Toyota Gazoo Racing Unveils GR GT3 Concept and GRMN Yaris as Embodiments of Making Ever-better Motorsports-bred Cars

TGR is committed to further accelerating customer motorsports activities to make the world of motorsports sustainable. Promoting "driver first" car development and with a desire to provide attractive cars for customers participating in GT3 (which is the pinnacle of customer motorsports), TGR has unveiled the GR GT3 Concept.

As was the case with the GR Yaris, by commercialising motorsports cars rather than simply adapting production vehicles for use in motorsports, TGR intends to use feedback and technologies refined through participation in various motorsports activities to develop both GT3 and mass-production cars and further promote making ever-better motorsports-bred cars.

GRMN Yaris

Concept

Following on the resounding global success of the GR Yaris, Toyota has pulled the covers off an even 'hotter' version; the GRMN. GRMN models represent the top tier in the Gazoo Racing pyramid and embodies the 'total tuning concept'.

Since its launch, the GR Yaris has been involved in various motorsports, such as the Super Taikyu Series where President Toyoda got behind the wheel as Morizo and participated with ROOKIE Racing, and the Japanese Rally Championship*5, where it won the season championship.

The development of the GRMN Yaris began from Morizo's desire to "deliver cars to customers that evolve quickly and can be tailored to individuals like in the field of motorsports." Using lessons learned from motorsports competition, body rigidity has been enhanced, weight has been reduced, overall width has been increased for aerodynamic improvement, while vehicle height has been reduced by 10 mm for a lower centre of gravity.

The GR Yaris has evolved into a car that can be driven faster and with more peace of mind, with improved braking force, grip, cornering and acceleration, based on feedback from professional drivers.

GRMN Vehicle Outline

Based on the GR Yaris, the GRMN Yaris has achieved the ultimate in lightweight sports 4WD by applying a wide range of technologies and parts developed through motorsports, to focus on weight reduction and enhanced body rigidity.

It features a close-ratio gear transmission and a low final gear set that has been refined in the field of motorsports. For gear ratios, close-ratio 1st to 4th gears make efficient use of the engine power band, and low final gears for optimized driving force have been combined. To improve reliability during endurance races and other situations, SNCM material was used and shot processing was added to 1st, 3rd, 4th, 5th, and final gears, significantly improving shock torque and fatigue strength.

Mechanical LSD's (front and rear), replace the Torsen versions in the GR Yaris while a reinforced metal- matrix clutch has also been incorporated.

In addition to the lightweight high-rigidity carbon (twill weave CFRP) used for the hood, roof, and rear spoiler, removing the rear seats to make it a two-person car, has achieved weight reduction of approximately 20 kg compared to the GR Yaris.

Increased rear track width (+5mm) improves grip, while a 10mm width increase boosts aerodynamic performance.

Engine power remains at 200kw (Japanese specification), with Torque boosted by 20Nm to 390.

Furthermore, through the two 'Update Program' and 'Personalization Program' services, Toyota will provide customers with "cars that evolve quickly and can be tailored to individuals" just like they are in motorsports.

The GRMN Yaris offers race-car like enjoyment while being able to tailor the vehicle to suit the owners’ preference and vehicle usage. To this note, two bespoke packages are offered, a Circuit Pack and Rally Pack, each customised to extract maximum performance from the GRMN Yaris in the discipline chosen.
