This is the most comfortable-riding full-sized pickup on the market, yet the Ram is also plenty capable of grunt work. Its coil-spring rear suspension helps cushion the ride, and the spacious cab is luxury-car quiet. Our Big Horn Crew Cab, with its smooth 5.7-liter V8, averaged 15 mpg. The base 3.6-liter V6 is no weakling, but it tows less. The torquey 3.0-liter diesel V6 version is expensive but delivers effortless thrust and returns a class-leading 20 mpg overall. Rear-seat room is generous, and the Uconnect 8.4-inch touch-screen infotainment system is easy to use. Reliability has been well below average.
