Ricciardo gets Hungary grid drop after getting new Renault F1 engine

Ricciardo was only due to start 18th after a miserable Saturday at the Hungaroring, where a run-in with Sergio Perez at the end of Q1 caused Ricciardo to be eliminated in that segment.

Renault has decided to take the opportunity to switch Ricciardo to a completely fresh power unit.

That means Ricciardo moves onto a new internal combustion engine, MGU-H, turbocharger, MGU-K, energy store and control electronics.

Ricciardo now exceeds his limit for the season for each of those components, so the matter has been referred to the stewards.

F1's sporting regulations state that the first time a driver exceeds their limit on a specific engine element they will receive a 10-place grid penalty.

Ricciardo's total penalty for exceeding the limit on six different components requires him to start from the back of the grid.

Renault would not divulge the specification of engine Ricciardo has now taken when approached by Autosport.

Earlier this weekend, Renault F1 boss Cyril Abiteboul said the team was poised to take grid penalties, but would tie them into the introduction of a new-spec engine.

Abiteboul admitted it was "not a stupid guess" to suggest the upgraded engine would be ready for the power-sensitive tracks of Spa and Monza, after the summer break.

That suggests Ricciardo has switched to a fresh existing-spec engine, which would add another set of components to his pool for the rest of the season and would make no difference to any plan to take grid penalties at Spa or Monza to introduce the upgraded spec.

The changes in Hungary also mean the next time Ricciardo takes a new engine component, it will result in slightly smaller penalties.

Although taking a first new element above the season limit triggers a 10-place grid penalty, subsequent additional elements only carry a five-place drop.

That could represent a small bonus in the future, unless Renault makes multiple changes at once.
