The first day in Shanghai Grand Park for the Formula E Championship opens today with the debut of the first race of the season.
Formula E, which has been running in Shanghai for a year, has been aiming to get into the race by the end of the year.
This is the first Grand Prix of the new era of the series and it will kick off with a two-day event, on Thursday.
There will be eight cars, with the drivers in the lead in each, competing for two-and-a-half hours, with some 20,000 spectators at the track.
There will be a pit stop on Friday morning, with two of the top teams, Renault and McLaren, making their first start.
There is also a live telecast of the race on Saturday morning.
F1 has long been a driver-driven race series, with many drivers taking part in events, with McLaren, for example, racing in Formula E in 2013 and 2014.
The sport is now being overseen by a new series called F1: Proving Grounds, which is overseen by the FIA.
The race has been promoted as a showcase event for the world of Formula 1, with F1 Proving Ground Shanghai featuring live coverage of the races on BBC Two and online via F1-Proving Grounds.
The event is set to attract around 10 million viewers.
On the grid is the world-record pace of Renault, which won the championship in 2018.
It is the second time in the season that the team has won the title.
Its pace and reliability is proving to be key to the team winning the title, which was held in 2018 and was contested by Ferrari and Mercedes.
McLaren will be hoping to continue its lead over Mercedes in the championship with a strong result in Shanghai.
Renault has been on the back foot for much of the campaign, losing three races in a row.
The team had only two wins in the first two races of the championship, and it lost the last race, in Hungary, due to mechanical issues.
Its engine supplier, Marussia, was also not able to provide a reliable supply of power to the car.
Marussia is now in administration, having been taken over by Renault, but the team is still hoping to make a recovery.
Mercedes has struggled this season, losing seven races and a race in Spain.
Its car was deemed unsuitable for the first round of the 2017 season, and its lack of performance at the last two races has led to speculation it will be dropped from the grid.
