Could Toyota be understating the TTV6's payload to make the hybrid more comparable?

So I came across this recently showing the GVWR and payload capacity of 2 identical Platinums with the only difference being that one is the TTV6 and the other the hybrid.



As you can see, the hybrid's curb weight is 385 pounds more but has 20 pounds more payload. Then you look at the GVWR, and the hybrid is rated for 405 pounds more than the TTV6. What gives? Shouldn't the GVWR be almost identical? As far as I'm aware, they're identical trucks just with different powertrains. From my understanding, GVWR is based on suspension, tires, the truck's frame, etc. So why is the hybrid rated for hundreds more?

So I got thinking, maybe they understated the TTV6 so the hybrid doesn't look so bad in comparison. Cause if they both had the same GVWR, it would look something like this:

If they both had the TTV6 GVWR of 7,375:

TTV6: 1,575
Hybrid: 1,190

If they both had the Hybrid GVWR of 7,780:

TTV6: 1,980
Hybrid: 1,595

See how that could quickly steer someone away from the hybrid?

Maybe someone knows something more than I do to counter what I'm seeing. I'm not an engineer, so I'm basing this simply on these numbers and knowing how businesses use numbers to sell products. But I could easily see this being the case.

 

I have heard it mentioned in the reveal videos last fall that the hybrids have a heavier rear axle to deal with the torque. You can see that by the ground clearance numbers, the hybrids, including the TRD Pro, have 1/2 inch less ground clearance.

 

Interesting. Haven't heard about that, but that could very well explain it!

 

The hybrid is 385 lbs heavier, has a 405 lbs higher GVWR, and has a 20 lbs higher payload capacity? Makes sense to me. I think Toyota’s focus was likely ride quality so they didn’t bother to put the hybrids stiffer springs on the non-hybrid in order to increase payload.

 

i am also missing where the discrepancy is.

 

Ford does the same thing with the powerboost. The Powerboost has 7350 lb GVWR vs the standard crew cab 4x4 are 7050 lbs. But Fords payload numbers suggest the powerboost is 500-570 lbs heavier

 

Could they? Definitely.

Are they?

¯\_(ツ)_/¯

 

If they were both exactly the same, the GVWR would be exactly the same. A heavier truck doesn’t mean a higher GVWR. A more capable one does.

 

But I looked into what VZMotion said and it holds up so that seems to be the case.

https://news.pickuptrucks.com/2021/10/how-the-2022-toyota-tundra-went-from-4-suspensions-to-6.html

“Sackett said all six suspension systems are available with either Tundra engine — a turbocharged 3.5-liter V-6 or, in the Tundra hybrid, the same engine plus an electric motor sandwiched between the engine and transmission. The Tundra hybrid gets unique suspension tuning due to weight differences, but the “end result is to be the same” ride, Provost said.”

 

So like I said, if you put the hybrid suspension on the non-hybrid, the ride gets harsher. The frame and axles can probably take more load but likely the suspension will bottom out due to softer springs and the system will be underdamped due to more weight. So there really should be a payload package with the hybrids springs and dampers for people desperate to have 2000 lbs of payload and a ”truck” ride.

 

Would really be a nice package to have. I know Ford at least has that for the F-150, and I can't imagine it would be a crazy addition to make to the assembly line.

 

Its due to the size of the rear end to handle the torque of the hybrid motor
