Honestly, MPG?

Fed regulators are proposing a new method for estimating fuel economy for vehicles. Drivers have complained that current mpg estimates don’t reflect everyday driving.

The first change in 20 years to the EPA’s mileage test procedure will likely cut highway driving mpg for many models by 15%, and city by 20%. The EPA would add new tests that simulate high-speed driving, rapid acceleration, and stop-and-go driving in traffic. Also considered will be starting in cold temps, and running a/c in warm climates.

“The old system is broken,” said Jason Mark, director of the clean vehicles program for the Union of Concerned Scientists. “This is a good first step in fixing it.”

Gas-electric hybrids will be most affected, with city drivings ratings down by 20-30%
