[cars name="Pontiac"] has shown us G6 GXP show cars before, first at SEMA in 2004 and again in New York last year. Now, in Detroit, the General is unveiling the actual production model. The most important upgrade is the 3.6-liter V-6, which produces 252 horsepower and 251 pound-feet of torque, an increase of 52 hp and 31 lb-ft over the base G6. This engine is mated to a new six-speed automatic transmission, which is one more cog than the standard G6 gets. Buyers will also get 18″ wheels to help them stand out.
For those looking for a little more flash, Pontiac will offer the Street Edition package which adds a collection of body pieces and chrome bits. Both the G6 GXP and G6 GXP Street Edition will go on sale in the fall of 2007.
