Montoya: Mercedes W17 was 'seconds' off true pace in Barcelona tests

Former F1 driver Juan Pablo Montoya has claimed Mercedes was running its new W17 car three to four seconds per lap slower than its full potential during pre-season testing in Barcelona, suggesting the team is hiding significant performance. Team principal Toto Wolff, while encouraged by early data, remains cautious, stating the true competitive picture won't be clear until rivals like Max Verstappen show their hands.

Why it matters:

If Montoya's insider information is accurate, it signals that Mercedes may have made a dramatic leap with its 2026 car, potentially vaulting it back into championship contention after several difficult seasons. This kind of strategic sandbagging in testing would reshape expectations for the upcoming season and put pressure on rivals Red Bull and Ferrari, who appeared strong in Barcelona.

The details:

• The Claim: On his MontoyAS podcast, Montoya stated, "From what I’ve heard, the lap times being set in Barcelona were still three to four seconds away from the car’s full potential."
• The Test Results: While Lewis Hamilton set the fastest time late in the test, the overall focus for Mercedes was on reliability. The team completed a robust 500 laps over three days with George Russell and rookie Kimi Antonelli, showing promising signs from the new power unit.
• Wolff's Caution: Despite positive early feelings, Toto Wolff told media, including GPblog, that it's too early for optimism. He emphasized that without seeing Verstappen, McLaren, or Ferrari push their cars, the true pecking order remains unknown: "We simply don’t know."
• The Ripple Effect: Montoya noted that if the Mercedes power unit is indeed a major step forward, all customer teams (like McLaren and Williams) should also show strong form, making it easier to identify which chassis are truly competitive.

What's next:

All eyes will be on the official pre-season test and the season opener to see if Mercedes unleashes the performance Montoya hints is in reserve. Verstappen's first competitive lap times will be the benchmark Wolff is waiting for, finally revealing whether the W17's potential is a rumor or reality and setting the tone for the 2026 championship fight.
