At first glance, the GR GT’s silhouette looks like something straight out of the concept garage in Gran Turismo 7. But this is neither a video game creation nor a design study. The GR GT is a fully production-ready, road-legal sports car developed by Toyota’s GAZOO Racing (GR) performance division—built for a new generation of enthusiasts with serious racing expectations.
The GR GT has been developed alongside the GR GT3 race car and the Lexus LFA Concept, forming a three-pronged, high-performance strategy. Led by Toyota Motor Corporation Chairman Akio Toyoda and his “driver-first” philosophy, this approach highlights Toyota’s commitment to performance across internal combustion, hybrid, and electric powertrains.
More than just a flagship model, the GR GT represents Toyota’s vision for the future of driving excitement. It serves as a road-going race car and a rolling showcase of how the brand intends to preserve, refine, and evolve its motorsports-driven vehicle development philosophy.
The GR GT is built on Toyota’s first all-aluminum body frame, engineered to deliver low mass without compromising structural rigidity. The primary structure relies on aluminum castings, complemented by aluminum extrusions and advanced joining techniques to maximize strength and efficiency.

To further reduce weight, Toyota incorporates carbon fiber–reinforced plastic (CFRP) panels, including the hood, roof, and rear hatch frame. As a result, the GR GT targets a curb weight of 3,858 pounds or less, with an ideal 45:55 front-to-rear weight distribution.
Achieving a low center of gravity was a core engineering priority. Designers lowered the overall vehicle height, the driver’s seating position, and the mounting points of key components—most notably the 4.0-liter twin-turbo V-8. The engine features a dry-sump lubrication system and a flattened oil pan, allowing it to sit lower in the chassis.
Engineers also focused on centralizing mass within the wheelbase. The engine is positioned behind the front axle line, while the cabin is pushed forward of the rear wheels. This layout effectively classifies the GR GT as a front-midship sports car, optimizing balance, handling, and overall driving dynamics.
The GR GT features a sophisticated suspension setup with unequal-length A-arms front and rear, constructed from forged aluminum and mounted low to enhance stability and handling. Development began early with input from professional racing drivers, supported by extensive simulator-based testing to fine-tune performance.
Grip comes from Michelin Pilot Sport Cup 2 tires, developed specifically for the GR GT, while braking performance is enhanced through the use of Brembo carbon brake discs.

Powertrain
The GR GT employs a high-performance hybrid powertrain that combines a newly developed 4.0-liter twin-turbo V-8 with a single electric motor mounted at the front of the transaxle. Toyota’s GAZOO Racing engineers are targeting a combined system output of at least 641 horsepower and 627 lb-ft of torque, delivering both instant response and sustained high-speed performance.
Power is delivered through an axle enclosed in a carbon fiber–reinforced plastic (CFRP) torque tube to a rear-mounted transaxle. This transaxle houses an eight-speed automatic transmission that replaces a traditional torque converter with a wet-start clutch for faster, more direct response. A motor-generator supports the system by assisting during acceleration and smoothing gear changes.

To keep the wheelbase compact, engineers use a conical gear arrangement that reverses power flow at the rear of the transaxle, routing it forward through a mechanical limited-slip differential before sending torque to the rear wheels via half-shafts. Toyota says the transmission is being engineered for world-class shift speed while still allowing deliberate, manual-style control—even in automatic mode.
With 627 lb-ft of torque, rear-wheel drive, a rear-biased layout, and a mechanical LSD, the GR GT promises engaging performance—capable of controlled burnouts, drifts, and track-ready dynamics on demand.
Aerodynamics and Exterior Design
The GR GT’s design follows an “aerodynamics-first” philosophy, reversing the traditional approach of styling before engineering. Aerodynamic and cooling requirements were established before any exterior sketches, with engineers and designers working in close collaboration from the start.
With a target top speed of 199 mph or more, precise airflow management is critical. By allowing function to shape form, the GR GT achieves a sleek, low-drag profile that cuts cleanly through the air—free from unnecessary lines and focused entirely on performance
