Former Toro Rosso Formula 1 driver Sebastien Buemi topped the final day of FIA Formula E pre-season testing at Donington Park.

The e.dams racer posted a session best of 1.31.792s to end the final test on top before the series embarks upon its inaugural event in China next month. Buemi has topped four of the five tests at the Leicestershire circuit.

“We’re really happy with today, especially being the last test before Beijing,” said Buemi.

“We still have a few issues with the car which we need to work on and also to better understand the limits of the car.

“Overall we’re feeling good for the first race but we’ll have to wait and see, a lot of teams are also looking quick.”

Nicolas Prost, the son of four-time F1 world champion and e.dams co-owner Alain Prost, was second fastest just three tenths adrift of his e.dams team-mate.

Andretti Autosport’s Franck Montagny was third fastest with Mahindra Racing’s Bruno Senna fourth and Virgin Racing’s Sam Bird fifth.

Only half a second split the top five as the championship’s 10 teams completed 1,222 trouble free laps throughout the day.

Abt’s Lucas di Grassi trailled Bird by a thousandth of a second in sixth, while India’s Karun Chandhok was seventh.

Jerome d’Ambrosio set the eighth fastest time for Dragon Racing ahead of the Venturi duo of Stephane Sarrazin and Nick Heidfeld, who completed the top 10.

Chinese racer Ho-Pin Tung made his Formula E test debut with China Racing as he shared the running with sportscar ace Antonio Garcia, who set the fastest time of the pair.

Nelson Piquet jr also enjoyed some seat time behind the wheel of the other China Racing car, as the squad continues to evaluate its options for their two vacant seats.

Andretti Autosport are the only other team with a vacant seat ahead of the opening round at Beijing on September 13.

Former Marussia and Caterham F1 driver Charles Pic driver took over the duties of the second Andretti car for the day, while Japanese IndyCar driver Takuma Sato drove Antonio Felix da Costa’s Amlin Aguri entry.
