When are we going to get HP numbers on the Gen 3...

The torque shouldn't drop on the tacoma it should go up. Considering in 05 the 4.0 was rated at 280 lb ft of torque.

 

the 4Runner has a more powerful motor then the Tacoma and is only rated at 5000 pounds. There is more to factor in then just hp and torque. And Toyota tends to lean on the conservative side whereas gm and Ford are known to inflate numbers for marketing reasons.

 

Isn't a 4Runner heavier than a Tacoma?

 

By about 500 pounds and it has a higher max payload. Point is that HP isn't the main factor in the tow rating as some people tend to think it is.

 

I'm not so sure Toyota is always so conservative with their towing #s. A 2006 Tacoma DCLB V6 4x4 is only a few hundred pounds below a 2006 Tundra DC 4x4 tow rating. 6500 vs 6750 I believe. And then there's the V8 4runners that were rated at 7k plus. I believe they topped out at 7300. The new 4runner is where it should be and if anything is inflated its the 2nd gens #s because my 2006 DCSB Tacoma couldn't hold my 05 Tundras jock when it came to towing.

 

Every auto manufacturer is supposed to be following a set of automotive standards now when it comes to rating how much their vehicles can tow:

Nissan is the only company that is not complying. I'm guessing they will overestimate the Titan XD towing and then join the standard so that there Diesel can have over inflated towing numbers.

Anyways the point is that companies won't be adjusting there tow ratings every year without changing anything on the truck just to keep up with the pack. Now they have to actually follow this standardized way of determining the tow rating.

 

Plus, does ANYONE here really understand power figures and what they mean? The only reason the current 4.0 doesn't make a lot of HP is because the redline is SOOOOOO low. HP is a simple mathematical equation. It's (torque X RPM)/5252. This means that the higher you make your torque in the RPM band the higher the HP figure. The stroke on the 4.0 is simply too long to rev high and it doesn't make torque high in the RPM band. This leads to good torque down low but artificially shitty horsepower figures. This is why the 238hp figure of our truck is quite misleading when regarding the abilities of the Tacoma. This is why it beats a lot of other trucks in a drag race when the numbers say it should lose (gearing helps too).

The 3.5L engine is likely a very similar bore and stroke to what's in the IS350 and or other Toyota vehicles. That size of a V6 really is the sweetspot for making power; many other manufacturers seem to agree. The engine should make plenty of torque but it will probably make it slightly higher in the RPM band. And that's ok. There's nothing wrong with an engine that CAN rev higher and makes power doing it so long as the vehicle's 1st gear is chosen to accommodate this. Think about it, after first gear you're no longer starting from idle rpm speeds...

Long story short, the Tacoma has never been short on power down low. For you offroaders, let's be honest, 4WD LO is geared low enough that a tiny 4cyl would be plenty of power to get you up some gnarly stuff. The only thing our current engine sucks for is fuel economy and passing power. That is EXACTLY where this new engine is poised to shine. And for anyone regularly towing 5,000lbs+ you're probably not thinking about doing it with a Tacoma anyway and a full size truck is your best bet regardless. So someone PLEASE tell me why Toyota was wrong for picking a 3.5?

 

They mentioned that the 1st gear in the manual transmission was lower. I assume the same is going to happen with the automatic.

 

HAHAHA. I'm reading through this tread seeing all of these HP and torque numbers posted, with my 2.7l I4 pumping out probably less than 100 hp, and definitely not near enough torque. Oh what I would do for 200+hp and 200+ torque...

I too, feel if you are regularly pulling 3500lbs+ up hills and mountains, you should be in a "Full Size" truck, or at least a V8 if you can find one in a midsize. Or, you need to start looking for boost. Especially if your complaint is that the RPM's are too damn high....

meme's in 3...2...1...

 

Cause I'm a nice guy...



I was thinking about selling my Tacoma and just borrowing my wifes F150 when I needed it. She said no deal, she loves the Tacoma too much to let me dump it

 

They all died off for a reason. The only guy I knew who bought a V8 Dakota ended up with a V8 F150 a year later. They both got the same mileage and the F150 was a way nicer drive plus it didn't have a seizure every time he towed with it like his Dakota did.

 

He is aware of that the V8 is no longer offered. He was just making a point that GM tried it and did not sell much.

 

Diddling around here with the calculator, using ItalionStylion formula from above, HP = (torque x RPM)/5252, I wish to see 310 torque/309 HP.

Here's the assumptions and what the calculator says.

Peak HP will come at redline, apx 5800 RPM, but peak torque probably will have dropped off some at redline. Let's assume 310 peak torque, which would be great IMO. That will come lower in the RPM band, probably drop significantly in the RPM range 5400-5800.

So let's say at 5800 redline the torque has dropped to 280 lbs. By the formula, 280x5800/5252 = 309 HP.

Let's say at 5400 RPM torque has dropped from 310 lbs to 300 lbs, 300x5400/5252 = 308 HP.

Those are my wish numbers.

 

Looking at the GM numbers for the 2015 3.6l, http://news.pickuptrucks.com/2014/0...s-for-2015-chevrolet-colorado-gmc-canyon.html

Peak HP 305 at 6800 RPM (wow, that's high RPM), peak torque drops off after peaking at 269 lbs at 4000 RPM as the RPM's wind up (typical). So GM is getting the 305 HP @ 6800 RPM with about 230 lbs of torque.

I hope Toyota can develop similar HP at much lower RPM because of a higher torque number.

 

I would buy a V8 taco..

 

I would.

 

The engine power and transmission will effect towing but the frame, wheelbase and suspension matter much more when it comes to towing capacity. You could shoehorn a 5.7 V8 in the Tacoma and it still couldn't come close to the same towing capacity of the Tundra due to the other factors stated.

 

Just make it a option. A lil 5.7 taco would be sweet.

 

Yes, but then you have to build all the little mechanical odds and ends for probably 5% of you truck sales. It's not worth it.
