The second-generation Infiniti G satisfies both the left and right brain: It's fun to drive and nicely appointed, yet it's reliable and less expensive than many competitors. If I age half so well, I'll die a happy man.

An entry-level G25 sedan and high-performance G37 IPL (for Infiniti Performance Line) are both new this year. The G37 remains available in sedan, coupe and retractable-hardtop convertible form, with all-wheel drive — denoted by an "x" — optional on the sedan and coupe. Sport and Limited editions are new this year. Click here to compare the G25 and G37.
