 Although the track has seen some minor changes as seen above, the basic layout has in many aspects remained unchanged.It is a twisty circuit that is the slowest in Formula One running at normal race distance above , which combined with its features of proximity to walls leads to frequent safety cars, further extending the running to nearing the race time limit of two hours.The bumpiness, the heavy braking zones, the lack of daylight and the humidity makes the race very testing for both drivers and cars.
