Using a new power unit gave the engineers at TMG the opportunity to re-evaulate all areas of the car. The new powertrain presents some challenges, particularly in terms of weight and cooling” explains Hisatake Murata, General Manager Motor Sport Unit Development Division. Combined with our move into the 8MJ class, this will give us significantly improved torque compared to the previous powertrain this was a key target for the new car. We believe a V6, direct injection, twin turbo engine achieves the best balance of power and efficiency considering the current regulations. As motorsport engineers, we want to always increase the performance of the powertrain so it was important to compensate for this reduction with a more efficient, powerful powertrain. “The regulations for this season include a reduction in fuel flow and total fuel energy of approximately 7.5%. In terms of the engine it was an all new purpose built design which is extremely compact. These are linked to the cockpit mounted energy store which this year for the first time uses a lithium-ion battery pack in place of the capacitors found in the TS030 and TS040. The hybrid system featured two MGU-Ks (Motor-generator-unit-kinetic) one at each axle. The whole power unit was developed by by Toyota’s Motor Sport Unit Development Division at Higashi-Fuji Technical Centre in Japan while the rest of the car was designed and built by TMG in Cologne, Germany While visually it had a clear resemblance to the previous car, the TS040, it was at the same time very clearly a different car.Īt the heart of the new machine was an all new power unit consisting of a 2.4 litre twin-turbo direct injection V6 engine mated to an 8MJ hybrid system. Toyota’s 2017 LMP1 was an evolution of its 2016 contender.
