Pontiac unveiled at the New York Auto Show the G8 sport truck . Back then the company announced that the production version will be powered by the same 361-hp 6.0L V8 power plant that is found in the Pontiac G8 GT.
But since then gas price went crazy! And a V8 engine might not be the best choice. So, Pontiac decided to put a V6 engine under the hood of the future G8 ST (or El Camino, or what ever the name will be!).
This would be the same 3.6L 256-hp V6 found in the G8 V6 sedan, and would have the same 17/25 mpg fuel economy as the V6 sedan.
