Kimi Raikkonen could be forced to start from the back of the grid for tomorrow's Abu Dhabi Grand Prix after the Finn's car failed post-qualifying scrutineering.
The Lotus failed a floor deflection test, which was also undertaken on Nico Hulkenberg's Sauber.
The FIA released a statement saying:
"After qualifying practice session an asymmetric LHS (Left Hand Side) front floor detection test was carried out on car numbers 07 and 11 according to Article 3.17.5.
"Car number 11 was in conformity with Article 3.17.5 of the 2013 FIA Formula 1 Technical Regulations.
"However car number 07 did not comply with Article 3.17.5 of the 2013 FIA Formula 1 Technical Regulations as the front floor deflected more than 5mm vertically when the load was applied to it at the point which lies 100mm of centre line on the LHS."
While the car has failed the test there is a precedent for Lotus to explain the failure. At the Hungarian Grand Prix, the Lotus' other driver, Romain Grosjean, failed the same vertical load test but the team successfully argued that it had been as a result of damage caused by the kerbs at the Hungaroring.
Lotus officials are currently meeting with the stewards.
