New GR010 Hybrid, the successor to the triple Le Mans-winning TS050 Hybrid, will influence forthcoming GR range-topper
Toyota has revealed the new GR010 Hybrid Le Mans Hypercar that it will field in this year’s FIA World Endurance Championship, and which previews the firm’s forthcoming GR Super Sports road-going hypercar.
The new GR010 is built for the new Hypercar prototype class being introduced into the top level of endurance racing including the Le Mans 24 Hours this year, and is the successor to the TS050 Hybrid that has won the last three editions of the French event.
Developed at Toyota’s European motorsport made in Cologne, Germany, the GR010 Hybrid features a new four-whee-drive hybrid powertrain developed by Toyota engineers in Higashi-Fuji, Japan based around a 500kW 3.6-litre V6 twin turbo engine mated to a 214kW electric motor mounted on the front axle. The powertrain uses a seven-speed gearbox.
Under the Hypercar regulations, the total output of the system is capped at 500kW, so the car will split the output between the engine that drives the rear wheels and the electric motor, which powers the front, as needed.
The power output is 32% down on the TS050 Hybrid, which was produced under the previous LMP1 regulations and used a 2.4-litre twin-turbocharged V6 with a hybrid system powering the rear wheels.
As required by the new regulations, the GR010 is 162kg heavier than its predecessor, weighing 1060kg. It is 4900mm long, 2000mm wide and 1150mm high, making it 250mm longer, 100mm wider and 100mm higher than the old car. Toyota expects lap times at Le Mans to be around 10 seconds slower.
Toyota used CFD software and extensive wind tunnel testing to hone the shape of the GR010 Hybrid. The new rules require a single homologated bodywork package, and allow for only one adjustable aerodynamic device which, for the GR010 Hybrid, is the rear wing.
The top class of the WEC and Le Mans is now open to cars built to the new Hypercar rules, such as the GR010 Hybrid and the forthcoming machine from Peugeot, the LMDh rules that Porsche’s forthcoming contender will run to, and adapted LMP1 cars, such as the machine Alpine will back this year.
A Balance of Performance (BoP) system based around energy usage and weight, will be used to adjust the performance of each car on a race-by-race basis.
The WEC season is due to start in Sebring, Florida on 19 March, with Le Mans running on 13/13 June. Toyota Gazoo Racing will retain an unchanged line-up for the two cars it will run in this year’s WEC. Reigning world champions Mike Conway, Kamui Kobayashi and Jose-Maria Lopez will drive the #7 car, with Sebastien Buemi, Kazuki Nakajima and Brendon Hartley in the #8.
The road-going Super Sports Hypercar
Gazoo Racing technical director Pascal Vasselon said that the styling of the GR010 Hybrid was set after discussions with Toyota’s GR road car division to ensure certain styling points – particularly around the front and rear – matched the forthcoming production version of the GR Super Sports Concept.
While the road-going hypercar’s design will take styling cues from the GR010 Hybrid, it is set to use a reworked version of the old TS050 Hybrid’s 2.4-litre V6 twin turbo hybrid powertrain. In competition form that unit produced 735kW, although that will likely be detuned for the production version.
The GR Super Sports Concept made its public debut with a demonstration lap at last year’s Le Mans 24 Hours. The firm has yet to confirm when the machine, which will serve as the aspirational range-topper of Toyota’s GR performance models, is due to go on sale.
