Also, the 2015 Titan King Cab has bigger and thirstier engine; the 2016 Frontier Crew Cab gets 3.5 more mpg. In addition, not only Frontier Crew Cab is significantly smaller, but it's also slightly shorter than the Titan King Cab. And finally, you'll seat one more passenger in the Nissan Titan King Cab than in the Nissan Frontier Crew Cab. Among similarities is the body structure.
