F1 drivers have started to put millions into electric motorsports, including seven-time world champion Lewis Hamilton and Mexican Red Bull driver Sergio Perez, and viewership numbers have increased following it.
Since Formula E came to the scene, new electric versions of other racing series have started, such as Extreme E which is an electric rallying series which was started by the same investors from Formula E. It is also expected that we will see the introduction of electric boat racing called E1 next year.
Hamilton has started the X44 Extreme E team for the electric rallying series as well as former F1 driver Nico Rosberg, who owns the Rosberg X Racing team. Following his former F1 rivalries is Jenson Button who is starting a team as well, called JBXE, which he is also going to be driving for. Going to the E1 electric boating series, Perez has started a team for the water sport which will race in the debut year of the sport.
We have recently seen from reports that the viewership of Formula E has increased again with their best viewership numbers to date. A series of changes have led to higher viewing ratings as well now that the sport will be getting back to a more true form of racing with them rumoured to be taking away the Fanboost system which enabled fans to vote for their favourite drivers in order to give them more power.
Hamilton and Rosberg have both said in interviews that part of the reason they decided to start their teams in Extreme E was due to the lower environmental impact as well as the more sustainable way the sport will be held.
