My dad has a much less-known hybrid, and it's in fact the most fuel efficient car in the United States.
"According to the EPA, ... Insight was the most fuel-efficient mass-produced automobile sold in the United States...."

"The Insight earned an EPA mileage estimate of 70 miles per gallon in highway driving, 61 mpg city."

It's not the best looking car ever, but he drives quite a bit to work every day, so he loves it.
(People always ask him how many mpg it gets, and how long you have to plug it in :P)
