Toyota Presents World Debut of Toyota GR Supra GT4 Concept at 2019 Geneva Motor Show

- Promoting "ever-better-cars" through customer, privateer motorsports -

Toyota proudly presents the world debut of the new Toyota GR Supra GT4 Concept at the 2019 Geneva Motor Show, held from March 7 to 17th, 2019, in Geneva, Switzerland.

Under Toyota's global initiative of "ever-better-cars", TOYOTA GAZOO Racing aims to further enhance customer motorsports by developing an environment where motorsports fans can more readily participate and enjoy race activities. In addition, based on the feedback acquired through participation in motorspors, TOYOTA GAZOO Racing will look at how to implement improvements in future car development.

The GR Supra GT4 Concept was developed as a racing study model based on the GR Supra, TOYOTA GAZOO Racing's first global model. The model was developed by Toyota Motorsport GmbH, Toyota's motorsports foothold in Europe, to explore the possibility of using the GR Supra in customer motorsports such as privateer racing.

GT4 is one of the world's fastest-growing motorsports categories, with national and regional competitions in Europe, North America, Asia and Oceania. Customers can participate in various races around the world by purchasing commercially available racing-specification cars that have been specially tuned for performance. The commercial Toyota Supra comes standard with high performance specifications such as a light-weight body, a low-center of gravity, and high rigidity. These specifications make it an ideal vehicle to serve as the base for customer motorsports.

The GR Supra GT4 Concept is even more light-weight than the commercial Toyota Supra, and is equipped with race specific parts such as roll cage, suspension, brake and rear-wings.

Supra has taken part and has played an active role historically in various motor sports worldwide and the all-new Supra will continue this tradition. For 2019, in addition to NASCAR Exfinity Series, Supra will take part in the Nurburgring 24 Endurance Race (plan to take part in SP8T). In 2020, Toyota Supra will also take part in the SUPER GT, GT500 Class.

Moving forward, TOYOTA GAZOO Racing will continue to explore and expand the involvement of the ToyotaSupra in motorsports as well as leverage the learning and know-how garnered as it looks to develop "ever-better-cars".

Developed for potential motorsport role

- World debut of the new GR Supra GT4 Concept at the 2019 Geneva Motor Show

- Designed and engineered to comply with international GT4 competition regulations

- The GR Supra GT4 Concept explores how the new Supra could be used as the basis for an affordable and competitive car for privateer racers

Toyota presents the world debut of the new GR Supra GT4 Concept at the 2019 Geneva Motor Show on 5 March. 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.

The concept model, developed by TOYOTA GAZOO Racing, is instantly recognisable as a Supra and maintains the road car’s low, muscular shape, but with increased length and lowered height. A specially-designed front diffuser and rear wing have been added to the GR Supra GT4 Concept to improve airflow around the chassis, reducing drag and optimising downforce. Both items are constructed using composites made from natural fibres such as hemp and flax, replacing the traditional carbon fibre in order to reduce the impact on the environment. Original alloy wheels have been replaced by five-hole OZ 11 x 18in racing wheels.

The MacPherson strut front and multilink rear suspension design is carried over, but with the addition of competition springs, shock absorbers and anti-roll bars. The high-power deceleration required for racing is provided by high-performance Brembo brakes.

Under the bonnet, the GR Supra GT4 Concept retains the 3.0-litre straight-six-cylinder petrol engine with single twin scroll turbocharger, coupled to an automatic transmission. Performance is increased with help from a motorsport-grade ECU and bespoke wiring looms. There are also motorsport-specification drive shafts and limited slip differential.

The stripped-out cabin is fitted with a high-strength roll cage and FIA-standard fire extinguisher and OMP racing seat. The concept car is also equipped with a motorsport-specific fuel tank and a fast refuelling system.

GT4 is one of the world’s fastest-growing motorsports categories, with national and regional competitions in Europe, North America, Asia and Oceania. Established since 2006 and sanctioned by the FIA, it is designed to be a value-for-money series for both professional and amateur racers, and a potential stepping-stone to GT3 competition.

TOYOTA GAZOO Racing will evaluate the interest shown by potential customers in the Supra GT4 Concept before deciding on future development of the vehicle.
