Two FIA World Endurance Championship rivals battled for pole position on the streets of Monaco today with Sebastien Buemi (e.dams-Renault) starting from pole position for this afternoon’s Monaco ePrix ahead of Audi Sport ABT’s Lucas di Grassi.

Buemi is the reigning FIA WEC World Champion for Toyota while di Grassi drives for Audi in the sportscar championship.

However, today’s battle wasn’t without controversy as the top two drivers in the championship standings had a disagreement in qualifying parc ferme.

Long Beach winner Nelson Piquet Jr (NEXTEV TCR) set the early pace in the opening qualifying group with a 53.712s. The first group on track contained some key championship contenders including di Grassi who narrowly edged in front of Piquet to steal provisional pole position.

After the session Piquet complained about being blocked by his fellow-countryman going into La Rascasse on his final attempt. He will start fourth alongside Daniel Abt (Audi Sport ABT).

Loic Duval (Dragon Racing) qualified fifth but will drop 10 places for replacing the RESS system. Virgin Racing’s Jaime Alguersuari and Karun Chandhok (Mahindra Racing) also move back on the grid for the same infringement.

Duval’s team-mate Jerome D’Ambrosio got within two-tenths of di Grassi on his first flying lap but improved on his final attempt to beat Piquet into third place.

Miami race winner Nicolas Prost (e.dams-Renault) will line-up sixth with Mahindra Racing’s Bruno Senna seventh. The Venturi pairing of Nick Heidfeld and Stephane Sarrazin ended the session in eighth and ninth with Salvador Duran (Amlin Aguri) completing the top-10.

The final qualifying group was interrupted by a red flag following a crash from Amlin Aguri’s Antonio Felix da Costa. The Portuguese driver ran wide at Tabac and damaged the rear of his car.

Traditionally in motorsport pole position in Monaco is crucial with limited overtaking opportunities but this is Formula E’s first visit to the Principality so only time will tell if that notion remains the same.

The Monaco ePrix starts at 16:00 (local time) and can be seen live in the U.S. on FOX Sports 1.
