Revealed: 2026 Formula 1 Car Renderings and Major Regulation Changes Detailed by FIA

The FIA has recently introduced the regulations for the upcoming 2026 Formula 1 season, revealing new car designs in the process. The changes for 2026 include a reduction in size and weight, with the wheelbase decreasing by 200 mm to 3,400 mm, width down by 100 mm to 1,900 mm, and weight lowered by 66 lbs to 1,693 lbs. Pirelli tires will also be smaller, with front width reduced by 25 mm, and rear width by 30 mm, while the 18-inch wheels introduced in 2022 will remain.

Significant alterations in aero are on the horizon, allowing teams to incorporate active aerodynamics for both the front and rear wings. The FIA is permitting a two-element flap for the front wing and three elements for the rear, enabling manual activation by the driver. Of note, active aero can be deployed regardless of the gap to the car ahead, but only in designated safe zones on the track lasting longer than three seconds. These changes are aimed at reducing drag and downforce by 55% and 30%, respectively, leading to closer racing.

The powertrains are set to undergo transformations as well, with the 1.6-liter turbocharged V6 engines running on 100% sustainable fuel now generating approximately 536 horsepower, down from 738 horsepower. To compensate for this decrease, the 2026 cars will feature more electric power, aiming for a 50-50 split between combustion and electric. With an anticipated 470 horsepower from the battery-electric element, the cars are expected to be faster, providing around 120 horsepower more than current models.

Increased reliance on electric power will see enhanced energy harvesting from braking, with teams projected to harvest about 8.5 megajoules per lap. Drivers can now utilize an “MGU-K Override” switch to deploy additional power for overtaking, aiding in high-speed maneuvers. Safety features have also been improved for 2026, including a new two-stage nose design, enhanced side intrusion protection, and better fuel cell protection. Additionally, safety lights will indicate the status of a car’s energy recovery system for the safety of drivers and marshals, while increased roll hoop loads have been implemented without adding extra weight.
