As previously reported, the Yaris Hybrid-R develops as much as 400 horsepower from an advanced gasoline-electric hybrid drivetrain. At its heart is a turbocharged 1.6-liter four-cylinder engine. This is paired with two electric motors, which forms a through-the-road all-wheel-drive setup.
Just like in the TS030 Hybrid, the energy recovered during the braking phase is stored in a super capacitor rather than a battery. Toyota explains that this is particularly suitable for performance applications because of the high power density and quick charge and discharge speed of capacitors.
The engine, meanwhile, was developed by TMG, the German race car constructor responsible for Toyota’s former F1 cars and now the automaker’s TS030 Hybrid. The design is based on TMG’s new Global Race Engine, which has been developed for various motorsport competitions that support the same 1.6-liter format. These include WRC, WTCC and several national championships.

The Yaris Hybrid-R will make its world debut on September 10 in Frankfurt, where Toyota also plans to make a further announcement about its fuel cell plans. Toyota is committed to launching a fuel cell car by 2015 and will reveal the latest on the project at the upcoming German show.
