After a conference of FIA stewards, Renault has been disqualified from the Formula 1 Japanese Grand Prix, Motorsport reports.
Both cars were accused of using an illegal braking adjustment system on a day when they each scored in the points.
Motorsport says the stewards ruled that while the system itself was within the Formula 1 rulebook, it was enough of a driver aid to be outside the rules.
The complaint was filed by Racing Point.
Renault’s best race of the year came in the Heineken Grand Prix of Italy in Monza, where Ricciardo was fourth and Hulkenberg was fifth.
This should drop Renault in the constructor standings, and allow Alfa Romeo’s Kimi Raikkonen to leapfrog both Ricciardo and Hulkenberg in the driver’s standings.
