Toyota’s GR Supra GT4 Racecar Ups the Ante in the Popular Racing Class
PLANO, Texas (November 5, 2019) – The GR Supra GT4 at Toyota’s 2019 Specialty Equipment Market Association (SEMA) Show booth offers a look at what will surely be the next game changer in the popular GT4 class.
“Toyota’s worldwide support of motorsports inspired the design of the GR Supra GT4. It also serves as an engineering study to see how the fifth-generation Supra might be developed for international GT4 competition. This rapidly growing FIA-sanctioned class is particularly interesting as it accommodates privateers and small race teams,” said Tyler Gibbs, General Manager at Toyota Racing Development.
The 2020 GR Supra, with its perfectly balanced chassis, stiff yet lightweight sport coupe body, rear-wheel drive and low center of gravity, already has qualities desired in a GT4 racecar. Its short wheel base and wide track width offer excellent stability and agility, perhaps the most important attribute in a road racing car.
TOYOTA GAZOO Racing created the GR Supra GT4 which benefits from a specially-designed front diffuser and rear wing that lend to improved airflow around the chassis. These components are made using materials derived from natural fibers like hemp and flax instead of carbon fiber to reduce its environmental impact.
Under the hood, the factory B58 engine and transmission carry over from the road-going model. A motorsport ECU and wiring harness permit greater engine calibration flexibility for improved performance. Motorsport-specific axles and limited-slip differential distribute power to the rear wheels.
KW Automotive Competition coilovers and Toyota Motorsports GmbH (TMG) anti-roll bars replace the factory pieces to improve handling. High-performance Brembo 6-piston racing calipers with 390x32mm two-piece rotors in front and 4-piston racing calipers with 355x32mm two-piece rotors at the rear offer improved heat capacity and stopping performance that is essential for competition. Strong and lightweight OZ racing wheels improve handling and feedback, while Pirelli 305/660×18 racing slicks keep the GT4 planted to the tarmac.
The stripped-down interior features an OMP racing seat placed within the latticework of a high-strength FIA-compliant cage equipped with a regulation fire extinguisher. A TMG carbon-fiber steering wheel positions a Bosch DDU 10 display within easy view of the driver.
TOYOTA GAZOO Racing confirms that it will launch the GR Supra GT4 as a racecar in 2020. In this highly competitive class, a GR Supra GT4 will shake up the competition and foster growth and interest among privateer racers.
The GR Supra GT4—along with other Toyota specialty vehicles—can be found in the Toyota display booth (#24800) in Central Hall and on the Patio Annex of the Las Vegas Convention Center, November 5 – November 8, 2019.
