- Supra concept at Geneva for new series
- Read-to-race car for GT4 amateur racers
- Regulations will balance the racing code
GENEVA, Switzerland – Toyota will debut its GR Supra GT4 concept at the 2019 edition of the annual world auto show here on March 5. Awesome, hey?
The car, Toyota says, is a ”design and engineering study” that explores how the fifth generation of the Supra sport car might develop for international GT4 racing and be affordable for private teams – in line, the automaker says, ”with our global support for grassroots motorsport”.
The road-going Toyota GR Supra is said to have qualities that qualify it for GT4 racing: perfect chassis balance, two-seat cabin, rigid but light body, rear-wheel drive, and a very low centre of gravity.
Those attributes, plus a short wheelbase / wide track, are said to have created an ”ideal” ratio for stability and agility – valuable assets, Toyota says, in a racing series in which the regulations use a balance of performance calculation (adjusting weight according to engine power) to ensure even competition.
The concept model, developed by Toyota Gazoo Racing (yes, the guys who back Toyota SA in its annual Dakar endeavour), is instantly recognisable as a Supra and has the road car’s low, muscular, shape though longer and lower.
A front diffuser and rear wing have been added to the pictured GR Supra GT4 concept to improve airflow and downforce. Each, Toyota says, is made natural fibres such as hemp and flax to ”help the environment”.
The package rides on five-hole OZ 11×18” race wheel rims.
The Macpherson strut front and multilink rear suspension design is carried over but with competition springs, shock-absorbers and anti-roll bars; Brembo has been entrusted with hard braking.
The GR’s power will come from a three-litre straight-six, turbocharged petrol engine and delivered through an automatic transmission. There are also motorsport-spec drive shafts and limited-slip differential.
The stripped cabin has a roll cage, fire-extinguisher and race seat; other changes include a motorsport-spec fuel tank and a fast-refueling system.
For those not motorsport savvy the GT4 is one of the world’s fastest-growing motorsport categories and has since 2006 included National and Regional meetings across Europe, North America, Asia and Oceania as a ”value-for-money” series for professional and amateur drivers.
It’s also seen as a rung on the racing ladder to GT3 competition.
- Toyota Gazoo Racing will evaluate interest in the Supra GT4 concept before saying yay or nay to full production. Demand in Europe has been high – 900 buyers have signed orders.
