Lucas Di Grassi stormed into Formula E title contention after flying to victory in Berlin.

The Audi star, who won the championship in 2017, made quick work of passing front-row pair Sebastian Buemi and Stoffel Vandoorne before powering to the finish line.

He now sits just six points behind drivers' leader Jean-Eric Vergne, who went from seventh to third in the latter stages to ensure he kept his top spot.

Di Grassi said: "It is still very early to say for the title because there are still five or six drivers very near. "Basically anyone who wins a race comes straight back into the Championship.

"You can probably go down all the way to eighth and if they win then they’re straight back into the fight.

"I think there will be five to seven people still fighting for the title when we get to New York."

Here are the key talking points from the race...

Di Grassi ensures Audi win battle of German big beasts on home soil

Di Grassi celebrates his victory in Berlin

Audi Sport ABT Schaeffler made it two wins in two years on home soil as Season 3 champion Lucas Di Grassi claimed his second win of the season to hand bragging rights to his team in the battle of the German big beasts Audi and BMW in Berlin.

Di Grassi’s victory saw the Brazilian roar back into title contention just six points of reigning champion Jean-Eric Vergne. The 34-year-old never looked in any danger of losing the lead after overturning Sebastien Buemi and Stoffel Vandoorne from third in the first seven minutes of the race.

With BMW i sponsoring the Berlin E-Prix, the Audi garage were treated to the sight of BMW’s Head of Marketing handing over the winners’ trophy to Audi’s Head of Motorsport Dieter Gass on the podium before the Moet and Chandon was sprayed.

Experience has clearly been key with the only two double-race winners this season being former champions.

Vergne wins the battle of DS Techeetah

Vergne extended his lead at the top of the championship

Much of the talk heading into Berlin was around teammates Vergne and Andre Lotterer who sat first and second in the Drivers’ Standings just a point apart and whether team orders would have to come into play.

But a typically tenacious drive from the reigning champion Vergne, finishing in third place after starting in eighth, ensured the Frenchman cemented his place in the title race with a polar opposite day to his teammate.

After a horror qualification which saw the German start 21st, Lotterer began a steady climb up the grid until a failure of his battery forced him out of the race pointless. He now sits 16 points behind his teammate Vergne and will need a big score in Bern to keep team orders at bay.

Breakaway pack form in Drivers’ Championship

The leaders are beginning to break away in Formula E

In one of the most unpredictable seasons of motorsport ever, many drivers said they expected up to ten different drivers to be in close contention for the title when the Championship reaches the double-header in New York City.

Vergne ominously extended his lead at the top of the Championship to six points ahead of Di Grassi and Lotterer a further ten back. BMW i Andretti Motorsport’s Antonio Felix Da Costa kept with the chasing pack with a fourth place finish that puts him 20 points of Vergne with Envision Virgin Racing’s Robin Frijns another point behind.

The next closest racer is Panasonic Jaguar Racing’s Mitch Evans who sits 33 points away from Vergne with just three races to go this season.

Former champ Buemi back to the boil in Germany

Nissan's Buemi in action during the Berlin E-Prix

Once the all-time point scorer in Formula E, a champion in Season 2 and runner-up in each season either side of this – Sebastien Buemi has suffered some lean times since his last race victory exactly two years ago at the 2017 Berlin E-Prix.

A fourth placed finish and no race wins last season represented a poor return for the Swiss and things have gone from bad to worse this season with no podiums, sitting in 13th place and being out-driven by his rookie teammate Oliver Rowland.

But returning to a track he has won twice on before, been runner-up once and fourth on last year Buemi fulfilled all the clichés around form and class as he put in an imperious qualifying performance to take pole.

Despite losing out to Di Grassi, a hat-trick of second-place finishes in Berlin saw the Swiss back to the podium after a year absence and completing a podium comprised of former champions for the very first time.

Kings of qually Nissan e.dams continue unwelcome streak

It has been another difficult day for Nissan

Exactly half the races this season have seen a Nissan e.dams driver take pole in qualifying – Oliver Rowland with three and Buemi with two following his performance early in the morning in Berlin.

But the team continued an unwelcome streak with another victory slipping through their grasp. The team are yet to take a victory since Nissan took over the e.dams team as manufacturer despite their five pole positions.

In better news for the team, the points scored by Buemi and Rowland in Berlin lifted Nissan above Mahindra Racing to fourth in the Team Standings.

Attack Mode continues to play its part

Di Grassi pulls away from the pack during the Berlin E-Prix

Following the race Buemi admitted that he found Attack Mode ‘really hard’ and with the position of the zone on the far corner of a wide bend, plenty of drivers saw positions lost when activating the mode.

The zone, which gives a 25kw boost to the car battery twice a race when the car is driven through it, has had a huge impact on races this season with drivers being forced to regain positions after departing the racing line.

And it contributed to another hugely exciting race with teams admitting Attack Mode strategy is now playing a major role in their own preparation.
