Where fuel efficiency meets performance: Explore the most economical cars of 2024

In 2024, fuel efficiency remains a top priority for UK motorists as they navigate the challenges of rising fuel prices and the pressing need to reduce carbon emissions. The question on everyone's mind is: just how economical is your car? As we move further into the future, it's becoming ever-more crucial to consider ways to cut costs and contribute to a greener planet.

This comprehensive article is your ultimate guide to the best MPG cars available in the UK for 2024. We've scoured the market to bring you the most sought-after petrol, diesel, and hybrid vehicles that deliver exceptional fuel economy without compromising on performance or style. By opting for one of these fuel-efficient cars, you'll spend less money at the pump and significantly reduce your CO2 emissions, making a positive impact on both your wallet and the environment.

Of course, finding the perfect car is not a one-size-fits-all approach. Your ideal vehicle will depend on various factors, such as the type of journeys you typically make, the number of miles you drive per day, and even your own personal driving style is to be considered too! All of these elements play a role in determining your overall MPG usage.

To simplify your search, we at Wilsons Epsom have made it effortlessly easy for you to filter our extensive selection of cars by MPG. With just a few clicks, you can find the fuel-efficient vehicle that best suits your needs and preferences. Read on to find out more… 

What is MPG?

MPG stands for Miles Per Gallon. The term MPG is used in association with vehicles to identify the amount of miles a car can travel per gallon of fuel it uses. Let’s give you an example; if the car you drive is advertised at 43 MPG and the fuel tank has a gallon of petrol or diesel left in it, you can expect to drive 43 miles before it runs out of fuel. 

Official MPG figures are determined through WLTP testing. Introduced for new cars in 2017, WLTP stands for Worldwide Harmonised Light Vehicle Test Procedure which measures fuel economy in all new standard combustion engine cars and determines electric driving ranges for EVs, as well as emissions. 

What makes a car more economical?

With many motorists hoping to keep their weekly fuel costs down, driving more economically will help make the miles go further - plus, you’ll be doing the environment a favour too! 

So what makes a car more economical? We’ve listed the top three contributing factors and explained how each affects a car’s overall MPG:

  1. SIZE & WEIGHT - The two go hand in hand and have a significant impact on the amount of fuel a car will consume. Generally, the smaller and lighter a car is, the less fuel it will use compared to a larger and heavier vehicle, so therefore will naturally have a better MPG ratio.
  2. ENGINE TYPE - The engine type and size will have a big part to play in terms of fuel consumption. When choosing a new car, always compare petrol, diesel and hybrid options to understand which offers you the best MPG and range to suit your daily driving habits. 
  3. EMISSIONS - If you’re not ready to make the transition to an electric vehicle just yet, then you’ll need to consider the amount of emissions a petrol or diesel car emits from the exhaust pipe - this will also affect the amount of road tax you pay.

FAQS and Answers

What car gives the best MPG?

As of 2024, the car with the best MPG in the UK is the Toyota Prius, a hybrid vehicle that achieves an impressive 94.1 mpg. This exceptional fuel efficiency is a result of Toyota's advanced hybrid technology, which seamlessly combines a petrol engine with an electric motor to optimise power and minimise fuel consumption.

Is 50 mpg good for a car in the UK?

Yes, achieving 50 mpg is considered very good fuel efficiency for a car in the UK. In fact, a car with a 50 mpg rating is well above the average fuel consumption of most vehicles on the road as the average MPG for new cars is around 40-45 mpg.

What car gets 70 mpg?

In the UK, several cars can achieve or exceed 70 mpg, particularly in the diesel and hybrid categories. Some notable examples in 2024 include the Peugeot 208 diesel, Ford Fiesta diesel, Renault Clio diesel, Vauxhall Corsa diesel, and Toyota Prius hybrid.

What is a good MPG for a petrol car?

A good MPG rating for a petrol car is generally considered to be around 50 mpg or higher. This is because petrol cars typically have lower fuel efficiency compared to diesel and hybrid vehicles.

Does E10 petrol give better MPG?

E10 petrol, which contains up to 10% ethanol, is a relatively new fuel blend that has been introduced in the UK to help reduce carbon emissions. However, when it comes to fuel efficiency, E10 petrol may not necessarily provide better MPG compared to traditional E5 petrol, which contains up to 5% ethanol.

Do you get a better MPG with premium petrol?

​​In general, using premium petrol may not necessarily result in better MPG for most vehicles. Instead, using the petrol grade recommended by your vehicle manufacturer will ensure optimal performance and fuel efficiency. If your vehicle does not specifically require premium petrol, you may not see a noticeable improvement in MPG by using it, and the higher cost may outweigh any potential benefits overall.

What is the most fuel-efficient non-hybrid car?

As of 2024, one of the most fuel-efficient non-hybrid cars in the UK is the Peugeot 208 diesel. This popular supermini has been praised for its impressive fuel economy, achieving up to 73.6 mpg on the combined cycle.

Does MPG go down with age?

Yes, a car's MPG can generally decrease with age due to various factors related to wear and tear, maintenance, and technological advancements. It's important to note that the rate at which MPG decreases with age can vary greatly depending on factors such as the specific make and model of the car, how well it has been maintained, and the driving conditions it has been subjected to.

At what speed do you lose MPG?

Most cars achieve their highest fuel efficiency at steady speeds between 35 mph and 50 mph. This is because the engine is operating at a relatively low RPM, and the car's aerodynamic drag is still relatively low. As a car's speed increases beyond the optimal range, fuel efficiency typically starts to decline. The rate at which MPG decreases can vary, but this is often the case at speeds above 50-60 mph.
