Must suck for some of you especially with this relatively large bump for the 650i, heck its half an engine grade of performance.
The regular 5 doesn't get it because its still too new, they don't need it yet to keep up the sales. Which begs why the 6 and 6GC, I guess its because of their premium pricing, and vs. competitors etc.
On the other side, the 1st year F10 528 got the N52/3 engine with 258hp which is the same as the 530 now, same torque and only 14hp less. Price was also lower.
