Last year, Town & Country shoppers had a choice of three V-6 engines, but for 2011 all models are powered by a 283-horsepower, 3.6-liter V-6 that teams with a six-speed automatic transmission. This is Chrysler's new Pentastar V-6. It's used widely in the automaker's lineup, and it feels strong enough in this van. The automatic shifts smoothly, and the drivetrain gets an EPA-estimated 17/25 mpg city/highway on regular gas. The minivan also includes an Econ mode that improves gas mileage by altering the transmission's shifting behavior.
