Cadillac revealed SRX crossover in 2008

GM's Cadillac division is developing a plug-in hybrid using the same range-extender technology as the Chevrolet Volt, according to media reports in Detroit.

Cadillac declined to comment on the reports on the grounds that it doesn't discuss vehicle development projects for competitive reasons.

The reports suggest that the new Cadillac would revive GM's attempts to develop a rechargeable crossover under the Buick and Saturn brands in 2008 and 2009; Cadillac previously unveiled the Converj concept, its version of the Volt, but also abandoned plans to built that.

The new project is reported to be based on the SRX which made its debut at the Detroit motor show in 2008 as a concept car that GM said could carry a fuel-cell and electric powertrain.

Launching a Cadillac range-extender would help GM to extend what its executives see as a crucial lead over Toyota for extended range electric vehicles.

GM chief executive Dan Akerson, speaking to reporters in Detroit, dismissed the market-leading Toyota Prius hybrid as a "geekmobile" that he would never want to drive adding that GM would offer versions of the Volt in different vehicle segments and under GM brands other than Chevrolet.

GM has previously said that it plans to build 10,000 Volts in 2011, but that target is being raised.
