, was a

that took place on 23 May 2015 on the purpose-built
Tempelhof Airport Street Circuit
in
Berlin
. It was the eighth round of the
2014?15 Formula E season
. A special anti-clockwise track was built for the race next to the terminal building of the closed airport, including 17 turns over a distance of 2.469 km (1.534 mi).

led the Teams' Championship in front of second placed
Audi Sport ABT
.
Jarno Trulli

pole position
, but eventually retired. The race was initially won by championship leader Lucas di Grassi. After di Grassi's car was found to have used a modified front wing, the victory was handed to second-placed
Jerome d'Ambrosio
. As a result of the race, Nelson Piquet Jr. took the lead in the drivers' championship.
Background
[
edit
]
On 11 July 2013, it was announced that the newly founded
Formula E
, a class of
auto racing
for
one-make
,
single-seater
,
electrically powered
racing cars, was set to race in
Berlin
on the apron of
Tempelhof airport
,
[3]
which was closed in October 2008.
[4]
In April 2014, the race was included in the
FIA
's final calendar.
[5]
Prior to the ePrix,
Formula One
had visited Berlin in
1959
for the
German Grand Prix
held at the
AVUS
highway track, a race marred by the death of Frenchman
Jean Behra
, who died in an accident during a
Formula Two
support race.
[6]
[7]
Local politicians in Berlin supported the race, with the Senator for Economy, Technology and Research,
Cornelia Yzer
saying that Berlin "as the capital of
electric mobility
" was predestined for such an event. However, the
Senate of Berlin
did not agree to the organiser's plea to be allowed to hold the race at the central
Straße des 17. Juni
street overlooking the
Brandenburg Gate
.
[8]
Coming into the race from
Monaco
two weeks earlier,
Lucas di Grassi
(
Audi Sport ABT
) was leading the championship with 93 points, four ahead of his compatriot
Nelson Piquet Jr.
(
NEXTEV TCR
). Another six points adrift, third placed
Sebastien Buemi
(
e.dams Renault
) was the only driver who scored two victories over the course of the season, but less consistent outings prevented him from placing higher up in the standings.
[9]
In the teams' championship, e.dams Renault on 160 points had a 45-point lead over Audi Sport ABT.
[10]
The circuit
[
edit
]
The 2.469 km (1.534 mi) anti-clockwise circuit was designed by Rodrigo Nunes, featuring 17 corners.
[11]
[12]
It was described as a "twisty and challenging circuit" by Formula E driver
Nick Heidfeld
(
Venturi
), who also stated that "overtaking will not be easy" due to the nature of the course.
[12]
Construction of the track started 14 May, nine days prior to the race.
[13]
World record
[
edit
]
Between qualifying and the race, a new world record was set for the largest parade of electric vehicles, when 577 cars and scooters took to the track. The parade surpassed the previous record set in September 2014 in
Silicon Valley
,
United States
.

Report
[
edit
]
All sessions took place on Saturday, 23 May 2015,
[1]
in contrast to Formula One, where all sessions are divided up over a three- to four-day period.
[16]
Free practice
[
edit
]
Cars pass through turn ten.
Two free practice sessions were held before qualifying, running for 45 and 30 minutes respectively.
[1]
The first session started at 08:15 local time, with Sebastien Buemi topping the timesheets for
e.dams-Renault
in a time of 1:23.158.
[17]
The track got faster as the temperatures rose and more cars drove around the circuit; lap times improved by more than a second in the second session, which started at 10:30. This time, it was championship leader Lucas di Grassi who topped the timesheets with a lap time of 1:22.032.
[17]
Qualifying
[
edit
]
In contrast to other racing series such as Formula One, Formula E has a specific qualifying mode, in which the twenty drivers are divided up into four groups, leaving enough space on track for everyone to produce lap times without interference by other drivers. Each group had ten minutes on track and the fastest time of each driver determined the grid position. A lottery determined which drivers started in which group. With five-minute breaks between the groups, qualifying had an overall length of 55 minutes.
[18]
Racing veteran
Jarno Trulli
(
Trulli GP
) started in the first group, as qualifying began at 12:00, and posted a strong time of 1:21.547 early in the session, being the first to lap the course in under 1:22. Also in the group was Nelson Piquet Jr. ? second in the championship ? who ultimately managed only 13th place on the grid. As qualifying progressed, championship leader Lucas di Grassi and Monaco winner Sebastien Buemi came close to beating Trulli's time, but proved unable to do so, handing Trulli a surprising
[19]
pole position
, his first in Formula E.
[20]
Race
[
edit
]
A special feature of Formula E was the "Fan Boost" feature, an additional 30 kilowatts (40 hp) of power to use for five seconds during the race. The three drivers, who were allowed to use the boost, were determined by a fan vote.
[18]
For the Berlin race, Nelson Piquet Jr., Sebastien Buemi and
Charles Pic
(NEXTEV TCR) were handed the extra power. For Piquet, it was the third boost in a row, while both Buemi and Pic were able to use it for the first time.
[19]
Local driver
Daniel Abt
spun early in the race, leaving him out of the points.
At the start of the race, Lucas di Grassi challenged Jarno Trulli for the lead, but Trulli closed the racing line into turn one. As Trulli lost the rear end of the car going into turn three, di Grassi took the lead. The other Audi Sport Abt of
Daniel Abt
was less fortunate, being sent into a spin at the same corner, dropping to the back of the field. Nelson Piquet Jr. immediately made up for ground lost in qualifying, gaining three positions during the first lap, running in tenth place. At turn six on the following lap, he went past
Stephane Sarrazin
(Venturi) for ninth. While di Grassi built an early lead, several manoeuvres were made behind him, with
Nicolas Prost
(e.dams-Renault) losing two positions to
Jerome d'Ambrosio
(
Dragon Racing
) and
Vitantonio Liuzzi
(Trulli GP), dropping back to seventh. Pole sitter Jarno Trulli looked to be in trouble with his car and lost positions continuously, running in thirteenth after lap twelve. Third placed Nick Heidfeld was also unable to hold onto his podium position, being overtaken by d'Ambrosio on lap thirteen.
Loic Duval
finished third, his first podium finish in
Formula E
.
The mandatory pit stops, during which all drivers needed to change into a second car,
[18]
started on lap 17. Everyone came in at this point except the two NEXTEV TCR drivers Piquet and Charles Pic. D'Ambrosio managed to get ahead of Buemi into second place thanks to swift work from his crew. Piquet benefited from his late stop by moving ahead into eighth after everyone had pitted and having more power left to use towards the end of the race. Heidfeld ran into additional trouble during the second half of the race, losing two positions during the final laps to both
Loic Duval
(Dragon Racing) and the fast running Piquet, who managed to finish fifth from thirteenth on the grid, even closing on Duval on the final lap. Meanwhile, di Grassi won comfortably from d'Ambrosio, the gap being more than twelve seconds.
[19]
Post-race
[
edit
]
After the chequered flag fell, Lucas di Grassi's car stopped on the way back to pit lane.
[19]
Once his car returned to
parc ferme
, it failed post-race scrutineering, and was found to have a modified front wing, leading to his disqualification.
[21]
This meant that Jerome d'Ambrosio was handed his first Formula E victory, moving him into fifth place in the drivers' championship. Nelson Piquet Jr. recovered from his "dismal" qualifying performance to finish an eventual fourth, taking the championship lead.
[19]
While e.dams Renault retained their lead in the teams' championship, the strong result for the Dragon Racing squad meant they moved up into second.
[22]
The Abt team decided not to appeal the decision against Di Grassi, while emphasizing that the front wing did not lead to a performance advantage.
[23]
Di Grassi himself responded on
Twitter
, writing: "They are trying to make me win this championship in the hard mode. Don't worry, we will be back to kick some Piquet and Buemi ass on track."
[24]
D'Ambrosio was delighted with the result, commenting: "It was a great weekend for us overall. I think in the last four races we've had the pace to be on the podium but we didn't always manage to put it all together in the race. [...] This time we did it and it paid off!" He however added regret about the fact that he and the team were unable to celebrate the win and a double podium at the respective ceremony.
