Photos of Prius leaked on internet

Images of the new Toyota Prius have been leaked on the internet, ahead of the petrol-electric hybrids cars launch in 2009.

The pictures show that Toyota has retained the current versions proportions, but that the new car has been given a smoother, yet more aggressive look.

It is expected that a larger capacity 1.8-litre petrol engine combined with an electric motor, will provide the power. The new car will be capable of more than 70mpg on average, while emissions should be less than 90g/km.

The new Prius will use the current cars nickel hydride battery pack, but could switch to lithium-ion batteries in 2010 if they prove more reliable.
