I asked this question to the former M-brand manager at BMW NA (also the current X5 brand manager) tonight at a BMW CCA event at DeSimone BMW here in NJ tonight. He said the US models have usually have slightly less horsepower than the European counterparts due to they way they are tested. However, he did not know of any delays in production of US models due to California emissions.
