Borrowing technology form Toyota’s TS030 Hybrid Le Mans race car that took second place in this year’s Circuit de la Sarthe battle, the Yaris Hybrid-R is motivated by a 1.6-liter four-cylinder engine that delivers 300 BHP to the front wheels, while two 60 BHP electric motors spin the rear wheels.

According to Toyota, the vehicle’s super capacitor enables the electric motors to develop an extra 40 BHP for up to ten seconds when the road mode is selected, while the track mode will squeeze a full boost of 60 BHP out of each motor for up to five seconds.

In addition, the Yaris Hybrid-R was fitted with a third 60 BHP electric motor, located between the gasoline engine and the six-speed sequential transmission, that operates as a generator during deceleration (to charge the super capacitor) and during acceleration (to power the rear electric motors).

Also, the 60 BHP motors can greatly influence the vehicle’s handling characteristics during cornering “by altering the distribution of torque between the left and right rear wheels. Each motor can be used independently as a generator or a motor to achieve the same effect as an intelligent torque vectoring differential.”
