Power unit designer Ferrari: "Led to advantage estimated at over one-tenth per lap

Erico Gaulteri, power unit director at Scuderia Ferrari, has explained the new power unit of the Italian team during the official unveiling of the Ferrari SF21. He predicts that the steps made with the power unit will result in a gain of at least a tenth per lap over last season.

Gaulteri begins by acknowledging Ferrari's dramatic season in 2021: "In our sport, you have to be continuously aware of the areas where you can improve, the points that you can improve. You have to continuously think about your lessons and experience, learn from your defeats. And then you work hard, with humility. This awareness, along with our passion and skills and the skills of our technical partners is what created the power unit 065/6," he said in the official Ferrari launch video. 

Improved on all points

Gaulteri continued his explanation, "Along with the chassis engineers we have worked considerably on the layout of the power unit, trying to make the overall project for the car as efficient as possible. We continuously worked on the internal combustion engine aiming to increase its thermal efficiency, which has led to an advantage estimated at over one-tenth of a second per lap."

"The turbocompressor has been revised, to meet the needs of the engine and at the same time, we have planned to increase efficiency in the recovery of exhaust fumes. We’re also working on the hybrid system, on the electronic part, trying to revise all its components and optimising them," concludes the Ferrari engineer.
