Nissan has officially confirmed all the changes we've been hearing about the 09 Infiniti G lineup. On the cards is an all-new Infiniti G37 Convertible, a G37 Sedan, all-wheel-drive for the G37 Coupe (G37x) and a new 7-speed automatic transmission for all G models.

The hard-top 2009 Infiniti G37 Convertible will be hit the market mid-2009 and will make its world debut at the 2008 LA Auto Show in November. Power comes from the 330-hp 3.7-liter VQ-series V6 with VVEL technology. The 330-hp 3.7 liter V6 will also find its way under the hood of the 2009 G37 Sedan. It will be available in four models including the G37, Journey, G37 S Sport 6MT and x AWD. Sales begin in September 2008.

Nashville, Tenn. -

When you have a vehicle line - say the Infiniti G - that has chalked up award after award, topped comparison test after comparison test, and endeared itself to a growing legion of passionate owners, what do you do for an encore.

The popular Infiniti G roars into the 2009 model year with an extensive array of changes, including:

• The addition of an all-new Infiniti G37 Convertible model, slated to launch in the first quarter of 2009

"A little success makes you want to try harder. A lot of success makes you want to blow the doors off the competition again - which we're poised to do with the new, intensified Infiniti G lineup for 2009," said Ben Poore, Infiniti's vice president of marketing. "Year after year we strive to offer our customers one of the freshest product lineups in the industry - which we've done again in 2009 with the new second-generation Infiniti FX, upcoming G Convertible and the enhanced G37 Coupe and G37 Sedan."
