The concept, which showcases possible future hybrid development ideas, is based on the three-door Yaris but features a 1.6-litre GRE (Global Race Engine) developed by Toyota Motorsport. This features two electric motors that drive the rear wheels while the engine powers the front, delivering intelligent all-wheel drive capability.

The concept also uses technology from Toyota's TS030 Hybrid race car, including a super capacitor that stores energy recovered under braking.

Fuel cell technology will also come under the spotlight, with the latest update of Toyota’s Fuel Cell Hybrid Vehicle (FCHV) technology to be shown at Frankfurt, ahead of a production car by 2015.

The carmaker said: ‘Toyota considers the energy and emissions benefits make this the best technology yet to deliver the ultimate zero-emission car, with hydrogen as an ideal, ultra-clean energy source.’

The focus on hybrid technology at Frankfurt comes as the carmaker marks 16 years since the launch of its original Prius saloon in Japan in 1997.

The Toyota press conference will take place on its stand in Hall 8 at 12.45pm on Tuesday 10th September.
