F1 Explains: Race Engineers - with Haas F1 Team's Laura Müller

In Formula One, the race engineer is the key engineer who communicates with the driver during a race. They translate car and track data into instructions—like setup changes and strategy calls—so the driver can adapt in real time.

In racing, the cockpit refers to the driver’s enclosed seating area inside the car. It’s where the driver controls the car and receives communications during a race.

The “new era” of Formula One refers to a period of rule and technical changes that affect how teams design cars and run races. Those changes can make communication and race engineering more complex because the car’s behavior and strategy constraints shift.

“Regs” is short for regulations. In Formula 1, new technical regulations can change how cars are designed and how race engineers set up and manage the car.

MG UK refers to the “Motor Generator unit – Kinetic” used in F1’s hybrid system. It can both generate electricity during braking (harvesting energy) and provide electric torque to help accelerate.

An electrical motor is an electric machine that produces rotational power using electricity. In modern F1 hybrid power units, electric motors work alongside the combustion engine to provide extra propulsion and energy recovery.

In F1, the motor-generator unit (MGU) can harvest energy from the car’s motion. The “kinetic” part refers to recovering energy during braking and other deceleration phases, then using it later to add power.

Horsepower is a measure of engine power output. In this context, the MGU’s recovered energy must be sufficient to deliver more of the car’s overall power, so energy management becomes a key performance limiter.

Energy management in modern F1 is about deciding when to harvest energy and when to deploy it for acceleration. Because the car can only recharge and use energy in certain places, the race engineer and driver must optimize the lap around those constraints rather than just chasing peak speed.

“Recharging” refers to the process of storing energy back into the hybrid system during specific driving phases. In F1, it’s constrained by braking and traction events, so where and when you can recharge directly affects how much power you have later.

In F1 energy terms, “deploy” means using stored hybrid energy to add power at the wheels. The driver and race engineer coordinate deployment timing so the car is fast where it matters without wasting energy that could be used later.

Here, “efficiency” means getting the most performance out of limited energy and traction rather than simply maximizing raw speed. With hybrid constraints, small losses in how you manage energy and corner exits can cost more time than before.

In Formula 1, the car’s energy system has to be managed so the battery state is ready for the single fastest run (“hot lap”). Race engineers plan energy usage so the driver can deploy maximum performance when it matters most.

In this context, “launch” means the moment the car accelerates hard from the start of a qualifying run. Engineers focus on getting the timing and power delivery right so the driver can go full throttle without wasting limited energy early.

“Partial” refers to using less than maximum power during parts of the lap. Engineers use partial-throttle/partial-power phases to stay within energy deployment limits while still setting up the driver to hit full performance at the right moment.

In Formula 1, “car setup” is the set of adjustments engineers make to match the car to a specific driver and track. It typically covers things like suspension settings, aerodynamic balance, and tire pressures so the car behaves predictably in corners, braking, and on exit.

“Suspension setup” refers to the configuration of the suspension system—how the car’s springs, dampers, and geometry are adjusted. In F1, it strongly affects grip, tire wear, and how the car stays stable under braking, acceleration, and cornering.

“Ride hides” appears to be a transcription error for a suspension/ride-related term (commonly “ride heights” in F1). Ride height is the car’s ground clearance, and changing it affects aerodynamic performance and how the suspension works.

Downforce is the aerodynamic force that pushes the car toward the track. In F1, it’s generated mainly by wings and body aerodynamics, and it increases tire grip—especially in high-speed corners—at the cost of aerodynamic drag.

Mechanical loads are the forces the car structure and suspension experience from driving conditions—like cornering forces, braking forces, and impacts from the track. Engineers balance these with aerodynamic effects so the car stays stable and the tires operate in the right window. The segment frames it as part of balancing the car’s overall “loads.”

Tyre degradation is the gradual loss of tire performance as the tire heats up and wears during a stint. In F1, engineers must plan around how grip will drop over time, not just what the car feels like at the start. The guest highlights balancing tire degradation against other performance factors for the race outcome.

In F1, “data” refers to the live telemetry and sensor readings the team uses during a session to understand what the car is doing. Engineers interpret trends to diagnose issues and guide setup decisions. The guest describes using “squiggly lines” to see what’s happening on the car.

In Formula 1, the safety car is deployed when there’s danger on track (like debris or an accident). It controls the pace of the field by forcing everyone to drive slower, which changes the timing and “value” of pit stops.

“Time loss for a pit stop” is the amount of time a car spends slower than racing speed while entering, stopping, and exiting the pits. In F1, that loss is measured relative to the cars on track, and under safety car conditions the relative loss can shrink because the rest of the field is also slowed.

In F1, the “strategy guys” are the team members focused on race strategy—especially decisions around pit stops, tire timing, and how to respond to race events like safety cars. Their guidance heavily influences what the race engineer tells the driver in real time.

“Pit now” refers to the immediate decision to enter the pit lane for a pit stop, typically to change tires and/or make other adjustments. Timing matters because safety cars can reduce the time lost relative to staying out.
