Powered by the same Electric Propulsion technology seen in Chevy's Volt, the Cadillac ELR ($TBA) will use electricity as its primary source of energy with the gasoline engine generator starting only when the batteries are depleted. The ELR features a T-shaped lithium ion battery, an electric drive unit, and a four-cylinder engine-generator, motivating the car from 0-to-60 in eight seconds. Its exterior is unmistakably Cadillac, featuring an aggressive, forward-leaning profile and a design that's both sporty and sophisticated.
