The word “powerful” is the most appropriate when qualifying your definition for Toyota Tundra. There are two powerful i-Force engines to choose from. The larger is a 5.7L V8 for all-out power, and the other is a 4.6L V8 for better efficiency. The TRD Pro model has the 5.7L V8 under the hood.
Both engines feature Dual Independent Variable Valve Timing with intelligence (VVT-i) to optimize engine breathing for maximum power and efficiency. The Acoustic Control Induction System automatically adjusts air intake runner length with a valve that changes the air flow routing. This optimizes the air flow pressure at different engine speeds. The end results is 381 horsepower at 5,600 rpm and 401 lb.-ft. of torque at 3,600 rpm, with a fuel economy of 13 mpg city and 17 mpg highway for a combined 14 mpg.
