TOYOTA GAZOO Racing begins a new era of endurance racing with the launch of its all-new GR010 HYBRID Le Mans Hypercar, which will compete in the 2021 FIA World Endurance Championship (WEC).

The reigning World Champions and three-time Le Mans winners will defend those titles against new manufacturer competitors using a racing version of the upcoming hypercar road car, featuring powertrain technology developed in the TS050 HYBRID and highlighted via new Racing Hybrid branding.
The GR010 HYBRID is a prototype racer developed over the last 18 months in partnership by engineers at the team’s headquarters in Cologne, Germany and the electric hybrid powertrain experts at Higashi-Fuji in Japan.
The GR010 HYBRID incorporates a powerful four-wheel drive racing hybrid powertrain, with a 3.5litre V6 twin turbo engine, providing 680PS to the rear wheels and combining with a 272PS motor generator unit, developed by AISIN AW and DENSO, on the front axle. Total output is capped at 500kW (680PS), meaning the GR010 HYBRID’s sophisticated electronics reduce engine power according to the amount of hybrid boost deployed.
The striking new look of the racing prototype reflects the appearance of its inspiration, the GR Super Sport hypercar which made its public debut during a demonstration run and ceremonial trophy return at the 2020 Le Mans 24 Hours and is currently in development. To mark this new era for TOYOTA GAZOO Racing, a new livery includes the iconic GR lettering to indicate the strong link between race and road cars.
TOYOTA GAZOO Racing enters its ninth season in WEC with the same driver line-up which brought Le Mans and World Championship glory to the team in the 2019-2020 campaign. Newly-crowned World Champions Mike Conway, Kamui Kobayashi and José María López will drive the #7 GR010 HYBRID while Sébastien Buemi, Kazuki Nakajima and Brendon Hartley race with the #8 car. Nyck de Vries continues in his role as test and reserve driver.
They have already started an intense programme of developing the GR010 HYBRID, with two three-day tests already completed as the team adapts to new regulations which are a significant shift in terms of performance and philosophy.
As part of a cost-cutting initiative incorporated in the regulations, the new GR010 HYBRID is 162kg heavier and with 32% less power than its TS050 HYBRID predecessor, with Le Mans lap times expected to be around 10secs slower. It also has bigger dimensions; it is 250mm longer, 100mm wider and 100mm higher.
For the first time since the beginning of its WEC project, TOYOTA GAZOO Racing will participate without a rear motor generator unit (MGU), with the single permitted MGU located on the front axle. This means a starter motor must be fitted on the GR010 HYBRID while fully hydraulic rear brakes are also required.
The GR010 HYBRID features state-of-the-art aerodynamics, optimised for efficiency, and developed using powerful Computational Fluid Dynamics software and wind tunnel testing. The new technical regulations permit only a single homologated bodywork package, with only one adjustable aerodynamic device. The GR010 HYBRID will therefore compete in the same specification at both low and high downforce circuits, with an adjustable rear wing modifying the aerodynamic characteristics.
For the first time, the top class of WEC and Le Mans will feature a balance of performance, meaning organisers will modify the performance of each car on a race-by-race basis, regulating energy usage and weight, targeting identical performance potential from each Le Mans Hypercar. That should ensure close racing between TOYOTA GAZOO Racing and its hypercar competitors Scuderia Cameron Glickenhaus and ByKolles Racing, as well as Alpine, which will present an additional challenge with its LMP1 car.
Those battles will be fought over six races on three continents, beginning with the 1000 Miles of Sebring on 19 March prior to the 6 Hours of Spa-Francorchamps (1 May) and the season highlight, the Le Mans 24 Hours on 12-13 June. The first World Championship endurance race in Monza since 1992 takes place on 18 July before trips to Fuji Speedway (26 September) and Bahrain (20 November), all of which are six-hour contests.
Hisatake Murata: “It is a fascinating time for endurance racing”
Hisatake Murata, Team President:
“It is a fascinating time for endurance racing, with the new Le Mans Hypercar class, and also for TOYOTA GAZOO Racing, with the launch of the GR010 HYBRID. This car represents our next generation of racing hybrid. During our LMP1 era, since 2012, we worked tirelessly to improve and strengthen our hybrid technology for racing. We set new standards with the TS050 HYBRID and our first loop of racing hybrid development is complete; this technology will be available to our future customers soon. Now the second stage will begin. Through our WEC participation, we will refine our racing hybrid powertrain in the GR010 HYBRID, enhance our understanding of hypercar technology and continually develop our staff. We do this with one clear goal: to deliver more exciting sportscars to our customers in the future. The GR010 HYBRID is a preview of our road-going cars and what we learn on the WEC race tracks will directly benefit our customers. For this reason, we are delighted to welcome new competitors to the top category of WEC; a tough fight on the track will inspire us to continuously improve and push the limits for better.”
Rob Leupn: “It has been a tremendous effort from the team”
Rob Leupen, Team Director:
“It has been a tremendous effort from the team in Higashi-Fuji and Cologne, as well as our suppliers and partners, to develop and produce this new car, despite the difficult global circumstances, and we are all looking forward to show it to the world. The Le Mans Hypercar category represents a new era, with a different philosophy and new competitors; we are looking forward to this challenge. Balance of performance is something we have not experienced before in WEC but we know from our other projects that it puts the emphasis on fast drivers, perfect operations and optimal strategy. Over our nine years in WEC we have achieved a lot, but are not complacent. We always challenge ourselves to improve our technology and our processes to continuously perform better. So we have been working intensively and will continue to do so in the remaining tests before our long-awaited race debut with the GR010 HYBRID in Sebring. We look forward to finally showing our new car to the fans and being part of this new, exciting era.”
Pascal Vasselon, Technical Director: “We are all looking forward to continuing our testing programme”
Pascal Vasselon, Technical Director:
“The new regulations are designed to showcase road-relevant technology in WEC whilst also delivering a top-level, attractive spectacle. We are looking forward to welcoming new competitors and being part of an exciting future for endurance racing with our GR010 HYBRID. The new Le Mans Hypercar regulations mean the GR010 HYBRID is a completely new car, designed to a different philosophy. A major difference is the architecture of the hybrid system; we will have one kinetic energy recovery system and brake-by-wire, on the front axle. This means we had to install a starter motor and fully hydraulic rear brakes for the first time in our WEC project. Following the regulations, our car will have one bodywork specification to handle all circuits, so we needed to provide a wider working window for this car. These are just examples; there have been many such differences and challenges to address during development, so it has been an interesting engineering challenge. Now we are all looking forward to continuing our testing programme and finally seeing our new car compete; I think it will be worth the wait.”
John Litjns: “A very different car both in appearance and how it sounds”
John Litjens, Project Leader Chassis:
“The biggest difference between the GR010 HYBRID and its predecessor is in terms of the aerodynamics. In the past, the regulations limited what was allowed in many areas but under the Le Mans Hypercar rules, all cars have to be within certain performance windows in terms of downforce and drag, but there is more freedom allowed for the bodywork shapes and concepts. You can see the result of this freedom very clearly on the GR010 HYBRID. There is a similar principle on the powertrain side as well, with a given power curve but a lot of freedom in terms of configuration. The biggest change for us here was to move to only a front motor generator unit after five years with hybrid on both the front and rear axles. The packaging for the hybrid system was more challenging on this car because of updated safety standards. Additionally, the combustion engine is a more powerful on the GR010 HYBRID compared to the TS050 HYBRID. So it is a very different car both in appearance and in how it sounds.”
