Sorry know this is slightly off-topic but what will be the i3/i8s codenames? Or will they even have them? Back on topic, will BMW consider an 8-Series based on the next gen CFRP/Aluminium intensive structure? And would the new X7 be based on the forthcoming F15, or the next-gen 7 Series?
The i3 and i8 are simply known as i3 and i8.
If you are wanting a large Coupe in the mold of the old E31 8er , then you already have the successor its called the 6er. The 6er fullfills the brief of a large GT coupe.
If you want a V12 Coupe like a rival for the Mercedes-Benz CL/S-Klasse Coupe? Then you have to wait for the upcoming Rolls-Royce Ghost Coupe which will be a more sports orientated model than before but still with that Rolls-Royce ambience and exclusivity.
The Rolls-Royce Ghost Coupe will also be joined by a DropHead Coupe model adding a more romantic open-to the elements experience.
Both models have been previewed by special customers who have since put deposits down for these new models in the opportunity to be first. We expect these models to be very popular on launch perhaps on a par with the Ghost which means you to still have to wait around 12 months for a Ghost due to demand.
Expect Coupe and drophead Coupe to be even longer.
Should BMW consider an automobile above the 7er it will be a four door like the CS , progress in the global market has determined that.
I am not entirely sure if the X7 is based on the new modular architecture developed from the X5 to accomodate the next generation of BMW SAV's with key material technology used from the next 7er larger car family.
The X7 is a big car that kind of looks like a larger Touring , a comparison with the Audi Q7 is fair. But The BMW is more sporty looking with its swept back roof which adopts a kind of floating roof like the MINI or indeed a Range Rover at the a-pillar.
The car is deliberately not meant to imitate the Range Rover interms of outline , like the Bentley that looks as if the English Footballers wives traced over a Range Rover with crayons for the details.
But luxury will be on a par with both , The BMW will also have exclusivity with a V12 engine , although BMW will concentrate more on the on-road aspects like all X models , although off-road prowness will be durable.
