Subaru has had some pretty high spec 2.0/2.5L turbocharged Boxer engines too, but we've been getting just the 2.5L variants in the U.S. so I'm not sure what they've gotten their 2.0L engines up to in other markets. I know they've hit 300hp, though.
The base 740i in the U.S. is running the N54/N55 at 315hp/330tq now, although I'm not sure which engine it is, the N54 or the N55. I'm guessing the 5er will see those specs in a few years when they update.

The 4G63 is an ancient lump (debuted nearly 20yrs ago) yet those engines are tough (some UK-spec Evos run over 400ps out of the box). Also, the Subaru EJ20 first reached 250ps for non-STi WRXs for MY1995, so 240ps is considered as upper average (current JDM Impreza STi has 300ps from their 2.0 engines).
The 740i in ROW/EU-spec uses N54 & puts out 326ps/450Nm, & the new 640i uses N55 & puts out 320ps/450Nm.
