I believe BMW hasn't released any official info on the new engine as of yet. All we know so far:
400bhp @ 5800-6250 (approx according to memory)
450lb-ft @ 1800-5200 (again according to memory)
The rpm range I listed might be off a hundred or two, but that's the basic gyst.
Past:'08 E92 335i|ZPP|ZSP|6AT|four (4) HPFPs
Present:'15 Mustang GT|401A|PP|6MT|Recaros
Sig pic unrelated. I like to go sideways and stuff.
