What is the financial outlay associated with traveling from Portsmouth to Colchester by car?

The journey, powered by petrol, incurs a cost of £24.7. In this computational scenario, the price of petrol is assumed to be 143 pence per liter, and the car's fuel efficiency stands at 37.5 miles per gallon.

For individuals contemplating carpooling arrangements, the expenditure per traveler diminishes as the number of passengers increases. With two passengers, the cost per person amounts to £12.35 (£24.7/2). For a trio of passengers, the cost per person reduces to £8.23 (£24.7/3), and for a quartet of passengers, it further decreases to £6.18 (£24.7/4).

To provide further elucidation on the calculation process, let us dissect how the final figure is derived:

Initially, the requisite fuel quantity is determined by dividing the distance traveled by the car's fuel consumption rate. For a journey spanning 142.26 miles, this computation entails multiplying 142.26 miles by 4.54609 (liters per gallon) and subsequently dividing by the car's fuel efficiency of 37.5 mpg, resulting in a requirement of 17.2 liters of fuel.

Subsequently, the fuel expenditure is computed by multiplying the amount of fuel required by the price per liter. Given a consumption of 17.2 liters of fuel at a rate of 143 pence per liter, the cumulative cost equals £24.7.

In summation, the total fuel expenditure for the trip from Portsmouth to Colchester stands at £24.7.

Diesel cost from Portsmouth to Colchester.

The trip with diesel fuel costs 15.6 £ (151p/lt, 62.7 mpg).
For 2 passengers: 7.8 £ (15.6/2) /p.
For 3 passengers: 5.2 £ (15.6/3) /p.
For 4 passengers: 3.9 £ (15.6/4) /p.

Diesel fuel and petrol (gasoline) fuel in terms of fuel efficiency:

  • Diesel Fuel: Diesel engines are generally more fuel-efficient than petrol engines. 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 or per gallon compared to petrol, allowing diesel engines to extract more energy from each unit of fuel. Additionally, diesel engines operate at higher compression ratios, which further improves their thermal efficiency. As a result, diesel vehicles typically achieve better fuel economy and can travel farther on a gallon or liter of fuel compared to petrol vehicles of similar size and performance.

  • Petrol (Gasoline): Petrol engines are generally less fuel-efficient than diesel engines. While petrol is still an efficient fuel for internal combustion engines, it typically has a lower energy density compared to diesel fuel. This means that petrol engines may require more fuel to achieve the same level of performance as diesel engines. However, advancements in petrol engine technology, such as turbocharging and direct injection, have improved fuel efficiency in recent years, narrowing the gap between petrol and diesel vehicles.
