The Mercedes-AMG GT

The first Mercedes was a racing car, its most recent successor carries this heritage forward: with the new Mercedes-AMG GT, the Mercedes-AMG sports car brand is moving into a new, top-class sports car segment for the company.

The first Mercedes was a racing car, its most recent successor carries this heritage forward: with the new Mercedes-AMG GT, the Mercedes-AMG sports car brand is moving into a new, top-class sports car segment for the company. The GT is the second sports car developed entirely in-house by Mercedes-AMG. Its front mid-engine concept with transaxle and the intelligent aluminium lightweight construction form the basis for a highly dynamic driving experience. Its likewise newly developed AMG 4.0-litre V8 biturbo engine underscores the hallmark AMG driving performance. The first sports car engine with internally mounted turbochargers ('hot inside V') and dry sump lubrication is configured in two output ratings: as a GT with 340 kW (462 hp) and as a GT S with 375 kW (510 hp). The new GT combines driving dynamics and first-class racetrack performance with superb everyday practicality, and efficiency that sets new standards in the segment.

It has everything you would expect from an authentic Mercedes-AMG sports car – from the characteristic styling, thoroughbred motorsport technology to the optimum weight distribution. The drive system tailored consistently to driving dynamics perfectly complements this set-up. The centrepiece of the Mercedes-AMG GT, the new 4.0-litre V8 biturbo, responds instantly with extreme power right from low revs and delivers outstanding performance. Top figures such as 3.8 seconds from zero to 100 km/h and a top speed of 310 km/h, combined with the outstanding driving dynamics will undoubtedly translate into extremely fast laps on the racetrack.

At the same time, the two-seater is a straightforward, comfortable and reliable companion for everyday motoring thanks to its practical tailgate, easily accessible luggage compartment, high level of comfort on long journeys and the extensive Mercedes-Benz Intelligent Drive assistance systems.

"With the new Mercedes-AMG GT, we are venturing out into a challenging sports car segment with its top-class competitive field. This is an incentive and motivation for us at the same time to prove to sports car enthusiasts around the world the kind of performance that AMG is capable of", says Prof Dr Thomas Weber, Member of the Board of Management of Daimler AG, responsible for Group Research & Mercedes-Benz Cars Development.

"With the new GT we are positioning Mercedes-AMG even more aggressively than to date as a dynamic sports car brand", says Tobias Moers, CEO of Mercedes-AMG GmbH. "With its technological substance, the Mercedes-AMG GT fulfils our high aspirations with regard to driving dynamics, agility and sportiness. The new GT is the second sports car developed fully independently by Mercedes-AMG. The car is manufactured according to the motto 'Handcrafted By Racers' – which perfectly encapsulates our heritage and our spirit."

The combination of aluminium spaceframe, V8 biturbo engine with dry sump lubrication, seven-speed dual clutch transmission in transaxle configuration at the rear axle, locking differential, sports suspension with aluminium double-wishbone suspension and the low kerb weight of 1540 kilograms delivers racetrack performance. The concept with front mid-engine and transmission in transaxle configuration makes for a beneficial weight distribution of 47 to 53 percent between the front and rear axle. In conjunction with the vehicle's low centre of gravity this translates into extremely agile handling and permits high cornering speeds. With a favourable power-to-weight ratio of 3.3 kilograms per hp, the Mercedes-AMG GT self-confidently lines up alongside the very best in its segment. The sports car also sets a new benchmark figure for fuel economy: fuel consumption of 9.3 litres per 100 kilometres (NEDC combined) constitutes a considerable increase in efficiency.

Exterior design
"The new Mercedes-AMG GT is a sports car in its purist form", says Gorden Wagener, Vice President Design Daimler AG. "Breathtaking proportions, powerfully sculpted surfaces and flowing lines turn the new AMG into a contemporary sports car which embodies the spirit of the glorious Mercedes sports cars. The GT is a consummate combination of beauty and intelligence."

The new Mercedes-AMG GT embodies the sensual purity of sportiness and emotion. The two-seater is characterised by hallmark rear-wheel-drive proportions. The V8 biturbo front mid-engine ensures optimum weight distribution, which forms the basis for superb driving dynamics. The long bonnet with its pronounced powerdomes, the greenhouse which has been moved far back, the large wheels and broad tail end make up the distinctive looks. The large tailgate conceals a practical luggage compartment.

Muscular and dramatic dynamism
Positively arched surfaces give the Mercedes-AMG GT its sensuous character and the appearance of a sculpture. Viewed from the side, the dome-shaped, arched roof line and the frameless doors are eye-catching features. A muscular element sculpted out of the side wall creates a sense of lightness and dynamism, even when the vehicle is at a standstill. The surfaces and lines of the side wall flow into the rear-end with a dramatic tapered effect. The GT deliberately avoids lines in the shoulder region. The only line is one lower down, picked up again in the rear bumper, which stretches the body and makes it appear lighter. The side air outlets, each with two fins, represent a typical, styling feature of Mercedes-Benz sports cars. The GT has no visible aerials which could disrupt the overall appearance.

The creative interaction of diverse design elements lends the coupe a superior, self-confident front: the three-dimensional diamond radiator grille with central Mercedes star, a broad louvre and AMG lettering stands in the centre of the front end. LED High Performance headlamps with stylised "eyebrows" as daytime running lamps, side lights and indicators, as well as three separate high-beam reflectors lend the GT its characteristic look.

Large air intakes optimise the flow of air to the cooling modules. The A-wing with front splitter in the lower third of the front apron, a characteristic feature of AMG vehicles, makes the sports car appear low-slung and wide. While the front splitter is painted in the body colour on the GT, it comes with a high-gloss black finish on the GT S. Overall, customers can accentuate the exterior design according to their personal preferences: options available include the Exterior Silver Chrome package, the Night package and the Exterior Carbon-Fibre package.

Broad shoulders
With its base areas, broad shoulders and narrow tail light graphics, the rear area creates an emotional overall appearance. The licence plate bracket is located in the lower part of the bumper, allowing the Mercedes star to be placed prominently on the smooth-surfaced boot lid.

Added to which is an extendable rear aerofoil, which is concealed from view while the car is at a standstill. The black diffuser insert with tailpipes integrated into the bumper and the trim strip in matt iridium silver inspired by the A-wing in the front create a visual sense of lightness across the entire tail end.

Flat, wide tail lights with new sequential turn signals reflect state-of-the-art technology. 18 individual LEDs on each side indicate where the driver intends to turn by sequentially illuminating them from the inside to the outside.
The tail lights underline both the sporty styling of the rear, as well as the attention to detail and sophistication – form and function combine in a unique way to create a perfect unit.

Interior
The interior design too embodies maximum emotion and sensual purity. Radically low, sporty proportions create a unique sense of spaciousness. Clearly drawn components and their authentic materials underscore the dynamic character and create instant excitement: Anyone opening the door discovers an exciting interplay between the deep, sloping dashboard and a dominant, arched high centre console, a design which evokes emotions and impresses with its perfection.

The central "aviation design" theme, which is the hallmark of Mercedes-Benz sports cars, has been restyled. The extreme emphasis on the width of the dashboard, which creates an impression of a powerful wing, dominates the cockpit of the GT. Four central spotlight-style vents and the individual vents at the right and left ends of the dashboard reinforce this impression. In conjunction with the high beltlines, the concave-shaped door panelling and the dynamic centre console, the GT comes across as a genuine driving machine and consummately integrates the driver into the cockpit thanks to the low seat position.

The dominant centre console appears to be a feature lifted straight from motor racing by virtue of its styling that is reminiscent of a NACA air intake, as well as the surfaces and authentic materials that have been used – there is a choice of silver chrome, matt carbon fibre, high-gloss carbon fibre, black diamond and matt silver fibreglass. Positioned centrally, the free-standing central display is an eye-catching feature. Attention to detail is also echoed in the AMG DRIVE UNIT controls: they are arranged like eight cylinders in a V layout, emphasising the powerful and high-tech impression made by the centre console.

Outstanding precision and a superior quality feel thanks to the finest materials with superb workmanship are also apparent on the sports seats, the performance steering wheel and the instrument cluster. The most important control for sports car fans is located in the AMG DRIVE UNIT on the left-hand side: the button for starting the engine, which is labelled "Engine Start Stop" and illuminated in red.

AMG 4.0-litre V8 biturbo
The new high-performance engine springs to life at the push of a button: even the sound as the engine starts up brings you out in goose pimples. The 4.0-litre V8 biturbo engine was developed specifically for the GT. The innovative eight-cylinder engine as the newest member of the BlueDIRECT engine family boasts outstanding power delivery, performance figures on a par with motor racing, lightweight construction as well as high efficiency and environmental compatibility. It boasts the brand's hallmark emotive V8 engine sound, along with an immediate response and high pulling power.

The new V8 also stands out with its precise power output, which is easily a match for a naturally aspirated engine. One development objective that the AMG engine specialists put their heart and soul into and which underline their considerable expertise. The driver truly appreciates the AMG engine, with its internal designation M178, particularly in M, or Race mode in the selectable drive modes, thanks to its linear power delivery, which makes it much easier to handle the vehicle at the limits. As part of this process, the sophisticated ECU even factors in the current driving condition and adjusts the accelerator response depending on the lateral forces generated.

With a displacement of 3982 cc, the V8 uses a range of technologies which are already being used in the 2.0-litre turbo engine in the A 45 AMG, CLA 45 AMG and GLA 45 AMG – presently the most powerful, series-production four-cylinder engine in the world. Both engines have the same bore/stroke ratio, providing the basis for high revving ability. The piezo direct petrol injection used at Mercedes-Benz is responsible for the mixture formation. The spray-guided combustion process was further developed in the third generation to meet all future legal requirements. The highly efficient and economical AMG 4.0-litre V8 biturbo engine meets the Euro 6 emissions standard, including the maximum particulate emissions level that takes effect in 2016.

First sports car engine with 'hot inside V' and dry sump lubrication
The new AMG V8 engine has two turbochargers which are not mounted on the outside of the cylinder banks but rather inside the V configuration – experts call it a "hot inside V". The benefits are a compact engine design, an optimum response from the turbochargers and low exhaust gas emissions thanks to optimum air flow for the close-coupled catalytic converters. The dry sump lubrication also ensures the oil supply even with high lateral forces and allows the engine to be installed lower, thus moving the centre of gravity closer to the road and forming the basis for high lateral acceleration. The new Mercedes-AMG V8 biturbo engine is the world's first sports car engine with 'hot inside V' and dry sump lubrication.

Performance exhaust
The Mercedes-AMG GT S is equipped as standard with an AMG performance exhaust system with fully variable exhaust flaps. This allows the driver to vary the engine sound: depending on the selected DYNAMIC SELECT mode the driver may experience the V8 with a focus on comfort and relaxed, long-distance journeys or with a more powerful, emotive, motorsport-inspired touch. The AMG DRIVE UNIT includes a separate button to control the exhaust flaps directly. The new Mercedes-AMG sports car has its own tonal characteristics which denote the car's membership of the AMG family but that also distinguish it clearly from other high-performance cars. The selectable exhaust system is also available as an option for the Mercedes-AMG GT.

Seven-speed dual clutch transmission
When it comes to the power transmission of the new GT the Mercedes-AMG engineers rely on a combination of front mid-engine and seven-speed dual clutch transmission in transaxle configuration at the rear axle – this layout has already successfully established itself in the SLS AMG. The weight distribution with its ratio of 47 percent (front) to 53 percent (rear) benefits from this configuration. The efficiency, shift speed and precision of the AMG SPEEDSHIFT DCT 7-speed sports transmission were further optimised for usage in the new sports car. Thanks to the larger gear ratio spread, the pronounced torque plateau of the V8 turbo engine can be used optimally. The drivetrain's overall design is ideal for an uncompromising sports car. At the same time, the exacting requirements in terms of everyday practicality, noise level, ride comfort and fuel consumption have been met.

To transfer the driver's shift commands even more directly, communication between the engine and transmission has been fundamentally revised. This means that the previous limits of shift performance and the response time have been substantially increased. The driver can individually tailor the GT to their wishes with the aid of AMG DYNAMIC SELECT. Various modes are available: "C" (Controlled Efficiency), "S" (Sport), "S+" (Sport Plus) and – entirely new – "I" (Individual). The manual "RACE" drive program reserved exclusively for the GT S optimally adjusts the shift strategy of the dual clutch transmission to the needs of racetrack usage – including fastest shift speeds and highly emotive engine. By pressing the "M" button, the driver can activate the manual transmission mode in any drive mode.

Aluminium spaceframe
Mercedes-AMG has gone for an intelligent material mix on the body of the GT. Chassis including greenhouse and body are made out of light alloy, the boot lid out of steel and the front deck out of magnesium. This extremely light element at the front reduces the inertia ahead of the front axle, thus improving the vehicle's agility. Over 90 percent of the weight-optimised spaceframe is made out of aluminium components.

The bodyshell weighs 231 kilograms – a benchmark figure in the sports car segment. There were three key objectives during the design and development of the bodyshell structure: optimum strength, low centre of gravity and low weight. The high bending and torsional strength of the entire design enables
extreme linear and transverse forces from the drivetrain and suspension to be absorbed and transferred. Unwanted flexibility is thus reduced, with the vehicle responding rigidly and directly. As a result, the driver experiences a sports car with maximum dynamism that responds with excellent precision. The aluminium spaceframe also provides the basis for outstanding passive safety.

The Mercedes-AMG GT is produced at Mercedes-Benz in Sindelfingen. The 4.0?litre V8 biturbo engine is manufactured at Mercedes-AMG in Affalterbach.
