Bob Lutz has apparently gone on record saying that it's high time Cadillac makes a significant environmental statement (you know, something north of 21 mpg). They also figure that Cadillac is a prime suspect because so many other GM divisions have tenuous futures with the exception of Chevrolet, which already has the 2011 Volt. Finally, the higher purchase price of a Cadillac could better absorb the costly development and powertrain technology needed for an E-REV vehicle without turning to Uncle Sam for massive assistance as in the case of the 2011 Chevrolet Volt.
Cadillac did unveil a Provoq concept last year with an E-Flex drivetrain and fuel cell technology. GM-Volt.com say that the Provoq will materialize as the next SRX crossover, furthering speculation that this new secret E-REV will indeed be clothed in SRX guise.--Colin Mathews
