Franz Tost has talked up the technical skills learned at Ferrari as being crucial to Dniil Kvyat's impressive return to racing with Toro Rosso in 2019. The Russian has secured points finishes in four of the seven races so far this year.
Kvyat's F1 career looked to be finished when he was dumped by Toro Rosso before the end of the 2017 season, having been demoted from Red Bull the year prior.
He was praised for his work with Ferrari last year, which included passing on advice on set-up ahead of races in the simulator.
Now back in full-time racing, Tost says the new Kvyat is an impressive competitor.
"Daniil is much more experienced now," Tost said. "He is much more mature.
"He understands the technical side much better. Last year, as well all know, he was working at Ferrari in the simulator.
"I think that he learned there also a lot and everything is coming together with him and therefore he is showing a good performance."
Kvyat's rookie team-mate Alexander Albon has also done well, scoring in Bahrain, China and Monaco.
Albon had not driven a Formula 1 car before pre-season testing this year, but Tost says the Thai driver's natural speed has been undimmed.
He added: "I must say that Alex is coming up with a very good performance and I think he is a surprise. He is making good progress.
"We have two real competitive drivers. They have high natural speeds; they are quite good, talented."
