Tom Dillmann and Loic Duval both attended tests for NIO last month as the Chinese-entered team continues to evaluate drivers for the upcoming ABB FIA Formula E Championship season.
Both drivers were at a test in Spain ahead of NIO giving current Williams Formula 1 development driver Oliver Rowland a test later this month.
While Dillman conducted laps, Duval’s time in the cockpit is understood to have been compromised, meaning the former Dragon driver could undertake a re-test shortly.
The 2013 Le Mans winner has competed in 28 Formula E races, scoring a best result of third in Berlin and London in 2015. He was replaced by Neel Jani at Dragon ahead of the 2017-18 season.
Duval currently races full-time for Audi in DTM and TDS Racing in the FIA World Endurance Championship LMP2 category.
His compatriot Dillmann, who subbed for Venturi’s Edoardo Mortara at three rounds last season, took a career-best fourth in the first race in New York City earlier this year.
E-racing365 understands that presently NIO is likely to start the season with an unchanged lineup of Oliver Turvey and Luca Filippi but is keen to bolster its reserve, development and simulator driver ranks in addition to its current lineup of Ma Qing Hua and Harry Tincknell.
Filippi has accrued the most miles in testing NIO’s Gen 2 car so far after Turvey picked up an injury in New York which ruled him out of driving for several weeks.
NIO did not respond to e-racing365’s request for comment when contacted this week.
