Lucas di Grassi is set to take a second ten-place grid drop in as many races ahead of this weekend’s Mexico City E-Prix.
The Audi Sport ABT Schaeffler driver has been forced to take the penalty after a further break of the inverter seal on his Audi e-tron FE04 cars.
The reigning champion will therefore take a second successive grid penalty after Audi elected to again repair a component within the inverter after the Santiago event.
Di Grassi had already played his allowed component joker before the last race in Chile where he took his first grid drop of the season.
The decision to take a further penalty comes after forensic investigations by the team following the latest failure.
E-racing365 believes that a deep rooted problem from a key component supplier used by Audi has been diagnosed.
Di Grassi’s third successive retirement has left the Season Three champion with no points and out of contention for defending his title.
“Now, we’re confident that we’ve found both the cause and a solution,” said head of Audi Motorsport Dieter Gass.
“Unfortunately, the FIA regulations do not allow us to implement the changes until a 30-day period has expired.”
As a result, the update will not be used before round six in Punta del Este on March 17.
“Although we’re obviously not happy about this situation, we are optimistic that the permanent track characteristics, much like in pre season testing, do not exaggerate any problems,” concluded Gass.
