Here are the EPA ratings for gas/electric hybrid vehicles. As you can see, the real-world mileage figures that Your MPG drivers report are often lower than the government combined city/highway rating, and that's using the current test methods. Meanwhile, diesel owners usually report mpg averages that are higher than the combined rating. The EPA expects hybrids to take the biggest hit when the testing methods are updated later this year because the current tests favor the speeds at which hybrids are most efficient.
