Mechanics cannot be everyone’s top subject – and for many, their motor vehicle is as much an enigma as a computer chip or the flight of an airplane. Yes, you’ll have a rudimentary idea of how your car works, and what you may need to maintain in order for it to continue working in the future, but you’ll be a little hazy on the scientific details of what keeps your car in a wonderful condition after it visits the garage for a service. In this guide, you’ll learn a little of the science behind the great performance of your car.


Let’s start with a part that’s less about moving sparkplugs and cylinders, and more about how you control some of the most important parts of your car. You see, your car needs a battery in order to operate – not since several decades ago did cars operate without batteries. These batteries help start the car, provide energy for windows and lights and keep your car healthy year-round.

The wiring of the electrics is incredibly important for your car’s long-term health. If your electrical systems become in some way damaged, you may be unable to start your car, use your lights, keep your windscreen clear, or use the radio within your vehicle. As such, if you notice electrical errors in your car, it’s worth taking it to the garage at your earliest convenience.


Here’s where your car finds its power, and how you can find your form in understanding exactly what happens under the hood of your motor vehicle. It’s actually simpler than you’re likely to think – but beyond the scope of this article to go into any great detail on. Instead, we’ll focus on those bits that really matter for your car’s maintenance and workings.

Those are the gearbox, the oil levels and the handling of your car. If your gearbox starts to fail, you’re going to want to take your car in to service immediately – its moving parts can quickly sheer metal from other important, and expensive, part of your engine and axel. Oil is necessary to protect from sheering, and keeps your car’s moving parts lubricated. Check it regularly and keep it topped up. Finally, if your car’s handling feels off, you should check your tire pressure – you may have a slow flat.


You may feel that your car has no science operating on its exterior – after all, it’s just a bit of metal and paintwork – but actually, it’s where some of the most interesting science takes place. Your chassis, for instance, is designed to avoid rolling, and to help you in heavy impacts in the event of a crash.

Moreover, the paintwork can be protected with high-tech sprays that keep your car looking amazing all year round. Enjoy the next generation of paint protection by buying a spray product that con coat your car in a substance that keeps it shining and looking fantastic, while also protecting it from the weather and from flicked stones that could otherwise chip your paintwork.

These three scientific insights will help you keep your car up and running – and looking great – all through the year and long into the future.
