Default 30mpg

On the way from Vegas to Orange County yesterday, 30mpg. Not bad for flowing with the high speed traffic. The 68mph average included crawling out of Vegas and a food stop.

I'll assume that the resulting MPG was from coasting feature kicking-in? I think I've seen similar on longer road trips.... 68 MPH average however I'd have a hard time hitting that low! LOL

I expected the coasting feature to kick in but it didn't too much as the traffic was flowing around 80mph

I see 29 to 30 mpg routinely on road trips.

Man these cars are awesome! I’ve been curious, has anyone checked to verify that actual mileage matches with the computer estimates? Is it dead on or is there a slight discrepancy between what you put in the tank and calculate manually versus with the computer shows?

I usually see 25 MPG when traveling at 75 mph. I think I have seen 28 once or twice when traveling at lower speeds. This is in a 991.2 Base Cabrio.

I've seen 28-29 mpg on highway at ~75 mph with a 991.2 GTS coupe manual (7th gear).

I have a 2018 S
I drive 95 miles to work. Set the cruise at 78mph.
Where I live the elevation is 777' above sea level. Where I work it is 1026' (I know the elevations because I am a pilot. Obviously that is sort of strange to know. haha)
Driving uphill to work albeit a very slight grade I get 29mpg pretty consistently. Driving home (downhill) I get 30.5 mpg.

The only difference from going to work to coming homes is the elevation. I find it interesting it has that much affect on mpg.

Mine seems to match the calculated MPG, at least within 1 or 2.

Yup, the whole reason for smaller displacement and turbocharged engines! My buddy's 997 struggles to get 26mpg on the highway.

2018 Base C2 here. 25 mpg in mixed driving (lots of Chicago traffic). 30-31 mpg on road trips (cruise control between 80-85 mph). 3.4 mpg on the track
