New Engine

Correct me if I'm wrong, but wouldn't the 4.0 have more potential than the 3.5? More torque, larger displacement? Sounds like the 3.5 has better technology crammed into it, but isn't that something we could do with our 4.0's?

 

Yeah but that would make for better truck, and no longer make 1Gr as bulletproof Land Cruiser option.
1gr is used for Land Cruisers and Toyota takes quality over efficiency on this one. So they won't do anything they don't think it would make their Land Cruiser fleet be on par with Yugo.

 

Yes, but less mpg to go with it. It's all about making the amount of power needed for the customer while still getting the best mpg possible.

 

I don't think that is the correct engine,especially the output specifications, my guess is the output will be less. Theabove engine, 2GR-FSE is an Otto cycle engine. We know the 3.5 liter V6 in theTacoma will have D-4S and is an Atkinson cycle engine. One application of 3.5LV6 with D-4S and Atkinson cycle is the Lexus GS450h, 2GR-FXE.

286hp @ 6,000 rpm
254 lb-ft. @ 4,600 rpm
91 Octane fuel

More hp and less torque than the current 4.0 liter V6 in the Tacoma however.

We have heard more power and more hp from Toyota regarding the 3.5 liter V6 inthe ’16 Tacoma, which the above specifications meet. I have yet to read in aToyota press release or hear from a Toyota representative that it will havemore torque. I have heard nothing specific regarding torque from Toyota, whichis concerning. I certainly hope it has more torque however if it’s strictly anAtkinson cycle engine I don't see how they will accomplish that. My only hope is that this engine will haveVVT-iW (W meaning wide) that allows for the engine to operate in both Atkinsonand Otto cycle depending on demand.

Or Toyota feels that the torque output to the wheels will be the same or betterthan the current 4.0 liter V6 with updated gearing in the 2016 (new 6 sp auto,new transfer case and new rear differential).
-------------------------------------
Another indicator that the ’16 Tacomaengine is not in the Lexus ES or GS:

The Lexus IS350 that utilizes the 3.5L V6 2GR-FSE engine, has a redline of 6,400rpm.The gauge pictures of the 2016 Tacoma show a redline of 6,000rpm, the same asthe Lexus GS450h, 3.5L, Atkinson, D-4S 2GR-FXE engine...

 

And you have to run more expensive 91 octane fuel all the time.
Its probably why Toyota is not giving any info.
When they show case current 2Gen they had number ready with it. MPG , horsepower and they bragged and bragged about all that torque and power.
Current silence is foretelling .

 

yeah no kididng. sootiest [yet epa legal] exhaust I ever owned

 

Correct me if I'm wrong here but I remember the X-runner guys have swapped the T56 Tremec 6-spd into their trucks with a adapter of course.

 

UGH....

AGAIN....

The "NEW MOTOR" is NOT IN ANY CURRENT LEXUS VEHICLE.

ITS NOT the 2GR-FXE as it only does atkinson cycle....

ITS NOT the 2GR-FSE as it only does otto cycle....

ITS LIKELY a combination of both technologies and tuned for a truck application and could possibly be labeled 2GR-XXX where XXX are its sub class.

Toyota would not put a motor with LESS torque or LESS hp then its current offering in a new gen of truck.

Plain and simple... thats all we know!!! so stop assuming or spreading falsities

 

Where's your source of information that it's not this engine?

Toyota has stated "all-new" in the past regarding different model and just inserted a engine from a different model. It is "all-new" to the Tacoma, just marketing schemes...

I provided what I believe will be the engine in the '16 Tacoma based on what has been released from Toyota. 3.5L V6 with D-4S and Atkinson cycle. This exact specifications exists in one Lexus vehicle. Yes it could be tuned to perform better for a truck. However if it is strictly and Atkinson cycle I highly doubt it could get more torque than an Otto cycle engine. If it were to have VVT-iW which would allow both Atkinson and Otto cycle I believe they would have stated that.

As I mentioned Toyota has printed and said that the engine will be more powerful, they have said more horsepower. I have yet to hear more torque, that seems to be a very rehearsed response. And unfortunately the auto writers that interviewed Toyota's Mike Sweers never asked a direction question regarding torque.

I also stated that perhaps the torque delivered to the wheels will be very comparable or slightly more with the new transmission, transfer case and differential. This would make up for the loss of engine torque output, which is fine with me.

 

I think we're getting a little ahead of ourselves here. The only thing we know for sure is the 2GR designation. The FXE motor runs solely on the Atkinson cycle and is used primarily for a hybrid setup, which would make it an unlikely candidate for the Tacoma as a stand alone motor.

 

LIKE stated its likely a 2GR-XXX ... there is currently NO 2GR that does both atkinson and otto cycle with D4-S direct injection like the one found in the 3rd gen.

Given the closest relative the 2GR-FSE making 305HP and 278ftlbs with some tweaks to cam profiles and timing you could drop hp by 15-20 and keep torque around 280ftlbs but have both hp and torque over a broader range quite easily.

Like stated, i HIGHLY doubt toyota would put a new motor in their new truck that does not have more hp AND tq compared to the current model.

 

Where is your source of information that the engine will operate on both the Atkinson and Otto cycle?

 

That's what I thought. Try explaining that to nd4spdbh...

It would be nice if it operated on both Otto and Atkinson, however I have yet to hear that it will. Atkinson only, which is what leaves me to believe it will have have less torque.

 

It's the same technology Lexus is using in the new RC-F. It uses a new variable valve timing system to "Simulate" the Atkinson cycle at low loads. When more power is needed, it switches to the regular Otto cycle. It's toyotas version of cylinder deactivation.

 

Toyota. This has been beat to death in three other threads. Y'all are late to the picnic - no sandwiches left for you.

 

Really? I always thought the 4.7L out of a 1st Gen Tundra would be a perfect match for a 2nd Gen Tacoma. That would be my engine of choice to swap in. The one I had in my '05 Tundra DC was an animal...

 

Did you just come out of the cave? The new engine runs both...read a little more.

 

My 05 Tundra DC had the garbage i-force V8 and towed 10k pounds relatively easily, had no issue with minimal maintenance, and walked Tacoma's off the line at stop lights. The UZ series V8 has been around for a long time and never really had any serious issues, possibly a leaky water pump...... Anybody who thinks that it's anything remotely close to "garbage" is very ill-informed.


The wiseguys who decided to put this junk motor into the cream of the crop Toyota and Lexus' should be fired immediately.

 

I loved my 2005 V8 4Runner.

Craploads of power, great pairing for the 5 speed tranny, quiet and by far the smoothest engine I've driven, better MPG than my 6speed Tacoma.

Stock 4runners have run 15.0 seconds in the 1/4 mile. One of the few great engines pairings Toyota ever made. Rarely does Toyota put an overpowered engine in a vehicle, but this and the v6 RAV4 were awesome to drive.

 

Please point me to some information from Toyota regarding the '16 Tacoma running on both Otto & Atkinson cycle, I'm very interested.
