"I think we need to go through the data to understand why we were so fast today, because we had small upgrades on the auto, but it seems to work much better than what we expected".
Gasly proved all of the doubters wrong and came of age as a Formula 1 driver during Sunday's Bahrain race, backing up his strong qualifying pace with fourth place on the day that counts and, in the process, scored Honda's best Grand Prix result since Rubens Barrichello finished third in the 2008 British Grand Prix.
Gasly was overhauled by Hamilton, but gained fourth back when Kimi Raikkonen was forced out, and from there cruised clear of the midfield pack to collect 12 points for Toro Rosso. "We saw that we had some good potential but to be P6 in qualifying is just unbelievable, so I'm really happy".
"Big thanks to the team because the auto was fantastic all weekend and today there was an opportunity and we had the vehicle to take this".
When asked when he'd taken extra pleasure from outqualifying each McLarens, then Gasly laughed: " I didn't even convey it to the radio, but yeah, to get certain.

The Toro Rosso team hoisted Gasly shoulder-high after he crossed the finish line behind Ferrari victor Sebastian Vettel and Mercedes pair Valtteri Bottas and Hamilton.
McLaren, who have precisely the same motors which power Red Bull, neglected to find both of these cars beyond the second phase of qualifying with Fernando Alonso 13th and also Stoffel Vandoorne 14th.
