Lift and Coast in Formula 1: what it is and why drivers do it

A Formula 1 driver lifts off the accelerator before the braking zone, lets the car slow down and only then hits the brake pedal. It might look like a small concession in a sport measured in thousandths of a second, but lift and coast can help a driver manage fuel, electrical energy and temperatures across a race.

The trade-off is immediate: lifting early costs time on the straight. The skill lies in choosing where and when that cost is smallest, while protecting the resources needed to attack, defend or simply reach the chequered flag.

What is lift and coast in F1?

On a flat-out lap, a driver generally stays on the accelerator until the braking point. With lift and coast, they release it earlier, travel for a short distance without applying the brakes, and then brake for the corner.

The car does not roll freely as if it were in neutral. Aerodynamic drag, resistance from the powertrain and, when selected, electrical energy recovery can all slow it. Because the car arrives at the braking zone at a lower speed, the driver must adjust the braking point and pressure to reach the corner correctly.

In a 2015 FIA press conference, Nico Hülkenberg explained that the challenge was not lifting itself but doing it efficiently, judging the changed braking point and losing as little lap time as possible.

Why does lifting save fuel?

When the driver comes off the throttle early, the engine spends less time delivering power on the straight. Repeating that across a race can reduce fuel consumption. With refuelling prohibited during a race, a driver who is using more fuel than planned may need to save some to reach the finish.

Fuel saving is not always a sign of a mistake. Starting with less fuel reduces the car's mass, which can improve lap time, but leaves less margin to run at maximum consumption throughout the race. Teams must balance the gain from a lighter car against the time spent saving fuel.

Lifting near the end of a straight makes strategic sense because the car already needs to slow for the next corner. At high speed, aerodynamic drag is substantial, so continuing to accelerate for the final part of the straight can use fuel for a relatively modest speed gain that must soon be shed under braking.

That does not make the technique free. The precise time cost depends on the circuit, the length of the lift, the car's settings and how well the driver executes the corner.

How does it recharge the battery?

Modern F1 cars have an MGU-K, an electrical motor-generator connected to the drivetrain. When harvesting, it resists rotation and converts some of the car's kinetic energy into electricity for the energy store. That electrical energy can later be deployed to help accelerate the car.

Lifting gives the team another opportunity to harvest before the driver reaches the brake pedal. But lifting does not automatically mean more total energy is recovered: the outcome depends on the selected settings, battery state and recovery available elsewhere, including under braking. Some energy is also lost to drag and other resistance rather than captured.

During braking, the MGU-K works alongside the friction brakes. Our guide to F1 brake-by-wire explains how the rear braking system manages that changing blend.

Why is lift and coast so important in 2026?

The 2026 power units place a much greater emphasis on electrical performance. The MGU-K can deliver up to 350kW, compared with 120kW under the preceding rules, making the timing of energy recovery and deployment central to lap time.

Drivers can recover energy under braking, on part throttle and when lifting. Another method, known as super clipping, allows the car to harvest while the driver remains at full throttle. Both can affect acceleration, but only lift and coast involves the driver deliberately releasing the accelerator before braking.

There is a further aerodynamic consequence: Formula 1's explanation of the 2026 system says lifting disables the active aerodynamic devices, while harvesting at full throttle can allow them to remain open. Teams therefore have to balance the cost of drag, recovery and deployment against one another.

The governing body has already adjusted energy-management parameters during the season. At Suzuka, the permitted qualifying recharge was reduced from 9MJ to 8MJ, a change intended to reduce the need for harvesting on straights and for lifting and coasting. Those figures describe that specific qualifying change, not a universal allowance for every session or circuit.

Can it help cool the car?

Yes. Approaching a corner at a lower speed can reduce the work required from the friction brakes, helping manage their temperatures and wear. Lifting can also reduce the demands on the power unit when cooling is a concern.

The result depends on the car and conditions. Saving the brakes is not the same as charging the battery: the balance between regenerative and friction braking matters, and brakes that become too cold can also perform poorly.

When is the best time to lift?

A driver with a comfortable gap may save resources while sacrificing little track position. In traffic, following a rival can also make outright pace less useful if there is no immediate opportunity to pass. But lifting too early with a rival close behind can leave the car vulnerable.

Teams must weigh that immediate risk against what the saved fuel, electrical energy or temperature margin could deliver later. A driver may spend time managing now to have more performance available for an attack, a defence or the final laps.

For the driver, the job is to make each lift repeatable without compromising the corner. For the team, it is to decide whether the time surrendered on that straight buys back more over the rest of the race.
