Fact #393: October 10, 2005
More Interest in Diesel Engines
On September 22, 2005, a survey asked the question:
Assume that a new vehicle you want to buy has two engine options that are equally clean, dependable, powerful, odorless, and smooth running. One uses gasoline and the other uses diesel fuel and gets 40% more miles per gallon but costs $2000 more. Which engine option would you buy?
This same question was also asked in July 2001. The results of the two surveys show that the interest in diesel engines with better fuel economy has grown. In 2001, 27% of respondents said they would choose the diesel option, but in 2005 52% of respondents chose that option.
