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

The answer: £26.7. 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 £13.35 (£26.7 divided by 2). With three passengers, the expense drops to approximately £8.9 per passenger (£26.7 divided by 3), and with a full car of four, it's just £6.68 per passenger (£26.7 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 18.5 liters of fuel. Crunching the figures, that's where the total of £26.7 comes from for the journey from Penarth to Portsmouth.
 

 

The following reasons can affect car fuel consumption:

  1. Traffic Congestion: Driving in heavy traffic often involves frequent stops and starts, as well as idling in traffic queues. This constant acceleration and deceleration can lead to increased fuel consumption compared to driving on open, free-flowing roads.

  2. Vehicle Weight: Carrying excess weight in the vehicle, such as heavy cargo or unnecessary items, can increase fuel consumption by putting additional strain on the engine. Removing unnecessary weight can improve fuel efficiency.

  3. Elevation Changes: Driving on roads with steep inclines or declines can affect fuel consumption, especially for vehicles with less powerful engines. Climbing uphill requires more power from the engine and thus more fuel, while descending downhill may require additional braking and fuel to maintain control.

  4. Weather Conditions: Adverse weather conditions such as rain, snow, or strong winds can affect fuel consumption. These conditions may require drivers to adjust their speed and driving behavior, impacting fuel efficiency. Additionally, extreme temperatures can affect engine performance and fuel consumption.
