I think the Ford Escape Hybrid has a V6 gas engine along with the electric. It can be had in 2WD and 4WD versions. Ford licenced the hybrid electronics from Toyota but uses Ford-built engines. Another good option would be the Volkswagen Jetta TDI. It has a direct-injection Diesel engine that, using new technology, doesn't have the "clatter" you normally associate with Diesels, has good low-end torque for off-the-line acceleration, and gets 38 city/46 highway mileage.
