If you check out this Link you'll see Maxima owners reporting 28-30 on the Highway.
I don't think that looking at gas mileage of the different cars really reflects much about the engines. Becuase Mileage is dependant on so many other variables (Drag, Accessory load, Tire contact patch area, Tire Inflation pressure, Gearing, Quality/content of fuel,etc...).

My biggest problem with the 3.8L is that even supercharged it's a low horsepower engine for it's size. I think that since the GTP is considered a sports sedan that most potential buyers would be interested in performance. I don't think many people will mind giving up 1-2MPG to get 35-55 more HP.It was just announced that VQ 3.5L engine in the 2005 Infiniti G35 coupe will make 295HP . That's without a supercharger. GM's 3.8L is just falling farther behind, it doesn't have the technology to compete. If you look at the non supercharged version compared to the smaller nissan engine then it's a 95HP difference almost 50% more horsepower while still maintaning a nice even torque curve. Personally I'm hoping that the engine from the CTS will replace the 3.8
Also just FYI here is aLINK to Ward's 10 Best engines of 2003. They call the VQ "the best V-6 engine the auto industry's ever seen.".

Also remember that I gave a list of V-6's that are outperforming the 3.8L. I'd like to see a list of current V-6 engines (of any displacement) that the 3.8L outperforms. Anybody? I think you'll find that most of them will be from smaller automakers like Hyundai, Daewoo, Kia, etc. I think that it will be hard to find many <200HP V-6's being built by any of the big American, Japenese, or German Automakers. After all there are a numberof 190-200Hp 4 cylinder engines now.
