Fuel cell Caddy concept is identical to road-going small 4x4 model
14 January 2008

This car was actually unveiled last week at the Consumer Electronics Show in Las Vegas, but GM unveiled it again this morning for the Detroit show. Ostensibly a concept showcasing the first use of GM’s E-Flex system in a Cadillac, it is also Cadillac’s new small SUV that will take on the likes of the Land Rover Freelander and BMW X3.Underneath sits a chassis shared with the Saab 9-4X concept, a mix of GM’s Theta (used in the Vauxhall Antara) and Epsilon platforms (which underpins the Vectra). The production vehicle will be indistinguishable from the concept – a close look at the car shows a production ready interior similar to the CTS saloons and built to a very high standard.But it’s what powers the Provoq that’s really significant. It uses another variant of GM’s E-Flex alternative fuel system, with a fuel cell providing most of the propulsion with battery back-up. It has a range of 280 miles on a tank of hydrogen, and the batteries add another 20 miles to that. At the unveiling, Cadillac boss Jim Taylor hinted that his brand would use E-Flex, saying that it fitted with the marque’s history of innovation and use of new technology. So it’s likely the production Provoq will eventually be available with an E-flex option, although it’s unlikely to before 2010, when the Chevrolet Volt is launched.
