Toyota GR GT V8 Hybrid Supercar : Full Specs, Features, Performance & Launch Details

The Toyota GR GT represents the most significant moment in Toyota’s high-performance heritage since the legendary Lexus LFA in 2010. Unveiled on December 5, 2025, at the company’s Woven City Test Facility in Susono, Shizuoka Prefecture, Japan, the GR GT is Toyota’s first true supercar developed entirely under the GAZOO Racing (GR) brand. Positioned as a road-legal race car, the GR GT embodies Toyota’s commitment to preserving and passing on the “secret sauce of car-making” to the next generation of engineers and designers.

This flagship model represents an unprecedented engineering achievement for Toyota, the first production vehicle to feature an all-aluminum body frame, a newly developed 4.0-liter twin-turbocharged V8 engine and a sophisticated hybrid powertrain that pushes the boundaries of what a Japanese sports car can achieve.

Exterior Design & Aerodynamics

The GR GT’s exterior design follows an unconventional “aerodynamics-first” philosophy that sets it apart from traditional supercar development approaches. Unlike traditional automotive design where aerodynamics are considered after styling finalization, the GR GT’s design process is completely reversed. Aerodynamics engineers, working with experience from the FIA ​​World Endurance Championship (WEC), first set ideal aerodynamic performance targets, and only then did the designers shape the exterior to meet those targets.

The result is a low, wide and aggressive-looking coupe design that prioritizes function over traditional aesthetics. The car is 4,820 mm (189.7 inches) long, 2,000 mm (78.7 inches) wide and just 1,195 mm (47 inches) tall, with a 2,725 mm (107.2-inch) wheelbase, dimensions that place it firmly in the hypercar realm alongside machines like the Lamborghini Revuelto.

The design features numerous aerodynamic elements that serve the dual purposes of cooling and performance optimization. A large, vented bonnet extends outwards towards the driver, reminiscent of classic race cars and the Mercedes-Benz SLS AMG design language. Large front air intakes provide cooling air to the engine and braking system, while dedicated NACA ducts on the hood extract heat. Flat fenders are sculpted to direct airflow around the wheels, with rear wheel well vents managing turbulence. The glasshouse is tight and Mazda RX-7-esque in appearance, while the rear gets a subtle ducktail spoiler and full-width LED taillights.

At the rear, a dual-channel diffuser with integrated quad exhaust tips is engineered for maximum downforce and stability. Around the car, every crease, opening and panel has been shaped with one priority in mind, improving cooling, reducing drag and ensuring the GR GT remains stable at high speeds.

Dimensions and Weight

Toyota has kept the GR GT’s weight under 1,750 kg by relying heavily on lightweight materials such as aluminum and carbon fiber reinforced plastic (CFRP). The car uses an all-aluminum body frame, a first for Toyota on a production model, which provides high rigidity while keeping overall weight low. The structure is constructed from large aluminum castings supported by strategically placed aluminum extrusions and advanced joining techniques, which work together to maximize strength without adding unnecessary weight. The exterior panels use a combination of aluminum and CFRP to strike the right balance between durability and lightweight construction.

To improve handling, Toyota has also focused on ideal weight distribution. The GR GT achieves a 45:55 front-to-rear balance thanks to a rear-transaxle layout and careful placement of heavy components such as the battery, fuel tank and related hardware. This setup makes the car more stable, predictable, and responsive on the road or track.

Engine and Powertrain Specifications

Engine: Newly Developed 4.0-Liter Twin-Turbo V8

The GR GT’s engine is Toyota Motor Corporation’s first twin-turbocharged V8 engine to be fitted to a production vehicle, a historic milestone for the company. Developed on a “completely compact and lightweight” design philosophy, the engine achieves an exceptionally low center of gravity, which is important for the vehicle’s balanced handling characteristics.

The engine uses a short-stroke layout (87.5 mm bore × 83.1 mm stroke), which creates an under-square design that helps reduce the overall height of the engine. This lower profile plays a large role in achieving the GR GT’s low center of gravity, which is essential for sharp handling and balanced weight distribution. In addition, a “hot-V” setup places a turbocharger between each bank of cylinders. This position shortens the distance the exhaust gases travel, reducing turbo lag and giving the engine a quick, responsive feel. It also helps keep the engine package compact, another key advantage for performance-focused packaging.

Toyota further improves the car’s handling dynamics through a dry-sump lubrication system combined with an unusually thin oil pan. This setup allows the engine to sit further down in the chassis, which directly contributes to the GR GT’s exceptionally low center of gravity, vital for precise cornering and a strong sense of driver connection.

Hybrid Powertrain and Performance Output

The GR GT uses a transaxle-integrated single-motor hybrid system that couples its V8 engine with an electric motor mounted before the transmission. This setup adds torque during hard acceleration and between gear changes, eliminating the brief drop in power typically experienced when the car shifts. The electric motor’s immediate response ensures smooth, strong acceleration and improves overall drivability.

A separate motor-generator is housed in the trunk area above the transmission, working alongside the engine to deliver consistent performance across the rev range. Together, the system is engineered to provide seamless power delivery, quick throttle response and a more connected driving feel.

Toyota also notes that the current performance figures are still subject to development and improvement as final tuning continues ahead of the GR GT’s planned 2027 launch.

Transmission and Drivetrain

Drivetrain : Front-engine, rear-wheel drive

The GR GT is equipped with a newly developed 8-speed automatic transmission that uses a wet-start clutch instead of a conventional torque converter. This setup functions similarly to the high-performance gearbox found in Mercedes-AMG models, allowing the transmission to deliver extremely fast shifts while remaining lighter and smoother than a dual-clutch system.

To enhance handling, the transmission gets a mechanical limited-slip differential that ensures precise torque distribution between the rear wheels. Power passes from the engine to the rear transaxle via a carbon-fiber-reinforced plastic (CFRP) torque tube, which helps reduce weight while keeping the drivetrain structurally rigid.

One of the more unique engineering elements is the bevel gear arrangement in the rear transaxle. This system reverses the direction of power flow, an idea borrowed from the all-wheel-drive layout but redesigned specifically for the GR GT’s front-engine, rear-wheel-drive architecture. By doing so, Toyota shortens the wheelbase and improves overall weight distribution, resulting in a more compact and better-balanced performance package.

Suspension, Braking, and Tire Systems

Suspension

The GR GT uses an all-new, low-mounted double-wishbone suspension system that Toyota developed from scratch. Its geometry and behavior were shaped by a combination of advanced simulator testing and extensive real-world evaluation with professional drivers. The goal was to achieve a suspension that was linear, predictable and confident in every situation, whether you were cruising down the street or pushing the car to its absolute limits on the racetrack.

Toyota worked closely with GAZOO Racing’s pro drivers, repeatedly fine-tuning the setup based on feedback from both virtual and physical testing. Development took place at several circuits, including Fuji Speedway and the Nürburgring, ensuring that the suspension delivered sharp response, excellent control and consistent performance in the most demanding environments.

Braking System

The GR GT is equipped with Brembo carbon-ceramic disc brakes on all four wheels, which deliver powerful, consistent stopping performance while keeping weight to a minimum. Toyota has fine-tuned the braking feel with input from professional drivers, ensuring that the system delivers predictable, responsive and confident handling in everything from everyday driving to high-speed track use.

The car features an advanced vehicle stability control system with multi-stage adjustability. Drivers can select different levels of driving force and braking intervention based on their skill level, road conditions or weather. The system has been refined through experience at demanding events such as GAZOO Racing’s Nürburgring 24-hour race, resulting in a setup that offers both precision and flexibility for a wide range of driving scenarios.

Tires

The Michelin Pilot Sport Cup 2 tires in the GR GT have been developed specifically for the car through a partnership between Toyota and Michelin. Using simulator analysis and extensive real-world testing, engineers and professional drivers worked together to fine-tune the tires and suspension as a coherent system. The development program covered a wide range of road surfaces and famous test circuits, ensuring that the final setup provides maximum grip, stability and confidence, whether on the street or the track.

Interior Design and Features

The interior of the GR GT is built following a pure driver-first philosophy, with ergonomics, visibility and intuitive control placement taking precedence over all else. Every element of the cabin has been designed to create a driving position that is equally functional and useful for professional racers on the track and everyday enthusiasts on the road.

Interior Layout and Materials

Inside the cabin, the GR GT offers a minimalist yet purposeful layout. The flat-bottom steering wheel, oversized paddle shifters, clean horizontal dashboard and tall, structured centre console create a focused, cockpit-like environment. Red leather and Alcantara are used throughout the cabin, giving it a premium look and helping to maintain a performance-oriented feel.

A key engineering goal was to align the driver’s seating position with the car’s centre of gravity to enhance the feeling of connection and control. Extensive ergonomic studies and constant feedback from professional drivers were undertaken to achieve this, ensuring that the ultimate seating position enhances stability, confidence and comfort.

Instrument Cluster and Controls

The digital instrument cluster features custom graphics designed for clarity during high-speed driving. It includes prominent shift indicators, gear position displays and strategically placed shift lights for quick visibility. Toyota has refined the size and layout of the display through repeated testing and input from professional drivers to ensure essential information can be read at a glance.

All key driving switches are positioned close to the steering wheel and are shaped for intuitive use, helping to keep the driver’s attention on the road. The layout maintains good outward visibility while providing a protective, cockpit-like feel suitable for both track sessions and daily driving.

Center Console and Technology

The center console integrates a large infotainment screen but retains physical toggle switches for essential functions like climate control. This avoids deep menu navigation and is consistent with the vehicle’s race-car-inspired simplicity, where quick tactile inputs are more important than layered touchscreen commands.

A “Boost” mode visible on the console hints at multiple performance settings that adjust how the engine and electric motor work together, allowing the driver to fine-tune power delivery for different driving scenarios.

Sound Engineering

The GR GT retains the unmistakable character of the twin-turbo V8, delivering a sound that is emotional and deeply connected to the car’s performance. Toyota has developed the engine note around two key ideas: creating a sound that helps the driver feel in tune with the car, and shaping acoustics that clearly reflect changes in engine load, temperature and overall condition.

The exhaust system is precision-engineered so that every phase of driving, from gentle throttle inputs to full-boost acceleration, produces a sound that reflects what the car is doing mechanically. This careful tuning aligns with GAZOO Racing’s philosophy of building cars that engage all the senses, reinforcing a strong, intuitive connection between driver, engine and road.

GR GT3 Race Car Variant

Building on the GR GT platform, GAZOO Racing has also developed the GR GT3, an FIA GT3-specification race car. It maintains the same principles of a low center of gravity, lightweight high-rigidity construction and optimized aerodynamics, aimed at professional and gentleman drivers seeking competitive performance.
