Never, supercar must be a flatplane crank and naturally aspirated version on that engine cant be excluded, but still I think Bmw go for high revving turbocharged engine, like Mclaren Mp4
I prefer S65 Block, but Naturally aspirated and ITB, Flatplane crank, peak power about. 580bhp.
When has BMW ever built a road going, flat plane crank V8?
