The Lexus IS-F is one smokin’ ride, no question about it. But that big V-8 engine is thirsty enough to suck the oil right out of the ground if it could. So go to the other end of the scale: The $32,490 IS 250. Sure, it doesn’t have the power of its big brother, but it looks great and gets exceptional mileage from its 2.5-liter V-6 engine: 21 city, 29 highway, and 24 combined. Plus, it has a luxurious interior, is no slouch thanks to 204 horsepower. You have to skip the manual and the all-wheel drive versions, since mileage for both slip below our criteria.
