Because it is easier to get a good launch, the x-drive has a better 0-60 time, but the 335i will over take the xi at about 135mph. Most of the numbers I see put the difference to 60 at about 0.2 seconds. Overall, there have been some great Dyno comps threaded on this site which indicates the two engines (n54 and n55) as being essentially identical in terms of output.
