The Renault F1 team has decided not to appeal the FIA's decision to exclude its cars from the 2019 Japanese Grand Prix, arguing that it would have no new evidence to present to the stewards.
Following a protest by Racing Point at Suzuka, which claimed that Renault's brake-balance system contravened the F1's technical rules, the FIA conducted an investigation into the matter.
Last on Wednesday, the governing body found that Renault's brake system did not violate the technical regulations but did breach the FIA's sporting rules as the brake-balance device constituted a driver-aid.
"We regret the Stewards’ decision and, in particular, the severity of the sanction applied," Renault said in a strongly worded statement issued on Thursday in which it waved its right to appeal.
"In our opinion, the penalty is not proportionate to any benefit the drivers derived, especially when used within the context of a system confirmed fully legal and innovative.
"It is also inconsistent with previous sanctions for similar breaches, as acknowledged by the Stewards in their decision, but expressed without further argumentation.
"However, since we have no new evidence to bring other than that already produced to demonstrate the legality of our system, we do not wish to invest further time and effort in a sterile debate in front of the International Court of Appeal concerning the subjective appreciation, and therefore sanction, related to an aid that reduces the driver workload without enhancing the performance of the car.
"We have therefore decided not to appeal the Stewards’ decision."
