N45B20S
The N45 was enlarged to 1,997 cc (121.9 cu in), to homologate the E90 320si for the World Touring Car Championship.[3] The N45 was chosen over the N46, because its lack of variable valve lift allows higher engine speeds. Instead, the engine used dual overhead camshafts and 16 valves. The main visual difference is the carbon fiber valve cover.
Applications:
- 2006 E90320si (Limited production model)
