Mercedes competed in the 2026 Miami Grand Prix with the same W17 spec they started the season with while rivals brought major upgrades.

While McLaren, Ferrari, and Red Bull Racing had comprehensive upgrades on their respective cars in Miami, Mercedes opted to wait till Canada to bring the first upgrade package for their dominant W17.

While Ferrari flattered to deceive, McLaren managed to close the gap in Miami to Mercedes, who seemed to have enough in reserve to take the win of the Grand Prix with Kimi Antonelli, while reigning Formula 1 Champion Lando Norris won the Sprint Race.

But now Mercedes are looking to hit back with their first major upgrade package for the W17.

Previewing the race in Montreal this weekend, Mercedes boss Toto Wolff said: "We head to Canada ready to get back into a regular rhythm of racing.

"Our competitors took a step forward in Miami, and we need to respond; seven Grands Prix in 10 weekends before shutdown is an opportunity to do that and build momentum.

"We bring our first update package of the year to Montréal, but we know that performance is only performance once it is delivered on track.

"Despite being in the middle of May, we are just four races into the season," the Austrian went on. "There is a long year ahead, and, whilst this is an important weekend, it will not decide any outcomes. We will stay balanced, keep learning, and execute each weekend as well as we can.

"We won't get too high when we succeed or too low in the difficult moments; that is as true for our drivers as it is for the rest of the team," Wolff concluded.

Mercedes lead the 2026 F1 Constructors' Championship, 70 points clear of Ferrari in second place.

Antonelli and George Russell are one and two in the F1 Drivers' Championship, respectively, the Italian 20 points ahead of the Briton.
