“The ZF transmission can handle the torque of a V12...”
The family of ZF transmissions can handle it, but there are numerous (20+?) versions of that transmission. IIRC we get the same one as this engine gets in the Z4/Supra model. It’s probably ‘OK’, but it isn’t ‘overengineered’ like I’d like it to be an as far as I understand, ins’t the same model and specs as to what you’d use a for a V12.
