At just shy of 3000lbs, I’d think that little turbo 2.0 would offer you better numbers at 70 mph.
As a comparison, my 2016 Jeep Grand Cherokee SRT is 5200 lbs, all wheel drive, running a 475hp 6.2 hemi with wide performance tires. At 70mph I get between 25 and 26 mpg(while running in Eco mode (4cyl mode) CD is reportedly .371.
It’s absolutely dead factory stock. I would expect your GTI to get noticeably better mileage than my Jeep muscle car SUV.
Is it possible your car is out of tune somehow? Tired spark plugs, etc. It would be great if a minor tune up service could unleash hidden mpg for you.

It is a quite fun little car. I weighed it with myself and a full tank of gas not too long ago, its 3200lbs. I'm not sure where the 38mpg comes from in that review, the EPA rating for a 2012 GTI is 24/33mpg, 27 combined (the auto is a DSG, it gets better mileage than the manual trans). I am due for a little bit of maintenance, spark plugs have 56k miles on them (60k change interval), and the intake valves/manifold I'm sure are ready for a carbon cleaning: I'm not getting any CELs yet, but I'm at 96k total miles and its never been done.
Interestingly, my car, with the gen 1 EA888 engine and 6-speed, is rated for 27mpg combined, while the 2021 GTI with the gen 3 EA888 and a newer 7-speed version of the same transmission, is also only rated at 27 combined (24/32mpg city/highway), although I know people with that car routinely getting 35mpg or better on the highway. As for me, on flat ground I get about 30mpg at 65mph and about 28mpg at 70-72mph. I've manually checked the mileage on every fillup for 5 years, and found the built-in mpg calculation to be consistently within 1MPG of actual usage.
