2018 Mercedes AMG GT Family – Video
The AMG GT is the second sports car to be developed entirely in-house by Mercedes-AMG. In less than three years, it has evolved into a family which comprises eight models to date. It embodies the essence of the performance and sports car brand. The front mid-engine concept with transaxle dual-clutch transmission at the rear axle and the intelligent aluminium lightweight construction form the basis for a highly dynamic driving experience. The AMG GT family offers plenty of choice: Coupé and Roadster, four power ratings for the 4.0-litre V8 biturbo engine, the various applications of the engine as well as the optimally configured transmission, different variants with regard to suspension, tyres and aerodynamics, distinctive items of equipment, numerous technical innovations and the comprehensive range of options enable extremely individual customisation of the respective vehicles. The family further includes two customer sport racing cars for professional use in international GT3 and GT4 racing series and the AMG GT Concept, which offers a foretaste of the next member of the AMG GT family in the guise of the first four-door vehicle to be added to the range.
The combination of aluminium spaceframe, V8 biturbo engine with dry sump lubrication, seven-speed dual-clutch transmission, differential lock, sports suspension with aluminium double wishbone axles and the low kerb weight provides for the ultimate in Driving Performance.
“In under three years, the second vehicle to be developed by us entirely in-house has grown into a family offering a highly dynamic driving experience in a variety of forms,” observes Tobias Moers, CEO of Mercedes-AMG GmbH.
The basic layout with front mid-engine concept and transmission in transaxle configuration at the rear axle enables an advantageous slightly rear-biased weight distribution. In conjunction with the vehicle’s low centre of gravity, this translates into extremely agile handling and permits high cornering speeds. The AMG 4.0-litre V8 biturbo engine delivers ample power right from the low rev range and enables outstanding performance. At the same time, the two-seater is a straightforward, comfortable and reliable companion for everyday motoring thanks to its easily accessible luggage compartment, a high level of comfort on long journeys and the extensive Mercedes-Benz Intelligent Drive assistance systems.
There is a choice of four output and torque ratings: The entry-level AMG GT and AMG GT Roadster models generate 350 kW (476 hp) and peak torque of 630 Nm. The AMG GT S delivers an output of 384 kW (522 hp) and 670 Nm of torque. The C variants of the Coupé and Roadster define the next level, each with an output of 410 kW (557 hp) and peak torque of 680 Nm. The top of the line is the AMG GT R with 430 kW (585 hp) and 700 Nm of torque. The increase in performance for the AMG GT C; AMG GT R and AMG GT C Roadster has been achieved with the aid of new turbochargers with a modified compressor design, higher boost pressure and a smaller wastegate aneroid capsule. In addition, the exhaust ports have been optimised and the compression ratio adapted.
On all variants, the two turbochargers of the V8 engine are positioned not in the customary manner on the outside of the cylinder banks, but inside the “V” between the banks. Advantages of the “hot inside V”: a compact engine design, spontaneous response from the turbochargers and low exhaust gas emissions thanks to optimum air flow for the close-coupled catalytic converters.
The first gear of the dual-clutch transmission has a higher ratio on the AMG GT C, AMG GT C Roadster and AMG GT R. Seventh gear and the final drive have lower ratios to allow a more agile acceleration experience overall and very spontaneous response to fast accelerator pedal movements. Shift performance and response time have also been taken to a whole new level.
