I was browsing the BMW internations web page and reading through the refreshed 550i and m5 touring and to my surprise the performance numbers for the 550i have been updated. The refreshed 550i runs 0-100kph in 5.2 vs 5.5 for the last one although the engine and transmission (and body structure) are identical!!! Any ideas???
