Toyota just hasn’t been able to crack the huge full-size pickup segment. Like Japanese rival Nissan’s Titan, the Toyota Tundra has simply failed to dent a segment still dominated by Detroit. But the industry giant is determined to gain some traction and will roll out its latest weapon when it reveals the new 2014 Toyota Tundra at the Chicago Auto Show next month. Beyond confirming the introduction, the maker is revealing nothing, no hints about styling, payload or performance and definitely no teaser images. In fact, there have been few of the normal spy shots making the rounds, underscoring Toyota’s apparent determination to take the industry by surprise when the next-gen truck is unveiled.
