What is the financial outlay associated with traveling from Plymouth to St Helens by car?

The journey, powered by petrol, incurs a cost of £49.6. In this computational scenario, the price of petrol is assumed to be 144 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 £24.8 (£49.6/2). For a trio of passengers, the cost per person reduces to £16.53 (£49.6/3), and for a quartet of passengers, it further decreases to £12.4 (£49.6/4).

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 283.92 miles, this computation entails multiplying 283.92 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 34.4 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 34.4 liters of fuel at a rate of 144 pence per liter, the cumulative cost equals £49.6.

In summation, the total fuel expenditure for the trip from Plymouth to St Helens stands at £49.6.

Diesel cost from Plymouth to St Helens.

The trip with diesel fuel costs 34.4 £ (167p/lt, 62.7 mpg).
For 2 passengers: 17.2 £ (34.4/2) /p.
For 3 passengers: 11.47 £ (34.4/3) /p.
For 4 passengers: 8.6 £ (34.4/4) /p.

Significant factors contributing to diesel cars generally having lower fuel consumption than petrol cars are:

  1. Higher Thermal Efficiency: Diesel engines typically operate at higher compression ratios than petrol engines. This higher compression ratio allows diesel engines to extract more energy from each unit of fuel, resulting in greater thermal efficiency. As a result, diesel vehicles can achieve better fuel economy compared to petrol vehicles.

  2. More Torque at Lower RPM: Diesel engines tend to produce more torque at lower engine speeds (RPM) compared to petrol engines. This characteristic enables diesel vehicles to perform more efficiently during steady-state driving conditions, requiring less throttle input to maintain speed. Consequently, diesel cars often exhibit lower fuel consumption, especially in highway driving scenarios.
