I lease a 2018 Malibu for $162.00 a month. This car has given me 32.4 mpg avg over this last year and over 40 mpg on the highway.

My aerocoupe averages around 8-9 mpg. Thats a 496 stroker, EFI, TH400, and 3.73 gears. Doesn't seem to matter how I drive it either which is cool.

Man you guys get horrible mileage😁.
I have given up on good mileage on this old junk and trucks. Our 2017 Challenger GT gets 35 mpg imperial doing 118 km/hr. Even in winter, 20 in town and 30 on the highway with 10% ethanol gas. I know it is less than US mpg but this a 4100 pound AWD car, so pretty good.
