Before we go into how to cut fuel consumption, I would like to find out,
- exactly how far can a supercar go with just one gallon of fuel, and
- just how much does driving style affect fuel consumption?
Jeremy Clarkson of Topgear has the demonstration for us.
After watching the whole video, you'll know that driving style does play a key role in fuel consumption. Even a BMW M3 can be more efficient than a Toyota Prius!
But exactly what makes a good driving style? What's more, do other factors also play a part in fuel consumption? We have the answer below!
Here's the summary
- Shape --> Aerodynamics --> Air resistance --> Drag --> Drag coefficient
- Weight --> Light material
- Less cargo and fewer baggage
- Tire pressure
- Slower Drive
The more streamlined the car is, the better the aerodynamics is, which leads to lower air resistance and thus lower drag and drag coefficient. The lighter the car is, the more fuel efficient. Properly inflated tires minimise contact with the ground and thus friction with the road. Finally, the optimal fuel efficient driving speed is 55 mph (88kph).

Hope you have learnt how to save money on the road and understood after the science behind it. Let's start driving wisely for the weekends!
