Toyota Yaris Hybrid-R concept (2013) at Frankfurt motor show

Toyota has released fresh information regarding its 414bhp supermini concept ahead of its debut at next month’s Frankfurt motor show. The Yaris Hybrid R drivetrain features Toyota Motorsport’s 1.6-litre racing petrol engine to power the front wheels and twin electric motors generating 60bhp apiece to run those at the back, giving the car all-wheel drive and a combined output of up to 414bhp. The car also makes use of a supercapacitor inspired by Toyota’s TS030 Hybrid Le Mans racer – energy generated under heavy braking is stored and can be quickly deployed to the rear wheels for an extra burst of power.
