What is Miles per pound?

  • What is the best way of comparing fuel costs?
  • Miles per pound shows you how far new cars could go on a quid
  • All cars can be compared more easily
  • Parkers shows the fuelling differences between petrol, diesel and EVs

Used as a yardstick for comparing how much fuel or energy all types of cars use, the miles per pound (mpp) figure helps people decide between different options by showing in simple terms how far you can go for your money.

Why miles per pound?

Miles per Pound

The Parkers miles per pound (mpp) figure is a new and simple way of comparing the cost to run all cars on sale in the UK today. And it's really simple - using official 'real-world' fuel consumption figures and constantly updated energy and fuel prices, we can show you how far all cars can go for the pound in your pocket.

We devised the mpp figure as a way of demystifying the running costs of Electric Vehicles (EVs) because above and beyond their range, and how long they take to charge, there is little uniformity in how carmakers express just how much energy they use.

As interest in EVs grows, confusion reigns as buyers struggle to undertand how plugging in will affect them. Miles per pound takes away that confusion and generates an 'energy economy' figure that is relateable for anyone. In a nutshell, we tell you how far and efficiently any EV will go after plugging it in at home and topping it up on domestic electricity.

We can calculate this because all EV manufacturers publish a variety of energy consumption figures, such as Wh/mi (Watt hours per mile) and kWh/100km (Kilowatt hours per 100km, or 62 miles). But as most people think of electricity in terms of what they pay for their bill, we think it makes much more sense to show people how much it costs - not the amount of electricity used - to cover a typical real-world journey.

The mpp figures for each car can be found in the 'running costs' segment of each review.

What does miles per pound mean for you?

In a nutshell, with this figure you'll be able to directly compare how much any car costs to take on a journey. For EVs that means how much the electricity costs, and for other cars, that'll be how much petrol or diesel you need to pump in at the filling station. This will help potential owners understand the overall running costs of a car in real-world terms that are simple to understand.

For EVs, we base the price on the typical UK domestic cost per Kilowatt hour (kWh) on a domestic tariff (expressed on your bill in pence). This figure should be used as a representative guide, as the cost of domestic tariffs can vary wildly. We also display a public charging figure, which is taken from a variety of sources that reflect the more expensive and varied costs of hooking up. While most electric car owners favour charging at home, public charging values are also displayed for the sake of a comparison.

For petrol and diesel, we're basing our fuel numbers on the AA Fuel Price Reports, which reflects the national average and is updated weekly, and the official WLTP fuel consumption figures as published by all car manufacturers today. As fuel prices rise and fall, the mpp figures are also changeable. 

How far is a typical car likely to go?

Tesla Model S Supercharging

If it's an electric car, the numbers will be much higher than those for a petrol or diesel car. As of October 2019, the Top 10 most efficient EVs looked like this:

  • Kia e-Niro First Edition – 33.1mpp
  • Tesla Model 3 Standard Range – 32.3mpp
  • Volkswagen e-Golf – 30.8mpp
  • BMW i3 – 30.0mpp
  • Tesla Model S Long Range – 30.0mpp
  • Tesla Model 3 Long Range – 30.0mpp
  • Tesla Model S Performance – 29.2mpp
  • Nissan Leaf 62kWh – 26.9mpp
  • Tesla Model X Long Range – 24.6mpp
  • Tesla Model X Performance Ludicrous – 23.9mpp

The Top 10 bestselling cars in the UK for January-October 2019 - a mix of petrols and diesels - looked like this* (as of October 2019)::

  • Ford Fiesta – 6.9mpp - 10.1mpp
  • Volkswagen Golf – 5.6mpp - 9.9mpp
  • Ford Focus – 5.9mpp - 10.8mpp
  • Vauxhall Corsa – 6.5mpp - 7.7mpp
  • Nissan Qashqai – 6.7mpp - 9.0mpp
  • Mercedes-Benz A-Class – 5.8mpp - 10.8mpp
  • Volkswagen Polo – 6.7mpp - 9.3mpp
  • Ford Kuga – 4.9mpp - 7.8mpp
  • MINI Hatch – 6.7mpp - 8.5mpp
  • Kia Sportage –  5.4mpp - 8.5mpp

As you can see, it's now simple to compare exactly how much any type of car is going to cost to run – and although you might beat these figures, they should serve as a brilliant way of comparing cars, as well as giving you a real expectation of the true cost of driving in the UK today.

Also remember that mpp figures are variable (unlike mpg), and will change as fuel prices rise and fall.

Please note: Miles per pound (mpp) is only available for cars on sale from 2017 and where WLTP data is available. It should only be used as a guide and many other factors should also be considered when purchasing a vehicle.
