There are no substantial updates under the skin of the 2014 Toyota Tundra. The interior is much more user friendly with higher grade materials throughout. Exterior updates are most noticeable from the front end, where everything is squared off. A three piece rear bumper is new and "Tundra" is stamped into the tailgate.
It still does not come with a built-in brake controller, something that most competitors are doing, and the overall towing/load ratings remain the same. In fact: engine, transmission and gearing choices remain the same. Still, Toyota did manage to add a little spice to the 2014 Toyota Tundra in its overall character.
Just a bit.
We did get a chance to compare the 2014 Toyota Tundra to the 2013 Tundra - directly.
