Toyota Gazoo Racing has announced that it will
commence sales of the GR Supra GT4 in Europe from March 2020, with the race car
set to be offered to customers teams in North America later on in August,
followed by those in Japan/Asia in October.
The Supra GT4 is developed and produced by Toyota
Motorsport GmbH (TMG), providing those looking to participate in motorsports
with a more accessible and affordable means to do so. The cars in the
GT4 class are much closer to the road cars they are based on, although they
still get their fair share of modifications.
In the case of the Supra GT4, the 3.0 litre
turbocharged straight-six engine has been retuned to produce 429 hp and 650 Nm,
which is 94 hp and 150 Nm more than what the road car offers. The mill is mated
to a race-ready seven-speed automatic (with paddle shifters), GKN Motorsport
driveshaft and a mechanical limited-slip differential that drives the rear
wheels. There’s also a Magneti Marelli ECU, ATL FT3 fuel cell, Akrapovic
exhaust system for better acoustics, while Ravenol provides first-fill
lubricants.
Aside from tinkering with what’s under the bonnet,
the race car also employs KW adjustable dampers for the stock suspension setup
of McPherson struts at the front, and multi-link rear. For stopping power, the
car is fitted with a Brembo brake system consisting of 390 mm steel discs with
six-piston calipers at the front, and 355 mm rear discs with four-piston
calipers. The Supra GT4 runs on 305/660 series Pirelli tyres wrapped around
18-inch OZ wheels.
To ensure compliance with safety requirements, the
interior gets a high-strength roll cage and an FIA-standard OMP racing seat
with six-point harness. Other add-ons include an eight-inch Bosch DDU10 display
and data logger, a racing steering wheel and carbon-fibre panels that replace
those that have been removed to save weight. In fact, the largely barren cabin, natural fiber
composite front splitter and rear wing, as well as the rest of the car, only
adds up to an overall weight of 1,350 kg, which is around 200 kg less than the
road-going GR Supra.
If you’re interested, the asking price is 175,000
euros excluding taxes, customs fees and logistic fees. The contact
company for each region is TMG if you live in Europe, TRD USA for North
America, and Toyota Customizing & Development for Japan/Asia.
