I took my 2018 A10 ZL1 to NJ -> FL > NJ 3K miles a mixture of highway and local driving 33% local 66% highway and averaged around 26 MPG. DI and lighter weight makes a big difference. Still deciding whats next. As for my 2015 ZL1 the gas mileage and Recaros were the only detractions for me of the 5th Gen Z. Still it has a presence missing in the SS.

The only time i see double digits is on the freeway. Most of the time I get single digits. Most of my driving is around town.

Hmmm... I wonder if it has something to do with the fuel, then: in Europe we rarely have stations with 100+ octanes (RON), which is equivalent to 95.5 ((R + M) / 2) in the States... Therefore I put in 98 RON octanes which comes to 93.5 (R + M) / 2... maybe that's why I can barely get 19 MPG when hypermiling?

Would 93.5 octanes even be considered "premium" gasoline?

Yes. 93 octane is premium here.

Thats about where I am with 650 RWHP
I've seen 22 with the cruise control driving down the highway @ 65 to 70 but thats for like a minute LOL...
90% of my driving is 12 to 14 MPG and I basically fill it up every other time I take it out, AND IT'S WELL WORTH IT

Not to burst everyone bubble, but those calculators in the display aren't always correct. I've had some of my cars off by 3 mpg. I usually just fill up to the first click, reset the mileage trip odometer, run it out, then go back to the same pump and fill up to the first click again then do the math, mileage divided by gallons. Haven't done it on the Z because my right foot makes my milage horrible so never saw the point.

I did exactly that, and the first time I did it, the on-board computer was off by 0.6 L / 100 km. The second time it was off by 0.2 L / 100 km.

Since the sample size is small, I need to do more measurements to get meaningful data. Then I will calculate the standard deviation and the median.

I'm curious as to how (im)precise the on-board computer is. I drive mine on long trips all over Europe with significantly cheaper or more expensive fuel prices (and sometimes of dubious fuel quality, or at least I don't trust it!) that knowing the precision of the range calculation is valuable to me, since I might be able to use that information to skip countries where I don't trust the fuel purity, or where the prices are too high.

Old school way. Fillup take trip miles on tank and divide for me. Works every time.
