|Formula E on the BBC|
|Watch the Rome E-Prix from 14:30 BST on Saturday, 13 April on the BBC Red Button, Connected TV, the BBC Sport website and BBC iPlayer.|
Six races, six different winners, from six different teams.
It has been a thrilling Formula E season and the European phase of the campaign begins on Saturday with the Rome E-Prix - you can follow live coverage on the BBC.
Portugal's Antonio Felix da Costa holds a one-point championship lead over Belgium's Jerome D'Ambrosio.
Reigning champion Jean-Eric Vergne is third after winning in Sanya, China, with Britain's Sam Bird in fourth spot.
Bird, who was forced into an early retirement in China having gone into the race top of the standings, is hoping to repeat last year's race win in Italy.
"Winning last year was such an amazing feeling, especially in front of such passionate motorsport fans," said the Englishman. "Of course, it would be great to do the same again this year, but we'll just have to see.
"The competition is seriously high this season with just 10 points currently separating the top six drivers, and all six races so far have seen a different winner, so it's really open.
"As always, qualifying will be key, but if we can get this right and start from the front then we have the car and the team to deliver."
You can watch live coverage of the Rome E-Prix on the BBC Red Button, Connected TV, the BBC Sport website and BBC iPlayer from 14:30 BST on Saturday, 13 April, with a full replay of the race available on the BBC Red Button later on Saturday.
Formula E has been to Saudi Arabia, Morocco, Chile, Mexico, Hong Kong and mainland China this season and the Rome E-Prix starts the European leg of the season, with forthcoming races in Paris, Monaco, Berlin and Bern before the season-ending double-header in New York.
This will be the second race to take place in the Italian capital and the 2.87km track, which consists of 21 turns, is one of the longest of the season.
The start/finish line is located on Via Cristoforo Colombo, with the cars racing around the Obelisco di Marconi, against the backdrop of the iconic Colosseo Quadrato.
Recap: How does Formula E work?
Compared with Formula 1, Formula E is considerably more friendly to the environment.
The sport was developed with sustainability in mind, with organisers saying the aim is to "reduce our carbon footprint as much as possible".
It does this by powering its cars with a battery that uses 100% renewable fuel, and tyres that, as well as lasting an entire race, can also be recycled afterwards. Meanwhile, spectators are encouraged to use public transport to get to events, with no public parking available.
One drawback with battery-powered cars had been that they lacked the capacity to last an entire race, resulting in the rather unusual (and somewhat gimmicky) sight of drivers having to swap cars mid-race.
That will no longer happen - this season's Gen2 car is fitted with a battery that will last from start to finish of races.
With the car manufacturing world looking to switch to developing almost exclusively electric cars within the next couple of decades, Formula E provides them with the ideal arena to test new technology at a competitive level.
Fan Boost and Attack Mode
Spectators play a key role in the action during Formula E races.
'Fan Boost' has been a feature of the past few seasons, with viewers able to vote using an app to determine which driver gets some extra power during a race.
New this season is 'Attack Mode', which gives competitors a speed boost after they drive through an allocated area on the track.
How are the big names doing?
Former Ferrari and Williams driver Felipe Massa, runner-up in the Formula 1 world championship in 2008, has signed a three-year contract to race for Monaco-based Venturi and is 15th overall after coming 10th in Sanya.
It has been a struggle for Stoffel Vandoorne, Fernando Alonso's F1 team-mate at McLaren for the past two seasons, in his first year in Formula E as he has only collected three points from six races for the HWA Racelab team.
Mahindra Racing's Pascal Wehrlein, who had two seasons in F1, is 10th overall after coming seventh in China. He led throughout the race in Mexico City, but in an incredible finish ran out of battery power in the final straight and was overtaken by Lucas di Grassi. Wehrlein was also handed a five-second penalty to drop him down to sixth.
