How much is the expense of driving from Southampton to Llanelli?

The expense of driving from Southampton to Llanelli, using petrol as the fuel source, amounts to £31.5. This calculation derives from considering the petrol price as 143 pence per liter and the car's fuel efficiency at 37.5 miles per gallon. When carpooling with two passengers, the cost of the trip per passenger is halved to £15.75 (£31.5 divided by 2). With three passengers, the expense drops to approximately £10.5 per passenger (£31.5 divided by 3), and with four passengers, it's reduced further to £7.88 per passenger (£31.5 divided by 4).

To delve into the details of the calculations, the fuel cost computation is reliant on the distance traveled and the car's fuel consumption rate. For the journey from Southampton to Llanelli, approximately 22 liters of fuel would be required. This amount is determined by dividing the distance of 181.6 miles by the car's fuel consumption rate of 37.5 miles per gallon, and then converting from gallons to liters using the conversion factor of 4.54609 liters per gallon.

Multiplying the fuel needed by the petrol price per liter results in the total fuel cost of £31.5 for the trip. This breakdown illustrates the impact of various factors, such as fuel price and consumption rate, on the overall cost of the journey, providing insights for individuals planning similar trips and requiring budget estimates.
 

Diesel cost from Southampton to Llanelli.

The trip with diesel fuel costs 19.9 £ (151p/lt, 62.7 mpg).
For 2 passengers: 9.95 £ (19.9/2) /p.
For 3 passengers: 6.63 £ (19.9/3) /p.
For 4 passengers: 4.98 £ (19.9/4) /p.

In general, diesel engines tend to have lower fuel consumption compared to petrol engines, all else being equal. This is primarily due to the higher energy density of diesel fuel and the higher thermal efficiency of diesel engines. Diesel fuel contains more energy per liter than petrol, and diesel engines are typically more efficient at converting that energy into mechanical work.

Additionally, diesel engines operate at higher compression ratios, which improves their thermal efficiency and allows them to extract more energy from each unit of fuel. As a result, diesel vehicles often achieve better fuel economy and can travel farther on a gallon or liter of fuel compared to petrol vehicles of similar size and performance.

Ultimately, the choice between diesel and petrol vehicles depends on various factors, including fuel economy preferences, driving patterns, environmental considerations, and local fuel prices and availability.
