While the world "rogue" might conjure up pirates and thieves and good guys gone bad, the Nissan Rogue crossover plays by the rules and gets great gas mileage in the process. The two-wheel-drive version of the Rogue gets a very respectable 22 miles per gallon (9.4 kilometers per liter) city, 28 miles per gallon (11.9 kilometers per liter) highway and 25 miles per gallon (10.6 kilometers per liter) combined.
One of the features helping the Rogue to achieve these mileage numbers is a continuously variable transmission (CVT). Rather than shifting through gears, the Nissan Rogue uses a belt and pulley system to transmit the power of the engine to the wheels. Nissan was the first manufacturer to use CVTs in its passenger cars, and it's worked out so well that several of its vehicles use the technology. A CVT won't crawl over boulders or pull a trailer through the mud, but it's perfect for the crossover category. Like other crossovers, the Rogue has a base price of about $21,000 [source: NissanUSA.com].
