    I think we're forgetting how good a combined 25 mpg would be for the Tundra Hybrid. Just to put this in perspective, my Acura FWD Acura RDX gets a combined 24 with a 2 liter turbo. A half ton truck getting better mileage than crossovers is still a feat, even if it's not 30 mpg.

    Toyota non hybrid - 32 gallons

    Ford 3.5 EcoBoost or 5.0 V8 Coyote - 36 gallons

    Yes, disappointed.

    Also, I don't think those hybrid systems will do much to increase range for highway towing.

    If it's a 32 gallon tank for TRD Pro and can get 25mpg Hwy that is 750+ miles before fill up which is pretty effin awesome. If I could get 15-17 towing my UTV and trailer (~4,000lbs) that is still over 500 miles. My current 5.7 hemi will barely crack 250 miles to a tank towing (24gal). I don't know why everyone is so hung up on this, GM doesn't even offer bigger tank options on the Trailboss or AT4. 99% of Rebels available are either a 23 or 26 gallon tank with archaic 5.7. There is Ford and their current string of quality I don't even pay attention to them unfortunately. Really the only 1/2 ton that really might offer more range is the small diesels since you can get a 33gal tank in the Ecodiesel Rebel (likely my 2nd choice of truck) but they are gutless...

    I wanted a faster vehicle so I also bought a Chevy SS... because 4 door sedans with big V8’s are hilarious.
    We could just use a very unscientific method to extrapolate this.

    If the goal was to provide equal range to the outgoing 38 gallon tank the math is pretty strait forward.

    Current truck is getting:

    13 MPG City X 38 gallons = theoretical range of 494 miles.

    17 MPG Highway X 38 gallons = theoretical range of 646 miles.

    15 MPG Combined cycle X 38 gallons = theoretical range of 570 miles.

    So Toyota would need the new base iForce powered Tundra to do 494/646/570 miles on a tank depending on the cycle, except with only 32.2 gallons.

    Those numbers come out to only needing to achieve:

    15 MPG city, 20 MPG highway, and 18 MPG combined cycle. (Numbers rounded to the nearest whole gallon)

    So Toyota doesn’t have to hit a super ambitious goal to equal the range of the current Tundra. I would like to think they can do better than that. I don’t know how much the current 38 gallon tank holds in reserve before the fuel light comes on, in my trusty old 2007 with its puny 26.4 gallon tank the fuel light comes on at about 19 gallons burned. Maybe the goal Toyota has is to equal the range of the current Tundra until the low fuel light comes on? Someone post up how much fuel that is and re-run the numbers if a 6.5-7.5 gallon reserve is what Toyota wants for fuel pump cooling.

    The only challenge with this is every gas engine gets 10 mpg or less when towing.

    Towing near max I’m sure that’s true, but as a variable there’s almost no way to control for that.

    Depends on how much and what your towing. I consistently get 13-14mpg towing a UTV and trailer + gear (4,000lbs) over PNW mountain passes in a 5.7 Hemi. It gets about 8mpg towing a 26ft 6,500lb travel trailer over the same pass. Flat ground I can net nearly 12mpg. Conversely, I can tow that same amount of weight in say 2-3 cords of wood and still get 13-14mpg (less drag). That engine is nowhere near overly efficient. Actually, the new 6.2 does better in the GM. I can tell you most of the new modern V8's can easily get above 10mpg or more depending on what your towing. Funny part is the 3.5 Ecoboost in our group of friends consistently gets the least while towing. It's great having the most power but 20mpg quickly turns to about 6mpg once you add even a small trailer.

    Ultimately, where I'm going with this is I'm not fully convinced the 3.5TT here in the Tundra while loaded all things being equal will get much better mpg than the outgoing 5.7. I do however expect depending on the implementation of the hybrid setup this should easily net some positive outcome which can already be seen in the Ford Powerboost. I fully expect Toyota to have a far superior and more efficient system compared to FORD here.

    For the vast majority of 1/2 ton buyers a significant improvement in fuel economy under unladen conditions is far more beneficial than slightly better economy when towing. The fuel you save the 99% of your miles doing daily driver tasks more than makes up for no improvement or even a slight penalty in towing fuel economy.

    Sure, but at some point you gotta draw the line on just how much of a soul crushing androgynous shit box you’re willing to drive just to save money.

    So one thing I will say is that if Toyota retains the same fuel tank capacity for their full size 1/2 ton based SUVs like the Sequoia or the Lexus counter part, 32 gallons will be class leading.

    The GM full size SUVs have 24 gallons in the short wheel base and 28 gallons in the longer wheel base SUVs. Ford is similar to that.

    Toyota has already said they aren't trying to compete with the big three. They aren't after converting big three drivers to Toyota, they are after keeping current taco drivers that need a bigger truck and are considering the big three. When asked about fuel economy numbers a Toyota engineer confirmed that they are improved, but downplayed it by saying they just submitted numbers to the government and aren't releasing those numbers yet. He then emphasized that the goal was getting power out of that V6 and made no mention of efficiency. I would link the video, but I have watched too many and don't remember which one it was.

    I predict that the non-hybrid fuel economy numbers will be underwhelming (18-20 at best). That's still an improvement over the current gen, but not enough to win over the V8 lovers. As a result the late model gen 2.5's (like the 2021 I just bought) will either soar in value much like the FJ's did or at a minimum retain their value for a long time to come.

    I will probably still get a 2022 so hopefully I can get a good price on my 2021 when the time comes.
    I am a deep lover of tech and really want that big screen with wireless AA and the electronic power steering (I'm into self-driving systems)

    Guessing it's "city" being that Japan doesn't have much for wide open spaces.

    18mpg is decent if they're stuck in metro traffic.

    My truck doesn't approach 17 unless it's pure highway.

    If they got 18 MPG city then I would say Toyota has got one heck of an engine on their hands.

    It seems the LC300 uses an engine tuned for premium, hence the higher power numbers.

    So, mpgs might not be exactly comparable.

    Wondering if filling up with premium will unlock more power?

    Highly unlikely unless they have multiple variable fuel maps available embedded within the ECU, most OEM's don't do this. However, OV did mention the fueling tables being quite advanced on these ECU's so maybe that is the case. If so, I would suspect Toyota to fully take advantage and wouldn't make sense for them to allow variable octane fueling tables that actually increases power without marketing it. If they could say 409hp like the LC300 I'm sure they would have...

    japan have like 98-100 octane...everything that's come to America have to detune. Only Tokyo have bad traffic...

    Maybe, but Toyota will not advertise it that way or probably even admit to premium fuel making more power. They know their customers, and understand that most of them would be offended at the thought of using premium fuel.

    We have witnessed that on this site with guys who are bad at math crying loudly about how horrible it would be if the new Tundra requires premium fuel. Even though a significant increase in fuel mileage would more than make up for using premium in net operating costs vs the current truck, some people can’t accept that.

    So Toyota dumbs shit down for their customer base of tight asses in the US and we get a monkey market tune on our V35A-FTS ‘21 variant.

    Current Nissan Titan has 2 power ratings, one for 87 and a higher one for 91+.

    Even though the Titan can use either octane, I can see people bitching, being confused, or both.

    Look at the Ford F-150 EcoBoost ratings. They’re all predicated on premium grade fuel, but none of the owners know this so they put in 87 Octane.

    The #1 reason trailer towing results in poor MPG is air resistance (not weight). The bigger the trailer frontal area, the worse the mileage. The new Tundra with that huge grill and square front, appears to have worse aerodynamics than the current generation. One would think this would have been addressed first, such as wind tunnel testing. Yeah, I saw that little thing that drops down in front. Big deal, we could add that to the current Tundra. Next would have been mechanical resistance such as manual locking front hubs vs auto.
    Will be interesting to see the real results for normal driving. Trailer towing will be very close to the current gen.

    Sweers said the CD is 20% improved over the last gen. Aside from deployable air dam it looks like their is also an active sutter system behind the grille.

    Does the new Tundra appear more aerodynamic to anyone? I don't see it.

    What does appearance have to do with wind tunnel testing results?

    Are you educated or professionally employed as an aerodynamics engineer? If not your observations are speculative at best.
