Tundra not the gas guzzler it’s made out to be.

    That’s what would be really cool for the new 2022 Tundra- mildly updated 5.7l with a 10 speed. But I know from watching Ram & GM with their 8 and 10 speeds that 4:30 ratio would have to go. Those trannies with 8, 9, or 10 speeds would be shifting way too often etc if you tried to keep the 4:30 ratio rear. Would be sweet tho!!

    I’d like to see a manual transmission offered but that’ll never happen.

    I don’t trust the computer mpgs. Maybe they are pretty accurate in the new trucks. You’re right though, pretty good mpgs for a truck with a 5.7l engine with no stupid start stop features.

    A GM homer told me the 10 speed paired with the 3.23 rear end has a lower first gear than our 6 speeds with the 4.30 rear end.

    18 is average for me on the hwy and that seems pretty decent as both my previous 4Runners would do around 20. Small price to pay for Crewmax space and a iforce v8:burnrubber:

    That is very true. And second and third gear too. However all things being equal a lower geared rear is tougher and longer lasting. Our trucks are in the middle of the 1/2 ton pack on final ratio at the rear wheel. And the again, go look at the rear of the 3.23 and compare the beef to ours.

    There's really no reason a 10 speed tranny can't be geared to work great with the 4.30 gears. I'm no expert but seems to me that a 4.30 axel just makes everything in front of it work with less strain.

    I think the big 3 exaggerate their advertised mpg. Tundra seems to be more real world expectation. Perfect example was my wifes f150 ecoboost. It would get 12.0 city and 15 highway 2wd 275/65r18. I never saw better than 16 in that truck. My tundra I get 14 or so mixed and when I drove it to Texas from Utah saw 19.8 mpg 70-80 the whole way. Probably don't get that anymore with the 33s on it but still better than that ecoboost used to be. I will say my gmc was great on gas though it was lowered. 16 city , 22 highway with a 5.3 lt v8

    It also was rcsb 2wd

    Forget the manufacturer numbers, they're not really in control there. The government runs each vehicle through a gauntlet of tests.

    But Fuelly should tell us the real numbers. Yes the newer F150 has somewhat better MPG but it's not like Tundra=15 and F150=30.

    The pics:
    1) All F150
    2) 2021 F150 (should be the 'best', right?)
    3) All Tundra
    4) 2021 Tundra

    The EPA tests are a joke. Their "highway" test is done at 48 mph, if I recall correctly.

    Sounds about right with the MPG you’re getting. I was doing about the same commute as you are, 50 miles south, and 50 miles north.

    Was averaging anywhere between 17-19mpg taking it between 55-65mph.

    Anything above 65mph would be roughly between 14-16.5mpg.

    However, not to hi-jack threads, but what ranges are we Tundra owners seeing?

    At first, I was seeing 350+, now after filling up, I’m seeing about 320-325 range.

    This is for the 26gal tank btw and not the 38gal tank.

    Miles per tank means nothing to me. I only care about mpgs.
