The 2.5-liter inline 4-cylinder gas engine and permanent magnet AC synchronous electricmotor in the MKZ deliver 191 net horsepower, a modest amount ofpower for a 3, 752 lb vehicle.
Essentially leveraged as a form of high-tech turbocharging, here a small electricmotor gives a modest fuel-free power boost to a direct-fuel-injected 2.4-liter four-cylinder engine.
