Chevrolet’s upcoming Volt plug-in hybrid will get 230 miles per gallon according to General Motors. The astonishingly high number comes as the result of new EPA methods for testing fuel mileage for PHEVs.
GM made the announcement today as a part of a product and technology event held at the company’s Design Center and Milford Proving Grounds.
How exactly GM came by that number we can’t say for sure, but we can say that it is for city driving only. Highway driving won’t be as high, but GM says that number will still be in the triple digits. What we do know is that the number is somewhat of an average between those who don’t ever need to gas up and those who do.
GM also had this to say on the matter:
The EPA methodology uses kilowatt hours per 100 miles traveled to define the electrical efficiency of plug-ins. Applying EPA’s methodology, GM expects the Volt to consume as little as 25 kilowatt hours per 100 miles in city driving. At the U.S. average cost of electricity (approximately 11 cents per kWh), a typical Volt driver would pay about $2.75 for electricity to travel 100 miles, or less than 3 cents per mile.
The Volt will officially go on sale next year as a 2011 model and will be able to travel up to 40 miles on pure electric energy before the gasoline engine kicks in, extending the vehicle’s range to 300 miles.
