Pathetic low end torque

Only because Toyota allows the engine to rev higher (RPM). Again, Horsepower is Torque times RPM.

Torque is what makes the vehicle move. The 4.0 may not push the same peak horsepower but it has better torque down low. Therefore, it moves better from lower RPM (slow roll, stop, etc).

Both trucks are lacking in TQ/HP in my opinion. However, the 3.5 seems to spawn a LOT of complaining about lack of power down low. Why? Small displacement and low torque.

 

The first gen (220 lbs - ft) is decent for it's size, just as the 2nd (266 lbs - ft) and 3rd gens (265 lbs - ft) are for a V6, nothing monumental but they get the job done.

 

Serious question. Based on your equation, since 2nd place Gen and turd gender are roughly equivalent in torque, it's a push? I'm slow, I admit.

 

Toyota trucks started with sedan motors, that's what they used when they first came out and became famous for reliability.

You guys are buying trucks with small motors then bitch because it doesn't do the job of trucks with big motors.....

Toyota didn't fuck up, they make trucks with big motors too.

 

The turd gen does not have the same torque as the gen 2 or we would not be having this discussion.

 

Got ya. That clears it up. 266 vs. 265 = 2nd place Gen big win.

 

They have the same torque, just not the same application; 2nd gen applies more earlier in the rev range than the 3rd gen but the total values are a wash.

 

Toyota says (PDF's attached):

2015 Tacoma V6 4.0L: HP = 236 @ 5,200 RPM and 266 TQ @ 4,000 RPM.

2016 Tacoma V6 3.5L: HP = 278 @ 6,000 RPM and 265 @ 4,600 RPM



Using a conversion calculator:
The 4.0L Tacoma outputs 238.4 TQ at it's peak HP (236 @ 5,200rpm).

The 3.5L outputs 243.3 TQ at it's peak HP (278 @ 6,000 RPM).



Inversely:
The 4.0L outputs 202.6HP @ it's peak TQ (266 @ 4,000 RPM).

The 3.5L outputs 232.1HP @ it's peak TQ (278 @ 6,000 RPM).

This is just using Toyota's publish figures. Mapping both on a DYNO would give us more insight as to how each motor performs at low RPM ranges. My guess would be that the larger displacement 4.0L would have better numbers down in the 1,500-3,000 ranges for TQ. Again, keep in mind all these numbers are Toyota's best tests at the crank (not at the wheel). The entire drivetrain (transmission, gear ratios, etc) has an impact on real world performance as well.

Edit: What kills the 4.0L over all is it's relatively low RPM range as a whole. The 4.0L red lines well before the 3.5L. Even under heavy acceleration my truck wants to shift at 4,500 or so RPM. Having placed my truck on an actual DYNO I can tell you it will not surpass 5,500 RPM (redline).

 

Bingo! The 1Gr-fe produces torque/power where it is important to me. The turd gen makes power in the other end where it makes the truck go fast. Some people like that I guess.

 

Which also means where the 2nd gen feels stalled when accelerating past 65 the 3rd gen still pulls like a freight train.

 

So what I get from this is you have to step on the skinny pedal harder to get the same torque but it's there if you have the calf muscles. If I'm wrong you won't hurt my feelers.

 

That might be true but I dont go much faster than 55 when hauling loads.

 

Correct, it can be brought on sooner by running the revs out. With ECT on the skinny pedal feels even more aggressive in the low end.

 

LOL Basically.

Think of it this way. If the 4.0L outputs it's best torque numbers at 5,200 RPM and the 3.5L outputs it's best torque numbers at 6,000 RPM then there is an 800 RPM difference.

With me so far? So the 3.5L has to run 800 RPM faster in order to output 5 more torque (roughly the same let's say).

800 Rotations Per Minute = 13.3 Rotations per Second (800 / 60 = 13.3333).

So, the 3.5L has to rotate 13.3 times MORE per second than the 4.0L does to create the same amount of torque.

If you want to pull a really heavy object on a sled you find the biggest muscled guy around and have him do it.

But if you want to go fast you find a small, athletic, agile guy to pull your empty sled.

 

I'm not hauling loads everyday, more empty bed daily on the highway and plenty of people complain about CC when running at 70+ here.

My 1st gen felt like a handful over 65, screaming to keep up with traffic.

 

Once you rev it out... you're no longer in the low end. You are just reving high going slow.

 

So why my 1st Gen felt more peppy from stop while my turd Gen feels way more powerful going around a semi from 60. Same with 2nd place Gen. Works for me.

 

Yeah, Tundra being the big muscled guy, that's why they advertise them for towing and load capacity and towing your big heavy sled. What loads do you see the Tacoma's advertised as hauling? Not much, maybe mountain bikes or towing a couple of jet skies.

Again, buy the right truck for the right application.

 

Have you driven one yet? You might be surprised how quickly it comes on when configured for it.

 

hp is a function of torque and engine speed. The above equation is missing a big piece.

HP = (TQ*rpm)/5252.

This is why every dynograph has the torque and hp curves crossing at 5252rpm... there has to be a constant.

As for beating this dead horse.... I think it's been beaten so much for so long, at this point you are just pounding sand
