Toto Wolff is forecasting a “very strong” performance by Ferrari after the summer break.
The Spanish publication said the new engine should deliver a 20 horsepower boost.
Even without considering the new engine, Mercedes boss Wolff said he already expected Ferrari to be strong at the high-speed circuits that await after the August break.
“In Hungary it was clear that the Ferrari was not well adapted to the circuit,” Wolff said.
“But they have a very powerful engine, so we should see a very strong Ferrari at Spa and Monza. We’ll have to work hard to be competitive.”
