MEXICO CITY -- Renault's cars have been disqualified from this month's Japanese Grand Prix after they were found to be running illegal driver aids.
After the race at Suzuka two weeks ago, rival team Racing Point protested the legality of Renault's brake-bias adjuster -- a system on all F1 cars that determines the split in braking force between the front and rear brakes to help turn the car into the corner and prevent locking a brake. On the basis of on-board video footage, Racing Point argued that Renault's brake bias was changing without any driver input -- something which it believed was in breach of Article 27.
