|Binotto knows his secret is in the fuel and the batteries|
(GMM) Mattia Binotto is daring Ferrari's rivals to lodge a protest against the Italian team's 2019 power unit.
There are rumors that key rivals suspect the engine could be illegal.
"We're talking about 50 horsepower on the straights," Red Bull team boss Christian Horner is quoted by Blick.
The Swiss newspaper's veteran correspondent Roger Benoit says one team has already asked the FIA to look into the situation with Ferrari's engine.
Ferrari team boss Binotto reportedly hit back: "They should protest!
"Then we could all see how stupid their allegations are and the rumors would disappear."
Binotto is more focused on turning Ferrari's obvious qualifying advantage into more race victories.
"We have six consecutive pole positions but three victories in the last six races," he said. "We want more than this.
"But it is undoubtedly an improvement over how we started the season. We see the last three races as a test bench to learn to operate in the best possible way for next season."
