I mostly have been taking relatively short trips with my car since getting it but finally got out on a 900 km trek recently. When driving around town mostly I never noticed any difference between fuel economy ratings and what I was getting. But on the highway it was very different. I was seeing 10% or better improvements over the government ratings. That seems a bit crazy.
So, then I looked into it further and it seems I was getting very close to the rating for the 2WD 3.8 and not the AWD. So, I have a hypothesis. The driving simulator used to rate the car doesn't get the AWD to go into to purely RWD economy mode that you can get on the highway. When the car switches into that mode it is, for all intents, just a RWD car carrying around about 75lb of AWD gear.
Has anyone else noticed this phenomenon?
(Also, in researching it I discovered that the EPA tests the car in Normal mode, not eco mode. In the AWD normal mode has a 60:40 torque split but in eco it's 80:20, same as sport. Switching to eco would probably have raised the city ratings a bit.)
