Trailhunter MPG

[TacoFreak]

That’s essentially my setup minus the tires and I got 17.5 l / 100 km (13.4 mpg) on my last 850 km of highway driving. Makes me think something’s wrong with my truck.

Yeah, I wonder about the same thing with my Pro. Although I have gotten higher mileage than that, it is probably very close to my highway average. When I drive it on the curves and hills of the Appalachian mountains where I live, with long grades that let it run on battery, I can get over 20 mpg. But just straight highway without any real chance for the hybrid system helping much, I never get over 18 mpg.

I also thought there was something wrong with my truck, but I am starting to think that it might be normal for these trucks. Highways have never been where hybrids shine, and our trucks seem to prove that.

I don’t see my battery kicking in all that often around the city honestly, and if it does it is for a short blast and then off, like seconds. I completely accept that this truck won’t get 10.3 l / 100 km, but my old gas guzzling 2006 taco with a V6, lift, arb number and winch, etc., got 15 l /100 km. Pretty sad when the 2024 inline 4 can’t do similar. But, it does have 100 more HP and double the torque.

All in all, if I assumed I was going to get say 13 l / 100 km, and I’m actually getting 16 l / 100 km. That’s 3,000 additional liters of fuel per 100K km. If the truck lasts 400K km, that’s 12,000 liters or ~$21,000 additional cost. Worth making a little noise about.

Totally agree. Making noise is really all we can do at this point. Either Toyota somehow faked the EPA mileage numbers or there is something wrong with my truck too. But a lot of people are only getting what are, so it seems like we have a lot of company.

EPA tests are useless these days unless you are very aero.

Look at the test schedule: https://www.fueleconomy.gov/feg/fe_test_schedules.shtml

Highway doesn't get above 60 and it averages 48.3mph. Who averages that speed on the highway?


Oh, they do a high speed test. oh wait, thats useless too, it only goes above 60 for 30 seconds and the average speed is still 48 mph. who does that on the highway? how is that "high speed"?

So, I bet you Toyota does optimize for the test as much as they can, who wouldn't, but the EPA test are basically useless. Speed limits aren't 55 anymore.

Driving 65mph steady should get you around 22-23 in my experience so if you dont get that, something is probably wrong..

The interstates near me are mostly posted for 70m mph and a few mountainous areas are 65. But if you drive slower than 70 in either zone you are a rolling traffic hazard. You would need to be in the right lane with the trucks with your safety flasher on. My average is probably 73-74 mph and that gives me 19 mpg at the very best.

I will discus this at my next service appointment but I expect to be told it is normal for my truck. Some trucks seem to get the advertise mpg, but many don't. The info from @timetoeatpotatoes about the test conditions makes it hard to understand how anyone can get those numbers. You can be ticketed for going those speeds in many locations.

So I have been disappointed too with MPG. I have Prinsu, KUAT bedrack, Decked and a Weboost antenna that all incorporate drag to the outer mold line. I did an experiment where I went on a long trip and calculated MPG by the odometer. I found that was getting about 80 miles per quarter of a tank with a total of 320 per tank without tapping into the full reserve. I had about 15 miles left on the traditional “miles left gauge” that I have found hasn’t been totally accurate and does calculations in real time. I have about 7500 miles so far. The TH is legit in off-road settings and the compressor and inverter work as advertised. The Decked system is a must and was an easy install too.

can you share your weboost setup?

I did 65 from TN to Moab and best I got was 19.. Mostly 16-17.. Using Fuelly App to check because dont trust the Toyota App in truck,, Nor the gas gauge..

Unless you are stock, dont idle, and drive exactly the same way I do it's tough to make a direct comparison.

You've got wider tires, a cap, and rack, right? and if you were headed to maob my guess is you were loaded to offroad. Things make an impact.

I never read the specs on the EPA test conditions before. It is not a surprise that no one is getting the sticker mpg because no sane person would drive that slowly on a freeway. I would think that you might even get a ticket for obstructing traffic at an average speed of less than 50 mph, and I know it wouldn't be safe.

I have never tried staying at 65 mph, but at 70-78 mph I get up to 22 mpg.

I took a day trip over Chinook Pass (5,430 feet) in Washington last weekend, that was my first tank at 20 mpg. Previous best was 19.2. I was getting 14-15 when I first got my truck in November. I am at 5,500 miles. It is getting better
