230 miles per gallon were intended to be within the Chevy Volt, with first GM estimates. The government formula that was used to calculate this number, though, was never officially approved. This means the estimation of miles per gallon for most hybrids will have to be recalculated — not just the Chevy Volt.
Hybrid mpg calculation
Hybrid calculations of mileage were hard for the EPA to figure out. Miles divided by fuel is how “real” miles per gallon is calculated usually. However, the EPA estimates of mileage are more complicated. The mileage changes based on city driving, highway driving, and maintenance. The formula also has to change considering the numerous different variables of hybrids. In order to get an accurate estimate of the mpg a vehicle will get, the EPA uses relatively complicated formulas.
Chevy Volt difficulties with calculation
In calculating the mpg rating of the Chevy Volt, GM used a formula created by the government. The formula never hit “final approval” if you ask the EPA. 230 miles per gallon were intended to be what the Volt got as they stated when selling. ”Working collaboratively,” the government and GM came up with a new formula. It is likely the Volt could be rated at between 70 and 140 miles per gallon, depending on the new calculations.
Electric needing to be balanced too
Regulators have always had a hard time with electric cars. The fluctuation of energy and fuel make comparisons with money hard to do. Electric cars can’t apply miles per gallon. It is nearly extremely hard to determine considering the mileage of a hybrid is affected more by variables like habits while driving. The EPA is trying to answer this question though.
