Chevrolet Volt chief leaves GM

A key driver of the Chevrolet Volt project is defecting to start his own consulting firm, according to published reports.

Volt chief Bob Kruse, 50, has left General Motors. He's been replaced by GM engineering veteran Micky Bly, who has also been involved with development of the Volt. The Detroit News first reported the moves on Wednesday.

The Volt is expected to debut on the market by the end of 2010 and will have a range of 40 miles on electric power. GM recently said it expects the Volt to get a 230-mpg rating from the EPA.

In his new venture, Kruse will work with companies angling for federal grant money to develop electric vehicles and battery packs.
