Comparing fuel efficiency gains for a Jeep, a Camry, and a Civic

Richard Larrick, who guest blogged for us, points to a graph from The Green Grok showing gas money savings for mpg improvements over 1,000 miles at three fuel efficiency levels. They equate to driving a Jeep SUV (red), a Camry (blue), and a Civic (green). The figure assumes $4 per gallon gas.

You can also watch Larrick and co-author Jack Soll in this spot produced by Duke University.
