I'd be surprised if BMW would provide Morgan with their latest big twin motorcycle engine as they just came out with it for their R18. Would a different front suspension be needed to clear the wide engine? BMW did a great job on the looks of that engine (looks like their pre-1970 Boxer), it would need to be out on display at the front.
The only V-twin engine that I know of that is mass produced, offered for sale independently from the bike, EU5 compliant (expected), would be Harley's M8 engine. As many here already know, they offer a water cooled heads version which would be good for low speed driving and a functional radiator would look right at home siting behind the V-Twin as has been done a 100 years earlier. With Harley needing revenue, I don't see why they wouldn't want to sell a few hundred or so a year to Morgan. Now to make the next 3-Wheeler a bit larger all around (more interior room) and a fix/remake for the Centa. Regarding MotoGuzzi's smoother fireing 90degree V-Twin, I don't know if they offer engines separately for use by other manufactures, If they would do so with the standard gearbox, it would save some weight along with the expected more interior room.
As many here would agree, it's that V-Twin engine out in the front which makes this vehicle so interesting, a the quintessential Morgan 3-Wheeler needs a V-twin. I personally wouldn't care much for a hidden engine 3-Wheeler, though I can Morgan going with a BMW car engine as they have with their latest 4 wheelers. The 1.5 3cyl turbo with BMW supplied gearbox would be a logical choice when paired with a CX style chassis.
So will the next 3-Wheeler be evolutionary or revolutionary? Perhaps evolutionary in styling on the outside and revolutionary in engineering under the skin?
