2013 Infiniti IPL G convertible officially announced at Pebble Beach

In an expected move, Infiniti has announced it will build a production version of the IPL G convertible concept seen at this year's New York Auto Show. The 2013 Infiniti IPL G convertible will likely share hardware with the IPL G coupe on sale now, and the power retractable hardtop used by the G37 convertible.

IPL, which stands for Infiniti Performance Line, is the manufacturer's in-house performance department, serving as an extension of the Nissan NISMO works into the company's luxury division. The IPL G convertible will be the second IPL car to go on sale.

The Infiniti IPL G coupe was introduced at last year's Pebble Beach Concours d'Elegance. That car uses a 3.7-liter V6 engine boosted to 348 hp, up from 330 hp in the conventional G coupe, thanks to exhaust and engine-management upgrades. Torque is up 6 lb-ft to 276 lb-ft. Engine redline is increased from 7,000 rpm to 7,400 rpm, and the torque curve is modified for more linear acceleration. The engine is paired with a seven-speed automatic or short-throw six-speed manual.

Expect full details on the 2013 IPL G convertible to arrive closer to the car's official coming out party at the 2011 Los Angeles Auto Show in November.
