2010 Lexus RX 450h

There's no denying the charms of Lexus' redesigned RX crossover. It's extremely comfortable; it packs a sophisticated, upscale interior; and, in the hybrid version, it returns the mileage of a midsize sedan — a four-cylinder one.

With all that going for it, the RX 450h hybrid has one fatal flaw: It drives like a hybrid from five years ago before most companies had worked out the odd kinks of the fuel-efficient cars, like spotty braking and herky-jerky acceleration. Aside from that, the RX is a sublime crossover.
