Toyota's hybrid Auris will be the most expensive in the range, and could cost over £20,000 when it goes on sale in the middle of next year.
The production version of the Toyota HSD Auris Full Hybrid concept will be the first hybrid model to be built in Europe at the firm’s Burnaston plant in Derbyshire. The top Auris currently costs £19,000 and the hybrid will demand a premium on that.
It shares its hybrid powertrain with the third-generation Prius, which was launched in the summer. It has a 97bhp 1.8-litre petrol engine as well as nickel-metal hydride batteries and an electric motor. It has the ability to run on electric power alone for up to 1.25 miles at speeds of up to 31mph.
Acceleration from 0-60mph should take around 10 seconds, while its CO2 emissions are expected to be around 90 g/km.
The Auris has had a range of aerodynamic tweaks to keep its drag coefficient down to 0.28. These include a front end designed to optimise airflow and maximise fuel efficiency, flat corners on the front and rear bumpers and0mm lower ride height than a standard Auris.
Other changes include underbody panels and a rear diffuser to help channel airflow under the body, turbulence-reducing 18-inch alloy wheels and low rolling resistance tyres, as well as a larger rear spoiler.
Solar power technology also features, with panels on the roof helping to charge the batteries. Solar panels also appear on the dashboard to help charge mobile phones or after market sat-nav systems. LED lights feature at the front and the rear.
