2014 Mercedes-AMG GT - Images, Specifications and Information

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 per cent (front) to 53 per cent (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 faster shift speeds and a highly emotive engine. By pressing the "M" button, the driver can activate the manual transmission mode in any drive mode.

The GT comes as standard with a mechanical rear-axle locking differential which ensures outstanding traction and superb driving safety in all driving conditions. The GT S is fitted as standard with an electronically controlled rear-axle locking differential, which is integrated into the compact transmission housing. The electronic function provides even more sensitive, faster control than the mechanical solution, thus pushing the limits of handling dynamics even further. Not only does it further improve the traction of the driven wheels, but also increases the cornering speeds at the limits. The system operates with a variable locking effect in acceleration and overrun mode, and is perfectly tuned to the various driving conditions and road surface friction coefficients.

Driving dynamics and comfort on long journeys; racetrack performance and everyday practicality: the new Mercedes-AMG GT delivers on all counts. A great deal of attention was paid to the seamless integration of all mechanical and electronic systems during the design, development and testing. Whether it is the suspension, 3-stage ESP, locking differential, steering, aerodynamics, tyres or brakes - only the successful precision engineering and concerted networking of individual specialist disciplines manage to produce the required results and thus the exhilarating sports car driving experience, characterised by superb precision and clear feedback.

The AMG GT offers the perfect conditions: it uses the technological DNA of the Mercedes-Benz SLS AMG, one of the most successful sports cars in recent years. Thanks to the optimum weight distribution of 47 percent (front) to 53 percent (rear), the vehicle's low centre of gravity and the selected suspension layout, the driver benefits from precise steering response, formidable agility, low inertia when changing direction, and outstanding traction. Double-wishbone suspension is used at the front and rear - a technology adopted straight from motorsport.

Wishbones, steering knuckles and hub carriers on the front and rear axle are manufactured entirely out of forged aluminium in order to reduce the unsprung masses. The double-wishbone concept locates the wheel clearly with minimal elastic movements. The high camber and track rigidity not only results in high cornering speeds, but also provides the driver with an optimum road feel when cornering at the limit. An extremely direct connection of the shock absorber on the rear hub carrier reduces vibrations and undesirable wheel load fluctuations. Highly neutral behaviour and defined, predictable responses at the tyre grip limit were important development objectives for the dynamic handling experts at Mercedes-AMG.

The AMG Ride Control sports suspension with electronically controlled damping comes as standard on the Mercedes-AMG GT S, or as an option for the GT. The driver can adjust the damping characteristics at the push of a button in the AMG DRIVE UNIT or by using the AMG DYNAMIC SELECT drive modes. Three stages are available: "Comfort", "Sport" and "Sport plus".

The speed-sensitive sports steering features a variable steering ratio: it enhances vehicle handling and agility at low speeds while maintaining driving safety at high speeds. The power assistance is a particular highlight: it not only responds depending on road speed, but also on the current lateral acceleration and the selected AMG DYNAMIC SELECT drive mode. As a result, the driver has a perfect feel for the vehicle thanks to the direct feedback from the road. The standard-fit 3-stage ESP with the "ESP ON", "ESP Sport Handling Mode" and "ESP OFF" functions works in perfect unison with the locking differential and is tuned optimally to the outstanding driving dynamics and safety.

The Mercedes-AMG GT comes as standard with drivetrain damping. A specially tuned damper reduces undesirable rolling motion of the entire drivetrain including the transaxle transmission, thus substantially improving comfort and agility.

The AMG DYNAMIC PLUS package augments dynamism and agility even more. It is available exclusively for the GT S and includes dynamic engine and transmission mounts. The engine and transmission mounts assume an important function in the case of a transaxle design: soft mounts improve comfort since they provide more effective decoupling of noise and vibration. Handling and agility benefit, however, from an overall stiffer mount set-up.

Mercedes-AMG resolves these conflicting objectives using dynamic mounts, which adjust their stiffness continuously, and instantly to the respective driving conditions and handling. The special control electronics in the AMG CHAssIS CONTROLLER, ACC, provide this function. The ACC detects driving situations on the basis of CAN data, is connected to the electronic rear-axle locking differential and thus ensures optimum, balanced driving dynamics. AMG has gone a step further when implementing this technology: the engine and transmission mounts are even actuated independently of each other. The advantage: this innovative solution provides an additional substantial improvement in driving precision and lateral dynamics.

Jochen Hermann, Head of Overall Vehicle Engineering AMG: "The combination of selectively variable mounts and a transaxle drivetrain is unique. Mercedes-AMG is once again promoting leading-edge technology, thus affirming our aspirations in terms of driving performance."

A specific engine application in the DYNAMIC SELECT "RACE" drive mode and in the manual "M" transmission mode makes the GT S even more dynamic. The package also includes tauter suspension tuning thanks to raised spring and damping characteristics, more negative camber at the front axle as well as an adapted sports speed-sensitive steering. Thus the driver benefits from better performance with optimised handling. The performance steering wheel as well as yellow highlights in the instrument cluster round off the AMG DYNAMIC PLUS package.

Excellent deceleration characteristics and high fade resistance come courtesy of the high-performance composite brake system - on the GT with internally ventilated, perforated 360-millimetre brake discs all-round; on the GT S with discs measuring 390 millimetres in diameter at the front, to cope with the higher performance, as well as red brake callipers. A ceramic high-performance composite brake system is available for both models as an option. Its advantages: lower weight, longer service life and even better fade resistance thanks to the ceramic brake discs with a diameter of 402 millimetres at the front and 360 millimetres at the rear.

As standard, the GT is shod in 10-spoke light-alloy wheels, 9 x 19 inch (front) and 11 x 19 inch (rear), with 255/35 R 19 and 295/35 R 19 tyres. On the GT S the dimensions are 9 x 19 inch (front) with 265/35 R 19 tyres and 11 x 20 inch (rear) with 295/30 R 20 tyres. A host of different design and colour variants are available as options for both models, such as the ultralight forged wheels in cross-spoke design, painted black matt, with high-sheen rim flange and fully integrated wheel bolt covers.

In combination with the AMG DYNAMIC PLUS package, specially developed sports tyres are available for the GT S as an option - ideal for aspiring racing drivers on closed-off circuits.

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 kilogrammes - 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.

Vehicle proportions, weight distribution and drive configuration, handling stability, drag, cooling and wind noise: the aerodynamics of the GT fulfil complex requirements. The high-performance vehicle has been developed aerodynamically with one clear objective in mind: high forces must be transferred onto the road without limiting driving dynamics and performance. Thanks to the aerodynamic configuration, critical driving situations can be avoided - such as with a sudden evasive manoeuvre at high speed.

The design of the front apron with A-wing and front splitter not only reduces lift to the desired level, but also helps route air directly to and from the cooling modules. The flow of cooling air from the aerodynamically shaped brake cooling ducts also specifically improves brake performance.

The design of the extensively clad underfloor guarantees optimum exhaust airflow from the oil cooler in the underfloor area and effective airflow for the rear diffuser. As an active component of the aerodynamics, the Mercedes-AMG GT comes with an extendable rear aerofoil that is integrated into the design silhouette. Depending on the drive mode, the aerofoil extends and retracts at various speeds. In combination with the rear diffuser with no leading edges, the lift at the rear axle is reduced to a minimum in the aerodynamically relevant speed range.

On opening the door, the driver is greeted by the AMG start-up screen: an animated GT appears on the TFT display in the instrument cluster. The sportily designed cockpit in carbon fibre look provides information with two classic circular instruments in a 2-tube look and a 198 mph speedometer scale. The performance steering wheel with its three-spoke design sits perfectly in the hand: it comes with aluminium shift paddles, 12 o'clock marking and a steering wheel rim in black nape leather with flattened bottom section. The sports seats in ARTICO man-made leather/black fabric with integral head restraints and AMG lettering provide optimised lateral support when driving dynamically.

The DYNAMIC SELECT Controller, the buttons for the engine start, the 3-stage ESP and, depending on the equipment, the electronic damper control are located on the left in the AMG DRIVE UNIT. The volume control as well as the buttons for the manual transmission drive mode, the ECO start/stop function and, likewise depending on the equipment, the selectable exhaust system are fitted on the right-hand side. The innovative touchpad in the handrest above the COMAND Controller is integrated in front of the E-SELECT selector lever to operate the dual clutch transmission. A free-standing central display is located centrally above the four ventilation outlets. The display boasts a screen diagonal of 17.78 centimetres (7 inches), increasing to 21.33 centimetres (8.4 inches) if COMAND Online is specified. The driver operates the seat heating, PARKTRONIC, the hazard warning lights and, depending on the equipment, the extendable rear aerofoil using the buttons in the top control panel in the roof frame.

As an alternative to the standard-fit Interior Silver Chrome package, the customer can choose from various other packages. Carbon-fibre trim elements are available in a choice of matt and high-gloss finish. Highlights include the trim in matt silver fibreglass and the Interior Black Diamond package, all offered for the first time: here the ventilation outlets, the frame of the centre console and the trim strips in the door armrests come in a sophisticated high-gloss black finish, with its surprising 3D look. The "black diamond" method uses the chemical CVD (chemical vapour deposition) gas phase process to deposit a precious metal on a high-sheen chrome surface at temperatures of 1000°C. The metal reacts with the surface to form a layer that is highly scratch-resistant and has a high adhesive strength.

The superb everyday practicality of the Mercedes-AMG GT is also expressed in the airy feeling of spaciousness. In addition, the good all-round visibility and the high headroom demonstrate that sporty dynamism and comfort on long journeys are not mutually exclusive - not necessarily a given in this segment. A large stowage compartment in the centre armrest, a centrally positioned twin cup holder and a large, easily accessible glove compartment are further evidence of the outstanding everyday suitability of the GT. The luggage compartment capacity of 350 litres will hold two golf bags either lengthways or crossways. The large boot lid makes loading easy; an integral retractable luggage cover comes as standard. The cross strut made out of aluminium behind the seats prevents luggage from sliding forward as the vehicle brakes.
