I have drivin 500 miles in my 22 Sle 4 banger and this engine is snappy and responsive. However the Jury is still out on the MPG so far I'm only seeing maybe 22 -24 racing around town, was getting bout 19 - 21 in my V6 Slt so we shall see how a road trip plays out!! Yea so far ride ride and handling is great!I'm not sure how pleased you will be with the 4 cylinder MPG. My last Acadia was an '18, AWD 3.6. When the lease was up last year I opted to replace it with a '21 Buick Envision with the 2.0T. The Envision is much smaller than the Acadia.
Surprisingly, the 3.6 Acadia and the 2.0 Envision get about the same MPG both around town and on the highway.
I also have a Corvette, an '84 that likes 93 octane fuel.........fill ups are painful......but the fun factor when driving it quickly numbs the pain.
