Why did they not use the 4.0 Dual VVT-i V6?

I find it interesting Toyota says this 3.5 is a brand new engine. The short block and valve train I suspect is a complete carryover. They basically changed the heads for direct injection, added liquid cooled exhaust manifold, better designed vvt plumbing with more advanced valve timing. The new Lexus RX350 has the identical engine.

 

What does the Hilux have to do with CAFE ratings in The United States? Not a damn thing. CAFE plays a HUGE roll in all manufacture's decisions these days. In order for manufactures to sell vehicles that get 15 MPG...they have to sell many more vehicles that get 30+ in order to average out their fleet's MPG. Quickly disappearing are all the loop-holes that trucks used to be able to jump through to get around efficiency. Most trucks don't even come in a standard cab anymore BECAUSE of CAFE. The shorter the wheelbase the better the mileage has to be.....hence the death of the RC pickup in most line ups. Toyota gets around it on the Tundra by putting a very long bed on the RC so they can produce it on the same wheel-base as the AC and DC models.

It doesn't matter what the actual MPG most people may get in the new 2GR Taco. If the 2GR can eek out a 2-3 MPG more than the 1GR did in overall mileage based on EPA testing...then in today's environment...that's worth it to Toyota...especially with a volume leader like the Tacoma. This most definitely has to do with with CAFE...every bit as much as it does cost savings.

 

And speed limits are speed LIMITS, not speed directives. Sometimes it's best to pace traffic, many times not. And help me with this one: Even when the speed limit is 70, 75, 80.... there's still that group exceeding it by 5, 10, 20mph. Next thing you're doing 80, BUT IT'S MUCH SAFER CUZ YOU WON'T GET RUN OVER. (Woopsie, there I go thinking again. My bad.)
Let 'er rip.

 

Huh....
2016 Hilux gets better mileage than 2016 Tacoma... it gets that because it has the same transmission and crap load of low end torque. So when 2gr needs to rev up 1gr simply continues on higher gear (more fuel efficient)
If Toyota cared about CAFE they would have gotten 1GR with 6 speed like in Hilux.

 

Again....it only matters what the EPA says about it. Not what some guy that likes to argue about everything on the internet says. There was a "cost up" for Toyota to throw some new tech at the Taco's version of 2GR and the new tranny and to marry it with the Taco's chassis. If it were only about cost and nothing else....Toyota would've left the 1GR right where it was at. CAFE is driving this. And down the road a few years, if having a common block for most of their V6 engines saves them some coin, then that's a byproduct of it all.

You're pissing in the wind trying to compare different markets.

 

Never said they were perfect lol. Haven't heard of the perfect unfallable motor yet. We have to admit better than the majority for mass production standards.

 

Oh Really ? Its you who have no clue.
If you think Toyota was going for CAFE then you gotta explain why they dropped 1GR from Tundra ?
Its simple 1GR was dropped because having another engine line was too expensive, not because 2gr is better engine. Its cheaper for Toyota and that is it. You can acknowlege that or try to spin up whatever BS comes in your way.
They dropped 1GR from Tundra and from Tacoma. But more Toyota global trucks got 1GR produced in Japan.

 

Outside of town the interstates are 80, close it is 65....sure people speed...but there are a lot of cops here...I see multiple people pulled over on my daily commute of 65, I got enough speeding tickets in my younger years...hell even had my license suspended for drag racing when I was 16. Now, I just set the cruise at the speed limit...or slightly below. 62-63 seems about right, without having to pass cars so I don't have to touch the cruise. Going slow and taking a bit longer to get there...sure beats a day wasted in traffic school.

Guys that need to be "throw on back in the seat" at the slight press of the gas pedal are kinda funny.

The new engine has plenty of power for running around...I'll never use all of it. Even my underpowered 1st gen, I rarely use it's full potential.

 

That was a Joe Dirt referenced joke. C'mon man...

 

Sorry I must have missed Joe Dirt.

 

For all you millennials:

 

Thanks but I'm 53, boomer not millennial.

 

Because the 1GR is being phased out across N. America. Made since for them to drop the the 1GR at a model change in the Tundra...which is typical of something Toyota does with an engine change. The 4.6L V8 can get nearly the same MPG according to EPA ratings as the 4.0L (if not in the real world)...and with the 4.0L being phased out they still have to have a "price leader" engine. What other engine do they have for this market/application? The 4.6L I-Force...that's it.

Once again.....you're comparing different markets. Manufacturers cater to the markets they are in. Putting 1GR's in vehicles overseas has ABSOULETY NOTHING to so with what happens over here. They're bound by the mandates of each country. In The USA...that means already very stringent efficiency and emissions standards that are only going to get tighter over the next few years. As I mentioned....having a common block for most applications, that might save money over the years, is a byproduct of that.....not a driving force.

 

You bringing up 4.6 which is paired to six speed that makes no sense. Compare 4.0 to 4.7 .
If you want to compare 4.6 than you need to compare to 4.0 with six speed so thats new Hilux. Which one is more efficient?
BTW Your arguments are getting convoluted, you arguing that small MPG improvement of 4.0 (smaller displacement) is not enough for Tundra but meager 1 MPG difference between 4.0 and 3.5 is all that Toyota needed to improve CAFE?
You are making no sense.
Toyota is getting cheap, they want to reduce number of engines, that's all there is too it. Nothing wrong with it, except selling that as the blessing for buyers is stupid.

I am not comparing different markets, my point is the same engine that sits in 4runner paired to the same transmission that seats in 2016 Tacoma gets better MPG based on testing than 2016 Tacoma....
And that is a fact...

 

I haven't clue what your talking about. You can be hard to follow. The 4.6 I-Force is what's currently in the Tundra as the base engine, BECAUSE TOYOTA IS PHASING OUT THE 1GR IN NORTH AMERICA. Why would I bring up the 4.7L....a defunct engine that's not been used for awhile now. In a vehicle as heavy as the Tundra, a small V8 will probably get about the same EPA rating as a big 6. So with the 1GR going away...it was the only choice Toyota had as the price-leader engine.

The 1GR in the current 4Runner is breathing it's last breath. It will be replaced at some point in the not so distant future.

 

BOOM!

 

Thats the point, if you comparing with 4.6 than you need to go with Dual VVTi 1GR and 6 speed so you comparing new setups and new engines. 4.0 Dual VVti with 6 speed is Combined 19.6 MPG in 4x4 Hilux. So which V8 gets that in Tundra ?
And if Toyota was intersted only in CAFE as many people keep saying and not being just cheap SOB why would they not go with more efficient setup on Tundra.
Its hard to follow because you comparing apples to oranges (new 4.6 with 6 speed to old 4.0 with 5 speed) while claiming that CAFE is the reason for going to 3.5 with speed (lower displacement with 6 speed transmission)
So its either CAFE standards or not. if its CAFE standards than dual VVTi 4.0 with speed makes way better MPG for Tundra than 4.6.
just like 3.5 with 6 speed makes better mileage than 4.0.
I dont see why defending corporation that is simply cheap. You trying to make excuse where there is none. People are blaming CAFE when it suites them. And in this case CAFE has nothing to do with it. Toyota simply chosen to go cheap (I bet those crappy heads for 2gr-fks engine are produced in China factory in Tianjin same factory making heads for 7gr )

 

You're relentless. I'm out. Not because I think you're right....but because you've worn my resistance down. You win.
