Did a test last week
Last week I drove my car all week very conservatively. Skip shifting, easy on the go pedal, limited lane changes, etc. etc.. In Los Angeles bumper to bumper traffic on the 405 between the hours of 7am and 4:30pm. Monday - Friday. 71 miles round trip each day.
1998 Corvette Coupe ( Commute in one week )
Total Miles 355
Total MPG 24.11 ( Remember that is in bumper to bumper stop and go traffic )
My wife's car ( Wife driving. Always conservative. In same driving conditions )
2008 Honda Accord
Total Miles 190
Total MPG's 27.79
I don't care who you are. It can not be said that the Corvette can not be an economical car. When it is being driven " normally ".

I just got my Vette and I have to say I am very impressed. I just drove down to Magic Mountain area and then to Santa Barbara and back over the weekend. I was on cruise control at 85-90 most of the time and AC on full blast. In the end when I got home I averaged about 26-27mpg the whole trip, just freeway driving from home to first stop I was at 29mpg
My G35 gas mileage at best would be 22

When I went and picked up my car in Atlanta and drove it all the way back to Nebraska I drove around 70-75 the majority of the way and ended up getting right at 30mpg. Can't complain about that at all.

That's phenomenal gas mileage if it's all bumper to bumper.How much of the 71 miles are you actually seeing bumper to bumper?

My house to hwy 22. 2 miles ( usually no problem )
22 on ramp to the 405 6.8 miles ( usually at speed )
405 to the 105 ( work exit ) Awful!
So figure 53 miles and change are the stop and go traffic.

How you drive obviously can boost your mileage way beyond EPA. That is because they essentially strap on a car to a simulator and make it accelerate at a certain rate, etc. Or so I hear, don't quote me on this. It all comes down to effort. I wonder what that accord will get with such an experiment (granted you wont be moving as fast). Its also (obviously) got to do with ratios. In the vette we have quite a nice overdrive. Accords are geared more aggressively so they do not seem like pigs when you drive them. Soon maybe that will change in loo of these gas prices. But even with all this to consider, we still have a 350+ hp car that gets very very respectable gas mileage and can show off its taillights to almost anything we want it to.

People at work don't believe me when I tell them I get 30 mpg on the highway...

The C5 does get very good MPG when driven sensibly. Hard to do that at times, but it can be done.

Yeah.. the gas mileage in these is just terrible! 
Wife has a '04 325ci. she gets 25.8 MPG on her weekly commute.
My '00 Coupe is currently giving me 25.4 MPG on my weekly commute. She just shakes her head every time someone brings up the ol' "gas miles must be bad in those cars" conversation to me.

I have been testing the "hyper miling" theory myself...
Basically throwing the car in nuetral (6spd car) and crusing when coming to a stop (from a greater distance then usual), doing speed limit with conservative acceleration, etc. Basically 80% highway, but some areas of heavy traffic (stopped on the highway), but pretty minimal. (maybe 5 minutes)
I have about 100 miles on the car under this "test", and the computer is telling me that my average is 36 mpg. I have been taking it to the extreme though, coasting with the clutch in down certain inclines, bridges, off ramps, etc. (I actually saw 40.4mpg on the first trip home, and experience more traffic on the others, 33 miles each way)
I imagine real world, it may be high 20's as i have a procharger on the car and the fuel mapping is a bit different then stock.
I am happy with it either way, but it is hard to stay out of the pedal.
