FIA could change USGP qualifying format to reflect smaller grid

Sebastian Vettel (front) is expected to miss qualifying due to a power unit change.

The FIA has the option to change the format of qualifying to reflect the 18-car entry that it is expected in Austin next weekend, with both Caterham and Marussia failing to make the trip.

Currently six cars are eliminated in both Q1 and Q2. With an 18-car field that would mean that only two cars would be bumped out in Q1 -€“ and with Sebastian Vettel having already stated that he will sit out qualifying due to a power unit change guaranteeing a pit lane start – in reality we could see only one car bumped in Austin.

However, the FIA Sporting Regulations include the provision for changing the number of cars that are eliminated. The numbers specifically referred to are eight for a 26-car entry, and seven for a 24 car entry. It follows that with an 18-car entry four cars would be bumped from Q1 and Q2.

The regulations refer to the size of the championship entry rather than that for an individual race. However sources confirm that once the stewards have officially been notified that only 18 cars are in the Austin field they will have the option to decree that four cars are eliminated in Q1 and Q2.
