Close, Richard. It is a 2005 Infiniti G35 Coupe 5AT, not 6MT. I opted for the 5-speed auto.
In the auto, it only generates 280 hp.
However, a slight flick of the wrist and the addition of a "Z-Tube", the air intake box from the Nissan 350Z (same motor), will restore the shackled beast to its full, unadulterated 298 horse glory.
Frankly, I have to keep opening the hood and counting the cylinders. It sounds and feels like a 5 liter V-8 to me.
