A New Era for TOYOTA in Endurance Racing
The TS050 HYBRID features a significant change in powertrain concept. A 2.4litre, twin-turbo, direct injection V6 petrol engine is combined with an 8MJ hybrid system, both of which are developed by Motor Sport Unit Development Division at Higashi-Fuji Technical Centre.
A new generation turbo engine with direct injection is better suited to the current regulations which limit fuel flow to the engine, and provides opportunity to continue technology and knowledge transfer from the track to road cars.
Like TOYOTA road cars, the front and rear motor-generators recover energy under braking, storing it in a high-powered lithium-ion battery and releasing it as boost for maximum efficiency. The change from super capacitor to battery storage allows the TS050 HYBRID to move up to the more-powerful 8MJ hybrid class.
The TS040 HYBRID was already used as a rolling test bench and contributed to current road cars. With turbo engines increasingly in use on the road, TOYOTA expects to use the technology and know-how from WEC to make ever-better road cars.
A new powertrain concept brings different cooling and packaging demands, including an updated transmission to handle the significant increase in torque delivered by the turbo engine. Combined with a new aerodynamic concept, that means virtually every part on the TS050 HYBRID chassis has been redesigned by TOYOTA Motorsport GmbH in Cologne, Germany.
Powertrain components have played their part too in the improved aerodynamic performance of the TS050 HYBRID; by relocating the front motor-generator unit, better under-floor air flow has been achieved which will contribute to overall performance. Suspension kinematics have also been revised to optimise tyre wear.
