It is a commonly used description to say that Formula 1 is the greatest engineering battleground. Races are not decided by the driver’s skill alone, but by thousands of small decisions that are made in the factory or wind tunnel months before the wheels roll onto the track. The crux of those decisions is one fundamental question: which part is the right part?
Science of choosing the right component in F1
Each season, F1 teams test hundreds of variations of components and choose among them what they fit in the car. The entire brake duct, suspension parts, gearbox internals and aerodynamic surfaces are tested and selected rigorously. As Aston Martin’s recent experience with their first in-house gearbox has shown, selecting the wrong specification or rushing an untested part into competition can have serious consequences — from lost race positions to genuine safety concerns.
All teams engage in a detailed car part comparison at each stage of development. Engineers make compromises with weight, durability, heat and drag. Thirty grams of lighter brake caliper components might save some money, but if the caliper does not stand up to the thermal stress on a street circuit such as Monaco, then that’s a cost. A bad decision affects the whole car and a bad weekend can be ruined by one bad decision.
How cost caps have changed part selection
The F1 cost cap of 2021 changed the approach of teams to their component selection. Pre-budgeting days, the top teams would just make and test all of the possibilities. These days, even the richest groups have to be shrewd. Forbes reports that the average F1 team now has a value of more than $2 billion, but they have tight budgets to stick to that makes for real prioritisation.
This is not a mere engineering feat, but one that is financial. Teams need to determine in what ways they will invest their limited budgets; whether they should make a major investment in an existing component or invest in a new one. The philosophy is pretty much the same as what a typical car owner would encounter when maintaining and upgrading his or her car, but at a much higher premium.
What road car owners can learn from F1 engineering
This approach to F1 part selection can be used in many aspects of life outside of the car. If you’ve ever had to replace a suspension arm, brake disc, or headlamps on your everyday car, you know the dilemma that an F1 engineer has to deal with: choosing the component that’s both reliable and compatible with your car and affordable.
Original manufacturer parts will ensure a perfect fit but may be more expensive. Only if you go with a reputable supplier, can aftermarket parts provide the same performance at a lower cost. This is just like in an F1 factory, only on the road — it takes research and information to make an informed choice.
Why informed decisions win on every level
It can be a team principal approving a new floor specification or an owner deciding between two suitable brake pads, the basic concept is the same. Knowledge is power; better information is better power. In F1, it’s based on data from the telemetry, simulation software and thousands of hours of testing. For road car owners, it’s from trusted comparison sites, reviewed by trusted sources, and easily accessible, clear product information.
Most people are unaware of the similarities that exist between motorsport engineering and everyday vehicle maintenance. Just like an F1 team, if they can save a tenth of a second on their lap timing, then you can save money and make the smartest choice the next time you need a car repair. The key is not to guess in either world, it’s to compare, assess and then play with conviction.
