2013 Toyota Yaris Hybrid-R

Toyota Yaris Hybrid-R 420hp hybrid powertrain details revealed

Based on the Yaris 3-door, the Yaris Hybrid R concept hybrid powertrain configuration combines the powerful 1.6l petrol Global Race Engine with two powerful electric motors to provide an 'intelligent' electric four-wheel drive capability.

Brussels, Belgium - The front wheels are driven by a 300hp 4-cylinder 1.6 turbo engine with direct injection specifically developed by Toyota Motorsport GmbH (TMG) according to the rules of the International Automobile Federation (FIA) for a Global Race Engine to be utilised in various motorsport disciplines.




Taken together, the hybrid powertrain system develops a total system output of up to 420 hp.
The two electric motors work as electric generators during the braking phase, and supplement the petrol engine during the accelerating phases.

Super-capacitor
Just like in the TS030 HYBRID, the energy recovered during the braking phase is stored in a super capacitor. Compared to the standard NiMh hybrid battery, the super capacitor has a higher power density and a fast power charge / discharge speed. It is perfectly suited to the requirements of sporty driving on track, which requires brief and immediate bursts of power.



Advanced traction control
A 3rd 60hp electric motor, located between the engine and the 6 gear sequential transmission, operates as a generator in two different cases: during deceleration to feed the super capacitor and during acceleration to directly power the rear electric motors.

The latter will only happen when the engine power and torque exceed the grip potential of the front wheels. The generator behaves like an advanced traction control system, redirecting the torque as electric energy to the rear wheels, to boost the acceleration and improve the handling rather than to simply limit the engine power.

Torque vectoring
Rear electric motors - one per wheel – can greatly influence the Yaris Hybrid-R 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.

Depending on the radius of the curve, the system can send more torque to the outside rear wheel allowing higher cornering speeds into the corner (middle-speed curves), apply more braking force to the inside wheel (fast curves), or even brake and accelerate each wheel independently (slow curves) to adjust the yaw effect for a better line, to limit steering angle, and understeer.

Exclusively Hybrid: Toyota at the Frankfurt Motor Show 2013

A presence entirely dedicated to Toyota Hybrid technology and products, featuring the World Premiere of the Yaris Hybrid-R concept and a preview of the next-step in Fuel Cell technology.

•World premiere of the new Yaris Hybrid-R concept
•Toyota Hybrid: 16 years old and already a world leader
•Fuel Cell: next-step towards the ultimate zero-emission car

Brussels, Belgium - At 2013 Frankfurt Motor Show, the Toyota stand will be devoted entirely to Hybrid.

Only 16 years young, Toyota's Hybrid portfolio counts no less than 23 models sold in 80 countries around the world. As of the end of July 2013, Toyota Motor Corporation has sold over 5.5 million Hybrid products. But this is only the beginning of the story. At the Frankfurt Motor Show, Toyota will unveil further potential technology directions in the future of low-emission and zero-emission vehicles.

Yaris Hybrid-R concept
The Yaris Hybrid-R is an exciting concept car created as a clear showcase of possible ideas for the development of hybrid technology for maximum performance and increased driving pleasure. Based on the Yaris 3-door, the Yaris Hybrid-R concept hybrid powertrain combines the powerful 1.6l Global Race Engine (GRE) developed by Toyota Motorsport GmbH (TMG) with two powerful electric motors to provide an 'intelligent' electric four-wheel drive capability. Just like in the TS030 HYBRID, the energy recovered during the braking phase is stored in a super capacitor, particularly suitable for a sports car because of its high power density and quick charge and discharge speeds. The result is a highly focused concept car dedicated to maximising driving pleasure on road and on track.

Toyota Hybrid: Only 16 years old and already a world leader


Moving forward, 16 new or updated hybrids will be introduced by the end of 2015.

Fuel Cell: Next-step towards the ultimate zero-emission car


Toyota believes that the solutions to energy and emissions issues offered by the Fuel Cell Hybrid Vehicle (FCHV) make it the closest technology yet to the ultimate zero-emission car, with hydrogen as an ideal, ultra-clean energy carrier. Before the launch of its production car by 2015, Toyota will display the latest status of its technology development.
