More horsepower, but not more torque?

True. HP is basically torque x rpm. Torque is what counts for a truck. 6400 RPM x 278 torque gets you 305 HP. 5800 RPM x 330 torque gets you 305 HP.

 

The 2GR gets peak torque at 4500rpms IIRC and the 1GR at 4000. The 2GR and 1 GR share the same family; I really wish Toyota just added the D4-S to the dual VVT-i 1GR. I think Chevy forced their hand this time; would be nice to see the 4.0 in 2017.

hp = torque (lb-ft) x rpm ÷ 5252

 

I didn't know the formula. Well done.

 

I believe the 4.0 has peak torque at 4,000 (266 lb ft) if running 87 octane, 3,700 (278 lb ft) if running 91.

 

it still doesnt matter.... the new motor is simply that a new motor... its not being used in any other vehicles. Its very likely based on a mating of technologies between the 2GR-FSE and 2GR-FXE but that is just a guess.... and even then you play with cam profiles and timings and you can go from a peaky hp motor to a very flat torque curve and very linear power quite easliy.

ALL we know at this point is.
1. 3.5L v6
2. D-4S Direct / port injection
3. capable of atkinson cycle / otto cycle depending on need

Beyond that.... nothing, no numbers, no specs, no name. you can guess all you want but untill specs are released its pointless to assume based on numbers of current motors.

 

Torque is what makes a 370hp Freightliner haul 80000lbs at 65mph, makes it that a 365hp Ecoboost F150 can't.

All HP isn't created equal.

 

Horsepower is how fast you hit the wall and torque is how far you carry it...torque is simply a trucks best friend...typically a higher revving motor will have higher horsepower less torque because the bore is bigger then the stroke. In the case of the 4.0l the stroke is bigger then the bore thus creating more torque then HP...I think the 3.5l has a bigger bore then stroke so I can assume the numbers will be 305hp and 278 lbtq at the crank. But we'll see still higher numbers then the 4.0l

 

You can't compare torque to HP. Two different things. Check out the above posts, HP is dependent on torque and RPM's. The difference b/t a diesel and gasoline engine isn't peak torque/HP, but where in the power band the torque/HP peaks.

 

The Freightliner, 370hp@2100 rpm, 1450ft/lbs@1100 RPM

An F1 car, 800HP@18000rpm, 400ft/lbs@17000rpm.

One will ultimately make you go faster than the other, but which one do you think is better suited in a truck? I know the two examples are extreme, but I think it gives you an idea why guys would like to have the chance to buy a small truck with a diesel.

 

^Since your truck is much closer in weight to the F1 car than the Freightliner, and most Tacoma owners prefer to accelerate faster than the Freightliner, you can see where this is going. It isn't much work to set a higher idle speed.

Performance of the Colorado diesel is expected to be poor, especially since the engine lost 20 hp compared to the Australian version, thanks to US emissions equipment. Even the Chevy fans are disappointed at the power numbers.

 

That would mean a bigger engine than the base V6 in the F150 (3.7L NA) and the Ram (3.6L Pentastar). I think CAFE targets are forcing all automakers to spec engines below what buyers necessarily want.

More CAFE stupidity: Lexus made the NX front bumper design uglier for the US market. The higher approach angle enables the SUV to be classified as a "truck" by CAFE rules, allowing greater fuel consumption without penalty.

 

I was happy with the speed my 160hp 2.7l gave me. I'm sure I would have loved it had this power come along 1000rpm lower, along with 170 extra ft/lbs of torque, 1500rpm lower, along with about 10 extra miles on a gallon fo fuel.

As it is, I never push the pedal of my 4L to the floor, except for towing. I've read way to many times on here, "it's a truck, if you want economy, get a Prius". To this, I add, it's a truck, if you want speed, get a FR-S!

 

Umm... you missed my point? HP and Torque are not comparable, that is all. Don't try to role me up into the diesel argument. Refer to Toyota's statement on why they didn't release a diesel; I wholeheartedly agree.

This.

 

I know, one is derived from the other. I also know that the lower the RPMs both show up, the better, from a drivability standpoint. I also know that to lower this RPM, you need displacement, turbocharging, or diesels.

 

Yes and no. Increasing combustion efficiency can allow smaller displacement engines to match larger displacement engines. D4-S is a perfect example of this; I don't think we will see a HUGE difference between the low end torque between the 4.0 and 3.5L.

Also, don't forget the new trans. A properly tuned transmission can more than make up for low end power. Depending on how Toyota designed the torque converter (multiplier) and how they geared the lower gears, the 3.5 can easily pull harder than the 4.0L.

And with all that said, we need to stop blaming Toyota for their decisions. The US emission standards are forcing car manufactures to choose smaller engines, and forget about the diesel.

 

10-4 on the US EPA...

 

+1. Could not agree more with Toyota's rationale for not offering it in the US. If you're a guy that's pissed about that, I get it, but you need to be contacting your congressional representatives & the President. It's them & state people like them (mostly in CA) that have allowed the EPA to enact regulations for U.S. diesels that are completely asinine.

That said, I currently own a HD Diesel pickup truck & have continuously owned one for the last 15 or so yrs. I hold a Class-A CDL. I drive the big guys some. I'm going to get rid of my current diesel pickup probably in '16, & don't plan on getting another. The cost of operating & maintaining them is insane compared to a gas powered vehicle.

It's easy to romanticize owning a diesel but a 'mother' to economically justify it.

 

Did this thing get punched in the jaw?

 

As far as CAFE is concerned, the top one is a "car" while the bottom one is "truck". The "truck" is subject to looser avg fuel economy requirements.

 

It would be amazing if it was a 6 cylinder version of the NX 200t's FI setup. I think...
