i have an 05 track. with very conservative city and highway driving i average 16.6 mpg, which seems low when i compare it to old threads i looked at on the forum.
so i was wondering what everyone else is getting with the new engine?

Normal driving, stop go, and highway I avg around 23-24.

If I reset the MPG gauge when on the highway doing 55mph I can touch into the 30s

Of course I don't have the new 300hp motor "just read your title lol" but I do have mods and 19" wheels.

either way you get more HP up top and shouldnt see a change in MPG over the 287HP motors. unless of course you're full throttle 100% of the time.

How many miles do you have on your car?

You will have a significant fuel economy increase after your engine is broken in, and I noticed that mine also continued to go up about another 2-3 MPG once I reached about 8k miles.

3000 miles.
i think somethings wrong with the car, it's alot slower than the 05 performance i test drove. the car feels like it's in "limp" mode, but i have no cel light.

it also allready has tranny/clutch problems.

Correct me if I'm wrong but I thought the 300hp only came in the 35th Anniv. and will be standard in the 06 models???
