Amazing, Chevy builds a 330 HP engine with 28mpg Options

[Hawktel]

So the new Impalla that chevy has released has a option for a 330 HP V8 with 28 highway fuel consumption.

Thats amazing. Just amazing. I wonder how far fuel efficency can be pushed?

They are all liars!...This from Consumers Reports.

Fuel economy
Why you're not getting the mpg you expect

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.
