Less than one year ago the national average price for regular gasoline was $2.96 per gallon, and many consumers simply wrote off monthly fuels costs as a mere annoyance. Those days are over, according to a study released today by Edmunds.com.

Edmunds.com data shows that with gas prices at $4.06 per gallon there are 60 vehicles in the new-vehicle market that cost consumers more than $100 to fill.

In a separate analysis, Edmunds.com has also calculated that the median household is spending 11.5 percent of its income on gasoline expenses, up from 4.6 percent five years ago.

A look at historical household incomes and fuel prices reveals the degree to which fuel prices are affecting consumers' budgets:

¹ Energy Information Administration data

² US Census Bureau data. Last reported year is 2006; 2007 and 2008 income figures are assumed the same as 2006

³ Assumes 30,000 miles driven per household per year and 22 miles-per-gallon average fuel economy

As shown by Edmunds.com data below, the number of models on the market that cost over $100 to fill is on the rise.
