Two Pickups with some similarities, but otherwise different in most aspects such as the model year, horsepower, and maximum occupancy. First of all, the 2017 Ridgeline produces fewer horsepower than the 2013 2500 Regular Cab. Also, there is a difference in the number of passengers; the 2500 Regular Cab seats one more the Ridgeline. Among similarities are the body structure and starting price.
