Ferrari receives major SF-26 boost as Lewis Hamilton exposes key area of progress. SF-26 development takes positive turn as Lewis Hamilton delivers encouraging result for Ferrari.

Lewis Hamilton’s outstanding performance at the Canadian Grand Prix has provided Ferrari with fresh optimism that one of the SF-26’s most persistent weaknesses is finally moving in the right direction.

While much of the attention surrounding Ferrari’s 2026 Formula 1 campaign has focused on the power deficit of its engine compared to rival manufacturers, particularly Mercedes, the Maranello team has also been working intensively behind the scenes to address another critical limitation: thermal tyre degradation.

Throughout the opening phase of the season, Ferrari’s engineers have been forced to deal with a car capable of generating strong pace over a single lap but often vulnerable during longer race stints when tyre temperatures drifted outside the ideal operating window. That weakness frequently compromised race strategy and limited the ability of both Lewis Hamilton and Charles Leclerc to consistently challenge at the front.

However, recent evidence from Montreal suggests the situation may be improving significantly.

Canadian Grand Prix provides valuable evidence for Ferrari

Lewis Hamilton delivered his strongest result since joining Ferrari by securing second place at the Circuit Gilles-Villeneuve, a performance that not only rewarded the seven-time world champion but also offered valuable technical encouragement to the team.

Despite continuing to operate with a power unit that is generally considered less competitive than Mercedes’ benchmark engine, Lewis Hamilton was able to remain firmly in the fight at the front of the field throughout the race. Even more importantly for Ferrari, the SF-26 showed signs of much better tyre management than it had demonstrated during several earlier events.

According to reports from the Italian media, Ferrari engineers viewed the Canadian Grand Prix as a particularly important test because thermal degradation has remained one of the car’s most significant shortcomings since the start of the season.

During the opening races in Australia, China, Japan and Miami, Ferrari frequently struggled to keep tyre temperatures under control, especially during longer stints and in changing track conditions. Excessive overheating often caused performance to drop away rapidly, forcing the team into defensive race management.

In Montreal, however, the picture appeared noticeably different.

Lewis Hamilton recovered after early difficulties

The race was not entirely straightforward for Lewis Hamilton. Early in the Grand Prix, he faced strong pressure from Max Verstappen, who managed to overtake the Ferrari driver during the opening stages after launching an aggressive move into Turn 1.

Using the soft-compound Pirelli tyres, the Red Bull initially appeared to have a pace advantage, allowing Max Verstappen to establish a gap after the first phase of the race.

Even after both drivers switched to medium tyres, the Red Bull driver briefly extended his advantage, opening a lead of almost five seconds during the middle portion of the Grand Prix.

What impressed Ferrari most, however, was the way Lewis Hamilton managed his tyres through the most demanding stages of the race. Rather than suffering a prolonged decline in performance, the British driver experienced only a relatively short period where tyre temperatures became difficult to control before successfully bringing the compounds back into their optimal operating range.

That recovery proved decisive.

In the closing laps, Lewis Hamilton was able to significantly reduce the gap and launch a counterattack. With just a handful of laps remaining, he executed a decisive move around the outside of Max Verstappen at Turn 1, reclaiming second position and holding onto the place until the chequered flag.

For Ferrari’s technical department, that late-race resurgence may have been even more encouraging than the final result itself. The ability to restore tyre performance after a difficult phase is something the team struggled to achieve earlier in the season.

SF-26 chassis continues to earn praise

Inside Ferrari, there remains considerable confidence in the fundamental qualities of the SF-26 chassis. Team engineers have generally been satisfied with the aerodynamic platform and overall balance of the car, believing that its underlying potential is stronger than current championship standings might suggest.

The biggest limitation has largely been linked to the power unit package, which has prevented Ferrari from fully exploiting the strengths of the chassis on circuits where straight-line performance is particularly important.

This is why so much attention is currently focused on Ferrari’s expected eligibility for the FIA’s Additional Development and Upgrade Opportunities (ADUO) programme.

The system was introduced for 2026 to help manufacturers that fall behind in power unit performance reduce the gap to the benchmark engine supplier. Ferrari is widely expected to qualify for additional development allowances, potentially opening the door to important upgrades later in the season.

Should those improvements arrive as anticipated, Ferrari believes it could finally combine a more competitive engine package with a car that is gradually becoming more effective at managing tyre degradation.

Barcelona expected to provide clearer answers

Despite the positive signs from Canada, Ferrari remains cautious about drawing definitive conclusions.

Engineers are aware that the characteristics of the Monaco Grand Prix make it a poor reference point for evaluating tyre degradation. The Principality’s unique layout generates very low tyre wear compared to traditional circuits, meaning it will offer limited insight into whether the progress seen in Canada represents a genuine breakthrough.

As a result, Ferrari is expected to place particular emphasis on the upcoming Barcelona-Catalunya Grand Prix, where higher-energy corners and greater tyre stress should provide a much clearer picture of the SF-26’s true capabilities.

If the improvements observed in Montreal are confirmed in Spain, Ferrari could finally have evidence that one of its most troublesome performance limitations is being brought under control. Combined with the anticipated power unit developments, that would represent a major boost for both Lewis Hamilton and Charles Leclerc as Ferrari continues its pursuit of Mercedes at the front of the 2026 Formula 1 championship.
