Toyota Owners are being asked about new engine possibilities

No one in here said anything about emissions yet. Ya that ram has a diesel but all the emissions b.s on it is terrible. I've been around diesels at work for 5 years. That urea crap you have to add is garbage. The emissions crap is definitely not worth the extra money and with the emissions stuff you get crap fuel mileage.

 

I'd take that bet if I were more of a scoundrel. It would be akin to insider trading. I don't know what all the Tacoma will be getting with the redesign, but everything I've read is that the 1GR is not on the menu. I think we're going to see a consolidation of V6s across the board for Toyota and the 1GR is the odd man out.

 

from everything i have read and talked to people i know. THIS all the newer diesel trucks get crap MPG and about the same as full size trucks that run on gas. the older diesels got a lot better fuel milage. imho you can’t compare a diesel truck to a diesel/tdi car like the VW. the tdi vw gets great MPG while the newer diesel trucks get crappy.


and you can’t take the stuff off the trucks without voiding the warranty.


if they could get what the diesel/tdi cars could get and still do just as good hauling/towing than i think it would be better in a mid size truck. till than i’d rather just have a gas engine in one, and a diesel in the bigger trucks for really heavy towing.

 

how is the 1gr the odd man out.... the 1 gr dual vvt is in the FJ / 4 runner / Tundra.... the tacoma is the ONLY toyota vehicle with the standard single vvti 1gr....

Gonna stick by it... ill quote myself when the 2015 is announced with the dual vvti 1gr


and also +1 to urea being a BITCH.... you know what happens when you run out of urea on a new duramax... you get limited to 55mph... as soon as you shut the truck off and turn it back on with an empty urea tank... your limited to 10mph.... WHAT THE EFF... this is why the original LB7 duramax is most sought after.... no emissions crapola.

BUT if toyota could pull a nice lil diesel with 25+mpg, and similar hp as the 1gr (obviously more tq) with all the emissions stuff at a price thats no more than a 1k premium over the current taco... then they would have a winner... but thats dreamland.... direct inject gas, with forced induction would be the next best way... if not just direct injection.

and hate to be the bearer of bad news... but toyota hasnt used a turbo as stock equipment on a gas motor since the 22R-TE in 1988.

 

I already have a normally aspirated 4 that gets 28-9 mpg freeway mileage at no extra cost...

...just with a slower 0-60.

Sorry, Tooter, was comparing against current V6 mpg average.

 

My opinion... 4 engines should be offered in the Tacoma, that are (or were) in Toyotas existing inventory.

- 4cyl gas (2TR-FE current 2.7L)
- 4cyl diesel (2AD-FHV) 2.2L Turbo D/I - 174hp/295ft-lbs
- 6CYL gas (1GR-FE current 4.0L)
- 8cyl gas (2UZ-FE) 4.7L from previous 4Runner/Tundra

 

what about the 4.6 V8 thats in the newer tundras?

 

eh, who cares...I have a 2012 and I plan on keeping this baby for a long time

 

i would take the 4.6 1UR-FE ANY DAY over the 2UZ-FE.... WAY more power n tq than the ole 4.7.


But better yet.... why not the 1UR-FSE ... 4.6L dual vvti DIRECT injected 385hp / 369Ftlbs.... that would be a BEAST in the tacoma.

but a v8 tacoma aint NEVER gonna happen... thats more of a dream than a diesel one.

 

Ok. You guys are making everything way too complicated.
I'll be ok with 4.0L dual vvt-I with direct injection. 300HP and maybe 26 MPG's and keep all the reliability that Toyota in known for. No turbos for me.

Just need to be be smaller like a 1st gen, add a 6 speed manual with a granny gear and higher rearend gears. Add on a bed cover and you could get 35 mpgs pretty easy.

 

5.7 Tacoma would get 13mpg and everyone would bitch about it, just like they bitch about their 4.0 getting 16.

2003 Tundra Access Cab 2WD TRD OR 4.7l = 16-17mpg Truck was 4700 pounds and could tow 7,000lbs. http://personal.linkline.com/rlockyer/TundraGas.xls

2006 Silverado 2500 HD Duramax 6.6l, 4x4, Crew Cab, 285/75-16, 5500 lbs, could tow 12,000 on the hitch, 16,000 on a 5th wheel.
15-17mpg http://personal.linkline.com/rlockyer/2500Gas.xls

Ya... Diesel is kinda' special.

 

The 1GR that is presently in the Tacoma is built at TMMAL. There is some Japan plant that builds the 1GR for the Tundra, FJ, and 4Runner. The FJ is dead after this year. They are going to want to localize the Tundra's V6.

Enter this: http://www2.toyota.co.jp/en/news/12/05/0518.html

The 2GR-FE vehicles in the US right now are Camry, Avalon, Venza, Sienna, Highlander, RX350, and ES350. (I'm not including 2GR-FSE that is found in the IS350 and GS350). All of the 2GR-FE except the ES350 are already locally supplied by TMMWV and TMMK. So, what could they be needing 215k new 2GR units for? My guess is Tacoma. I'm also guessing that they are being very coy about the way they use the 2GR nomenclature. They are being careful to not say if it is FE or FSE (direct injection). My guess is that TMMAL will be the first US production of the 2GR-FSE and it will be in the base Tundra and the optional engine in the Tacoma.* The 1GR line at TMMAL will be scrapped, converted, or export. So, where does that leave the dual VVT 1GR? I think dead for the US market.** The 4Runner, when it sees a full redesign for 2017 model year, will be slightly repositioned to cover the gap left by the FJ and a weight loss plan to make the direct injection 2GR-FSE more palatable.

* I think we'll definitely be seeing updates to the UR V8s around this time. The 2GR-FSE making 300hp and only getting a 10hp bump to the V8 doesn't look the best on paper.
** The 1GR with dual VVT is going to be a casualty of timing, IMO. Had the economy not crashed in 08/09, I think that we would have seen the dual VVT 1GR across the board at that time. Not wanting to invest in TMMAL to update the 1GR to the newer version because of practically no competition in the midsize truck segment and them ultimately wanting to get to DI is what killed the dual VVT 1GR in the Tacoma. The revised 1GR was so different from the first 1GR that it would have taken quite the investment to switch over. The revised 1GR has a lot more in common with the 2GR than the first 1GR. Wildly different.

 

I don't see a V8 in the Tacoma's future. They already tried the 4.7 in the 4-Runner and dropped it.
I can absolutely see an update to the 4.0 with Toyota dumping the 1GR in favor of migrating the entire line to the 2GR.

 

Go buy a silverado then

Gas milage would be equivalent or better on a v8 taco . The 5.7 tundra gets identical milage as the dble cab 4.0 trucks . And the tundra a much bigger truck .

A v8 tacoma would get the same or better mileage .

The maintenance costs and the new emissions controls on the new diesels pretty much make the minimal mpg gains worthless .

 

Your wrong on sluggish performance as well. You must have owned your diesel back in the 70's and early 80's. They are a completely different breed now. Put a turbocharger on them and look out. I would agree with your first two cons though. I currently own a diesel and I own my cars for at least ten years. Current TACO is 19 years old.

 

You need to own a diesel and drive it 100K to know the difference. Yes the more modern one's have had a hit with economy but it's still about 30% better than a comparable gas engine the big difference is in the torque band it is right where you need it for a truck. My 4L falls on its face at about 2000 RPM that is just where the diesel comes to life. I tow and if the 4L drops below 2 grand it's all over and some times I have to drop 2 gears in order to keep the RPMs up it would be so nice to be able to drive 55-65 MPH with out having to shift and enjoy the far better economy. My VW diesel did 20-25 MPG better than the gas VW and I only had to fill up every 850-900 miles all 16 gallons worth.

 

I'm not a smart guy on a lot of this stuff but couldn't the engineers do something with the xmsn and the rear end and still achieve the torque req'd and mileage increase. My VW is 200,000k old and I love it.

 

I agree with those who are thinking about the advantages of the VW diesel over their standard engines and wanteing a Toyota Diesel to fill the same role. I'm not looking for more towing, or even more speed. I want a reasonable diesel that will blow the V6 mileage out of the water. I plan on keeping my new DCLB V6 for quite a while, unless they come out with a diesel to fit the bill. (I would still wait a few years to see how it works out!)
