After a few months on break and a few updates to the rules and teams, Formula E starts their fourth season this weekend with two races in Hong Kong – one on Saturday, one on Sunday.  Last year’s champion Lucas Di Grassi will see if he can defend his win from Sebastian Buemi, who was dominant all season but ended up in second place after missing two crucial races in New York City.  Buemi’s team, Renault e.dams, is back to defend their three-straight team titles – the only team to win a championship since the series began.

There are a few changes this year, but the technological changes are only slight, with max power output increasing from 170kW to 180kW.  The big shakeup will happen next year, as more manufacturers join the competition and the cars get a new chassis, new battery and 250kW of power.  Nevertheless, the racing should continue to be close and exciting as it has been since the sport’s inception in 2014.

There has also been a slight rule change that the extra point for setting the fastest lap can only go to a driver finishing in the top 10 positions – this is intended to stop a situation where uncompetitive cars drop to the back of the race and take a pit stop to change their configuration to set a fast single lap without trying to complete the whole race properly.  The former rule actually led to an exciting final race to the 2015-16 season, where the two championship-leading cars were tied on points but crashed out early in the race, then competed at the end of the race to see who could set the faster lap – but many race fans did not like the idea of cars racing amongst themselves, rather than racing against the entire pack, so the rule has been changed.

New races have been added for the year.  The series will not return to Monaco or Buenos Aires, but will race in Santiago, Chile; Sao Paulo, Brazil; Rome, Italy; and Zurich, Switzerland.  This will mark the first time any motorsport event has been held in Switzerland since 1954 (racing was banned in the country after the Le Mans disaster of 1955).

As is common between seasons, there have been some team changes as well.  Audi has increased their participation in the Audi Sport Abt Schaeffler team; Dragon Racing has dropped Faraday Future from their team name; NIO has dropped NextEV from their team name to focus on their NIO brand; and MS Amlin Andretti is now MS&AD Andretti Formula E.

Some drivers have swapped teams, some have left the series and some new drivers have joined.  Luca Filippi joined NIO to replace Nelson Piquet Jr. who moved to Jaguar to replace Adam Carroll.  Neel Jani takes Loic Duval’s spot at Dragon racing.  Alex Lynn relplaces Jose Maria Lopez at DS Virgin.  Andre Lotterer joins Techeetah in place of Stephan Sarrazin. Edoardo Mortara will start racing at Venturi.  And Robin Frijns’ seat at Andretti is now occupied by Kamui Kobayashi.
