I wonder what the mpg figures are, I could only find "30 combined," which doesn't seem very impressive. Our '18 Mazda 3 will knock down almost 40 on the highway, has a plenty decent N/A 2.5 engine with 185 hp and 184 tq (although not over that large spread.
If Mazda can make big naturally aspirated cars with that kind of mileage. My ex-wifes Mazda 6 Grand Touring with the e-package was rated at 40 on the highway and did better in real life, with the same NA 2.5 4 cylinder.
Certainly Honda/Acura can build a more efficient NA engine to get the same mileage without the added cost, weight, and complexity of a turbo.
