Just read this about the 2013 Ford Fusion SE Hybrid
"EcoCruise control saves vehicle energy by slowing down acceleration compared to standard cruise control. Your vehicle may temporarily lose speed when going uphill. It can be switched on or off in the information display"
Looks like the new hybrid version is projected (by Ford) to get 47 city and 44 hwy mpg. A 2 liter Atkinson-cycle four cyl, paired w/ an electric motor, makes 180bhp and 130 ft lbs of torque. Vehicle has an estimated Cd of .27
