We've heard scads of rumors over the past year that General Motors plans to bring a Volt-based Cadillac to market, and it looks like we'll be seeing a concept of the new E-Flex Caddy at the Detroit Auto Show.

According to a report by BusinessWeek, the two-door coupe concept will use the same range-extending EV drivetrain as the Chevrolet Volt, although there's no word on whether the Caddy concept will send power to the front or rear wheels. BW sources say that the vehicle is smaller than the CTS and will feature a bolder exterior design than the CTS coupe. We'll be on hand in Detroit beginning this Sunday to see the Caddivolt concept in person, if it decides to show up.
