I notice with our 09 Limited AWD, it's very easy to speed and accelerate, the engine is very well tuned and has lot of power. On our trip from up north in the summer I drove very easy on the pedal around 90 to 100KM/h, just to see what's the best mileage possible. The computer calculated consumption was 8.4 l/100km. We had 20,000km on the car and I think that's why. I think it takes long time to brake-in the engine.
