If you are a new player who enters the world of online betting, you should know that there are a lot of terms to learn.
107% rule in F1 Glossary & Terms
During the first phase of qualifying, any driver who fails to set a lap within 107 percent of the fastest Q1 time will not be allowed to start the race. However, in exceptional circumstances, which could include a driver setting a suitable time during practice, the stewards may permit the car to start.
The study of airflow over and around an object and an intrinsic part of Formula One car design.
The engine air intake above the driver’s head, which also serves as the car’s roll hoop.
The middle point of the inside line around a corner at which drivers aim their cars.
An action that a team takes on its drivers’ behalf if it feels that they have been unfairly penalised by the race officials.
A device that uses heat and pressure to ‘cure’ carbon fibre, the primary material Formula One cars are made of.
A term used to describe a driver at the rear end of the field, often when he is encountered by the race leaders. Blue flags are used to inform the backmarker when he should let a faster car past.
Weights fixed around the car to maximise its balance and bring it up to the minimum weight limit.
The piece of bodywork mounted vertically between the front wheels and the start of the sidepods to help smooth the airflow around the sides of the car.
The consequence of a tyre, or part of a tyre, overheating. Excess heat can cause rubber to soften and break away in chunks from the body of the tyre. Blistering can be caused by the selection of an inappropriate tyre compound (for example, one that is too soft for circuit conditions), too high tyre pressure, or an improperly set up car.
The carbon fibre sections fitted onto the monocoque before the cars leave the pits, such as the engine cover, the cockpit top and the nosecone.
Bottoming in F1 Glossary & Terms
When a car’s chassis hits the track surface as it runs through a sharp compression and reaches the bottom of its suspension travel.
A switch in the cockpit to alter the split of the car’s braking power between the front and the rear wheels according to a driver’s wishes.
Short for Computer-aided design, the method used to design Formula One cars.
The angle at which a tyre leans into or away from the car relative to the vertical axis. Engineers will vary camber to improve a car’s handling characteristics.
Short for Computational fluid dynamics, a tool used by F1 designers that uses complex mathematics and simulation to predict aerodynamic airflow. Normally used in conjunction with traditional wind tunnel research.
Chassis in F1 Glossary & Terms
The main part of a racing car to which the engine and suspension are attached is called the chassis.
A tight sequence of corners in alternate directions. Usually inserted into a circuit to slow the cars, often just before what had been a high-speed corner.
Air that isn’t turbulent, and thus offers optimum aerodynamic conditions, as experienced by a car at the head of the field.
The tendency of a fluid jet, such as airflow, to be attracted to a nearby surface. F1 aerodynamicists use the effect to help divert airflow to specific areas of the car, for example from the exhaust exit to the rear diffuser.
The section of the chassis in which the driver sits.
Tread compound is the part of any tyre in contact with the road and therefore one of the major factors in deciding tyre performance. The ideal compound is one with maximum grip but which still maintains durability and heat resistance. A typical Formula One race compound will have more than ten ingredients such as rubbers, polymers, sulphur, carbon black, oil and other curatives. Each of these includes a vast number of derivatives any of which can be used to a greater or lesser degree. Very small changes to the mix can change compound performance.
The meeting between a team’s drivers and engineers after an on-track session in which car set-up, performance and strategy are discussed.
Degradation in F1 Glossary & Terms
A term used to describe the process by which a tyre loses performance or grip. Different from tyre wear which concerns the process by which the tread is worn away.
A term used to describe the time difference between two different laps or two different cars. For example, there is usually a negative delta between a driver’s best practice lap time and his best qualifying lap time because he uses a low fuel load and new tyres.
The rear section of the car’s floor or undertray where the air flowing under the car exits. The design of the diffuser is crucial as it controls the speed at which the air exits. The faster its exit, the lower the air pressure beneath the car, and hence the more downforce the car generates.
The aerodynamic force that is applied in a downwards direction as a car travels forwards. This is harnessed to improve a car’s traction and its handling through corners.
The aerodynamic resistance experienced as a car travels forwards.
One of two penalties that can be handed out at the discretion of the Stewards whilst the race is still running. Drivers must enter the pit lane, drive through it complying with the speed limit, and re-join the race without stopping.
Drivers’ briefing in F1 Glossary & Terms
A meeting of all the drivers and the FIA race director to discuss issues relating to that particular Grand Prix and circuit. Other subjects, such as driving standards and safety, may also be discussed.
Also known as adjustable rear wings, DRS (Drag Reduction System) rear wings allow the driver to adjust the wing between two pre-determined settings from the cockpit. The system’s availability is electronically governed – it can be used at any time in practice and qualifying (unless a driver is on wet-weather tyres), but during the race can only be activated when a driver is less than one second behind another car at pre-determined points on the track. The system is then deactivated once the driver brakes. In combination with KERS, it is designed to boost overtaking. Also like KERS, it isn’t compulsory.
Short for Electronic Control Unit, a standard unit that controls the electrical systems on all F1 cars including the engine and gearbox.
Endplate in F1 Glossary & Terms
The vertical panels that form the outer edges of a car’s front and rear wings and to which the main wing elements are attached.
The Energy Store (sometimes abbreviated to ES) is an integral part of an F1 car’s powertrain and ERS. Located in the fuel cell and weighing between 20-25kg, the Energy Store usually consists of lithium ion batteries. The Energy Store can store (or return to the drivetrain) 4MJ of energy per lap, although MGU-K (see ERS) may only charge the Energy Store with 2MJ per lap.
Energy Recovery Systems, or ERS for short, consist of Motor Generator Units that harness waste heat energy (from the turbocharger) and waste kinetic energy (from the braking system). This energy is then stored and subsequently used to propel the car. An F1 car has two ERS: MGU-K (which stands for Motor Generator Unit – Kinetic) and MGU-H (which stands for Motor Generator Unit – Heat). These systems are complemented by an Energy Store (ES) and control electronics. ERS is capable of providing 120kw of power (approximately 160bhp) for approximately 33 seconds per lap.
Flat spot in F1 Glossary & Terms
The term given to the area of a tyre that is worn heavily on one spot after a moment of extreme braking or in the course of a spin. This ruins its handling, often causing severe vibration, and may force a driver to pit for a replacement set of tyres.
The lap before the start of the race when the cars are driven round from the grid to form up on the grid again for the start of the race. Sometimes referred to as the warm-up lap or parade lap.
A physical force equivalent to one unit of gravity that is multiplied during rapid changes of direction or velocity. Drivers experience severe G-forces as they corner, accelerate and brake.
When a car slides, it can cause little bits or rubber (‘grains’) to break away from the tyre’s grooves. These then stick to the tread of the tyre, effectively separating the tyre from the track surface very slightly. For the driver, the effect is like driving on ball bearings. Careful driving can clear the graining within a few laps, but will obviously have an effect on the driver’s pace. Driving style, track conditions, car set-up, fuel load and the tyre itself all play a role in graining. In essence, the more the tyre moves about on the track surface (ie slides), the more likely graining is.
A bed of gravel on the outside of corners designed with the aim of bringing cars that fall off the circuit to a halt.
Grip in F1 Glossary & Terms
The amount of traction a car has at any given point, affecting how easy it is for the driver to keep control through corners.
A term used to describe a car’s responsiveness to driver input and its ability to negotiate corners effectively. A car that handles well will typically be well-balanced and not understeer or oversteer to any great degree.
Short for Head and Neck Support Device, a mandatory safety device that fits over the driver’s shoulders and connects to the back of the helmet to prevent excessive head and neck movement in the event of an accident.
The removable energy-absorbing foam that surrounds the driver’s helmet in the cockpit. Three different grades of foam are used, depending on the ambient temperature.
A term used to describe the process by which a tyre is heated through use and then cooled down. This has the effect of slightly changing the properties of the compound and can improve durability.
A lap done on arrival at a circuit, testing functions such as throttle, brakes and steering before heading back to the pits without crossing the finish line.
Jump start in F1 Glossary & Terms
When a driver moves off his grid position before the five red lights have been switched off to signal the start. Sensors detect premature movement and a jump start earns a driver a penalty.
A synthetic fibre that is combined with epoxy resin to create a strong, lightweight composite used in F1 car construction.
A style of braking made popular in the 1990s following the arrival of hand clutches so that drivers could keep their right foot on the throttle and dedicate their left to braking.
The term used to describe a driver braking sharply and ‘locking’ one or more tyres whilst the others continue rotating. Tyre smoke and flat spots are common side effects.
The sign on a stick held in front of the car during a pit stop to inform the driver to apply the brakes and then to engage first gear prior to the car being lowered from its jacks.
Marbles in F1 Glossary & Terms
The small pieces of tyre rubber that accumulate at the side of the track off the racing line. Typically these are very slippery when driven on.
A course official who oversees the safe running of the race. Marshals have several roles to fill, including observing the spectators to ensure they do not endanger themselves or the competitors, acting as fire wardens, helping to remove stranded cars/drivers from the track and using waving flags to signal the condition of the track to drivers.
The single-piece tub in which the cockpit is located, with the engine fixed behind it and the front suspension on either side at the front.
An artificial, fire-resistant fibre used to make drivers’ race overalls, underwear, gloves and boots.
The second – and usually softer – of the two tyre compounds nominated by the official tyre supplier for use at each Grand Prix. Not expected in theory to be as well suited as the prime tyre to that particular circuit’s characteristics, but may provide certain advantages in terms of pace or durability.
Out brake in F1 Glossary & Terms
A term used to describe a driver braking either too late or too softly and subsequently overrunning a corner. A common mistake made during overtaking moves.
When a car’s rear end doesn’t want to go around a corner and tries to overtake the front end as the driver turns in towards the apex. This often requires opposite-lock to correct, whereby the driver turns the front wheels into the skid.
Levers on either side of the back of a steering wheel with which a driver changes up and down the gearbox.
An enclosed area behind the pits in which the teams keep their transporters and motor homes. There is no admission to the public.
A fenced-off area into which cars are driven after qualifying and the race, where no team members are allowed to touch them except under the strict supervision of race stewards.
A board held out on the pit wall to inform a driver of his race position, the time interval to the car ahead or the one behind, plus the number of laps of the race remaining.
Where the team owner, managers and engineers spend the race, usually under an awning to keep sun and rain off their monitors.
An area of track separated from the start/finish straight by a wall, where the cars are brought for new tyres and fuel during the race, or for set-up changes in practice, each stopping at their respective pit garages.
A hard wooden strip (also known as a skid block) that is fitted front-to-back down the middle of the underside of all cars to check that they are not being run too close to the track surface, something that is apparent if the wood is excessively worn.
Pole position in F1 Glossary & Terms
The first place on the starting grid, as awarded to the driver who recorded the fastest lap time in qualifying.
The term used to describe the entire system providing an F1 car’s power. The powertrain (or power unit as it is sometimes known) comprises of the engine, two Energy Recovery Systems (ERS) and an Energy Store.
The periods on Friday and on Saturday morning at a Grand Prix meeting when the drivers are out on the track working on the set-up of their cars in preparation for qualifying and the race.
Of the two tyre compounds nominated by the official tyre supplier for use at each Grand Prix, the prime is the compound that is in theory best suited to that particular circuit’s characteristics. Normally harder than the option tyre.
An action lodged by a team when it considers that another team or competitor has transgressed the rules.
The knock-out session on Saturday in which the drivers compete to set the best time they can in order to determine the starting grid for the race.
Short for Research and Development, the term describes activities undertaken by a team to develop or improve a system or component.
Reconnaissance lap in F1 Glossary & Terms
A lap completed when drivers leave the pits to assemble on the grid for the start. If a driver decides to do several, they must divert through the pit lane as the grid will be crowded with team personnel.
When a car has to drop out of the race because of an accident or mechanical failure.
The height between the track’s surface and the floor of the car.
A bumpy, often saw-toothed strip of kerbing usually found on the exit of a corner to warn the driver of the edge of the track.
The course vehicle that is called from the pits to run in front of the leading car in the race in the event of a problem that requires the cars to be slowed.
The technical checking of cars by the officials to ensure that none are outside the regulations.
For timing purposes the lap is split into three sections, each of which is roughly a third of the lap. These sections are officially known as Sector 1, Sector 2 and Sector 3.
A brief test when a team is trying a different car part for the first time before going back out to drive at 100 percent to set a fast time.
The part of the car that flanks the sides of the monocoque alongside the driver and runs back to the rear wing, housing the radiators.
Slipstreaming in F1 Glossary & Terms
A driving tactic when a driver is able to catch the car ahead and duck in behind its rear wing to benefit from a reduction in drag over its body and hopefully be able to achieve a superior maximum speed to slingshot past before the next corner.
One of three high-ranking officials at each Grand Prix appointed to make decisions.
A penalty given that involves the driver calling at his pit and stopping for 10 seconds – with no refuelling or tyre-changing allowed.
See-through plastic strips that drivers fit to their helmet’s visor before the start of the race and then remove as they become dirty.
A system that beams data related to the engine and chassis to computers in the pit garage so that engineers can monitor that car’s behaviour.
Literally, the turning or twisting force of an engine, torque is generally used as a measure of an engine’s flexibility. An engine may be very powerful, but if it has little torque then that power may only be available over a limited rev range, making it of limited use to the driver. An engine with more torque – even if it has less power – may actually prove quicker on many tracks, as the power is available over a far wider rev range and hence more accessible. Good torque is particularly vital on circuits with a number of mid- to slow-speed turns, where acceleration out of the corners is essential to a good lap time.
The degree to which a car is able to transfer its power onto the track surface for forward progress.
Traction control in F1 Glossary & Terms
A computerised system that detects if either of a car’s driven (rear) wheels is losing traction – ie spinning – and transfers more drive to the wheel with more traction, thus using its more power efficiently. Outlawed from the 2008 season onwards.
Another name for the chassis or monocoque, so called because of its shape.
The result of the disruption of airflow caused by an interruption to its passage, such as when it hits a rear wing and its horizontal flow is spoiled.
Attached to the engine, a turbocharger uses an exhaust driven turbine to drive a compressor to increase the density of the intake air consumed by the engine. Denser air helps an engine create more power for its size. The residual heat energy contained in the exhaust gases after expansion in the cylinders of the engine is converted to mechanical shaft power by the exhaust turbine. The mechanical power from the turbine is used to drive not only the compressor, but also the MGU-H (see ERS).
The type of rubber mix used in the construction of a tyre, ranging from soft through medium to hard, with each offering a different performance and wear characteristic.
An electric blanket that is wrapped around the tyres before they are fitted to the car so that they will start closer to their optimum operating temperature.
Understeer in F1 Glossary & Terms
Where the front end of the car doesn’t want to turn into a corner and slides wide as the driver tries to turn in towards the apex.
A separate floor to the car that is bolted onto the underside of the monocoque.
The strip of carbon fibre-reinforced Zylon that is fitted to the top edge of a driver’s helmet for added protection.
The distance between the centre points of the front and rear wheels. An F1 car’s wheelbase influences the way it handles.
A term used to describe the movement of an F1 car around an imaginary vertical axis through the centre of the car. Often talked about in conjunction with pitch (movement around an imaginary horizontal axis across the centre of the car) and roll (movement through an imaginary longitudinal axis along the car’s centreline).
Zylon in F1 Glossary & Terms
A synthetic material often found in bulletproof vests which has strong anti-penetration properties and is used to strengthen drivers’ helmets and the sides of the cockpit.
