We have good basic platform and this you need to develop an M car, but it took two years for us to come up with the M5. One and half years of this time was spent on developing the engine. There is such a passion at BMW M to do things to the best that many times you are, say, leaving work at 9pm and there are still people all around you. I have to say to people to go home.
