How much does it cost to drive from Cardiff to Westminster?

If you're using petrol, it's gonna set you back 26 quid. In this calculation, they're saying the petrol price is 143 pence per liter, and the car's gonna guzzle down 37.5 miles for every gallon of that stuff.

Now, if you're carpooling, the cost gets split up between everyone riding. So, if there are two people in the car, it's gonna be 13 quid each (£26 divided by 2). With three buddies on board, it works out to around 8.67 quid per person (£26 divided by 3). And if you've got a full car with four people, it's only 6.5 quid per person (£26 divided by 4).

Breaking down the numbers, the fuel cost is calculated based on how far you're going and how much gas your car chugs. For this trip, you're gonna need about 18.2 liters of fuel. They figured that out by dividing the distance of 150.14 miles by the car's fuel consumption rate of 37.5 miles per gallon, and then converting that to liters 'cause, you know, the UK uses liters.

So, you take the fuel needed, which is 18.2 liters, and you multiply it by the price per liter, which is 143 pence. And voilà, you got yourself the total fuel cost for the trip from Cardiff to Westminster: 26 quid.

For 4 passengers: 4.1 £ (16.4/4) /p.

Fuel efficiency of diesel and petrol: 

Diesel Fuel: Diesel engines use less fuel than petrol ones. Diesel fuel's higher energy density and diesel engines' superior thermal efficiency are the main reasons. Diesel fuel has more energy per litre or gallon than petrol, hence diesel engines can extract more energy. Diesel engines also have larger compression ratios, improving thermal efficiency. Diesel vehicles get better fuel efficiency and travel farther per gallon or litre than petrol vehicles of equal size and performance. 
Fuel efficiency is lower for petrol engines than diesel engines. Petrol is still an effective internal combustion engine fuel, but it has less energy density than diesel. This means petrol engines may need more fuel than diesel engines to function similarly. In recent years, turbocharging and direct injection have increased petrol engine fuel efficiency, closing the gap between petrol and diesel vehicles. 
Due to their higher energy density and thermal efficiency, diesel engines are more fuel-efficient than petrol engines. Diesel and petrol vehicle fuel efficiency can also be affected by driving habits, vehicle design, and other variables.
