Carlos Sainz believes that running with inferior power units has allowed him to grow stronger as a driver.
In his maiden Formula One season, Toro Rosso ran hampered Renault power units which did not deliver as much as Ferrari and Mercedes. In 2016, Toro Rosso are running 2015 Ferrari units which doesn't allow any progress to be made on them.
However, Sainz thinks that his performances have benefited from not having as much power as his competitors.
“I have done two seasons now with the least top speed of the whole grid and I must say it has made me stronger,” said Sainz. “[Compared to] the beginning of last year, I’m not the same driver at the races.
“I have learned how to manage many things in the race and I think my results lately prove it. I’m able to extract that tiny bit more that maybe I was not expecting to extract.
“This situation has made me a stronger driver and a more consistent driver in the races. You are allowed to do less mistakes and you have to make sure that when you do get the chance to overtake, you make it stick.
“It can be the one and only chance in the whole race to overtake a Renault, when you do your stop and they are on old tyres – even if you don’t have top speed, you have to make it work.
“It’s these kinds of situations that I’m sure are making me stronger and more experienced and helping me go forward.”
