An Intellichoice.com survey compared the 51 clean diesel and hybrid vehicles to their gasoline equivalents and found that 35 of them have a lower cost of ownership. The increase in sticker price was more than made up for in decreased fuel costs, tax incentives, lower maintenance costs, and a higher resale value. If the price of gasoline went up to $4.00 a gallon, 41 would have a lower cost of ownership.
