Two Pickups with some similarities, but otherwise different in most aspects such as the horsepower, starting price, fuel economy, ground shadow size, height, and maximum occupancy.

Also, the 2016 1500 Regular Cab has a more powerful engine than the 2015 Frontier Crew Cab, but it gets 1.2 more miles on a gallon of fuel. In addition, the Frontier Crew Cab body is slightly smaller than the 1500 Regular Cab, and in addition to that, it's also shorter. And finally, you'll seat one more passenger in the Ram 1500 Regular Cab than in the Nissan Frontier Crew Cab. Among similarities is the body structure.
