TOYOTA GAZOO Racing (TGR) has lifted the covers on two highly anticipated prototypes – the GR GT and GR GT3 – marking a major leap forward for the brand’s performance and motorsport ambitions. Revealed to the public for the first time, the pair represent Toyota’s most advanced interpretation yet of its “driver-first” development philosophy and showcase technologies never before used in a Toyota production car.
Both vehicles are being positioned as future flagships for Toyota’s performance portfolio. They embody the same pioneering ambition that produced icons such as the Toyota 2000GT and the Lexus LFA, while pushing TGR’s motorsport-to-road-car development ethos into a new era. With world-class engineering, a complete rethink of aerodynamics and packaging, and a focus on motorsport-honed performance, the GR GT and GR GT3 are set to become two of the most important models TGR has ever produced.
A New Generation of Flagship Performance Cars
From the outset, the GR GT and GR GT3 were developed around three core principles that define TGR’s approach to creating “ever-better” cars:
These principles were applied consistently from concept stage through to prototype engineering, resulting in two vehicles that represent a complete rethinking of Toyota’s high-performance architecture.
The models are also the first to feature Toyota’s all-aluminium body frame, a significant milestone that demonstrates the brand’s commitment to lighter, stronger and more responsive performance cars. Both cars are powered by a completely new 4.0-litre V8 twin-turbo engine, which has been engineered to be exceptionally compact and low in height, enabling a packaging layout rarely seen in road-legal vehicles.
Development was led directly by TMC Chairman Akio Toyoda – Master Driver “Morizo” – together with top professional drivers, gentleman racers including Daisuke Toyoda, and Toyota’s elite in-house evaluation team. This hands-on collaboration between engineering and racing talent ensured that real motorsport expertise informed each phase of the cars’ development.
GR GT: A Road-Legal Race Car for Purists
The GR GT is Toyota’s new flagship sports car, engineered from the ground up as a road-legal race car. Rather than adapting a road car for track capability, TGR has effectively taken a pure competition mindset and applied it to a vehicle designed to deliver exhilarating performance on both circuits and public roads.
A Low and Purposeful Stance
Achieving the lowest centre of gravity possible was a non-negotiable goal. Engineers began by determining the absolute lowest seating position and overall vehicle height that would maintain practicality while maximising performance. Once the driver placement was defined, every component – from the engine to the transaxle to the hybrid system – was positioned around this anchor point.
The result is a driving position that aligns the driver’s centre of gravity almost perfectly with that of the car, creating a sense of unity normally reserved for full racing machines.
Hybrid V8 Power with Massive Performance Targets
The GR GT debuts Toyota’s newly developed 4.0-litre V8 twin-turbo engine, paired with a single electric motor and rear transaxle in a hybrid configuration. Development targets include:
The engine features a compact “hot-V” layout, with turbos mounted between the cylinder banks, and uses dry-sump lubrication to reduce overall engine height. Power is sent through a CFRP torque tube to an all-new 8-speed automatic transmission with a wet-start clutch for sharper response.
This setup ensures outstanding acceleration and exceptional stability, with a focus on ensuring that drivers feel directly connected to the car at all times.
Aerodynamics Shaped Before Design
Most production cars undergo aerodynamics tuning after the styling is finalised. The GR GT, however, flips this process completely. Aerodynamic engineers – including specialists from Toyota’s WEC programme – built the “ideal aerodynamic form” first. Only once this model was approved did designers begin shaping panels around it.
The result is a silhouette sculpted for function first:
• a low-slung body,
• purpose-designed intakes,
• expansive cooling channels,
• and a rear section optimised for high-speed stability.
With a targeted top speed of more than 320 km/h, aerodynamic performance was treated as an engineering discipline equal in importance to powertrain or suspension.
All-Aluminium Body and Precision Chassis
The GR GT uses Toyota’s first all-aluminium body frame, combined with aluminium and CFRP panels. Large aluminium castings are positioned at major structural points to achieve maximum rigidity, while advanced joining techniques reduce weight without compromising durability.
Suspension consists of newly developed low-mounted double wishbones front and rear, fitted with forged aluminium control arms for accuracy and weight savings. The tyres – Michelin Pilot Sport Cup 2 – have been developed exclusively for this vehicle and tested extensively using both simulators and real-world track sessions.
Braking is handled by Brembo carbon discs, and the vehicle stability system includes multi-stage control levels inspired by Toyota’s Nürburgring 24-hour race programmes.
Interior Built Around the Driver
Inside, functionality takes priority over ornamentation. The cockpit is shaped around visibility, reach and the intuitive placement of controls.
Despite its motorsport DNA, the GR GT remains suitable for daily use thanks to careful attention to comfort and operability.
GR GT3: A Race Car Engineered for Victories
While the GR GT is designed as a road-legal race-inspired flagship, the GR GT3 is the full motorsport expression of that philosophy. It has been built to FIA GT3 specifications, the elite global category for customer racing.
The aim is simple: create a race car that can win – but one that drivers of varying skill levels can control and enjoy.
Born from the GR GT, Refined for FIA Competition
The GR GT3 shares the same engineering building blocks as the GR GT:
But while the GR GT balances daily usability with peak performance, the GR GT3 pushes everything toward track competitiveness. Every component is designed to handle extreme loads, temperature cycles, and prolonged race conditions.
For Professionals and Gentleman Drivers Alike
In GT3 racing, the field is a mixture of elite professionals and dedicated privateers. TGR emphasises a “driver-first” philosophy in this category as strongly as it does in its road cars. As a result, the GR GT3 aims to offer:
TGR is also preparing a customer racing support programme to complement the car’s launch, ensuring teams receive technical assistance, parts supply, and race-proven development data.
Motorsport-Proven Development, Global Testing
Both the GR GT and GR GT3 were developed using a combination of high-end simulation and real-world testing. TGR utilised racing simulators typically reserved for motorsport programmes, allowing engineers to refine fundamental characteristics before building prototype hardware.
Physical testing took place at:
This combination ensured both models would perform not only in controlled test environments but also in unpredictable real-world conditions.
One of the development philosophies was to “drive to failure, repair, refine, repeat.” This iterative process – core to all GR vehicles – ensured weaknesses were identified early and corrected through repeated cycles of testing and improvement.
Sound Engineering: Crafting the V8 Personality
Significant effort went into ensuring the GR GT’s V8 hybrid system delivers a soundtrack worthy of a flagship performance car. Toyota’s engineers focused on two sound pillars:
The exhaust system has been shaped to produce resonance that responds directly to throttle input, gear changes and load, giving the driver continuous feedback. The goal was not merely loudness but emotive communication through sound.
Charting the Future of Toyota Performance
The development of the GR GT and GR GT3 also served a deeper strategic purpose: to ensure Toyota’s next generation of engineers inherits the knowledge, intuition and craftsmanship developed through decades of motorsport and performance engineering.
Just as the Toyota 2000GT and Lexus LFA became engineering schoolhouses in their time, the new GR GT and GR GT3 are intended to pass down the “secret sauce of car-making” to future teams – Toyota’s modern version of “Shikinen Sengu,” a tradition of renewal and preservation.
Both vehicles are on track for launch around 2027, with further technical data to be revealed as development continues.
