It’s getting harder to find a mid-size family sedan that still offers a V-6 engine under the hood, and with good reason. Today’s turbocharged four-cylinders can match yesterday’s six-cylinder units in the power department while providing much more palatable fuel mileage. The 2013 Chevrolet Malibu (MSRP $26,715) is the latest four-door sedan to receive the turbo treatment, and we were on hand to drive it this past week along the twisty roads that carve through the hills of Northern California.
