2021 Really the last year of the V8 for the Tundra?

    More gears theoretically would allow for smaller transitions between gear changes and ideally keep it in the most fuel efficient loading in every gear. Additional gears could also add additional OD gears which is where the highway fuel economy really comes out. Tundra already has a rather high or tall 6th at .58 or .59. They could change it some, but yeah it would be more about evening the gears above 1:1 for better city fuel economy. It would be marginal but 1-3mpg isnt unreasonable. Dont think people would complain if the 2022 came out with a V8 that had an 8 speed and managed 15/20, thats a reasonable target and would put it right up to the actual observed economy of the F150s and non diesel Rams.

    Believe it or not but the Land Cruiser outweighs the Tundra.

    Toyota could also incorporate aluminum panels on the hood, fenders and bedsides and save a 100 lbs. Hopefully if they go that route the dont do so on the doors.

    I believe the f150 saved 750 pounds going with aluminum

    LC's have never been known for their high MPGs, they are heavy and thirsty.

    I just dont want a aluminum bed or doors. The Jeeps have aluminum doors and look terrible, aluminum is not great for the bed box for obvious reasons. The rest of the areas are fine with me, aluminum doesnt rust either, bonus there.

    Carbon fiber bed will cut weight while increasing strength, right? The new Sierra offers this option.

    Cost is the major concern there, I don’t know about them specifically but they likely used a CFRP or something similar to what the Tacoma’s have but with CF. Honestly I would prefer a composite bed like the Taco. Its lighter and strong enough. Stays warmer than metal. But is very slick, bed mats fix that though.

    Meh, I owned two F150's (diesel and 3.5 screw). The 3.5 got poor gas mileage if you drove it like you wanted to drive it; or when towing. Comparable to the Tundra actually.

    The numbers they quote have to be calculated putting around without using boost.

    Auto Start/Stop is actually the worst feature in the history of the automobiles. I looked it up. It's true.

    I remember hearing about them testing for fuel economy and testing them at lower rpms to keep them from spooling as much. All I know is fuelly doesn’t make a great case for the Ecoboosts. It’s better than nothing I guess but not worth any up charge.

    When I bought mine, it was actually an upcharge to get the 5.0 Coyote over the 3.5 Ecoboost. If I did Ford over again, which I won't, I would go with the 5.0.

    So did I, and after watching the video I think it depends on the situation.

    I've also aways been curious towards the effects of putting the transmission in neutral in traffic / stop lights would have on the transmission itsef.

    And I didn't realize the engine would be smart enough to shut down the fuel injectors under engine braking. Figured just like idling, they'd be pumping something just to keep the fire lit, and more rpm would = more fuel. Apparently not.

    You would think neutral at stop would gain a slight increase in efficiency just from reducing the load on the engine, but I've already been wrong once today, so I don't know. :notsure:

    Stop
    Yes....every time you get in it has to be turned off.

    Also, another thing I do not care for is the fact that all of the “tech” to make it work is still on the truck. I like things simple. I would even prefer a key in my Limited, but they did not give me the choice.

    I would like to see them add D4S tech to the v8 engine. They could even use and retune the 5.0L engine in the IS-F. This would allow more power and less displacement. The Ford 5.0 is 395/400 on power.

    I owned an ecoboost, and when towing, you are in boost and the gas mileage is very similar to a V8 with no turbos.

    I agree with the auto start/stop. I disable it every time I have to drive my wife’s Highlander. Engine stop, no a/c, no thanks. It may cost me money to repair the starter later on. It is one of the worst feature in automobile next to the cylinder deactivation.

    Absolutely! Cylinder deactivation is running second place on my books. For those who have an interest in how their vehicles are running...that surge that occurs during the deactivate cycle is disconcerting.

    In my opinion, it really depends on where you drive. I have to stop at a lot of long red lights on my commute so I think it would save me fuel (in the summer when I'm not running the heater full blast) but if you mostly have yield or stop signs or stop and go traffic, it probably isn't great. If they do add it, they need to include a disable button like GM did.

    As long as their weight reduction doesn't lead to leaks like everyone else's did...

    That's been their philosophy for years. My wife's 2012 Corolla seemingly wants to be in 4th gear at any speed over 10 mph.

    One thing I find pretty funny is that everyone seems to want a diesel - and what do all of those have now - turbos. Yet try to put a turbo on a gas engine and it's the end of the world. With proper heat management and lubrication the reliability of the turbo isn't going to be the limiting factor in most vehicles.

    And as far as auto start/stop it bugs me because you have to change your driving style. You have to allow for some creeping before accelerating from a stop - Tundra you can go from brake straight to throttle, but with the auto start/stop you have to delay to let the engine get settled.

    It’s horrible. My work vehicle is a 2020 Equinox with the start stop and there is a lag before it starts up. Plus, there is no way to shut it off.

    I hate it because I want the a/c to remain on when I stop, both winter and summer. I like conditioned air. Also, I’m willing to take a 1 or less MPG hit by deleting auto stop; It won’t break my bank. May even cost me more in repairs starting/stopping engine so many times.

    I may consider auto start/stop if there was an electric ac compressor that can run off of battery when engine is stopped. I’m not sure if that is even possible right now.

    Should have specified the GM half-tons. Manufacturers seem to know truck guys have different requirements than your average commuter.

    The Ram eTorque system actually handles auto stop/start properly, IMO. I bet you see future vehicles using this kind of hybrid assist for the stop/start.

    Makes me think of the people who obsessively shift their manuals into neutral at every stop light or stop sign
