Basic Variances:
There are various trims for the Supra which will vary based on factory standard/optional, local regulated equipment and geographic location.

Weight Descriptors:
GVWR: Gross weight rating of vehicle (all axles). This is the max recommended load ontop of the vehicles curb weight.

Curb Weight (Kerb European spelling): The weight of the vehicle with all standard equipment and fluids w/fuel.

Kerb ECE: Is the estimated weight of the vehicle assuming driver and typical luggage of 165lbs (75kg).

Now the question is why is the US Spec heavier and what can we RIP OUT?

Now the question is why is the US Spec heavier and what can we RIP OUT?

Exactly! The easiest to identify in this case would be to (1) compare fuel tank size which will increase material and overal curb weight when filled to a greater capacity. (2) The US has a strict standard for bumper and roof crush-testing which could mean more mass related to reinforcement.

There's also a difference in insulation requirements and preferences between countries.

I wonder if the batteries are the same abroad .

True - wonder if we get bigger battery and different starter because of the crap Start/Stop thing? hmm

Weights are basically the same. Notice there is no EEC listed for USA except for one. What you are showing is the difference in how weight is published between countries.

Fuel tanks are the same size between UK and USA. 13.7 gallons (52L)

They must've added weight to the 2023 models because I have never seen a 3.0 premium tested at 3460 lbs. Also if tested cars had half a tank(6.85 gallons) that would only be a 40-45 lb drop in weight.

For what its worth, someone just posted the weight of a 2023 A91 MT on this forum and I believe it was around 3350 lbs. That should be consistent with earlier years. I don't know how to explain that 3460 figure for the AT because I think that only weighs 20 pounds more, 40 at most.

Auto vs Manual

So I found the pic of the fully loaded a91 mt 2023 3.0 Premium with a full tank of gas vs a 2021 3.0 Premium with slightly less gas in the tank.

So the 23 premium manual in the Supra is only 10 lbs lighter on the front end than a 21 premium automatic. But the automatic in this pic has about 10 lbs less weight in the rear than the manual(gas is the likely culprit).

23 Manual 3.0 Premium F/1735 R/1618
21 Auto 3.0 Premium F/1745 R/1608

I'm wondering if the 21 auto is missing a quart of oil because I thought the difference on the front half should be more than 10 lbs.

Basically not the same. Your image shows a range for the UK models which demontrates there is a difference in between and within trims.

The info shared in the OP has all been "published" the same (Via Toyota pres). Countries must legally disclose this information as it is directly related to the regulations the vehicles must comply with (materials, safety, structure, etc). This disclosed number cannot be underestimated as that would affect emission compliance.

Regarding fuel capacity: you are correct. I misinterpreted the US Gal and UK Gal (volume measures) for capacity differences. The note has been removed.

Correction to fuel: US gal and UK gal hold the same capacity but have different values. So, the fuel tank capacities are actually the same (52L).

Regarding the battery, maybe someone from the UK or JP provide confirmation of the Autostart/stop feature (and battery mass)?

Basically the same. There is not 200lbs+ difference between the countries. Every real world Supra that has been scaled proves this.

Document world or real world. It’s a choice.

I have noticed a few users/sources with less weight than what's being shared by Toyota also

Good images. Here is the OP

I have the A91 MT edition as well and will be measuring soon. I'll try to find someone locally with the AT.

I too wonder if the weight increased slightly in 2023.

What im understanding then, is that "Basically the same" you mean "similar"? Because if thats what you mean, I agree with you. Similar models and trims will have similar mass/weight. The term "basically the same" is not precise or objective thus leaving room for many interpretations.

There is still a variance of 109lbs (between the 3.0 models). This variance makes a difference for many reasons, and thus not the same. Either way the purpose of the OP was not to give an opinion on how similar or dissimilar the models are, it is a reference point.

I was curious so I took a look at the MY23 Australian Spec sheet and I think you are right. The published weights are really just approximations. On Australian cars there should be a weight discrepancy between the GT and GTS specs due to different wheels as well as a few other minor spec changes.

Looks like standard marketing bullshit to be honest.
