. Had a stern warning today, "Wolff said." They have a great power unit. We were good in all types of turns, but we are not able to match their performance in a straight line. "

Wolff added," We need to find out how we can improve our energy production. "

" It's a worry. If others are able to do it, we should be able to do it.

For the first time in F1, Ferrari rather than Mercedes currently has the most powerful engine in F1 – an update that propelled the Scuderia to the top Both championships and customers driven Sauber and Haas on the ground .

"They took a step after Monaco," said Wolff. "From Canada, there was a tremendous increase in power for qualifying and the start of the race. I pay tribute to them because it is a big change.

"If we knew we would do the same thing Our brains spin to try to figure in.

" The greatest power we see is the acceleration off corners. It's not at the end of straight lines but especially in the mid-speed corners. It's there that they did a good job. "

Red Bull boss Christian Horner added," They are doing a great job. Their engine is now the reference. "
