There are rumors from Munich saying that BMW is considering a 9 Series Coupe model for production. German magazine AutoZeitung also published information about this possibility but right now, nothing has been confirmed.
If the 9 Series Coupe becomes a reality, it would be based on the platform of the next generation Rolls Royce Phantom and to offset its footprint it will make use of CFRP for the passenger cell. The design is still being explored, but the Vision Future Luxury Concept will certainly have some influences on the potential 9 Series concept. Suicide doors are also said to be part of the recipe.
Inside the cabin, the high-tech seen in the new 7 Series and also in the Vision Future Luxury Concept will likely be used, along with higher premium materials and trims.
BMW considers a series of powerplants to be used for the luxurious limousine, starting with the 3.0 liter turbocharged, petrol and diesel, and continuing with a V8 4.4 liter TwinTurbo. A hybrid version, 940e, is also said to be part of the release plan.
