With political uncertainty in oil-producing states, and the rising gas prices that brings, you can expect to see a lot more headlines saying "40 MPG!"
We just did a quick overnight road test of a 2011 Chevrolet Cruze Eco with the six-speed manual transmission, which the EPA rates at 28 mpg city and a stunning 42 mpg on the highway cycle.
Did it get us 42 mpg? No, of course it didn't.
Highway rating vs. real world
You're most likely to approximate the EPA's highway mileage rating if you are driving at the speed limit (or lower) on a nice, flat piece of well-paved highway with no head winds, the windows fully raised, and none of the car's accessories running.
That, unfortunately, is rarely a realistic situation for how we all drive these days.
Chevy cheats a little, providing an "instantaneous mileage" display in the cluster. It flickers from 14 mpg (acceleration up a hill at speed) to 99 mpg, the most it will register, when the engine is doing essentially no work. The figure is diverting, but also distracting.
Cumulative mileage: 34.4 mpg
The more important number is the cumulative gas mileage. Our results: On a 275-mile overnight journey, in temperatures from 20 to 50 degrees F, we averaged 34.4 miles per gallon.
That's actually slightly better than the EPA's combined 33-mpg figure for the six-speed Cruze Eco. The highway-heavy mix of travel (we only spent perhaps one-fifth of our miles on around-town and low-speed stop-and-go driving) probably accounted for that.
Looking only at highway mileage, it's possible to average as much as 44 mpg for long trips with no stopping and starting. Again, though, very few people spend all their miles on Interstates, much less uncrowded Interstates where traffic flows freely and no one ever has to jam on the brakes.
33 vs 40 mpg? Don't obsess
Just for perspective, the difference in gasoline consumption between 33 mpg and 40 mpg is half a gallon every 100 miles--or less than $2 at current gasoline prices. If you drive 10,000 miles a year, that's less than $200, or about $4 a week.
While we wouldn't advise you how to manage your money, we think that for all practical purposes, 33 miles per gallon is a perfectly respectable fuel efficiency rating.
$19,745 out the door
The 2011 Cruze Eco we tested had a sticker price of $19,745. That's a base price of $18,175, plus a $525 connectivity and cruise-control package, $325 for the very dashing Crystal Red Metallic Tintcoat paint, and a mandatory $720 delivery charge.
By comparison, the 2011 Toyota Prius--a midsize hatchback, not a compact sedan, with a combined 50-mpg rating--has a base price of $23,810 including shipping.
40 is the new 30
The 2011 Hyundai Elantra, which the EPA rates at 40 miles per gallon on its highway cycle, is leading Hyundai to challenge other carmakers to report how many vehicles they sell rated at 40 mpg or better.
Ford has two separate non-hybrid models that get 40 mpg or better on the EPA highway cycle. To be fair, like the Cruze Eco, they're special option packages--the base versions don't quite hit that magic number.
And indeed, 40 seems to be the new 30 (mpg), or the magic number carmakers want to tout in their ads.

Reminds me of all the silly Prius drivers reporting 60 mpg or something. Well, great if it is an average over many trips, but often times it is not. Also, it probably doesn't represent what most people will experience. Stick to the EPA numbers.
But think about it for a minute. 40 MPG is 21% more efficient than 33 MPG. The USA uses 136,000,000,000 gallons of gasoline per year. 21% of that is 28,000,000,000 gallons per year. At $3.50/ gallon that is US$100 billion/year. Add to that a 21% reduction in auto based CO2 and 21% reduction in pollution, and you get the idea.
Achieving 21% reduction is a $100 billion/year reduction in expense, now THAT is respectable.

The most efficient model listed shows.
"Fuel consumption: official: , a-c pred. average combined: 11.7 l/100km / 28.1 mpg (imp.) / 23.4 mpg (U.S.) / 10 km/l"
So 23.4 MPG combined, so I suppose 34 mpg highway is possible if a bit of a stretch.
But also shows 0-60 of 17 seconds. Remember that next time you say a modern car accelerate slowly.
Says 32 MPG with the 144 cu.in. engine.

My 2009 VW Jetta Sportwagen TDI M6 has averaged 41.5 mpg over the last several thousand miles, in mixed driving on highways & the suburbs. It is EPA rated 30/41 mpg. On the highway I drive a bit above the 65 mph speed limit, and there it gets about 45 mpg. The owner reported average on fueleconomy.gov is 39.6 mpg.
My 2006 Toyota Tacoma 4WD TRD Offroad V6 A5 pickup, which always carries several hundred pounds of gear, has averaged 19.5 mpg over the past few thousand miles. Under the 2008 EPA mpg method, it is rated 16/20 mpg. On the highway, driving slightly above the speed limit, it averages 21-22 mpg.
If the ECO Cruze cannot get at least 42 mpg driving 65 mph on the highway, then perhaps GM built it to excel in the EPA test cycle and not the real world.
