Based upon my experience, one should NOT have to baby your car to achieve the EPA highway estimates. Here are my last 5 cars, with results for a 375 mile highway drive between DC and Northeastern PA (i.e. includes hilly terrain along PA turnpike)
1) 1995 Nissan Maxima SE 5-speed - rated 22/27: After 11 years and 155k miles I still get 28-29 mpg on the highway at 70-75 mph with A/C on.
2) 2002 Honda S2000 - rated 20/26: Only did the trip twice, averaged 29-32 mpg on each of the 4 legs. On the last one, got 31.2 mpg for a 240 mile stretch going 75+ mph with the A/C on and top down.
3) 2004 Acura TL 6-speed - rated 20/30: Average 29-31 at 75 mph, A/C on
4) 2005 Acura MDX - rated 17/23: Average 22.5 - 24 at 70-75 mph, A/C on and fully loaded.
5) 2005 Porsche 911 S Cab - rated 19/26: I'll let you know after this weekend. Only has 1,200 miles so far, so not fully broken in.
In each of the first four cars above, I usually match or beat the EPA estimate at 70+ mph. Doesn't seem to depend on A/C use, since some of my best mpg has been in the summer. The Honda S2000 was easily capable of beating the highway EPA rating by 20% at average speeds approaching 80 mph.
If your car is not getting the highway EPA under normal highway driving, either something is wrong with the car, or the EPA estimate was an overstatement.

Sorry I forgot to mention my car is an '04 CVT based HCH.

My wife and I just traded our civic for an 06 Passat. The Civic with automatic transmission never got less than 29 in town and averaged 35-37 on the highway. We have gotten as good as 42 on a long trip. I tried higher octane gasoline a couple of times and the car did no better than with regular.
The Passat so far is getting about 23 around town and has shown as much as 33 on the highway, but we've not had it long enough to get a good idea.
We also have an 04 Mercury Mountaineer 2WD with the V6. It stinks. 14.5 around town and 19 on the highway. Best I ever got was 23 on a long trip. If you're shopping for one (or an Explorer), go ahead and get the V8, or buy an Expedition. The bigger SUV will do just as good in 2WD version around town and there is enough room for an adult in the third row.

17mpg combined driving. That's trying to get good mpg. Rated 17/24.

Back from my long weekend roundtrip of 900+/- miles. On 375 mile outbound leg, got 25.6 mpg, return leg got 25.2. Average speed was 73 mph, ranging between 65 and 82. Car is rated at 26 on highway, but not fully broken in. Not bad for a very comfortable highway ride in a car capable of 0-60 in 4.2 +/- seconds.

EPA ratings were 38 on the highway and, I believe, 32 in the city. I try to drive in such a way that I avoid much braking, rapid acceleration, etc., consistent with the traffic flow around me, coast occasionally, travel 65-70 on the highway. Highway mileage in this model seems to drop off more rapidly at high speeds than in other cars I have had. The transmission is manual 5-speed. I suspect that a sixth gear would squeeze out a few more highway mpg. I would have preferred to get an HX for the mileage, but they only come in a coupe and I preferred a 4-door. Also very few dealers carried them or showed any interest in ordering one in my area (Mass.). Thanks for your interest.

How about those EPA mileage test procedures?
This entry is directly from the 2005 EPA pamphlet:
Each vehicle in this guide has two fuel economy estimates.
City represents urban driving, in which a vehicle is started in
the morning (after being parked all night) and driven in stop and-
go rush hour traffic.
Highway represents a mixture of rural and interstate highway
driving in warmed-up vehicles, typical of longer trips in free flowing
EPA miles-per-gallon (MPG) estimates are based on lab testing
and are adjusted to reflect real-world driving conditions for an
average U.S. motorist. Vehicles are tested in the same manner
to allow fair comparisons.
According to JOSEPH B. WHITE, Staff Reporter of THE WALL STREET JOURNAL:
The EPA said methodology used to calculate city and highway gasoline mileage estimates includes a highway mileage segment, during which vehicles average 48 miles per hour. The EPA method assumes motorists spend 55% of their time in city driving.
And: The Alliance of Automobile Manufacturers, a Washington-based trade group, spokesman Eron Shosteck said "Current (EPA) test procedures provide motorists with generally reliable estimates of what their gas mileage will be... They take into account various factors that motorists may encounter in typical driving situations, in both city and highway traffic."

23.26 mpg overall for the first 4400 miles. Best highway was 27.5 but more typically around 26. 18-20 around town which I expect to drop when the cool weather moves in. I like the car a lot but I'm quite disappointed in the highway mileage. I was hoping for 28-29 which is what I got on the Olds Intrigue I was driving.
