Daniel Ricciardo is under investigation by the FIA stewards for a potential breach of the fuel flow limit rules.
FIA technical delegate Jo Bauer reported Ricciardo’s car “exceeded consistently the maximum allowed fuel flow of 100kg/h”.
“As this is not in compliance with Article 5.1.4 of the 2014 Formula One Technical Regulations, I am referring this matter to the stewards for their consideration.”
Under new regulations introduced this season a driver’s engine may not consume fuel at a peak rate higher than 100kg per hour.
The FIA had experienced difficulty in monitoring the fuel flow rate limit on cars earlier in the weekend. Yesterday the teams were advised by race director Charlie Whiting of a change to the fuel flow filter frequency.
“Due to time constraints before the qualifying session the FIA data versions will not be changed [to the new frequency],” Whiting added. “The revised monitoring will be processed by the FIA offcar.”
Red Bull had changed the fuel flow meter on Ricciardo’s car before the race. The same component was not changed on Sebastian Vettel’s RB10.
