Toyota presents the world debut of the new GR Supra GT4 Concept. It is a design and engineering study that explores how the newly launched fifth generation of the legendary Supra sports car might be developed as a competitive machine for international GT4 racing, accessible and affordable for privateer racers and small teams in line with Toyota’s worldwide support for grass-roots motorsport.The road-going Toyota GR Supra has essential qualities that make it an attractive proposition for GT4 racing, with its perfectly balanced chassis, two-seater cabin, highly rigid and light weight body, rear-wheel drive and very low centre of gravity. The combination of the short wheelbase and wide track gives it an ideal 1.55 “golden ratio” for excellent stability and agility, which are valuable assets in a series where the regulations use a balance of performance calculation (adjusting weight according to engine power) to ensure even competition across the field.
Highlights from the 2022 motorsport season for Audi Sport customer racing with worldwide success for the Audi RS 3 LMS touring car and the three GT models of the R8 LMS GT2, GT3 and GT4.
The GT4 race car, which is directly derived from the production model with about 60 percent carry-over parts and, like the road-going version, is being produced at Böllinger Höfe at the Neckarsulm location is exclusively intended for privateer drivers. Since 2018, the previous model has clinched as many as 17 titles worldwide in racing, and now the freshly refined version has arrived. With visual cues taken directly from the production model, the new race car impresses with driving dynamics having been enhanced once again. The 5.2-liter V10 engine, delivering up to 364 kW (495 hp) as specified by the regulations, powers the race car via a seven-speed dual-clutch transmission.
The naturally aspirated flat-six engine, familiar from the 911 GT3 Cup racing car and the 911 GT3 series production model, forms the centrepiece of a sports car that has been designed for maximum driving pleasure. The engine revs as high as 9,000 rpm. Compared to the 718 Cayman GT4, the 718 Cayman GT4 RS has an extra 80 PS, resulting in a weight-to-power ratio of 2.83 kg/PS. Maximum torque has been increased from 430 to 450 Nm.Among the striking features of the new, top-of-the-range 718 are the process air intakes behind the driver and passenger windows. The 718 Cayman normally has small side windows here. The new air intakes improve both the intake airflow and, at the same time, create a thrilling intake noise right next to the occupants' ears. The characteristic air intakes in front of the rear wheels have been retained and are used for engine cooling.
The Toyota GR Supra has made a remarkable impact, affirming its status as a sports car in its purest form, designed and engineered for the joy of driving. As the first global model to be developed by Toyota Gazoo Racing, it has drawn on Toyota’s sports car heritage while exploring new horizons of handling and performance.Now the range is being extended in the UK for the first time with the established 3.0-litre six-cylinder turbocharged engine being joined by a new 2.0-litre four-cylinder turbo unit.The new 2.0-litre engine widens GR Supra’s market appeal and, being lighter and more compact than the 3.0-litre unit, improves the car’s inertia characteristics and chassis balance for even sharper handling.Where weight is concerned, the GR Supra 2.0 weighs 100kg less than its 3.0-litre equivalent, a saving that further strengthens the car’s dynamic performance. The engine’s shorter length means its mass is located closer to the centre of the car, supporting an ideal front/rear balance and better inertia characteristics.
