Those are not the hybrid values. The same Canadian government site does differentiate between the hybrid and non-hybrid Tundras. I think the 2-mode and 3-mode 4x4 it lists are the full-time and part-time systems, but even that's odd because in Canada, we can't get the full-time 4x4 on any non-hybrid models. Maybe 3-mode is with rear locker? Also worth mentioning that 25 is highway mileage. 19 city, 21 combined.
