. The automatic gets 21 city 24 highway combined 22 vs 17 city 23 highway 19 combined for the manual. Are these numbers accurate? When I had my 2018 wrangler (manual) I was averaging 21

I would say no as I get better mileage than that with my 8sp auto. And I've owned vehicles that got worse mileage than the published ratings.

YMMV... actual mileage is predicated on a lot of variables. Published mileage ratings are established under CAFE standards and EPA testing.

CAFE standards are calculated by a production-weighted average of mileage ratings across a manufacturer's fleet.

The EPA tests to establish, and verify, mileage rates for a manufacturer. Vehicles can be tested at a top speed of 80 mph in order to calculate the highway mpg estimates. EPA utilizes five test cycles to represent real-world driving conditions and there are tests designed and conducted to simulate stop-and-go city driving, high air conditioning use, and driving in cold temperatures.

However, they are simulations only and do not accurately account for how a person drives, differing throttle inputs across a population or a number of variables that are not tested in the lab.

It boils down to what you actually get with your vehicle with you in it. One (1) MPG either way is a neglibile variant IMHO.

I'm often occupied, by many things, often at the same time
Yeah, they're accurate.

In the hands of real people, the auto will get better mileage. People with manual tend to get lazy and not shift as often and lug the motor. The auto shifts smooth and fast.

After all it is hard to surf the web, post on Facebook and look at the Gram while shifting 50 time manually in the miles.
