Specifications and performance
The M178 V8 engine in a GT. The turbochargers are visible in the centre, beneath a metallic heat shield
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. 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. 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).

F1 Safety Car
Mercedes-AMG GT S Formula 1 safety car
The GT S was the Formula 1 safety car for the 2015 season, having made its debut in that role at the 2015 Australian Grand Prix. Since 2018, the GT R has replaced the GT S as F1’s current safety car.
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) and the inclusion of the ‘Panamericana’ grille from the GT3, GT4 and GT R variants as standard equipment for all variants.
In March 2015, Mercedes-AMG presented the AMG GT3, a race version of the GT, at the , 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.
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 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 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. 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.
As of June 2019, a total of 130 GT3 cars were sold.
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.
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. The exterior lead designer was Mark Fetherston, whose previous works include the W176 A-Class, the CLA-Class, and SLS AMG. The interior, designed by Jan Kaul, features a large centre console and decorative elements in a leather and carbon polymer design. The trunk offers room for a medium-sized suitcase.
