Chevrolet is already working on reducing the productions costs of its second-generation Volt to bring its list price in line with more mainstream rivals.
The company will place particular focus on the Austrian-built 1.4-litre petrol engine to keep costs down.
Chevrolet's work could in fact see the current engine be axed from the line-up altogether, in favour of a more sophisticated and frugal version.
The current Volt will cost $41,000 (£26,000) in the US, although final UK pricing has yet to be revealed. Previous estimates have suggested the car will come in at just under £30,000 - but not by much.
The first production versions of the first-generation Volt are currently being built in Detroit.
