Lucas di Grassi secured a provisional pole position for Saturday's ePrix in Santiago de Chile, but the Audi driver's spot at the front of field is under investigation for a technical infringement.
The Brazilian put in a flawless lap under the blazing sun during the top-six super pole shootout, edging Nissan e.dams' Sebastien Buemi by 0.526, who had crashed heavily in practice, and Mahindra's impressive Pascal Wehrlein by 0.635s.
The former F1 driver and Mercedes protégé, running in his second Formula E event, had topped the initial group qualifying session to secure his place in the shootout.
The German edged Buemi, di Grassi, Virgin Racing's Sam Bird, HWA Racelab's Stoffel Vandoorne, who reached the Super Pole phase for the first time this season, and Audi's Daniel Abt.
Di Grassi's infringement and the subsequent investigation is linked to his opening run in the group session in which he finished second.
Morning practice pacesetter José Maria Lopez qualified 11th, while Formula E championship leader Jerome d'Ambrosio was nowhere to be seen in qualifying, the Marrakesh ePrix winner finishing the grid-defining session well down the order in P21, penalised as an early group runner by a very dirty track that clearly undermined his efforts.
