Look everyone, it’s a Chevy Volt that can seat more than four people! Official images of the Volt MPV5 concept have leaked today [via AutoblogGreen], confirming what recently-discovered line drawings hinted at: a people-carrying version of Chevy’s Volt is under development. The extra rear seat and the 30.5 cubic feet of storage space (62.3 cubic feet with rear seats folded) does come at a price though, as GM says the MPV5 comes up 8 miles short of the Volt’s marketing-mission-critical 40 miles of electric range using the same drivetrain. On the upside, it will almost certainly be classified as a light truck (despite its compact, FWD underpinnings), making it the perfect vehicle to goose increasing CAFE standards.
