BMW is putting their 3L engine in a lot of cars, under a lot of variants.
135i, 335i, 535i, X3 35i, M135i, M340i, M3, M4, 335is, Z4 35is, 1M etc ...
Bingo- but its more than cash, they have not developed a turbo to replace it in a timely manner. Let's not forget that Audi RS models were always turbo then they more recently used this engine across models to compete with naturally aspirated offerings from BMW and MB bc the turbo RS models were always viewed as lesser cars for being turbo. Now Audi is going to react once more and go FI again.
