    Highly doubt it will get 30, that lexus motor they talk about that gets 33 is in a car. Besides they're gonna gear it differently and if those numbers are correct they'd be going after best in class power specs and presumably better towing. But even if it was 20 mpg city and 23 hwy that would be a vast improvement. I'm not familiar with the Lexus motor mentioned (V6 twin turbo) ...but my first question is do they act like the Ford ecoboosts and have the mpg shit out after 50k miles?

    This article seems much more legitimate than other things I've heard about the next engine choice.

    I’m gonna assume here and say if Toyota is using the motor out of a $100k car it’s a pretty good swap for the current 5.7. I’m hoping this is true might move up to the new model if true

    The 5.7 is used in a $100k vehicle too.

    450 hp and 500 lb-ft of torque would be great, but I do not want a V6!

    "The inside source claims that Toyota’s full-size truck will use a version of the company’s 3.5-liter turbocharged V6 engine..."

    In that case, the trucks we have now will be the last great truck Toyota ever made. The two years I spent in my 2016 Tacoma with that garbage motor were utterly miserable. So much so, that I would never, ever buy another Toyota with that engine under the hood ever again. Go ahead and turbo charge it. This "one size fits all" approach Toyota is taking with putting the same engine in every vehicle is a terrible mistake, in my opinion. I really hope this article is incorrect.

    Also another thing to consider is how much faster will it wear out because of the constant high pressure due to the turbo in it? no thanks i like my 5.7 that will go for hundreds of thousands of miles :thumbsup:

    Turbo 4.6L would be better. Best of both worlds.

    Problem is CAFE standards that are basically guaranteed to become more stringent in the next 8 years, the 4.6L is already an inefficient engine. Like it or not, TT'd V6s are going to become a mainstay in 1/2 ton trucks. FWIW, I've got a 2.7L TTV6 in my crew cab F-150 from work and get 21-23 MPG on the highway at 75-80 mph which would translate to probably 25 hwy on the government ratings. I'd bet this engine will be closer to 22-23 mpg rated and get 20-21 in the real world.

    Don’t like it. Mpg is the only thing good about that. I personally feel those V-6 turbo’s are going to get tired early if they are putting in work. I mean real work i.e. towing heavy loads etc. probably creating more waste as owners get rid of those trucks early. Just my opinion obviously.

    The problem with the Tacoma’s isn’t the motor, it’s under geared from the factory. Put new gears in it and they quit hunting around constantly.

    I don't disagree. I'd say it's just going to become even more imperative to jump from a 1/2 ton to a 3/4 ton diesel if you're going to be doing much towing. That being said, a huge percentage of 1/2 ton trucks (and probably 3/4 ton for that matter) on the roads in the US will never pull a trailer or haul anywhere near payload, manufacturers know this and know they can generally get away with these TTV6s because of it.

    I will say, we run 100% F-150s in our company fleet and most are incredibly abused, we've had no engine failures that I've heard about on the TT engines so far but we also didn't with the 5.0L or 5.4L that came before.

    I've heard people mention this. In your opinion, did Toyota do this for cost reasons or was it just a mistake on their part? What would be the reason for it being under geared?

    More than likely did it to try and get the truck rated more efficiently. All of this is in response to the CAFE standards.

    I’m no engineer by any means, someone said they probably did it because of emissions but that doesn’t make much sense since they do better once they’re regeared. Honestly I’m not sure what they were thinking, but I really hope they don’t make the same mistake with the new Tundras.

    Aren't those hp/tq numbers less than the 5.7 with the supercharger?

    So those numbers aren't bad as a baseline, but if you're unsatisfied with the aftermarket options to add power on the 5.7 just wait until you've got a engine already using forced induction and a hybrid system.

    There won't be much you can do to increase performance that won't cost you $$$. And you'll have to wait a long time before the aftermarket has time to respond with options.

    This isn't necessarily true, it just depends on how "hot" the tune is from the factory (it might be pretty hot though to get those numbers), the 3.5L Ecoboost crowd saw some pretty amazing gains just from tuning that engine. That being said, the new Raptor 3.5L is a better analogy and I'm not sure what people have seen out of that or if anything at all.

    I’m sure you are correct. Just kind of a bummer I guess. I don’t mind the V-6 for daily use but it would it be nice if they still offer a V-8 as well. I would assume that the 4.6 L, while being inefficient, could be come more efficient with a turbo? If they could get that right, I think it would sell big-time. The only manufacture to offer a V8 turbo in a half ton.

    Turbos will be around in numbers until the public figures out they are a maintenance nightmare with a limited life span. Then the lots will be full of used ones. Ford is leading the way.

    Do you have some data to back that up, or are you just winging it?

    I’ve seen a fair share of Turbo charged motors with 2-470k miles on the factory unit.

    The 4.6L (and 5.7L for that matter) could probably be quite a bit more efficient if Toyota really wanted to make it so, however you eventually get to a point of diminishing returns especially if you're not going to be using it in any other vehicle unlike the 3.5L which has a more universal application and will automatically always have a fuel efficiency edge.

    The funny thing is, GM has proven for years that you can make a large displacement/high horsepower pushrod V8 that is as fuel efficient, or very nearly so, as the smaller TT V6s. DOHC V8s on the other hand (from any manufacture), while being more powerful for the same displacement, have never really managed to be fuel efficient.
