With 3^rd generation Prius technology under the hood (Hybrid Syndergy Drive), the Toyota Auris HSD Full Hybrid Concept Car, which will be shown off in Frankfurt at the Motor Show, is the “logical first step in deploying full hybrid technology across Toyota’s entire European model line-up.” The “full hybrid” means that there will be four driving modes; the vehicle can be operated either completely on petroleum fuel, solely on the electric motor, or on a combination of the two. The mode of preference can be selected on-demand by the driver. The fourth mode—ECO mode—will help to maximize fuel efficiency.

Here are some of the highlights:

*  Concept previews new Auris HSD Full Hybrid, Toyota’s first full hybrid mainstream model in Europe

* World debut at the Frankfurt motor show

* Hybrid Synergy Drive powertrain, shared with latest generation Prius

* Sub-100g/km CO2 emissions, class-leading combined cycle fuel consumption and 0-62mph acceleration in around 10 seconds

* Detailed exterior styling changes to improve aerodynamic performance

* Extension of on-board solar power technology

* Auris HSD Full Hybrid production model to be built at TMUK’s Burnaston factory

With this new model, Toyota hopes to “shift customer perceptions of hybrid technology” by selling them on the advantages of exceptional fuel efficiency, lower greenhouse gas emissions, and the smooth, practical stylings of this family hatchback.

The roof will be entirely covered with solar panels that will provide energy for the ventilation system. More solar panels will be installed on the dashboard of the vehicle which should provide enough energy to recharge mobile phones or portable music players in on-board charging trays. Toyota hopes to use solar to also power the battery in future models.

The Auris is scheduled to go on sale in the UK in the second half of 2010.
