Should be normal (harmless) - Many others have noticed the same symptoms after some hard track driving etc.

It seems as if some excess oil pools in some areas of the motor and finds its way into the combustion chambers and when the car is started this small amount of oil just burns off.

BMW motorcycles have been known to do the same thing due to their flat cylinder orientation as well, especially if left for extended periods on their side stand - which tilts the motor to one side.
