GM transplants Chevrolet Volt technology into the Cadillac ELR hybrid

One of the headliners of the 2009 Detroit auto show, the Cadillac Converj concept, will become production reality. Cadillac confirmed some details on Wednesday afternoon and said that the coupe will be called the ELR. It will use a T-shaped lithium-ion battery pack, and a generator kicks on to extend range, similar to the Chevrolet Volt.

There's a 2015 Ford Mustang convertible on the way, too

Almost immediately after the Ford Mustang debuted, buyers could choose from three body styles -- a hardtop, a rag-top convertible and a fastback (which actually came out a few months later than the hardtop and convertible). We already knew that the 2015 Mustang will arrive as a fastback (sorry, notchback partisans), but Ford has just announced that a drop-top version is also in the works. Pictures of the convertible sport a shiny "5.0" badge on the side and and chrome "GT" badge on the back, but we assume all the standard engines -- the 5.0-liter V8, 3.7-liter V6 and that new 2.3-liter EcoBoost turbo-four -- will be offered.
