Car Manufacturer's MPG busted by Consumer Reports.

TweetNot that any of this surprises me because companies will always lie if it means more money in their pocket.

Consumer Reports offers in-depth vehicle reports for every model tested - to help you make the right purchasing decision on your next car or truck.




Why you're not getting the miles per gallon you expect.


Shortfalls in mpg occurred in 90 percent of vehicles Consumer Reports tested and included most makes and models.



For years, automakers have been criticized for producing vehicles that get so-so gas mileage. But as gas prices climb and consumers seek more miles per gallon, it turns out that fuel economy is much worse than it appears—50 percent less on some models, a new Consumer Reports analysis reveals.
Drivers who track their own fuel economy have long known that their results seldom match the gas mileage claimed by the Environmental Protection Agency on new-car stickers. Our study, based on years of real-world road tests over thousands of miles, quantifies the problem across a wide swath of makes and models.

We compared the claimed EPA fuel economy with the mileage per gallon we measured for 303 cars and trucks for model-years 2000 to 2006. Our selection represents a good cross-section of mainstream, high-volume vehicles. We looked at city, highway, and overall mpg.

Highlights of our study:


Shortfalls in mpg occurred in 90 percent of vehicles we tested and included most makes and models.

The largest discrepancy between claimed and actual mpg involved city driving. Some models we tested fell short of claimed city mpg by 35 to 50 percent.

Hybrids, whose selling point is fuel thriftiness, had some of the biggest disparities, with fuel economy averaging 19 mpg below the EPA city rating.

The EPA ratings are the result of 1970s-era test assumptions that don't account for how people drive today. Automakers also test prototype vehicles that can yield better mileage than a consumer could get.

Despite federal certification, it appears that U.S. vehicle fleets, all cars and light trucks produced in one model year, don't meet government fuel-economy standards. For example, fleet mpg for 2003-model-year vehicles we studied was overstated by 30 percent.

For consumers, the news means that their vehicles typically cost hundreds more per year to operate than they were led to believe. Put another way, when gas in August 2005 hit $2.37 per gallon, the mpg shortchange effectively boosted the price for some motorists to $3.13 per gallon.
For the nation, where the fleet average fuel economy is near its lowest point in 17 years, the findings suggest that the country is far short of its energy goals.

"We are concerned about the differences," Margo Oge, director of the EPA's Office of Transportation and Air Quality, said of our study. "I think we can do a better job to help consumers assess actual fuel economy."

Other ways to save money on auto travel


Be skeptical of EPA ratings. The EPA sticker can help you evaluate relative gas mileage among vehicles, but not absolute mpg. Until the EPA ratings are made more realistic, discount the EPA sticker numbers for city travel as follows: conventional cars and trucks, 30 percent; larger hybrids, 35 percent; diesels, 36 percent; smaller hybrids, 42 percent.

Buy regular. If your car owner's manual doesn't recommend a particular grade of gasoline, fill 'er up with regular. And don't waste money on so-called gas-saving devices; our tests have shown that they don't work.

Walk, bike, or "chain." Fuel economy is worst on short trips. These trips also create the most exhaust emissions and cause the most engine wear. Half of all car trips are under six miles, within walking or biking distance. If you must drive, "chain" several errands into a single trip on a warm engine instead of making separate short trips throughout the day.

Avoid highway drag. At highway speeds, where fuel economy is best, more than 50 percent of engine power goes to overcoming aerodynamic drag. Try not to add to that drag by carrying things on top of your vehicle. A loaded roof rack can decrease a car's fuel economy by 5 percent. Even empty ski racks waste gas.

Keep your vehicle in top shape. A poorly maintained engine can cut gas mileage by 10 to 20 percent. A clogged air filter can cause up to a 10 percent increase in fuel consumption. Underinflated tires require more energy to roll and can reduce fuel economy by 5 percent. Follow the maintenance schedule in your owner's manual, and keep the tires properly inflated.

Drive smart. As much as possible, avoid hard acceleration and braking. Once up to speed, maintain a steady pace in top gear; varying your speed a lot wastes fuel. A vehicle's gas mileage decreases rapidly at speeds above 60 mph. With most gasoline engines, it's more efficient to turn off the engine than to idle for any longer than 30 seconds. If you have air conditioning, use it sparingly.

Tweetha...funny how they dont mention any german cars????

[jipped genes]

Tweetmy car is pretty close and i could make the #s on the sticker if i could keep my foot out of it

[T-Man007]

TweetYeah, neither of our cars made the best or worse but I know for a fact that my car is very close. Since I'm self employed I keep up with all my milage and expenses and even with a heavy foot at times my car is pretty close to what they told us when we bought it. But, 90% of the cars are wrong does not surprise me.

ha...funny how they dont mention any german cars????

That just means none of the german cars have the best mph for their class. LOL

[VveTTe917]

TweetSurprised they didn't mention the H2 as the worst. Mine gets like 10mpg. I don't even drive it anymore since it will cost like 70 bucks to fill it up.
