Both Daniel Ricciardo and Nico Hulkenberg’s RS19 have been fitted with Renault’s Spec-B engine, with the team holding onto Friday’s Spec-C units for later in the season.
Both drivers incurred penalties when they swapped engines on Friday at the Belgian Grand Prix, taking on the new Renault power unit.
However, the team announced on Saturday morning that Ricciardo and Hulkenberg were back on the older spec engines from FP3 onwards.
Renault revealed that the decision to run the new spec on Friday and revert to the older for the rest of the weekend was a tactical move.
“We have gone back to the Spec B engine for the rest of the weekend,” a Renault spokesperson told GPBlog.
“The plan is to take penalties at a track where there is a possibility to overtake, while entering a needed extra ICE into our pool for the rest of the year.”
Ricciardo was fourth fastest in FP3 with Hulkenberg 12th.
