To be clear, rear diff spec for the J250 hybrid in the US market have not been published.
We do know that
- the non-hybrid Tacoma and J250 (non-hybrid, non-US market) will get 8.2;
- the Tacoma Trailhunter Hybrid, J252 and J300 get 9.5;
- Toyota upsized rear diffs on hybrid vs. gasser Tundras too.
But we don't yet know diff size the J250 hybrid (US market).
The hybrid, given its torque, may well be paired with a 9.5, like Tacoma hybrid, or possibly an 8.7. Or, perhaps torque distribution of Land Cruiser's AWD is sufficiently supported by an 8.2 (which has been bombproof in 4Runner). We'll see. No matter, I trust Toyota's engineering.
The rear diffs on the prototype LC250s that have been shown in the US
- appear different than that used in LC300 and J252 (GX550);
- are of unknown size;
- are not the 8.2 used in 4Runner; and
- may not reflect production.
