GM has tested the first pre-production Chevrolet Volt for the first time on US roads, almost two weeks ahead of schedule.
The firm had aimed to test the Volt on 4 July, but Tuesday’s test has moved the project ahead of schedule and more test drives are now taking place.
GM currently aims to have the Volt in showrooms by November 2010. Its complex powertrain is set to undergo extensive pre-production tests to ensure all problems are ironed out before it goes on sale.
Andrew Farah, the Volt’s chief engineer, said: “By exceeding our own pre-production deadlines, it allows us additional time to refine the vehicle.”
The Volt can reportedly has a 40 mile range on battery power alone. When this charge runs out, a petrol range-extender engine keeps the car moving.
In the UK it will be badged as a Vauxhall Ampera, and should go on sale here in 2011.
