Ah, the age old question of which is faster: a car or a motorcycle? We’ve seen the answer debated countless times on internet forums to no avail, and it seems at some point every publication in both the two-wheeled and four-wheeled realms tackles this issue in their own way. BMW recently took up the challenge to see which was faster, and the answer was painfully simple: the BMW…we jest. Here’s the setup though, two of BMW’s fastest machines, a BMW M3 & BMW S1000RR, start at opposite ends of an unknown course. There is a kicker though: part-way through, it starts raining. Make your guesses now as to whom won the race, and watch it unfold after the jump.
