What about the Mazda 6 based 2010 Ford Fusion 2.5L 6spd auto, 23/34/27mpg - http://www.fueleconomy.gov/feg/2008car1tablef.jsp?id=26406fuel economy for the 2.0L version is nothing to write home about at 24/30, but 30 mpg is really the point of diminishing returns in the economic sense
The hybrid version is supposed to be the most fun to drive hybrid (beats the Camry Hybrid by 5mpg too), but I doubt its worth the price premium over the regular version...
