 The circuit consists of long straights and tight corners, and features the characteristics of a typical street circuit - narrow, bumpy and limited overtaking opportunities.However, there are two special features that can rarely be found in other street circuits - variation in altitude (over between highest and lowest point of the circuit) and an ultra long main straight that allows top speed of on Formula Three cars.As a result, the circuit is recognised as one of the most challenging circuits in the world in terms of both driving and tuning, as cars have to maintain competitive speed to overcome hill-climbing, twisty corners and long straights in a single lap.
