Payload: 1687 lbs (GVWR 6725 lbs - Curb Weight 5038 lbs)

Fuel capacity: 17.9 gallons (disappointing)

MPG: 23 combined (22/25/23) -- 22 city (and dirt road) is not too shabby.
Damn 17.9 gallon tank and only 23mpg combined…kinda kills it for me…assuming 7/8ths tank is really “usable”, you have a range of between 350 and 400 miles. I was really hoping it would be the 21 gallon tank in the gx550 and 24-25mpg combined, which would give closer to 450 miles

At least the curb weight is only about 5000lb Not 6000lb.

Idk the efficiency is surprisingly low for a turbo 4 hybrid, and they couldn’t even give us a big fuel tank…they might have lost me.
 
Sometimes the emission aystem are not the same. Like charcoal canister was not required on a lot of other market. At least on previous models. Trying to retrofit subtank on 120 is difficult without causing check engine light.
 
With a little luck, the GX 550 or 300 Series main and sub tanks will swap in with minimal effort. The sub tank mounts forward of the rear axle axle, just like the main. Very small, though, only 8 or 9 gallons.

I think this is going to be a direct fit, Brian.

I'm curious, do we know how the OEM sub tank functions? Is it primarily a transfer pump into the main tank?

Do we know?

"A jet pump, which automatically transfers fuel from the fuel sub tank assembly to the fuel tank assembly, is provided in the fuel tank assembly on models with a dual fuel tank."

  1. The dual fuel tank model uses a jet pump.
  2. A jet pump has been provided to transfer the fuel from fuel sub tank assembly to fuel tank assembly.
  3. This is accomplished by utilizing the flow of the fuel through the jet pump, so that the pressure difference, which is created by the fuel as it passes through the venturi, is used to suck the fuel out of fuel sub tank assembly and send it to fuel tank assembly.

Bernoulli at its finest! I imagine there's some vapor pressure equalizing lines between the two tanks.

Am I correct in saying there is no fuel return line from the engine?
 
The parts schematics appear to be for the GDJ25#, so is it fair to assume the schematics are specific to the diesel 1GD-FTV? Would there there be any differences between these assemblies (tanks, pumps, etc) for petrol versions?

Yes and market-specific as well.

TJH250 does not have a dual tank option (TJH250 will be the US designation).

TJA250/TRJ250/TJA251 will all have dual tank options.
 
@OGBeno are the new car features available yet? Interested in the 8 speed (AL80?), t case, and axle size.

  • An AL80F 8-speed automatic transmission (direct shift-8AT) is used.
  • A lightweight, compact and highly efficient 8-speed gear train is used.
  • A dramatically improving start-off acceleration performance by using a low gear ratio for the 1st gear and fuel economy at high speeds by using high gear ratio for the 8th gear. Also, a close gear ratio is used for the low gear positions to achieve rhythmical gear changes. Furthermore, the transmission constantly selects the optimal gear ratio to achieve improved fuel economy in situations such as city driving.
  • The gear train is composed of 2 planetary gears. Also, the gear train uses an aluminum parts, achieving weight reduction and compactness. As a result, superior packaging is also ensured.
  • An oil level detection mechanism (overflow method) is used. For details of fluid filling and adjustment procedures, refer to the Repair Manual.
  • On models with 48V system, due to the use of stop and start control, an electromagnetic oil pump (oil pump assembly with solenoid (EMOP)) is installed in the transmission valve body assembly. When the engine is restarted after an idling stop is performed by stop and start control, the oil pressure required for the clutch and brake engagement is supplied to make smooth starting off possible. For details, see the 48V SYSTEM section.

  1. OUTLINE
    1. A compact and lightweight full-time 2-speed VF4CM transfer is used.
    2. The 4 wheel drive control ECU actuates and controls the 2 shift motors in the transfer shift actuator assembly. This causes the VF4CM transfer to switch the transfer gear ratio between high and low and the center differential between free and lock.
    3. On the models with AL80F automatic transmission (A/T), the transfer position switch is used to switch the transfer gear ratio between high and low, and the center differential lock switch is used to switch the center differential between free and lock. The optimal drive mode is selected from 4 drive modes (H4F, H4L, L4F and L4L) in accordance with road surface conditions by operating these switches, thus enabling a drive that makes optimal use of drive torque performance.
    4. On the models with AC60F A/T, the transfer position switch is used to switch the transfer gear ratio between high and low and the center differential between free and lock. The optimal drive mode is selected from 3 drive modes (H4F, H4L, and L4L) in accordance with road surface conditions by operating these switches, thus enabling a drive that makes optimal use of drive torque performance.
    5. A low viscosity oil is used, also improving fuel consumption

Did we ever confirm the front diff and rear axle size for the LC250 TJH version?

I'm surprised that it drops 800lbs vs the GX550. I was guessing the hybrid weighs more than the V6 powertrain. Where is all that extra fat getting cut? I imagine it'll be a bit quicker than the GX 0-60 given the power to weight ratio along with EV drive having a lot more power immediately off idle. Probably also quicker than the LX.
 
I tried plugging the VINs that are showing in the online inventory into the MyToyota Service History to pull vehicle details and it isn't recognizing the VIN. The NHTSA site came up with some results although the VINs don't appear to be fully valid, yet.(https://vpic.nhtsa.dot.gov/decoder/Decoder)

Here are the VINs I quickly located:

JTEABFAJ2R109BI35
JTEABFAJ5R109BI45
JTEABFAJ0R109BI48

The Toyota website includes this note about the availability for these VINs: (Vehicle may be in transit. Estimated availability 04/13/24 - 05/08/24.)
 
With the 250 curb weight only being ~5k lbs.(and that’s including the weight of the battery), and the GX having a curb weight of 5,600-5,700 lbs. I wonder where they cut the weight between the two.

Also, only a 6k tow rating now instead of 6,500? While the GX gets a bump on the tow rating of 9k lbs?
With this low curb weight {if this is correct} it is almost guaranteed it have smaller diff. I don't mind the smaller diff and giving higher ground clearance. The 8.2 in GX460 are pretty durable. Even more durable compared to the elocker version.

As for the front even the old 8" front clamshell are plenty strong. I hear people blowing CV all the time but I don't remember hearing somebody blowing the 8" clamshell. RLCT truck running 40" tires are still running this diff.

Tacoma seems to have BD24 on MT equipped version. The rumor saying all hybrid getting BD24 might not be true.

What is weird the overtrail might get smaller front diff compared to other model that have 3.307 gear ratio.

BD21 might be for the upcoming hybrid like LC250

Let the dealer adjustments begin..

Just take note of these dealers and route all business you might conduct with Toyota, and any referrals of everyone you talk to, away from these businesses.

I don't patronize the Toyota dealer near me that does markups with any service or parts requests, and definitely not vehicle purchases.
