The 11 braking points at Abu Dhabi together with the sweltering heat

11/19/2018

Yas Marina has three braking sections that last more than 2.5 seconds

​​​The 21th and last race of the Formula 1 World Championship is scheduled for November 23-25 at Yas Marina Circuit in Abu Dhabi. The track is on the man-made island of the same name, next to Ferrari World, in the area north-west of the capital of the United Arab Emirates.


 

The first part of the track is very fast with two straights where the DRS is used.

Then, beginning from turn 12, the number of tight turns increases, keeping the cars from reaching 186 mph on the rest of the track.

The race begins at 5:10 pm in daylight but when the sun sets 20 minutes later, the last hour and 15 minutes 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.

The first 20 minutes of racing are 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 21 tracks in the World Championship, Yas Marina Circuit is one of the world's most demanding tracks on the brakes.

The demand on the brakes during the GP

Even though there are 21 corners, the drivers only use their brakes 11 times each lap.

Only the city tracks in Singapore and Monaco have more braking points, 15 and 12 respectively.

The brakes are used for a total of 18.5 seconds each lap, which equals 17 minutes over the course of the whole race, 20% of the GP.

The average peak deceleration per lap is 3.9 G, but taking into account just the first 11 corners, the average exceeds 4 G, a figure that is reached only in the last turn.

The energy dissipated during braking in the whole GP from each single-seater is 213 kWh, which is quite similar to the US GP.

From the starting line to the checkered flag, each driver exerts a total load of 58 metric tons on the brake pedal.

On the single lap though, the load exceeds 10.5 tons.


 

The most demanding braking sections

Of the 11 braking sections at Yas Marina Circuit, four are classified by Brembo technicians as very demanding on the brakes, three are of medium difficulty and four are light.

Preceded by the almost 0.75-mile long straight, the second most challenging braking section is turn 8: The single-seaters arrive at it going 201 mph and then brake for 2.81 seconds to slow to 46.6 mph. They manage to do this in 162 yards by applying a load of 253 lbs on the brake pedal and undergoing a deceleration of 4.8 G.

A more challenging corner comes after the second sector where the DRS can be activated, turn 11: The drivers need just 143 yards and 2.57 seconds because they arrive going slightly less fast (197 mph) and enter the corner going a bit faster (59.6 mph).

Almost identical are the load on the brake pedal and the deceleration. The third most important corner in terms of time and space is turn 17, where the single-seaters go from 174 mph to 59 mph: They need 2.51 seconds and 121 yards, but the intensity of the force on the drivers is lower than at turn 5. This last turn requires a deceleration of 4.8 G and a 253-lbs load on the brake pedal, despite a reduction in speed of "just" 97.5 mph, from 181 mph to 83 mph.


 

Brembo performance

Single-seaters with Brembo brakes have won seven of the last nine Abu Dhabi GP races disputed up to now: 3 wins for Red Bull and four for Mercedes.

The most successful driver is Sebastian Vettel with three wins; none of the Ferrari drivers have ever been able to secure the pole position on this track.
