New Engine

Hey Gincoma, I'm still waiting for information regarding the 2016 3.5L V6 operating on both Otto and Atkinson cycle from Toyota...

I hope your right however all we have heard/read from Toyota is Atkinson.

Please prove me wrong.

 

Huh. I swore the press release video said both.... But I reviewed a transcript and it only said Atkinson. Huh. Are we merely internet derping? Very curious... Hope someone can find a statement.

That said, based on the avail VVT-iW tech available, it isn't out of the realm of possibility.

This isn't the Tacoma but it's the same technology, just FYI

 

Thank you, but I'm well aware of this technology. It's relatively new to Toyota/Lexus. It's found on the Lexus 2.0L turbo.

I hope it's on the 3.5L V6 in the'16 Tacoma however I would think Toyota would have stated VVT-iW to promote their technology if it was going to have it. They went out of their way to state Atkinson cycle, more power, more hp. No mention of torque, nor were any of the auto writers smart enough to ask.

My point to Gincoma is that people keep saying the '16 tacoma WILL operate on the Akinson and Otto cycle. When I ask for proof from people from Toyota backing up their claims, I hear nothing....because they have not stated that.

 

You're right. There is no "Official" statement about the new engine. It's very likely though that this new tech will make it into the Tacoma. The reason we haven't heard anything yet is because they are still tuning or they don't want to release too much info for competitive reasons. Lexus tech has always trickled down into toyota Vehicles, there's no reason to think this time it would be any different.

 

The iron block 4.7 won't reappear. Smooth, smooth engine though. Had a supercharger available also, but in the later versions the weaker piston rods couldn't handle the boost.

Maybe sometime in the future the 4.6l V8 will be available for the Tacoma. I'd be happy with anything that produces 320+ torque in a midsize for towing and isn't a diesel. A turbo wouldn't bother me at all. Toyota seems reluctant to put a turbo onto their gas engines, but they have turbos on the diesels. Why not turbo gas engines?

 

I know it won't happen but I keep wishing that toyota will surprise us all and announce a v8 option when they release the trd sport. Like the other guy said toyota hardly ever over powers anything but a v8 in the tacoma would be a perfect truck in my opinion. I have a 02 4Runner with the 3.4. It's an amazing truck with a great engine but it's so damn slow. A v8 would make it perfect. I just hope that the 3.5 delivers because I'll be in the truck market in a couple years and always loved the tacomas

 

My mom has an 05 v8 4Runner and it blows my v6 out of the water, not only is the engine smoother but the sealed 5 speed is way better. It's my moms third 4Runner and by far her favorite. They are looking at getting a new one but she's very hesitant because she doesn't want to loss the v8. I agree with you, I would love a 4.6l option way more than a diesel option (yes I said it). It would fit the Tacoma way better then the Tundra, but at this point I think it's a pipe dream. I think we are 3-5 years away from seeing a turbo in a toyota model. They just released the first turbo Lexus and it will take a few years for that power plant to come down into toyota. They seem to have spent much more time in R&D on the turbo tech then the domestic companies have.

 

Right there with you, wouldn't buy a diesel if it had a $10k lower price tag (which it obviously doesn't), and would happily pay a lot more for a v8.

 

^^^ Truth

Google 2008+ WRX STI engine failures if anyone has any doubt that lean tunes from the factory are a bad idea.

 

moms 07 4 runner limited 2wd is a v6... lined up next to my buddies similar year 4th gen 4 runner v8 limited 5speed 2wd.... and proceeded to get on it.

the v6 slowly walked away from the v8 till about 80mph.

that 4.7L is meh... doesnt make a whole lotta power. The 4.6L UR would be nice but aint gonna happen and mileage would be meh as well.

 

I don't drag race my truck, so therefore I'm no concerned with 0-60. I drive about 40k a year in oil field traffic mainly on two lane highway so I'm much more concerned with quiet, smooth and 60-100 acceleration. I'm guessing if you took the same 4runners and and started at 60 and floored it, it wouldn't be close.

 

One thing for sure with new engine no more changing oil mid winter in the snow under 5 minutes with out spilling drop of engine oil.

Oil filter on the top of engine .... > Best freakign idea ever, kudos to Toyota eng that came out with this.

 

aint that the truth!!! the design of that was genius!

Pull lil cap pop a cup underneath, spin off oil filter, wipe up, spin new one on. Place cap back on. Boom done.

 

i actually took a 1 liter coke bottle and drilled a hole in the top of it.. then inserted a rubber fuel line through it and attached the other end to where you take the rubber cap off by the filter.. that way when i twist the filter off the oil drains into the bottle.. then i use brake cleaner and spray where the oil drains and it also flows down into the bottle.. just drill the hole in the cap slightly smaller then the fuel line so it fits tight and dont slide to easily.. when finished just remove the cap from the bottle and pour into your dirty oil container...

 

It really was a wonderful little design. I love changing the oil just because it's so freaking easy.

 

There is a good chance torque will be same or slightly lower while MPG and HP increase. However, the 3rd gen should be lighter and towing should be increased too.
I have heard Toyota spokespeople see MPG, HP and towing will indeed increase but none of them have mentioned torque. If there were a big torque increase they would be bragging about it already.

 

Well, look at the specs for the dual VVT-i 4.0l vs the 4.7l single VVT-i.

254HP/270 torque vs. 271HP/315 torque for the 4.7l.

The 4.7l made more HP and torque. Being an iron block the 4.7l probably 150 lbs heavier. The 4.7l has nice fuel mileage also, I'm getting maybe one mpg less in a '05 Tundra 4WD Access Cab 4.7l compared to the 2012 Tacoma 4WD Access Cab 4.0l. And the Tundra is 500 lbs more curb weight with the iron block and the steel bed.

Put that nice dual VVT-i 4.6l into the lighweight composite bed Tacoma and it would get good mileage simply because you wouldn't have to put your foot into it as much to get up to speed. The same with the 4.7l in the Tundra, I don't have to put my right foot into as much to get the truck up to speed. Plus, the V8 sounds soooooo much better.

Unfortunately, you're probably right no V8 will be put into the Tacoma because the CAFE standards have that complicated footprint vs. dispacement deal that penalizes manufacturers if they put too much engine displacement into a smaller footprint vehicle.

 

Why is this stupid thread still active? Please just let it go!

 

A torque increase is what I would like to see. HP is attention grabbing, but torque is more important for a truck. I was looking at Edmunds longterm test of the new Colorado Z71, after 7500 miles or so they're getting only 17.5 mpg overall with that supposedly butt-kicking 305hp/269 torque V6 that was supposed to get 20 mpg overall.

They threw a motorcycle into the bed once, towed with it twice for about 600 miles, and voila, 17.5 mpg combined. Low torque motors in a truck with their heavy curb weights it takes a lot of right foot to actually keep them moving in the real world.
