Best MPG cars UK

The most fuel-efficient cars you can buy in the UK today.

1. BMW 330e

MPG = 201.8. The BMW 330e not only looks great but it also offers great fuel economy. The MPG is 201.8 – 217 when you choose the 2019 version and onwards which is one of the best you can get! We think the BMW 330e is one of the best MPG cars because it’s sporty, capable and stylish. Not only that but it’s fast too, so you don’t have to compromise on fuel economy and performance. As you’d expect, it comes with BMWs high level of precision and quality. The ‘e’ part of its name doesn’t mean it’s fully electric though and instead is a dynamic plug-in hybrid. 

2. Mercedes-Benz E300de.

MPG = 176.6. The Mercedes-Benz E300de is one of the best cars for MPG and can offer around 176.6-201.8 MPG. You’ll need to choose a model from 2016 onwards to benefit from these highly fuel-efficient vehicles. Just like the BMW 330e above, it’s one of the more premium cars on our list and comes with all the bells and whistles Mercedes is known for. It’s also a plug-in hybrid model but what sets it apart from its competitors is it’s the ONLY diesel-electric powered hybrid car on the market. 

3. Mercedes-Benz GLE.

MPG = 353.1. Another Mercedes-Benz competing for the title of best MPG car is the GLE 350de. It’s a large SUV which is a perfect family car for busy lives. It’s another fine example of a plug-in hybrid which combines capability with stylish looks. The GLE 350de only offers around 58 miles of electric driving but it’s more than enough for the school run or dotting around town. Using a car like this in that ay though would be a shame as performs best at high speeds on open roads.

4. Vauxhall Corsa.

MPG = 70.6. The Vauxhall Corsa is one of those cars which is hugely versatile. It’s great for city driving and short journeys but also offers great fuel economy too. We like the Vauxhall Corsa for newly qualified drivers as you can buy a second-hand for under £10k and they’re cheap to run too. It’s a great compromise if you don’t want to buy a hybrid car just yet and the diesel version will offer around 70.6 MPG. 

5. Skoda Octavia.

MPG = 67.3. The Skoda Octavia is one of the best MPG cars you can buy on a budget! The Octavia has also been featured on our list of the best cars for camping and the best cars for carrying golf clubs, so it’s perfect for your weekend adventures! The Skoda Octavia is really easy to live with and reduces how often you’ll be heading to the petrol station to fill up. On the inside, there’s a more than generous amount of space and the boot space is huge too!

6. Suzuki Swift.

MPG = 64. The Suzuki Swift is a great example of a supermini that packs a punch, and it’s one of the cheapest MPG cars you can buy too. The current version of the Suzuki Swift is a mild hybrid which means it can’t run on electric power alone and instead the electric battery is there to boost the petrol engine. The Suzuki Swift is small but mighty and it won’t cost you an arm and a leg either! 

7. Hyundai IONIQ.

MPG = 60. The Hyundai IONIQ is a dependable and impressive plug-in hybrid. It offers great fuel economy and it’s good value for money too. It’s also cheap to run and comes with low insurance rates and maintenance costs. The Hyundai IONIQ is a great example of a plug-in hybrid which is a true all-rounder. It’s not the most exciting car on our list but if you’re after a car with high MPG and a comfortable ride, it could be the car for you.

8. Renault Clio.

MPG = 67.2. And, finally, we end our list of the best MPG cars with the popular Renault Clio. The Renault Clio is a fuel-efficient diesel car. It’s long been a favourite amongst UK drivers and it’s easy to see why. It is reliable, economical and won’t leave you out of pocket. The electric motor offers around 39 miles of all-electric driving and supports the powerful 1.6-litre diesel engine. The newest version of the Clie comes with plenty of tech as standard and great fuel economy.
