Assume the same driving styles done for both Tour and Sport modes, should you get approximately the same gas mileage for both or will Sport cause any lower miles per gallon than Tour? And, if lower, why?
Interesting! Explanations anyone?I have done a mileage test between the sport tour and eco on two trips back from Florida. In both test running on cruise at 80 I got my best gas milage in the sport mode. and it wasn't even close between the eco and sport mode. Averaged 1.7 mpg better in sport over 400 miles.
Interesting! Explanations anyone?
Hypothesis: exhaust back pressure. In Sport mode with the performance exhaust package, you should experience less back pressure when all 4 pipes are opened.
Test: turn off the active sound management in the menus (decouple from driving mode), drive in Touring or Eco, see what you get.
