Detroit preview - Cadillac concept

Rumors have started flying today of a Cadillac concept coupe that will see its debut this weekend at the Detroit autoshow. The car is significant in a couple of ways: 1. It is expected to preview the size and styling of the BLS replacement built on the new Alpha rear-drive chassis. 2. It is also expected to pack a version of GM's E-Flex series hybrid powertrain (like the Chevy Volt and the previous Cadillac Provoq concept). Either way you look at it - this will be a very significant concept from Cadillac if the rumors end up being true. Stand by for Cadillac's press conference likely during GM's 10am EST conference on Sunday.
