How much does a trip from London to Brighton set you back in petrol costs?

The answer: £24. In this calculation, we're considering a petrol price of 144 pence per liter and a car's fuel efficiency rated at 37.5 miles per gallon. Carpooling with two passengers reduces the cost per person to £12 (£24 divided by 2). With three passengers, the expense drops to approximately £8 per passenger (£24 divided by 3), and with a full car of four, it's just £6 per passenger (£24 divided by 4).

Now, let's dissect the numbers behind this. The fuel cost is determined by the distance traveled and the car's fuel consumption rate. For this journey, you'll need approximately 16.6 liters of fuel. Crunching the figures, that's where the total of £24 comes from for the journey from Southampton to Caerphilly.
 

 

One thing that can affect car fuel consumption is the use of air conditioning (AC) for the following reasons:

  1. Engine Load: When the AC is turned on, the compressor in the car's engine needs to work harder to cool and circulate the air. This extra workload can increase the engine's fuel consumption, especially during city driving or when the car is idling.

  2. Drag Effect: Running the AC can also increase aerodynamic drag, particularly at higher speeds. This means the engine needs to work harder to maintain speed, resulting in higher fuel consumption.

  3. Accessory Load: In addition to the AC compressor, other electrical components such as the blower fan and condenser fan also draw power from the engine when the AC is running. This increases the overall electrical load on the engine, leading to higher fuel consumption.

  4. Driving Conditions: The impact of AC on fuel consumption can vary depending on driving conditions. For example, using the AC while driving at lower speeds or in stop-and-go traffic may have a more significant effect on fuel consumption compared to highway driving.

  5. Efficiency Settings: Some cars come equipped with features like "Eco" mode or variable AC compressor speeds, which can help reduce the impact of AC on fuel consumption. Using these features can help optimize fuel efficiency while still keeping the cabin cool.

Overall, while using the AC can increase fuel consumption to some extent, it's often a necessary trade-off for comfort, especially during hot weather. However, minimizing AC usage when possible, such as using the car's ventilation system or rolling down windows at lower speeds, can help mitigate its impact on fuel consumption.
