A detailed comparison of F1 2025 and F1 2026 cars, covering regulation changes, car specifications, safety improvements, and performance expectations.
The 2026 Formula 1 season will bring significant regulation changes, marking one of the sport's most transformative eras. A new chassis, revamped power units, and updates to car size and weight aim to enhance performance, sustainability, and racing dynamics. Additionally, new entrants like Cadillac and power unit manufacturers Audi and Red Bull Ford Powertrains will join the grid.
What’s Changing Between F1 2025 and F1 2026 Cars?
The FIA has outlined numerous changes for F1 2026, targeting improved agility, sustainability, and competitiveness. Below are answers to key questions about these updates.
Will F1 2026 Cars Be Smaller or Larger?
The F1 2026 cars will be slightly smaller than their 2025 counterparts. The FIA aims to make the cars more nimble by reducing their size:
- F1 2025 Dimensions: Length: 3600mm, Width: 2000mm
- F1 2026 Dimensions: Length: 3400mm, Width: 1900mm
Will F1 2026 Cars Be Lighter?
Yes, the F1 2026 cars will weigh less. The minimum weight will drop from 800kg to 768kg, aligning with the FIA’s goal to make cars lighter and more responsive.
How Will Power Generation Change in F1 2026?
The 2026 power units will focus on efficiency and sustainability, using fully sustainable fuel and an increased reliance on electrical power. Key specifications include:
- Engine: 1.6-liter V6 turbo hybrid
- Fuel: 100% sustainable fuel
- Internal Combustion Engine (ICE) Power: Approx. 535bhp
- MGU-K Power: Approx. 470bhp
- Total Power: Over 1000bhp
- Fuel Limit: Approx. 70kg per race
Will F1 2026 Cars Be Faster or Slower?
F1 2026 cars are expected to be slower over a single lap due to reduced downforce and lower cornering speeds. However, improved straight-line speed and ongoing car development could narrow the gap as the season progresses.
Will F1 2026 Cars Sound Different?
The sound profile of F1 2026 cars remains uncertain. With the ICE configuration unchanged but contributing less to power output, and increased electric components, the cars may be quieter than their F1 2025 predecessors.
What Are Active Aerodynamics?
Active aerodynamics will replace the drag reduction system (DRS) in F1 2026. This system allows drivers to adjust both the front and rear wings, enhancing straight-line speed while reducing drag. Unlike DRS, all drivers can use this feature at specific points on the track.
Will Tires Change in F1 2026?
Tire sizes will slightly decrease, with Pirelli reducing the width of front tires by 25mm and rear tires by 30mm. This change will save approximately 5kg across a set of four tires, with minimal impact on grip.
Are F1 2026 Cars Safer?
Yes, the FIA has introduced several safety improvements for F1 2026, including:
- Enhanced front impact structures
- Doubled fuel cell protection
- Roll hoop load increase from 16G to 20G
- Lateral safety lights indicating ERS status
What Are the Goals of F1 2026 Changes?
The updates aim to promote closer racing, improve sustainability, and address concerns about the growing size of F1 cars. With active aerodynamics, sustainable fuel, and smaller, lighter cars, the FIA hopes to create an era of innovation and competitive balance while supporting environmental goals.
