Nissan has come a long way since the days when it was called Datsun. Now it's home to the Altima mid-size sedan. The Rogue SUV is quiet and comfortable and offers plenty of cargo room, too. At the top of the lineup sits the venerable GT-R, which earns its reputation as a slayer of supercars as well as its nickname—Godzilla—with a burly 565-hp twin-turbocharged V-6. The cheap and cheerful Versa is at the other end of the spectrum, which is one of the most affordable new cars sold in the United States.
