What's the cost of a drive from Southampton to Cwmbran?

The journey, powered by petrol, sets you back £21.2. In this calculation, we're crunching numbers based on a petrol price of 143 pence per liter and a car's thirst of 37.5 miles per gallon. If you're carpooling with a buddy, that's £10.6 each (£21.2 divided by 2). With a trio onboard, it drops to around £7.07 a head (£21.2 divided by 3), and with a full car of four, it's a mere £5.3 per person (£21.2 divided by 4).

Let's dig into the math behind it. The fuel expenditure hinges on the distance covered and the car's efficiency. For this particular jaunt, you're looking at guzzling down roughly 14.8 liters of fuel. Crunching the numbers, that's where the £21.2 total comes from for the trip from Southampton to Cwmbran.
 

Diesel cost from Southampton to Cwmbran.

The trip with diesel fuel costs 13.4 £ (151p/lt, 62.7 mpg).
For 2 passengers: 6.7 £ (13.4/2) /p.
For 3 passengers: 4.47 £ (13.4/3) /p.
For 4 passengers: 3.35 £ (13.4/4) /p.

Diesel cars generally have lower fuel consumption compared to petrol cars for the following reasons:

  1. Higher Energy Density of Diesel Fuel: Diesel fuel contains more energy per liter compared to petrol. This means that for the same volume of fuel, diesel engines can generate more power and travel a greater distance, resulting in lower fuel consumption.

  2. Increased Thermal Efficiency of Diesel Engines: Diesel engines operate at higher compression ratios compared to petrol engines. This higher compression ratio allows diesel engines to extract more energy from each unit of fuel. As a result, diesel engines are typically more thermally efficient, translating into lower fuel consumption.

  3. Greater Torque at Lower RPM: Diesel engines tend to produce more torque at lower engine speeds (RPM) compared to petrol engines. This characteristic allows diesel vehicles to maintain better fuel efficiency, particularly during steady-state cruising, as they require less throttle input to maintain speed.

These factors combined contribute to the generally lower fuel consumption observed in diesel cars compared to their petrol counterparts.
