Thank you for the update, PS!Toyota was testing a manual trans, this I know for sure. The last tidbit of information I got from a reputable source was that they stopped testing for technical reasons (i.e., NVH, comfort, weight, etc...). I was also told, that a different differential, axles, and rear subframe needed to be put in from the BMW parts bin. What happened, I don’t know. But let’s see what 2022 brings before we completely rule out a manual trans option.
All of this makes sense: another final drive ratio would be needed, probably the other subframe is the cheapest way to mount that other parts bin differential and the axles would need to be changed to fit the new differential’s different dimensions. Without having to design much more than minor fasteners or bushings from scratch to fit it all for production this sounds very straightforward on the mechanical end.
A little extra NVH is to be expected. Not a big deal.
Here’s hoping they push ahead and just do it at long last before MY2026.
