Back in July, our editors spent time with the, complimenting the vehicle on its muscle car engine, yet noting the lack of a manual gearbox option. Perhaps Pontiac reads Car Tech, because they've released the specs on the 2009 G8 GXP and they've bumped the power and included a six speed manual transmission.
Users on the GM Inside News Forum have unearthed a PDF dyno chart on GM's media site that shows the 6.2 liter LS3 V-8 engine from the Corvette transplanted into the G8 GXP generating 415 horsepower and 415 pound-feet of torque. Power will be sent through a six speed manual transmission. The six speed automatic transmission is still available.
The GXP will also feature larger 19 inch wheels and Brembo brakes, as well as slightly revised front and rear fascias.
Inside the cabin, the Pontiac will feature an updated steering wheel, but will retain the same limited audio options and lack of GPS navigation that the GT version suffers, so perhaps Pontiac's engineers haven't been listening to the Car Tech editors after all.
