Does the 2025 Tundra with its new 10-speed transmission really consume less fuel than the 2024 model's 6-speed box?
Yes, the 10-speed automatic paired with the 5.7L double-turbo V6 improves fuel economy by 8-12% in mixed driving versus the 2024 Tundra's 6-speed transmission. On the highway at 100 km/h, a 2025 Tundra 5.7L twin-turbo shows average consumption of 9.2 L/100 km compared to 10.1 L/100 km for the equivalent 2024 model. This improvement is especially noticeable in city driving where the extra gears reduce engine loafing at lower speeds. However, premium fuel (91 octane minimum) remains mandatory, and real-world consumption depends heavily on driving style and terrain configuration. Winter driving will see consumption increase by 10-15% compared to these baseline figures.
