2022 Tundra

It's supposed to be the same engine that the Lexus LS500 has (I think)

 

Has anyone heard about reliably issues with the LS500 engine? Obviously people aren’t using their LS500 for towing so they probably aren’t getting much abuse. Although the Ecoboost issues don’t appear to be only linked to those who tow/haul often.

 

Won't happen. It's bad enough the 5.7 is a pig now guzzling fuel and asking for more. So then you want a bigger engine that's just going to be worse. Input 32k miles on my 2020 the one year I owned it and I'm already doubling my fuel mileage and only had the GMC for a week. Even towing a trailer I'll almost double my mileage

Better than my wife's 2021 Highlander hybrid AWD platinum

 

Won't be anything special with a TT V6. The pint of me getting a diesel is two fold. I get 460ft lbs of torque starting at 1500 rpms and almost all of it before 1500 rpms and the torque stays on all the way to 3000 rpms and fuel economy. Yes the V6bwill get better fuel mileage but in order to get the max power, you have to get into much higher rpms. I noticed when I pull my trailer going up inclines, it tends to utilize that torque and pull rather than having to downshift a lot to do it.

 

Please Toyota, don't make it so ugly it looks like a catfish.

 

Agree 100%. Problem to me is cost. There really is no improvement in building a "more reliable" ecoboost. The fuel costs associated with premium fuel and the amount that I tow a heavy (for a 1/2 ton) travel trailer, boat and sea doos will offset any improvements to the point that I won't be tempted to buy one. The increased purchase price will take too long to recoup and likely never will.

Now, the AT4 with 3.0 Diesel... yeah there will be some increased maintenance and I know about dropping the transmission at 150k miles. But it has fantastic low end torque, great appearance, is getting 30 mpg highway, and most are getting around 15-17mpg when towing 7,0000 (+) pounds with the thing. It has the rear camera mirror which is just as cool as the Tundras back window, and a legit safety feature. It has about 350-400lbs more available payload when you consider adding running boards to a current Tundra, and while not as offroad capable as the PRO, the AT4 is a fantastic compromise.

From what I have read it functions like crap if you put anything but high end premium in it. Now you might say, "Well there is not that much difference between the price of diesel and premium fuel". But diesel is not as market sensitive as gasoline. It's price tends to stay relatively constant. There have been changes in" the forces that be" that cause me to think the price of gasoline will jump significantly over the next two years.

 

I totally agree with this.
I would hate to get rid of the V8, but ultimately most of us will eventually start liking whatever is offered and before you know it there will be lots of drooling going on.

 

With a face like that it could make some extra fuel money at the truck stop

 

That 1500 GMC AT4 diesel does appear to be a solid truck. I took a serious look at that and the 6.2 version. I ordered up a GMC 2500 AT4 gasser a couple weeks ago, wanted to have more than enough capability for my travel trailer.

 

It's the ugly kid you didn't want to have but have to take care of LOL. Only a face a mother could love.

 

Have you been through a regen cycle yet?

I like the baby dirtymax. Some of my friends only get 20mpg depending on how many regens per tank it ends up doing. But they are 4wd and tow. The diesel forum users seem to get near 30 like you do.

 

Agreed. I'm not at all opposed to TTs, but in this case it's because it's Toyota. We know that while every automaker tweaks out on something, Toyota has a reputation for reliability, and I seriously doubt they're going to cheap out on a Toyota 'Ecoboost' and allow it to result in the reliability issues the 3.5L on the F150's had early on.

With that said, even were I made of money, I'd STILL wait until at LEAST about 2024-2025 to allow them to work any issues out.

 

All these nervous posts about no v8s. I hope my miled out v8 tundra goes up ten fold in value. Trader in on a turba v6 for power and mileage. I’m in. It’s 2021. We’re all on the forum high fiving each other over 13mpg haha. Change is inevitable.

 

It blows my mind how much R&D companies are putting into new technology making a gas engine pretty much run like a diesel to up its thermal efficiency. Like Mazdas HCCI and SPCCI engine. If we would just get past the whole stereotypical "dirty" diesel thing and just spend time refining the diesel engine we could figure out the emission problem and have clean, heavy duty great milage engines. Ducted fuel injection systems have been touted as eliminating soot, and just overall better emissions, and easy to incorporate.

Ditch the gas engine, go to diesel and then start incorporating hybrids/electric powertrains. There already more efficient by design. All your power at low rpm, way better towing, better milage. Who doesn't want that in a pickup.

 

I love how so many are scared of turbos because of the Ford EB's. Yet every diesel has a turbo, most small cars and SUV's have turbos, it's not like they're new tech. For the few that tow all the time and fuel mileage matters they should be in a diesel. But for most that do the occasional towing having consistent mileage doesn't make much sense - why not go for 30 MPG unloaded and 15 loaded over 15 unloaded/loaded? As long as they don't mess up the gearing like Ford does and doing 65 mph stays in the good fuel mileage range I think it would be a winner.

 

Unless the diesel is 2 times bigger then the gas motor i dont see that happening fuel milage wise. You should be able to do better on both fronts....I would think. As said above that 3.0l duramax is getting 30mpg on the highway and getting 16-17 towing.....but we continue to try to throw every bit of technology into a gas engine to get in that range. And it only will if your very light on the pedal....

Although it is a small car....I have a 2002 jetta 1.9l diesel manual trans, and you can run the absolute piss out of the thing and it still gets 40 mpg.

 

Couldn’t have said it better!! My wife’s 4 banger hybrid RAV4 is actually pretty quick! Kinda looking forward to a bad ass TTV6 hybrid that can get 30 MPG!

 

True, it happens to any change. I remember people say they will keep their "old school" cellphones and never going to them unreliable, easy to break smart phones. Which before that, people with landlines say, I'm sticking with "old school" tried and true landlines, not dealing with no signal. Even, I've heard some were thinking to stick with mailing letters rather than use a telephone.

Come on now, who of you call themselves "old school" are hand washing their clothes?

 

Yeah it's supposed to be a good motor, most inline sixes are. Nice truck also, I hope it does well for you. What is the difference in price per gallon between gas and fuel in your area?

 

Haha. No handwashing the clothes, but ask any good appliance repair (wo)man if you should get an "old school" washing machine with an agitator, or one of those modern eco, water saving ones with no agitator. I bet you can guess whether mine has an old school agitator.

 

It's a good motor. It's a Lexus motor so it is held to even higher standards than a typical Toyota motor, by Toyota.

Also in truck form it will be tuned and configured for more low end torque, so in effect it should be even more reliable than the car version of the motor

 

If I didn't tow much, I'd want the same. Not expecting Toyota to make a truck for people like me, I'll just be disappointed if they don't.

 

Problem is the emissions. Stand behind a diesel exhaust for 5 minutes and tell me how you feel. Are they as bad as many are trying to make them out to be - no. But diesel engines certainly aren't good - there's a reason hybrids have taken over from diesels for the eco option on most vehicles. Ford and likely Toyota bringing hybrid tech big time into the truck market (GM half assed it and didn't give it enough power) could spell the end of diesels - if the electric motors can do enough. Fleets are already leaving diesels unless they need them so it's only a matter of time before they're gone.

 

Yes the EPA ruined the diesel in this country. If we had the emissions laws Europe does we would all be driving diesels right now. And toyota would be producing diesels here in the USA

 

Agreed. Though no one likes to mention the diesel engine is already more efficient, so could the emissions produced be a wash compared to gas? I dont know. I know NOx is a big concern because the the high temperature of exhaust gasses.I think if we spent as much time into figuring out the emission problem as we have into gasoline engine tech it would be significantly better by now. Though like you said with hybrid and electrics it probably is to late. Electric cars have a real energy density problem as of now...

Here is an article of ducted fuel injection, it very simple and helps reduce emissions. Also can't throw out the possible use of biodiesel, which yes has its own problems.

 

I've been told the primary difference is in the quality of the fuel. Europe actually has clean diesel; their engines can't run the stuff we produce over here.

 

I honestly don't know because it's hard to tell when it's performing one. When I had my 2013 VW TDI it was easy to tell because the idle would increase when I was sitting still but haven't noticed it yet. I only have 308 miles on the clock.

 

I've never heard of this. Always was under the impression all the fuels are the same

 

Someone telling it like it is. What do you think about evertyone saying to wait a year before buying one?

 

It will, Fred & Barney
