I'm thinking the part in question is technically MGR3. But now I'm wondering if anyone has chopped down the transaxle casting to hold the two MGRs and bolt up to a clutch housing. For instance replace the Prius gas engine with a VW transaxle.
In case anyone hasn't seen it, here's the [very self-congratulatory] video for Titan America manufacturing the transaxle for the Arcimoto SRK.
This is twin motors into a 'black box' with half-shaft outputs. I will be meeting with the Arcimoto folks, maybe later this week.
