Rally1 hybrid cars (2022-)

Tyres? Currently some of the transmission parts are shared?

I don't think there are any transmission parts that are shared. Ford use Sadev, Hyundai use Ricardo, Toyota use Xtrac.

Tyres, there is some similarity, but they are obviously far more vulnerable to both bad luck and driver error. They're also much more of a known quantity than hybrid power units. I can't think of many situations where it can be proved beyond doubt that a tyre has failed because of a manufacturing or design fault.
