Formula 1 cars might seem a world away from the performance cars we drive on the road, but the gap isn’t always as big as you’d think.
Motorsport has long been used as a testing ground for new ideas. When manufacturers are trying to find tenths of a second, improvements to braking, aerodynamics, transmissions and engine performance can make the difference between winning and finishing somewhere in the midfield.
Some of those ideas remain firmly within motorsport. Others eventually find their way into road cars.
Here are seven examples of motorsport technology that has helped shape the modern performance car.
1. Turbocharging
Turbochargers weren’t invented for motorsport, but racing played a major role in demonstrating just how much performance could be extracted from smaller-capacity turbocharged engines.
Formula 1 entered one of its most famous turbo eras during the 1980s, when manufacturers including Renault, BMW, Honda and Ferrari pushed increasingly powerful turbocharged engines to their limits.
Today, turbocharging is everywhere.
For Volkswagen and Audi enthusiasts in particular, engines such as the 2.0-litre TFSI and TSI have become synonymous with modern performance cars. Models including the Golf GTI, Golf R and Audi S3 demonstrate how much usable performance can now be produced from relatively compact engines.
Turbocharging has also helped create a huge tuning scene around these cars, with owners able to improve performance without replacing the entire engine.
2. Dual-Clutch Gearboxes
Fast gear changes are crucial in motorsport. Every fraction of a second spent changing gear is time when the car isn’t accelerating at its full potential.
That pursuit of quicker shifts helped accelerate the development of transmission technology that would eventually become available to ordinary drivers.
Dual-clutch transmissions use separate clutches for different sets of gears, allowing the next gear to be prepared before the shift takes place.
The result is incredibly quick gear changes.
Volkswagen Group’s DSG gearbox is one of the most recognisable road-going examples. What was once technology associated with high-performance machinery has become available across everything from everyday hatchbacks to cars such as the Golf GTI and Audi S3.
3. High-Performance Braking
Going faster is only useful if you can stop.
Braking technology is one of the areas where the relationship between motorsport and road-car performance is particularly easy to see.
Race cars need brakes capable of repeatedly slowing a vehicle from extremely high speeds without a dramatic loss of performance. That has encouraged the development of better brake materials, cooling methods and multi-piston calipers.
Carbon-carbon brakes remain largely the preserve of racing, but performance road cars increasingly use technology including carbon-ceramic discs and sophisticated multi-piston braking systems.
The same thinking has filtered into the aftermarket. UK Volkswagen Group performance specialist Awesome GTI, for example, supplies upgraded braking components for Volkswagen, Audi, SEAT, CUPRA and Skoda models, including performance brake kits, discs and pads.
For enthusiasts taking a car onto a circuit, improving braking can be just as important as adding more power. Better resistance to brake fade and more consistent performance over repeated hard stops can make a noticeable difference during a track session.
4. Aerodynamics
Few areas of Formula 1 receive as much attention as aerodynamics.
Teams spend enormous amounts of time understanding how air moves around a car, searching for ways to generate downforce while reducing unnecessary drag.
A road-going hatchback clearly doesn’t require the aerodynamic complexity of an F1 car, but the same basic principles still apply.
Splitters, diffusers, spoilers and carefully designed air intakes can all influence the way a performance car behaves at speed.
Manufacturers increasingly use wind tunnels and computational fluid dynamics when developing road cars, particularly higher-performance models.
The result is that aerodynamic design is no longer simply about making a car look aggressive. On the right vehicle, those components have a genuine job to do.
5. Adjustable Suspension
A Formula 1 car is set up specifically for the circuit it’s racing on.
Teams alter suspension settings depending on factors including track surface, corner characteristics and kerbs. Road cars obviously need to cope with a much wider variety of conditions, but adjustable suspension has brought some of that flexibility to performance-car owners.
Adaptive dampers can now alter the behaviour of a car depending on the selected driving mode, while aftermarket coilovers allow enthusiasts to make more substantial changes to ride height and handling characteristics.
Specialists such as Awesome GTI offer suspension upgrades from established performance brands for cars including the Golf GTI, Golf R, Audi S3 and CUPRA models. These range from lowering springs designed primarily for road use through to more comprehensive coilover setups suited to drivers looking for greater control over their car’s handling.
It’s particularly relevant for drivers who use the same vehicle both on the road and during occasional track days.
The objective isn’t to turn a Golf GTI into an F1 car. It’s to apply the same principle: suspension setup has a significant influence on how effectively a car can use the performance available to it.
6. Hybrid Performance
For years, hybrid technology was largely associated with improving fuel economy.
Motorsport helped demonstrate that electrification could also be used to make cars faster.
Modern Formula 1 power units combine a turbocharged internal combustion engine with sophisticated electrical systems, while other racing categories have also embraced different forms of electrification.
Performance road cars have followed.
Electric motors can provide immediate torque, fill gaps in an engine’s power delivery and allow manufacturers to produce enormous combined outputs.
The definition of a performance engine is changing as a result.
Rather than electrification replacing performance, manufacturers are increasingly using it as another way of creating it.
7. Lightweight Materials
Adding power is one way to make a car faster. Removing weight is another.
Motorsport teams have always been obsessive about weight because a lighter car can accelerate, brake and change direction more effectively.
That has driven extensive use of materials such as carbon fibre and other lightweight composites throughout top-level motorsport.
Carbon fibre remains expensive, so you’re unlikely to find an entire carbon monocoque underneath an ordinary hot hatch anytime soon. But lightweight materials have steadily become more common in performance road cars.
Carbon-fibre roofs, aluminium suspension components and lightweight wheels all follow the same basic philosophy.
Reduce unnecessary mass and you can improve performance without necessarily increasing engine output.
Motorsport Is Still the Ultimate Testing Ground
The relationship between racing cars and road cars isn’t as simple as taking a component from Formula 1 and bolting it onto a Golf GTI.
Road cars have completely different requirements. They need to be comfortable, reliable and capable of covering thousands of miles in conditions a racing car will never experience.
But the philosophy behind their development often overlaps.
Whether it’s improved braking, better suspension or extracting more performance from an engine, many of the things enthusiasts and specialists such as Awesome GTI focus on today have parallels with the development work taking place in motorsport.
The cars might be very different, but the pursuit of better performance hasn’t changed much at all.
