Mercedes-Benz AMG GT-S

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 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.

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 at the time, 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.

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.[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).
