 units.[21]

Mercedes-AMG GT and GT C Roadster (2017–present)
Mercedes-AMG GT C Roadster

The GT and GT C roadsters are the roadster versions of the GT and GT C coupés, and were announced shortly after the introduction of the GT R variant.[22] Both variants made their debut at the 2016 Paris Motor Show. The GT and GT C roadsters utilise the active air management system found on the GT R variant to help with cooling and airflow performance. The GT C roadster retains the wider bodywork of the GT C coupé, and the GT roadster has a slightly higher first and lower seventh gear with a longer final drive compared to the GT coupé. The GT and GT C roadsters feature a three-layer fabric roof built around an aluminum, magnesium and steel structure, available in black, red or beige, and which can open and close in 11 seconds up to speeds of 50 km/h (31 mph). The GT C roadster, like the GT C coupé, has a limited "Edition 50" model, celebrating AMG's 50 years of existence.[23][22]

A 5-door liftback version of the AMG GT was introduced at the 2018 Geneva Motor Show.

Mercedes-AMG GT Black Series (2021–present)

The GT Black Series is a high-performance variant of the Mercedes-AMG GT and was officially revealed on Mercedes-AMG's YouTube channel on 9 July 2020. The M178 engine in this variant is tuned to an output of 537 kW (730 PS; 720 hp) at 6,700-6,900 rpm and 800 N⋅m (590 lb⋅ft) of torque at 2,000-6,000 rpm. Referred to as the M178 LS2, the engine has a slightly higher redline at 7,200 rpm compared to the GT R's 7,000 rpm, and uses a flat-plane crankshaft instead of a cross-plane crankshaft, turning out in different firing order. Additionally, the M178 LS2 uses a larger compressor wheel, resulting in an increase in boost from the GT R's 19.6 psi to 24.6 psi. The GT Black Series accelerates from 0 to 100 km/h (62 mph) in 3.2 seconds and has a claimed top speed of 325 km/h (202 mph).[25]

The suspension is unique, with a carbon-fibre anti-roll bar with two adjustment settings for the front axle, and an iron anti-roll bar with three adjustment settings for the rear axle. Like previous Black Series cars, the camber is manually adjustable for both the front and rear axles. Handling has been improved with carbon-fibre panels at the front and rear, as well as carbon-ceramic rotors and Black Series specific brake pads. The wing has an active aero flap, and contributes to a total maximum downforce of more than 400 kg (882 lb) at 249 km/h (155 mph). The Michelin Pilot Cup 2 R tyres are specific to the car, and are available in M01A soft and M02 hard compounds.[26]

Carbon-fibre is used extensively for most of the body, including the hood, roof, hatch and underbody. The exterior gains an enlarged grille, based on the Mercedes-AMG GT3, large air outlets on the hood, manually adjustable front splitter, and upgraded rear wing as part of a major aerodynamic kit. The interior features standard AMG performance bucket seats, and uses microfiber for the steering wheel, door and instrument panels.[27]

On 4 November 2020, the Mercedes-AMG GT Black Series posted a time of 6:43.616 under driver Maro Engel at the Nürburgring Nordschleife, becoming the fastest time ever for an unmodified car.

Motorsport

In March 2015, Mercedes-AMG presented the AMG GT3, a race version of the GT, at the Geneva Motor Show, which employs the M159 6,208 cc (6.2 L) V8 naturally aspirated engine also used in the SLS AMG GT3. It consists largely of carbon-fiber-reinforced polymer to decrease the vehicle's weight to under 1,300 kg (2,866 lb) to comply with FIA regulations for races.[28] In 2016, AKKA ASP, Black Falcon, HTP Motorsport and Zakspeed compete in the Blancpain Endurance Series. Zakspeed also competes in the ADAC GT Masters. They claimed a 1-2-3-4 and 6 at the 24 Hours Nürburgring.

In the 2016 Super GT GT300 class, the AMG GT3s made their Super GT debut with Goodsmile Racing with Team UKYO, the number 11 GAINER team, LEON Racing, and Rn-sports opting to use the AMG GT3s in favor of the SLS AMG GT3s that they used in the previous season. Two Mercedes customer teams, R'Qs Motor Sports and Arnage Racing, opted to continue using the SLS AMG GT3s. Both of them would switch to AMG GT3s during the 2018 season, switching from SLS AMG GT3 and Ferrari 488 GT3 respectively.

New Zealand born driver Craig Baird gave the new AMG GT3 its first race win anywhere when he took out race 1 of round 2 of the 2016 Australian GT Championship at the Melbourne Grand Prix Circuit on 17 March 2016.[29] The round was held as a support race to the 2016 Australian Grand Prix.

Riley Technologies entered two customer AMG GT3s in the 2017 IMSA SportsCar Championship GTD class. One of the teams cars finished 3rd in class and 20th outright at the 2017 24 Hours of Daytona before going on to win the GTD class and finish 16th outright in the 2017 12 Hours of Sebring.

A GT4 version of the Mercedes-AMG GT was presented at the 2017 24 Hours of Spa. This customer racing car is based on the GT R road version and it made its debut in the ROWE 6 Stunden ADAC Ruhr-Pokal-Rennen race, the fifth round of the 2017 VLN season.[30][31]

As of June 2019, a total of 130 GT3 cars were sold.[32]

An updated version of the GT3 was introduced at the 24 Hours of Nurbürgring in June 2019 for the 2020 season of the FIA GT3 race. New technologies include an automatic data logger and analysis system, a function to automatically start the engine when the car is lowered from its in-built air jacks along with new brake and traction control systems. The design was also updated in line with the design of the new design update of the AMG GT road car with the changes being the new headlamps and the grille with the latter providing better protection for the radiator. The front splitter and rear wing were tweaked in order for faster adjustments. The car uses the same 6.3-litre V8 engine as the previous model rather than the 4.0-litre V8 engine of the road car it's the engineers stating the user friendliness and reliability of the engine as the main factor of its retention.[33]
