The Cadillac Converj concept was shown off at the 2009 Detroit Auto Show as the first electric vehicle for the Cadillac line. It was subsequently cancelled, but as GM has experienced success with the Chevy Volt, the Converj has returned to development at the Cadillac ELR. It will have an updated version of the Voltec powertrain, so it's basically a souped-up Volt, which isn't necessarily a bad thing. The ELR is hitting production next year for a 2013 release, with specific pricing and availability details coming later.
