The Cadillac Provoq is a concept luxury crossover SUV presented by GM at the at the 2008 Consumer Electronics Show in Las Vegas, Nevada on January 8th 2008. It is powered by the plug-in hybrid technology first shown in the Chevrolet Volt. For extended range, a hydrogen fuel cell can recharge the Lithium-ion battery and a solar panel can power onboard accessories, such as interior lighting and the audio system. As the Provoq concept uses a hybrid powertrain it is based on the same GM Voltec platform as the Chevrolet Volt. The production car shares the GM Theta platform with the Saab 9-4X. The production-spec Provoq was intended to be a replacement for the SRX, named BRX, but Cadillac retained the SRX nameplate for the new vehicle.
