Toyota has released further details of its Yaris Hybrid-R concept, due to be unveiled at the Frankfurt Motor Show next month.

The Yaris Hybrid-R concept features a 1.6-litre petrol engine combined with two electric motors to provide all wheel drive.

The system, which uses technology borrowed from Toyota’s TS030 Hybrid race car, can store energy recovered under braking in a large capacitor which features a high power density and quick charge/discharge speeds.

This power can then be fed back in to the system to provide improved fuel efficiency and rapid acceleration.

Combined, the petrol engine and electric motors are reputed to be able to deliver 400bhp.

Toyota will also use the show to celebrate 16 years of hybrid technology, with its stand dominated by its various hybrid vehicles.

The company revealed that it expects to introduce 16 new or revised hybrid models before the end of 2015.

The company will also share details of its Fuel Cell Hybrid Vehicle which is set to go into production by 2015.
