I used the allocation lists here o the site and AI to track down a mostly clean build and a dealer that is transparent, does not raise price over msrp or add on the 3k dealer options.
So my argument with AI started and im curious how much is true and not true. is PT4wd a platform code or part time 4wd indicator. Do certain builds have dual transfer cases?
an example vehicle i visited in person showed 2wd trd sport prem also having the JTEVA5 vin.
According to AI A5 is 2wd and B5 is 4wd only.
I can see many A5 ORP 2026 allocations and a few B6, Dealers list it as part time 4wd and AI says its their form and its wrong.
Wanted to ask real owners to review this and give feed back if the A5 is really a part time 4wd and the button that looks like a Diff Locker is really A-TAC or traction control on A5 vins vs B5 that have true lockers?
This is the AI statement or hallucination if you can confirm or deny any of this nonsense.

The key characters are:
A5BR
B5BR
â B = 4WD
There is no scenario where an Aâseries VIN has:
2. So why does the build sheet say 4WD with transfer case?
Because Toyotaâs internal system uses generic trim descriptions, not VINâspecific equipment.
Hereâs what happened:
The system saw âTRD OffâRoad Premiumâ
and automatically printed the 4WD versionâs description, even though your VIN is 2WD.
This is extremely common with:
But the VIN determines what the vehicle actually is.
3. The build sheet is NOT VINâspecific
Itâs a trimâlevel spec sheet, not a VINâdecoded equipment list.
It describes what a TRD OffâRoad Premium 4WD would have, not what your specific VIN has.
Thatâs why it lists:
4. Your VIN cannot physically have those features
A 2WD 4Runner:
5. The VIN is the final authority
Toyota VIN coding is extremely strict:
JTEVA⊠= 2WD
JTEVB⊠= 4WD
There are no exceptions.
If the VIN starts with A, it is not 4WD â no matter what the build sheet says.
Bottom Line
Your build sheet is showing the generic TRD OffâRoad Premium 4WD description, but your VIN is 2WD, and the VIN always wins.
The sheet is wrong
The VIN is correct
Your vehicle does NOT have:
ow to read the engine type in a 2026 4Runner VIN
Toyota encodes the engine family in the 5th character of the VIN:
5 = Gas (iâForce 2.4L Turbo)
6 = Hybrid (iâForce MAX)
So the patterns look like this:
Apply it to your VIN
JTEVB5BRâââââââ ââââââ5 = gas engine
So this VIN is:
This is a 4WD gas TRD OffâRoad Premium â not a hybrid.
Bonus: TRD OffâRoad Premium is never hybrid
Toyota does not offer the iâForce MAX hybrid on:

Toyota encodes the engine family in the 5th character of the VIN:
So the patterns look like this:
| VIN Pattern | Meaning |
|---|---|
| A5BR / B5BR | Gas turbo (NOT hybrid) |
| A6BR / B6BR | iâForce MAX hybrid |
- A = 2WD
- B = 4WD
- 5 = gas
- 6 = hybrid
JTEVB5BRâââââââ ââââââ5 = gas engine
So this VIN is:
- JTEV = Toyota SUV
- B = 4WD
- 5 = gas turbo
- BR = TRD OffâRoad Premium body code
Toyota does not offer the iâForce MAX hybrid on:
- TRD OffâRoad
- TRD OffâRoad Premium
- TRD Sport
- SR5
- Limited
- Platinum
- TRD Pro
- Trailhunter
