Sounds about right - at 56 it was probably just slightly above what a cold idle would be. The overdrive capabilities of the CVT are unmatched.Oh and before I forget.. I got 52 mpg (yes!) on a 105 mile desert highway drive, mostly with the cruise set to 56 mph in a 2021 Nissan Altima or me really feathering the throttle just to see what it would do in mpgs, when I saw hills where my foot would get better mpgs than the cruise control.
Halfway thru the drive I was at 56-57 mpg but then a stretch with more mild hills showed up and lowered my milage.
Newest Sentra looks quite handsome - guessing they improved the performance as all the last generations I have had as rentals were slow slow slow. I'm still not entirely convinced of the JATCO CVT reliability - still seems hit or miss even in their most recent iteration. I would keep it serviced above and beyond what Nissan recommends.My wife’s 2020 Sentra gets 43-47mpg ac on 70+mph hwy cruises. Nissan has a great cvt not knowing you’d think it’s shifting gears. Plenty of pep handles well good infotainment and hvac controls. Only hiccup we have is the backup cam intermittently doesn’t work. “Got to schedule a service” otherwise Nissan makes a great vehicle.
