Toyota Tundra III CrewMax: A New Generation

The Tundra has historically been Toyota’s entry into the highly competitive full-size pickup segment. Previous generations, while reliable, often lagged behind competitors in terms of features and performance. The third generation, however, aimed to address these shortcomings with a comprehensive redesign. The “i-FORCE” branding signifies the powerful V6 engine under the hood, and the “ECT-i” denotes the electronically controlled transmission with intelligence, optimizing shift patterns for both performance and fuel economy. This model year represents a pivotal shift for the Tundra, moving it towards a more modern and competitive position in the market.
