Since its introduction last December, Chevrolet has sold about 3,200 Volt plug-in hybrids through the end of July. A new CNW marketing study suggests that potential Volt buyers are rapidly losing interest. CNW’s data indicates Volt’s $41,000 sticker price is the big problem although it qualifies for $7500 tax credit. The 2012 price for Volt will drop to $39,995. GM officials remain convinced Volt will meet their sales expectations which are projected to grow to 40,000 in 2012.
