What's the cost of a drive from Cardiff to Plymouth?

The journey, powered by petrol, sets you back £26.1. 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 £13.05 each (£26.1 divided by 2). With a trio onboard, it drops to around £8.7 a head (£26.1 divided by 3), and with a full car of four, it's a mere £6.53 per person (£26.1 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 18.3 liters of fuel. Crunching the numbers, that's where the £26.1 total comes from for the trip from Cardiff to Plymouth.
 

Diesel cost from Cardiff to Plymouth.

The trip with diesel fuel costs 16.5 £ (151p/lt, 62.7 mpg).
For 2 passengers: 8.25 £ (16.5/2) /p.
For 3 passengers: 5.5 £ (16.5/3) /p.
For 4 passengers: 4.13 £ (16.5/4) /p.

When compared to gasoline-powered vehicles, diesel vehicles often have a lower fuel usage percentage for the following reasons:

Diesel fuel has a higher energy density than gasoline, meaning that it contains more energy per litre than gasoline does. Diesel engines are able to create more power and travel further for the same amount of gasoline, which results in a lower overall fuel consumption. This is because diesel engines also travel further.

Diesel engines operate at higher compression ratios than petrol engines, which results in increased thermal efficiency for diesel engines. Because of this increased compression ratio, diesel engines are able to extract a greater amount of energy from each individual dose of fuel. Because of this, diesel engines are often more thermally efficient, which results in a reduction in the amount of fuel these engines consume.

Diesel engines have a tendency to produce higher torque at lower engine speeds (RPM) compared to petrol engines. This is because diesel engines are more efficient than petrol engines. Because diesel vehicles require less throttle input to maintain speed, this trait enables diesel vehicles to retain superior fuel efficiency, particularly during steady-state cruising. This is especially true during the cruising phase.

In comparison to their gasoline-powered counterparts, diesel vehicles have a generally lower fuel consumption, which can be attributed to the combined effects of these particular characteristics.
