I got a really high MPG calculation once in my Highlander, but not ever close to that again. I just assumed that the last pump where I bought fuel was a bit too eager to cut off when it was full. I never try to top off the tank to avoid issuers later.

 

Nice work. I've gotten that a few times, but only driving just over 60Mph. If flat and warm outside, no wind. This drivetrain combo will do really well. I took a trip south and put on over 1000 mi and avg'ed 28.5mpg. That was fully loaded with cargo carrier on the back driving 72 avg on interstate. I'd be curious to hear what "hypermiling" techniques you use on this vehicle?

 

Whew. I wish. The combination of my Highlander's 20" wheels and very grippy CrossClimate2 tires equal pretty rough fuel economy for me. I love the year-round traction those CrossClimate2s provide- but they come with a huge mpg penalty. I was able to get decent mileage with the factory 18" wheels and factory Michelin tires- but not with the CrossClimate2s.

 

I can do better with my 2023 Highlander Hybrid LE AWD. I still have my Nokia R 5 snow tires on too.
On a recent 50 mile round trip, I averaged 43 miles per gallon. Rural paved roads, average speed 50 mph.

 

I think the new transmission gearing helps a lot, as I've also noticed an increase, and I'm pretty heavy on the gas. But going 65-70 and the engine holding below 2,000 rpm is wonderful. My 2012 Highlander was revving much higher, so not much help unless I was going below 60...which doesn't happen in our area when most are going 70, at least on the slow lane.
