For 2013, a sport-tuned IPL (Infiniti Performance Line) trim joins the Infiniti G Convertible lineup.

As highly as we rate the sedan and coupe versions of the Infiniti G line, one might assume we would be just as favorable to the convertible version. We wouldn't put money on that assumption, though, since the 2013 Infiniti G Convertible has some drawbacks that can challenge you.

Convertibles as a class are generally impractical, but in most cases, that's the price you pay for the sun on your face and wind in your hair. The Infiniti G Convertible, however, puts an even higher price on the privilege of driving al fresco. Most important, space behind the front seats is at a premium, an inevitable consequence of packaging a hardtop convertible. This is really a car just for two, as the rear seats are better used as an overflow shelf for the trunk, and maybe that's a good thing, since you'll be lucky to fit a tissue box in the trunk when the roof is lowered.

To its credit, at least the Infiniti G Convertible maintains most of the strengths that have us painting the coupe in a favorable light. The potent V6 provides plenty of power and the sport-tuned suspension makes for an exhilarating canyon carver. This year's addition of the hopped-up IPL (Infiniti Performance Line) model adds even more excitement. Then there's the classy interior that boasts easy-to-operate high-tech features and comfortable ride quality to further broaden appeal. The G Convertible also benefits from a retractable hardtop roof rather than a conventional folding fabric top, which brings added protection from the elements, security and longevity.
