The pace of the W09 was encouraging at Paul Ricard, in part thanks to the introduction of the new engine specification and numerous small updates to the car.
While it wasn't the perfect Sunday in France for the team, it was great to return to the top step of the podium and leave the circuit in the lead of both Championships.
"I think what you saw in Montreal compared to Le Castellet is that marginal gains matter," Toto explained.
"We fell back in Montreal because we couldn't bring the new Power Unit. We were racing the first Power Unit for the seventh consecutive race while the others had upgrades, so that certainly didn't help.
"We're also constantly learning how to set the car up in the right way in combination with the tyres. And, of course, we brought some upgrades for the car which was good to see coming together.
"Thank you to everybody in the team who worked so hard to bring them to the track this weekend. All these gains in the respective areas added to a solid step which we could realise in just a few days in Le Castellet."
