Likely to be based on the advanced CLAR platform with CFRP construction.
Rumors of a BMW 9 Series Coupe are now swirling around the web, which was first reported by German publication AutoZeitung.
As of now, the report states that BMW hasn't finalized on a design for the 9 Series Coupe, although it's likely to draw inspiration from the BMW Vision Luxury Concept, which also influences the BMW 7 Series.
It will, reportedly, be based on an aluminum intensive CLAR platform with CFRP (carbon fiber) construction that could also be shared with the next generation Rolls Royce Phantom. Power is likely to be sourced from the familiar 3.0-liter petrol and diesel engines, 4.4-liter V8 turbocharged unit or a hybrid powertrain.
It's unclear as to why the ultra luxury coupe is rumored to be called the "9 Series", given that BMW uses odd numbers for practical, sedan-style models (3-Ser, 5-Ser, 7-Ser) and even numbers for sporty models (2-Ser, 4-Ser, 6-Ser). However, they did break convention when the 2 Series Active Tourer was christened.
