88 C4 has averaged 20.1mpg since I purchased it. Car has seen 1800 miles and hopefully next year will see closer to 10k.
My old auto-x'er/current DD 02 Elantra averages about 32mpg in this winter fuel mixture crap. Summer time averages closer to 34/35.
Wife's little $2k turd Accent averages 37mpg this time of year, almost 40 in the summer. Paid $2k 40 months ago, put on over 70k miles and it just won't (sadly) die. Car is over 185k now.
The tow rig/vacation hauler averages about 19 in the winter slush. 21 in the summer pretty consistently. Summer vacations she averages 22-24 on all highway runs.
The old Swift GT(i) never got over 30mpg just driving it. Would be down to around 18-20 when it was auto-x'd and then driven afterwards. Car was a fuel hog for 1300cc's and 1800lbs
Speaking of tow rigs:
My E150 gets about 16-18 hwy if i try hypermiling, 14 or so cruzing at 70. Observed is 11 or so mixed hwy/city
This xmas break i'm at my parents house and i've spend a lot of time in their ecoboost flex which gets 22mpg hwy with cruise at 73 in the winter, the highest i've gotten was 26.9 hwy wiht attempted hypermiling last summer. And it has more power than my econoline, and a higher towing capacity. And turbos. All i have it that lousy V8! (or V7.5 sometimes) I need turbos... possibly followed by a new engine...
^ If I would actually TRY to hypermile I am certain that the tow-rig would be an easy 25mpg truck. We usually just set the cruise 70-75 (depending on the speed limit) and let it roll. Actually planning on getting it tuned this summer and see if that will get us "over the hump" into the mid-20's range. Towing 4600lbs it gets 15mpg.

Come on, guys. No more of this "If I did this, this would happen" garbage. This is like bench drag racing. Guy runs 14.60s all day, comes back to the pits, "If I could only fix this bog I'd run 12's!" No dude, you probably would run a 14.50.
Sorry, I get cranky about data, engineers are like that.
I'm assuming your tow rig is your GMC 1500? If so that's some great mileage for a sierra! My parents went through a couple of those and never got better than 14 or so, but they had a 6L engine i think, and they've never even heard the phrase 'hypermile' before. They'd probobly think it was some kind of race.
I guess since we're all chiming in here, I'll post some non "favorite" cars here:
Wife's 98 Civic DX 5 speed. 42-43 hwy and 38-40 city with her driving. I was closer to 36-37 city.
My old ZX2 5 speed. 33 mpg all of the time.
My 84 pickup, carb 350, TH350C with 3.08 gears and a topper: 19 hwy.

That's fine. Get cranky all you want. I've hypermiled my cars to some degree more. I've had other GM trucks that I was able to do "X" and get "Y". So a reasonable person would tend believe that if you had repeated said procedure and obtained said results before, it would be highly likely that you would be able to repeat it again. This truck is just so easy to drive that letting it do all the work and mindlessly put down the miles like it does I have no desire to put all my focus on mileage. getting low to mid 20's out of a 19' ling 5500lb block at 70-75mph is great. The energy required to get 1-2mpg more hypermiling it when you're going to put on 5k miles in 8 days isn't worth it to me.

That wasn't very nice. I didn't insult anyone.
83 RX-7 - 19 to 20 on the highway, 15 around town and 10 autocrossing.
The Abomination, who knows but a days autocrossing will just about empty the 3-4 gallon fuel cell.
The tow beast is a 97 E150 conversion van. It gets around 14 on the highway, I have seen as low as 10 around town. If you hook the 6000# enclosed trailer behind it and hit the interstate it drops into the single digits. Keep the speeds under 60 it gets about 11. The worst ever was 7.2 coming back from Miami towing a Wrangler on a flat trailer. Running 80 might have had something to do with it.
The Roadmaster has been getting around 17 so far. I don't think the torque converter is locking but I haven't had time to look into that yet.
The Abomination (12A with 48mm Dellorto) is a thirsty beast. The Jensenator (FI 13B) so far seems much more parsiminous. The Jensen Healey (907 Lotus with twin 45mm Dellortos) gets about 19 around town and high 20's on the road, but the highway figure was with the Getrag tranny. The Toyota box is OD in 5th so I expect to get closer to 30 on the highway. The Trooper got an all time best of ~18 at 70 MPH in light traffic. Its all time worst was 8 when towing the race car at ~80-85 MPH with the A/C on.
I got 46 in my civic a few times. I wouldn't classify it as a favorite in my book. Necessary and cheap transport is more like it.
