Two Pickups with some similarities, but otherwise different in most aspects such as the model year, starting price, horsepower, ground shadow size, and height. First of all, there is a $3,550 difference in the base MSRP. The 2016 Nissan Titan XD, a newer vehicle by three model years, has a higher starting price than the 2013 GMC Sierra 1500 Crew Cab. Also, the 2016 Titan XD pulls more horsepower than the 2013 Sierra 1500 Crew Cab. And finally, not only Sierra 1500 Crew Cab is slightly smaller, but it's also shorter than the Titan XD. Among similarities are the body structure and maximum occupancy.
