The extended-range electric vehicle (E-REV) was one of 60 electric or alternatively-fuelled cars travelling 60 miles from Brighton to London in the event.
Upon completing the journey, with 300 miles of range left in the family-size car, the Ampera was awarded the first ever ‘Public Choice’ award.
The Ampera completed the journey using its electric powertrain powered by a lithium-ion battery. When the charge runs low, a small petrol engine kicks in to recharge the battery and drive the motor.
This means the typical range anxiety for some electric cars is not an issue with the Ampera, as demonstrated when it drove from Germany to Switzerland for the Geneva Motor Show earlier this year.
The car, set to be released in the US as the Chevrolet Volt, will go on sale in the UK in early 2012. When it does arrive, it will be unique in the UK, as demonstrated by it being the only E-REV car in the Future Car Challenge.
"It’s been an extraordinary weekend for Vauxhall," said Denis Chick, Director of Communications for Vauxhall. "On each day we’ve showcased a car that has, or will, impact on the motor industry in a major way. We started our mission as an innovator in 1903 and 107 years later we’re still pioneers with cars like the Ampera."
The Vauxhall Ampera could be built in the Ellesmere Port plant, where the Astra is currently built, although no final decision has been announced by Vauxhall so far.
