Infiniti G Convertible

The second-generation Infiniti G37 coupe - badged Nissan Skyline in Japan - was previewed by the Coupe Concept at the 2006 NAIAS show and debuted in production form at the 2007 New York Auto Show. Now, at the 2008 LA Auto Show, the convertible version has appeared with a three-part folding hardtop, following BMW's lead with the conceptually similar 3-Series cabriolet. Powered exclusively by a 3.7-liter V6, the G37 convertible comes with a specification that includes leather seats, a 'power walk-in' device that electrically moves the front seats out of the way to help ingress and egress to the rear, and air-conditioning that automatically detects whether the roof is up or down.
