Understeer and Oversteer
Before we go into whatâs what Iâm painting you a (not that realistic) picture Itâs qualifying and this car below is destined to be on pole. But before that they need to make that final corner that is coming up. Now there are 3 things that could happen: 1. they make the corner and start on pole, 2. he has understeer, 3. he has oversteer. Letâs zoom in on point 2 and 3 in the next slide.
Oversteer - When the back of the car snaps outside of the line of the car, kind of like drifting. The driver finds this easy to control, but this can cause a spin as the back âslidesâ to the side. A thing for our driver here to remember is: When they canât make the corner due to oversteer their ass is in the wall.
Understeer - When the front of the car doesnât want to turn into the corner, resulting in getting off the racing line/road. A thing for our driver here to remember is: When they canât make the corner due to understeer their face is off the track or in the wall.
Walter RĂśhrl has a quote on this: âOversteer in a normal car is when the passenger is afraid, understeer is when the driver is afraid. If you can see the thing youâre gonna hit, youâve got understeer. If you can only hear the crash, youâve got oversteer.â
Parc FermĂŠ & Apex
Parc FermĂŠ is basically the car park for F1 cars. Cars are parked there after qualifying to make sure teams donât work on the cars overnight. Itâs a rule in F1 that you race with the EXACT same car as you qualified with and Parc FermĂŠ locks the cars up to prevent the breaking of that rule.
Apex is the part of a corner drivers want to âhitâ in order to make their lap as smooth as butter. Our little driver (we need a name!) is back. If he follows the red line heâll hit the apex (the red dot) in the middle of the corner and then runs wide to join the outside part of the track again. A reminder then would be: From the outside of the track (before the corner) -> to the inside of the track (mid corner) -> to the outside of the track (after the corner).
ERS
F1 cars are âhybridâ cars - using both fuel and energy. ERS means the Energy Recovery System and as the name says - it helps to recover energy that could get lost in breaking or with waste heat. The MGU-K and MGU-H are part of the ERS. And I know this probably sounds difficult but letâs take it step by step. MGU stands for Motor Generator Units. The MGU has 2 roles to play in an F1 car: 1. MGU-K (K = Kinetic) - This part helps to recover and harness energy from the braking system. Every time a car breaks energy gets lost and the MGU-K prevents it and gives the car more power. 2. MGU-H (H = Heat) - This part helps to recover and harness energy from the waste of the car that is released through the exhaust pipe. The heat of this waste is then turned into more power to use while driving on track. All the harvest from the MGU-K and MGU-H goes into the Energy Store (ES), which the driver then can use to torpedo their car forward - going faster.
Downforce
Weâve all heard that F1 cars could in theory drive upside down in a tunnel and the reason for that is downforce! You can compare downforce to a magnet. As the car moves forward (like the old Ferrari down here would) the aerodynamics push the car firmly down on the track, sucking it to the asphalt. The downforce then helps the car move through corners and helps traction (which makes the car sturdy and fast).
DRS - Drag Reduction System
At certain points on a circuit drivers can use âDRSâ, a system the FIA brought in to make the cars slightly more compatible and make them go slightly quicker. But why do they have these and what does it do? Letâs start with the basics. Every F1 car has aerodynamic parts, parts that manipulate airflow around the car. Air causes friction and makes the car slower. So F1 cars have all these bits that help move the airflow to the sides so the car isnât held back by the air (Iâll explain this segment globally in Part 3 of the PPT). Pictured below youâll see the airflow when DRS is closed - The blue lines stand for the air around a car (donât judge, I know itâs ugly haha):
When the rear wing is closed the air âhitsâ it and gets pushed up. But still that initial hit of air makes the car slower. F1 cars are very sensitive to air, drag and just pressures from the outside. When they get into the DRS segment of the track, the rear wing opens meaning that the air doesnât hit anything anymore and making the car faster. The airflow is now not blocked and moves through the car flawlessly. In a race DRS can only be used when the driver behind is within 1 second of the person in front. They open the rear wing, giving them more speed so that they are able to fight the car in front better and faster.
No DRS, air hits the rear wing.
DRS activated, air flows through the rear wing.

Blistering & Marbles
Picture this - Our little friendly driver (still in need of a name) has been driving around the track on C4 tyres for about 15 laps. With every lap his tyre degraded a bit, because asphalt is not smooth. When a tyre keeps heating up and eventually overheats. - the rubber starts to soften and break off. This caused spots or lines on the tires that make the tyres weaker and weaker with every lap. If a blister becomes really bad the tyre could explode. Blistering could occur when using a bad compound on the track, the tyre pressure is too high or the car isnât set up well.
The part of the tyre that degrades each lap flings of the tyres onto the circuit which then is called marbles! You could say that marbles are little pieces of the rubber from the tyres that ends up on the circuit. They are extremely slippery so during a race you should avoid them at all costs! After a race, when the cars slow down, they often drive over the marbles to âstick them back onâ - to make the car a bit heavier when they are weighted.

VSC - Virtual Safety Car
I can see why this causes confusion. We have a safety car on track when an accident happens, but why is there a Virtual Safety Car? The rule is pretty simple: âWhen there is something on track that can be resolved in a matter of minutes (a piece of debris or something thrown on track) the VSC is deployed. Drivers have to slow down (to 30% of the speed they normally have), but the gaps in between them stay. The field doesnât get bunched up like it would with a Safety Car. But in reality this does happen because if youâre in a faster part of the circuit you can go faster and could slim down the gap to person in front who was in the slower part of the circuit. Think of it this way: With a real safety car the pace is determined by the safety car, the drivers drive around in a little train. With the virtual safety car the drivers have to constantly be aware of their speed and determine their pace for themselves.
Chassis & Sausage Kerbs
The chassis is difficult to explain but I found a good quote that will help us: âIf the engine is the heart of the car, the chassis is the spine.â. The chassis is the strongest part of the car (it has to be) and forms the frame of said car. Every part of an F1 car is bolted or attached to the chassis - for example the engine and suspension (the parts that connect the wheels to the car) are attached to it. It forms the bottom of the car, the base of the car and without you wouldnât have a car.
On a racetrack we need something to stop drivers for seeking the absolute limits of the track - sausage kerbs. They look like little yellow ramps and can be placed vertical to the track or horizontal. They are higher than the actual red and white kerbs that lay on the track in all the corners/braking zones.

Chicane & Box
The chicane is basically a corner to slow the drivers down and is often found at the end of a straight - which makes it the perfect place to get past the driver you are battling. In F1 itâs often in the shape of an S with a quick left to right. They are tight, quick corners but unforgiving. One of the most famous ones is the âSingapore Slingâ which sadly isnât with us anymore. As far as my knowledge goes every track has at least one chicane or something to resemble it.
Picture this - Our little friendly driver (that needs a name) kept driving with those C4 tyres for now a total of 20 laps and they desperately need them changed. Their race engineer will then call âBOX BOXâ through the radio to signal for the driver to come into the pits. Box basically means coming in for new tyres (or something else pit related) and is a word that is easier to get while drivers are going around the track. It has a distinctive sound and pit could for example be confused with fit, while box really doesnât have a word that could resemble it!
