The 2026 F1 season introduced a new power unit, new aerodynamics, and a new overtaking system simultaneously. This is the largest package of regulation changes since 2022. For a first-time race attendee or a fan returning after a few years away, the cars look different, sound different, and race differently from anything in the recent past. This guide explains the three changes that matter most from the grandstand.
Key facts
2026 cars use a new 1.6-litre turbocharged V6 hybrid power unit with a 50/50 split between internal combustion and electrical power. The MGU-H (motor generator unit - heat) is removed.
Active aerodynamics replace fixed bodywork on the front and rear wings. At defined speeds, the wings open to reduce drag on straights. This is called Super Clipping.
Manual Override Mode (MOM) replaces DRS as the overtaking system. MOM is a 350kW electrical power boost available to a following car within a set distance of the car ahead at specific detection points.
The removal of the MGU-H changes the exhaust sound. 2026 cars are louder in the mid-range frequency (audible as a more pronounced turbo screech and exhaust note) compared to 2022-2025 cars.
What has not changed: the same Pirelli tyre compounds, the same race weekend format (practice, qualifying, race), the same pit stop procedures.
The new power unit: what it sounds like from the stands
The MGU-H in 2014-2025 F1 cars was a motor generator that sat between the turbocharger and the engine. It harvested energy from the turbo shaft and used it to power the MGU-K (the primary electrical motor on the crankshaft). The MGU-H also helped spool the turbo faster, which reduced turbo lag.
Without the MGU-H, the 2026 engine has more turbo lag (the time between throttle application and full boost arrival) and the exhaust produces a different sound profile. At full power on a straight, the turbocharger note is more exposed. The characteristic quiet whine of the hybrid era is replaced by something closer to the older V8-era exhaust note, combined with the electrical motor.
From the grandstand, the most audible difference from 2022-2025 cars is at the exit of slow corners and on initial straight acceleration. The throttle application to full power takes slightly longer, and the sound transition from low load to high load is more gradual. Long-time F1 attendees will hear this as a change in the race's audio texture.
Active aerodynamics: what Super Clipping looks like
Active aerodynamics means the car's front and rear wing angles change during the lap. On straights above a defined speed threshold, the wings flatten out (reduce their angle of attack) to cut drag. As the car approaches a braking zone, the wings return to their high-downforce angle. This happens automatically.
Super Clipping is the name given to the effect where a car with active aero open on a straight has an advantage over a car with its aero closed (such as when the following car's aero is not triggered, or when two cars are at different speeds). The visual sign is a car that appears to accelerate unusually well in the straight-line section.
From the grandstand at the braking end of a long straight, you can see the aerodynamic effect as a difference in closing speed. A car running with its active aero open will close more rapidly on the car ahead. The Manual Override Mode deployment is layered on top of this: MOM adds electrical power as well as reduced drag.
Manual Override Mode is the overtaking system that replaced DRS in 2026. It works electrically, not aerodynamically. Understanding how it activates changes what you watch for when two cars are close on a straight.
Manual Override Mode ExplainedWhat has not changed
The race format is identical to previous years: three practice sessions (or two on a sprint weekend), qualifying, and the race. The race distance is determined by a time limit of two hours or a set number of laps. Sprint weekends (seven per season in 2026) include a sprint race on Saturday.
Pit stops, strategy, flags, and safety car procedures are unchanged. The tyre compound range (Pirelli C1-C5) is the same structure as previous years, though the 2026 compounds are reformulated for the new car weight and aero balance. Minimum two-compound requirement per race is unchanged.
The circuit calendar has 24 races in 2026. The basic grand prix weekend rhythm (arrive Friday, qualifying Saturday, race Sunday) is unchanged for non-sprint events.
The misconception: 2026 cars are not slower on circuits without DRS zones
The primary criticism of DRS in its final years was that overtakes were too easy: a car activating DRS on a long straight would simply drive past the car ahead without a real battle. Critics argued this undermined the strategy and driving skill elements that made F1 compelling before DRS was introduced in 2011.
MOM is designed to produce a more balanced power surge than DRS provided. A DRS-enabled car gained an aerodynamic advantage of approximately 0.5 to 0.7 seconds per lap. MOM is capped at 350kW additional power, which the FIA calibrated to produce a smaller advantage per activation. The goal is that a following car needs to be genuinely faster to complete the overtake, not simply deploy MOM and drive past.
The practical consequence from the grandstand: MOM overtakes are expected to require more driver skill than late-era DRS passes, but the strategic battles around MOM activation should be more visible and more contested than the DRS highway passes of 2018 to 2025.

Frequently asked questions
- What are the biggest changes in F1 2026?
- Three major changes: a new power unit without the MGU-H (motor generator unit - heat), active aerodynamics that change wing angles during the lap, and Manual Override Mode replacing DRS as the overtaking system. These changes affect the car's sound, its aerodynamic behaviour on straights, and the way overtaking battles unfold.
- Why do F1 2026 cars sound different?
- The removal of the MGU-H changes the exhaust and turbocharger sound profile. The MGU-H in 2014-2025 cars harvested energy from the turbo shaft and helped spool the turbo, which produced a distinctive whine. Without it, the turbocharger note is more prominent and the exhaust tone at throttle application has a different character. Most observers describe 2026 cars as louder in the mid-range frequency than recent-era cars.
- What is Super Clipping in F1 2026?
- Super Clipping is the visual effect produced by active aerodynamics on a straight. When a car's wings flatten to reduce drag above a speed threshold, the car accelerates faster in the straight-line phase. A car with its active aero open will close more rapidly on the car ahead than the same car with its aero in high-downforce mode. The term comes from the clipping of aerodynamic load that occurs in the straight phase.
- Is Manual Override Mode the same as DRS?
- No. DRS was a passive mechanical system: a rear wing flap opened to reduce drag. MOM is an active electrical system: it provides 350kW of additional power from the battery to the motor. MOM activates at specific detection points when the following car is within a set distance of the car ahead. The effect is a power boost rather than a drag reduction, which means the overtake requires the following car to be genuinely faster through the braking zone rather than simply better on top speed.
- How many races are on the F1 calendar in 2026?
- 24 races. Seven of these are sprint weekends with a short sprint race on Saturday in addition to the main race on Sunday. The sprint weekend format has a slightly different qualifying structure, with sprint qualifying separate from the main qualifying session.
- What is the 50/50 power split in F1 2026?
- F1 2026 power units produce roughly equal power from the internal combustion engine and from the electrical motor. In the 2014-2025 era, the split was approximately 80% combustion, 20% electrical. The 2026 target is 50% from each source. Total power output is estimated at around 1,000 horsepower, with the electrical component deployed continuously rather than in discrete bursts as in the previous era.
