New BMW X5M and X6M will arrive at showrooms this September so the Bavarian firm is gradually starting out the marketing plans for them. And what plan better than having your tame Formula1 driver publiciting your car! That’s what Nick Heidfeld, BMW’s number one driver, does in this video. The 4.4 liter turbocharged V8 unit in this car develops 555 hp which is good for 0-60 time of 4.7 second and limited top of 155mph.
