How's everyone's hybrid MPG stats looking lately?
2025 Trail Hunter 13 months in , around town 17.1 MPG average. Out on the highway between 14.1 MPG and 15.5 depending on the wind. Considering speed limits in this area are the highest in the nation, 80 and 85 mph. Best I've gotten was 20.1 in the Navajo Nation in New Mexico where the speed limit is 55.

You're using premium fuel? Is your engine knocking? You don't get better gas mileage from premium.
I do, and don't think I ever said it will increase mileage. I am using it as a personal preference, that is all. I definitely don't need to debate it.

wow, you get really crappy mileage...

I still consider it a win, my Jeep Wrangler was only getting 12 and 1/2 MPG so anything better than that is good. Plus the trail hunter weighs a lot more than other models.

I wasn't trying to debate you, was just wondering if you were having knocking problems because that's the only reason you would use premium.

the extra 275+lbs, snorkel and more aggressive tires would make a difference, but damn... Still, better than a jeep haha

Right now, if my speedometer says 60, my actual speed is 58... if 80, actual is 77.
With larger tires, the speedo will show a LOWER speed than actual. Shows 60, probably doing 63 or so. Going from 33" to 35" tires will result in approx. 5% larger circumference resulting in approx. 5% speedo discrepancy. This will result in inaccurate mileage calculations. The computer will think you've travelled fewer miles and calculate a mileage that shows, for example, 19 mpg when its really 19.5-20.

Raising the vehicle 1-2" will increase the air turbulence underneath, especially if you've removed the front air dam. This will also decrease mileage.

The effect of the extra weight of the tire (within reason) is negligible compared to the taller/wider size tires and the wind resistance/turbulence effect.

I've been doing this for many years. Nothing like putting on 12 x 35's, 4" lift, adding skid plates, winches, batteries, air compressors, re-gearing, etc. to a Jeep CJ or Wrangler to absolutely kill the gas mileage on a vehicle that starts out with the aerodynamics of a brick.

Basically, just about any mods you do will lower mileage. However, some things are worth it. There's more to life than gas mileage.

Turns out that my speedometer discrepancy is more of a Google Maps/Apple Carplay issue. If I use the GPS speed on Google Maps using Carplay, the speedo reads appx 3% slower than the Toyota speedo. If I use Google Maps on my phone or iPad without routing through Carplay, the two speedos match. This makes sense to me with the larger tires... if it's true that Toyota sets their suv/truck speedometers a little fast to account for upsizing, stock vehicles should see slightly higher speed readings than normal, and larger tires (within reason) should actually be closer to accurate.

Glad you figured it out. On the other hand, I would be very surprised to learn that Toyota intentionally sets speedometers incorrectly from the factory. That sounds like a bad idea on many levels.

When I got my TH a year ago, I wasn't impressed with the mileage. I got a bit over 20 around town in Normal mode. Took a road trip last fall and I was down into the high teens. In the past 2-3 months, I've switched to Eco mode and just had my 15k service done and I'm up to 23.

Temperature matters a LOT. As it warms up, the Hybrid kicks in more. Eco might help but I am certain that cold hurts.

100% about the temp. I'm in AZ and MPG really takes a hit once it gets hot here and we need to crank the AC. That and if you're in the car a lot just parked and idling. The combination of the two keeps my avg down between 18-19 mpg even though my actual driving mpg is probably more like 22mpg.

Drove from Upstate SC to Marathon, FL. I have a TRD Pro, stock set-up with some extra underbody protection. Broke the drive up over two days. Used 87 and generally stayed 5mph over the speed limit on the interstate. Encountered a lot of stopped freeway traffic in the Jacksonville area on the way to our overnight stay in St. Augustine Beach. Three fill ups to get down. Each tank of gas was 21.2 - 21.5 mpg on the trip computer. The final fill up was in the Miami area before hitting the Keys. When I pulled up to our rental house, the reported mpg for the drive was 25.2 mpg. Started the trip with 4600 miles and did my first oil change prior to the trip.

I’m quite satisfied with that performance considering it was my wife, daughter and a fully loaded cargo space. Love the digital mirror.

Not doubting you but since the hybrid AC compressor is run by an electric motor, does it really affect the mileage noticeably. I realize that the gas motor has to create the electricity to charge the battery but there's no parasitic drag on the gas engine when the AC is used.

Yep. Unfortunately there's not a lot of battery capacity so anytime you're idling in AZ Jun-Aug, the electric motor can only go for a few minutes on its own (if that). The gas engine has to run if you want to keep the AC cranking. Definitely more of an issue for me because I do a lot of work from the car. It's not a huge effect on mpg while driving but a significant impact for the overall avg. I mainly bring it up because it seems like a lot of people watch that number on their dash gauge and of course it'll lower than just measuring active city/hwy driving on a trip basis vs including idling for long periods.
