Formula E has revealed its updated London E-Prix. The update is set to have a mixture of technical as well and energy-saving parts on the track.
One of the biggest updates to the London E-Prix is the alterations made in Sector 3. This has been done in order to promote energy saving in race cars. Turn 16 in sector 3 is now a heavy braking zone as drivers head into the hairpin.
Often teams need 30-35% energy to reach the finish. However, with the addition of new and heavier braking teams believe that drivers would need as little as 5-10% energy to reach the finish.
Heavy braking zones are a characteristic of this track. As we look at the chicane at 1 and 2, and the reversed hairpins at turns 10 and 11 (now clockwise). Post the hairpins at 10 and 11, the chicane at turns 12 and 13 have also been added so as to mitigate the top speed as the drivers reach the hairpin at 16.
With the possibility of the increased safety car in the flat-out sprint, the FIA responded by deducting 4kWh from the total energy each car can use. This will certainly decrease energy use.
Following the preliminary analysis of the London circuit and the energy consumption, it was noticed that the lift-off requirements would not be significant enough with a 52kWh capacity.
“As the management of the energy consumption is key to the ABB FIA Formula E World Championship, and to avoid flat-out races, it has been decided to reduce the total amount of available energy to 48kWh for the races of London.
“The double-header this weekend, which will be broadcast live on Channel 4, marks the returns of London to the Formula E calendar after Battersea Park last featured for the 2015-16 season finale.”
To increase the effectiveness of saving energy the track has also been shortened by 1.3 miles.
