Leclerc's 'Very Impressive' F1 2026 Update Boosts Hamilton, Ferrari

Ferrari's 2026 F1 power unit development is reportedly making "very impressive" progress, according to Charles Leclerc, a significant boost for both the team and incoming driver Lewis Hamilton, who will not receive any further 2025 car upgrades as focus shifts to the new regulations.

Why it matters:

Ferrari, as both a chassis and engine manufacturer, is dedicating all resources to the upcoming 2026 regulations, which promise to reshape Formula 1. Leclerc's optimistic feedback on the new power unit's development suggests the Scuderia might be on the right track to become a major contender, crucial for Hamilton's championship aspirations after a challenging 2025 debut with the team.

The Details:

• Regulation Overhaul: The 2026 regulations introduce substantial changes, including 'nimble car' concepts with lighter (30kg reduction) and slightly smaller chassis.
• Aerodynamics: The Drag Reduction System (DRS) will be replaced by active aerodynamics on both front and rear wings.
• Tyres: Pirelli tires will become narrower, by 25mm at the front and 30mm at the rear.
• Power Unit Evolution: The internal combustion engine (ICE) will run on fully sustainable biofuel. Critically, electrical energy output will dramatically increase, with the MGU-K generating up to 350kW, a significant jump from the current 120kW.
• Leclerc's Optimism: Charles Leclerc, who previously expressed some concern about the 2026 rules, now reports "very impressive" weekly gains in development. He acknowledges the immense challenge but sees it as an opportunity.
• Hamilton's Perspective: Lewis Hamilton, set to join Ferrari in 2025, confirmed his current team's full focus on the 2026 car means no further upgrades for the 2025 chassis, making Leclerc's positive feedback on the future project even more critical for his championship hopes.

What's next:

Energy management will become a pivotal aspect of performance in 2026, given the massive increase in electrical power. Leclerc views this as an additional challenge beyond pure driving skill, emphasizing the need for early understanding and competitive advantage. The success of Ferrari's 2026 project will determine the team's fortunes and potentially provide Hamilton with a much-needed shot at redemption after a likely transitional 2025 season.
