Diesel cost from Plymouth to Dumfries.

The trip with diesel fuel costs 46.2 £ (151p/lt, 62.7 mpg).
For 2 passengers: 23.1 £ (46.2/2) /p.
For 3 passengers: 15.4 £ (46.2/3) /p.
For 4 passengers: 11.55 £ (46.2/4) /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.
