BMW 7 Series Forum : “why doesn't bmw make an m7? merc makes s-class amgs and audi makes the s8.”

they have one. but it's made by another tuning company called Alpina. they also made a modified version of the Z8. The modified 7 series is called the B7. it costs around 110,000$ and it has a 4.4L V8, 32 valves, 500 hp @ 5500 rpm engine.
