Toyota GAZOO Racing ran the GR GT and the GR GT3 at WeatherTech Raceway Laguna Seca. First public, uncamouflaged hot laps in North America. Friday, August 14, 12:55 to 1:10 p.m. Saturday, August 15, 5:55 to 6:10 p.m. Both cars are still prototypes. The road car is targeting 641 horsepower or more. There is no price. Launch is “around 2027.” GAZOO Racing’s August 11 release is the source.
641 horsepower. Still a target.
The GR GT is the road car. Two seats. Front-engine, rear-drive. Toyota’s first all-aluminum body frame. Body panels mix aluminum and carbon-fiber reinforced plastic. A newly developed 4.0-liter twin-turbo V8 and a single electric motor in the rear transaxle. TGR calls this Toyota’s first V8 for a production car. TGR’s December 5, 2025 world premiere listed the numbers as development targets, in-house measurements. The August 11 Monterey sheet repeats them in U.S. units.
Official figures, still labeled prototype development targets:
- Maximum system output: 641 hp or greater (650 PS or greater)
- Maximum system torque: 627 lb-ft or greater (850 Nm or greater)
- 3,998 cc V8, twin-turbo, dry-sump, hot-V, 87.5 × 83.1 mm bore and stroke
- Transaxle-integrated single-motor hybrid
- Newly developed 8-speed automatic, wet-start clutch, no torque converter
- Carbon-fiber torque tube, mechanical limited-slip differential
- Vehicle weight: 1,750 kg or lower
- Front/rear weight distribution: 45/55
- Top speed: 320 km/h or greater
- Double wishbone, coil springs, forged aluminum arms, front and rear
- Carbon-ceramic discs, Brembo
- Michelin Pilot Sport Cup 2 tires developed for the car: 265/35ZR20 front, 325/30ZR20 rear
- Length 4,820 mm, width 2,000 mm, height 1,195 mm, wheelbase 2,725 mm
The motor sits in front of the gearbox and is there to cover the lag on throttle and on shifts. That is TGR’s line, not a dyno sheet. Toyota still will not publish a price. The December kit said further details would come as they become available. Eight months later, the Monterey release did not add one.
The race car is the point
The GR GT3 is the FIA GT3 car. Same 4.0-liter twin-turbo V8. Many of the structural engine parts are shared. The road car’s eight-speed automatic is gone. The Monterey release says a purpose-built racing transmission. TGR published almost no other GT3 numbers. No power. No weight. No price for a customer car.
What is official:
- Length 4,785 mm, width 2,050 mm, height 1,090 mm
- 3,998 cc V8, twin-turbo
- Front-engine, rear-wheel drive
- Built to FIA GT3 rules
- Aluminum space-frame and double-wishbone layout shared in concept with the road car
TGR said the two were developed in tandem. The road car is supposed to bring “true links to motorsports to the road.” That is the marketing line. The hardware link is the V8, the aluminum frame, and the drivers who signed both cars. Testing ran at Toyota Technical Center Shimoyama, Fuji Speedway, and the Nürburgring. The December kit also says public-road work on the GR GT. Development is not finished. The cars say so in the fine print.
Two sessions. Two drivers.
Jack Hawksworth has been a GR GT3 development driver. Tatsuya Kataoka is another GR development driver. They were scheduled for both Laguna Seca windows. Japanese racing cars are the featured marque at this year’s Rolex Monterey Motorsports Reunion. Toyota picked the week on purpose.
Static displays sat in the Laguna Seca pit garages from Wednesday, August 12 through Saturday, August 15. The Quail, a Motorsports Gathering, got a look on Friday the 14th. Both are ticketed. The August 11 release says so.
The cars that lapped Laguna Seca are the same class of prototype TGR put on a stage in Woven City on December 5, 2025. Development is continuing. The launch window is still “around 2027.” No MSRP. No U.S. allocation. No production volume. If you want a number Toyota will stand behind, it is 641 horsepower or greater, and even that is a target.
