Red Bull may protest Ferrari engine in 2020

The official Red Bull Team crying towel

(GMM) Dr Helmut Marko says Red Bull will "definitely protest" if the legality of Ferrari's engine once again becomes a hot topic in 2020.

The German broadcaster RTL quotes team boss Christian Horner as suggesting F1's governing body struggled to stay on top of the "very complex" engine technology last year.

"I think the FIA does not have the expertise that the teams have," he said. "So it was extremely important for us to have clarity for 2020."

Indeed, the situation become calmer in the latter part of last season following a series of clarifications issued by the FIA.

Ferrari, however, denied that it changed anything about the basic operation of its engine, even though its major engine advantage appeared to wane.

"There were several points with Ferrari's engine that were likely to be beyond any grey area, but nothing was done about it," Marko told Germany's motorsport-total.com.

Red Bull and Mercedes were open about being behind the vigorous mid-season push for the FIA to act.

"The increase in performance was blatant," Marko said. "It was always only on certain laps. But I assume that such things will not happen this year.

"If we do suspect that there are irregularities again, we will definitely protest," the top Red Bull official warned.
