It will be interesting to see dyno results from this "upgraded" N54 engine in the 335is, given that it's been confirmed by everyone (except BMW

) that the "old" N54 has been putting down 320 to 330 hp all along. Deliberately underrating engines from the factory is, after all, a time-honoured tradition in the automotive industry, so either the new N54 will prove to have more like 350 hp, or that the 335is has the same old N54 and the underrating is now acknowledged publicly by BMW (in a very roundabout sort of way).
Whatever, though. The numbers don't matter so much, really. What matters is that the N54 -- in any form -- is a superb motor. Yes, I own one and have nothing but praise for it: smooth V8 power, flexibility in every gear, and great fuel economy (I average 9.6 l/100 km in city/highway mixed driving, with a lead foot more often than not).
Oh, and the rest of the car is pretty damn good, too.
