Let's see, in this thread:
OP immasecretninja drove his new 2017 AWD CX-5 975 miles and has average MPG at 18.3.
Dimcorner drove his new 2017 AWD CX-5 500 miles with 90% city and has first tank MPG at 22.5.
paging_drburgos drove his new 2017 (FWD?) CX-5 mixed and has average MPG at 25.1.
Pipemajor drove his new 2017 AWD CX-5 for a 280-mile road trip at 900 miles and got average MPG at 31.9.
EPA estimated MPG for 2017 CX-5 FWD is 27/24/31 and AWD is 26/23/29 combined/city/highway. Based on these samples your conclusion is those 2017 CX-5's pretty much hit / exceed EPA numbers? Or you only based on Pipemajor's one sample who got the best fuel efficient SA-G engine among them?
Why resetting the average MPG has anything to do with the poor MPG readout? Those brand new 2017 CX-5's all got fresh start on those computer settings from factory. The average MPG is from factory to current.
New engine may use more gas? What happened on Pipemajor's brand new engine then? (uhm)
I have to agree with Unobtanium though. This's the second time Mazda has lowered EPA ratings for 2.5L CX-5 after Mazda raised EPA ratings for 2016 CX-5. The latest ratings seem like closer to the reality.
