Chevrolet Volt can achieve 230 mpgAugust 20, 2009
Preliminary data suggests that the Chevrolet Volt will achieve city fuel economy of at least 230 mpg (US), given a single charge per day.
Although the data has been analysed in America, remember that the Chevrolet Volt will also be available in the UK in 2012 as the Vauxhall Ampera – which is an electric car, but with a 1.4 litre 4-cylinder petrol engine to power the electric motor when the battery runs low.
Based on draft Environmental Protection Agency (EPA) for extended-range electric vehicles (EREV) methodology, the Volt would also deliver “triple-digit” combined cycle fuel economy.
In the US, GM calculates that a typical Volt driver would pay about $2.75 for electricity to travel 100 miles, or less than three cents per mile.
Many Chevy Volt drivers might be able to be in pure electric mode on a daily basis without having to use virtually any petrol, as according to US Department of Transportation data, nearly eight of 10 Americans commute fewer than 40 miles a day.
Actual testing with production vehicles will occur next year closer to vehicle launch in the US. The problem is that it’s difficult to express fuel economy in a way comparative to petrol or diesel for new technologies such as the Volt, so the EPA is trying to address the issue, and may come up with one calculation for extended range electric vehicles, and one for plug-in hybrid electric vehicles.
The Volt is expected to travel up to 40 miles on electricity from a single charge of its 16 kWh Li-ion battery pack and be able to extend its overall range to more than 300 miles with its flex-fuel-capable engine-generator. The Volt is currently delivering 40 miles just in electric mode in both city and highway cycles.
