Toyota has the Yaris Hibrid-R ready to rock&roll for Frankfurt Motor Show

Toyota has released new details about the powertrain of Yaris Hybrid-R concept, before its debut at the Frankfurt Motor Show.

This intriguing new concept relies on a 4WD driveline derived from racing. In an unusual twist, Toyota used a combination of a capacitor and motor-generator, instead of the battery pack that typically powers the motors in contemporary hybrids. The 1.6-liter four-pot is responsible for driving the front wheels, whilst the two 60-horsepower electric motors each drive one rear wheel. This all-wheel-drive setup will produce a maximum of 414 horsepower. By having electric motors at each rear wheel, Toyota hopes to have achieved a system that can split the torque, thus increasing the car's cornering and handling capacity.

The car's supercapacitor was inspired from Toyota’s TS030 Hybrid Le Mans racer. The basis of it is that energy generated under heavy braking is 'temporarily stored' and is fastly deployed to the rear wheels to provide an extra burst of power.

More so, under heavy acceleration, if the front wheels can’t cope with the power and torque coming from the turbocharged four-cylinder engine – it again works as a 'generator', sending excess torque to the rear motors as electrical energy, a form of traction control designed to boost acceleration and control.

The exterior of the Yaris Hybrid-R Concept is still in a rendering stage, but the design looks ready for the Frankfurt Motor Show. Featuring blue highlights on the side skirts, the base coating appears to be either white or silver. The car also boasts a huge air intake to keep things cool under the hood and in the braking system. As for the interior, there are currently little details available.

The Hybrid-R concept will be fully unveiled on September 10th, in Frankfurt.

Ever since the first Prius in 1997, Toyota calculates that its global hybrid fleet has saved roughly 12 billion litres of fuel and 34 million tonnes of CO2 emissions, compared to the same number of equivalent, conventionally powered vehicles.In the next 2 years Toyota plans on introducing another 16 new or revised hybrid models.
