The first part of the track is very fast with two straights where the DRS is used. Then, beginning from turn 11, the number of tight turns increases, keeping the cars from reaching 186 mph on the rest of the track.
The race begins at 5 pm in daylight but when the sun sets half an hour later, the last hour is contested under artificial lighting.
This dramatic shift translates into what can be a 27°F drop in temperature, which reduces the grip and results in unstable braking performance.
In the first half hour of racing under the boiling hot sun, grip is high as is the temperature of the braking system. This can cause thermal discharge problems and wear down the friction material.
According to Brembo technicians, who have classified the 20 tracks in the World Championship on a scale of 1 to 10, Yas Marina Circuit is one of the world's most demanding tracks on the brakes.
The Arab track earned a 10 on the difficulty index, the same score given to the circuits in Montreal, Mexico City and Singapore.
