High speed fuel economy

I took a 240 mile trip last Sunday and did it at an average speed of 80 MPH. Basically 75-85 mph as the speed limit was mostly 80 mph and conditions nice, zero stops, in about 2 hours 45 mins. The car a new 2022 Hyundai Sonata hybrid.



Was pretty happy with 42.5 mpg calculated at the pump, the car said I was getting 43.2. There was 1200 feet of elevation gain start to finish and there were winds of 5-15 mph but not a tail or headwind. The trip back I slowed down about 5 mph, had the downhill and similar wind and got 44.5 mpg at more like a 75 mph average while driving but stopped once along the way.

Pretty happy. What's the best 80 mph average others have gotten? Even the TDIs seem to drop off pretty hard after 75 mph. My ev mode would kick on and off even at 85 mph so that was cool.

Yeah .24 cD!

I was just reading your thread, you were already talking these 80 mph speed limits. I'm just up from you in Montana. My only mod so far was to put the tires at 43 psi.

I did shop both the Sonata, Elantra, and Ioniq hybrids but liked them size and looks of the Sonata and the prices are all really close.

Mine is that pearl white and the accents are all black.

I suppose a 1.9 TDI swapped 1st gen Insight with long gearing should do insanely well at that speed.

First gen Insight gets ballpark 55mpg at that speed. In my Insight with a TSX engine (runs an 11 second quarter mile) I'm still getting around 42mpg at that speed.

Montana is my dream state to live in but itís so expensive. By far my fave place. Especially west Montana. Bozeman. Missoula. Glacier. Flathead lake. All from like another planet. Psi and rolling resistance doesnít matter at highway speeds I found out. Swapped my 38 psi blizzak snow tires to 45 psi ecopias and itís the exact same mpg going over 80mph. Now City driving is completely different w though

Nice car look and pearl color. Although I prefer metallic or plain white. Because pearl is expensive to paint. Show a photo of the trunk to see if there is a small cargo opening.

I'm sitting around 125 mpg-e at 80 mph on summer tires. Snow tires kills it a little. But MPG-e is a mostly useless metric when comparing to fossil efficiencies. 46 is pretty good for a hybrid!

Can't wait to get an Aptera and be around 300 mpg-e...

Are you taking charging losses into consideration ? And those would vary, depending on the charging infrastructure. 115-VAC vs 220-VAC etc..
