Base models receive a new 2.5L 4-cylinder that produces 15 hp more than the outgoing 2.3L while also getting better gas mileage. EPA-estimated figures for the 2.5L engine are 23 city/34 hwy mpg for the automatic. The 2010 Ford Fusion also boasts an all 6-speed transmission lineup, apart from the CVT in the hybrid. The Ford and Microsoft developed SYNC system has been upgraded to provide automatic 911 dialing upon airbag deployment and custom Vehicle Health Reports.
