We were totally digging Volvo's ReCharge plug-in hybrid
concept when they were showing it off last year at the Frankfurt Motor Show, but unfortunately it wasn't much more than a cutaway demonstration model at that point. Lucky for us, Volvo decided to take it legit, and built a full-on working concept model of the Volvo C30-based car. The company is teamed up with Saab in a five-year plan to develop plug-in hybrids, and they're currently planning a fleet of 10 cars to be tested in Sweden. Volvo plans to announce a hybrid version of one or more existing models within the next five years, but they're certainly playing it safe -- though the lithium-polymer batteries and in-wheel electric motors might prove them otherwise.
