3. Lincoln MKZ (45 mpg)
The most fuel efficient hybrid on the list is the new Lincoln MKZ. By getting 45 mpg combined, the sleek and luxurious MKZ is sure to be a hit, if buyers can get their hands on it. Sadly Lincoln is dealing with some production issues and setbacks which puts the MKZ out of mind for now. When Lincoln finally delivers the MKZ, buyers will have to see if that 45 mpg mark is an easy target to attain. Discuss this one more at our Lincon MKZ Forum.
