Why fuel economy still matters in 2025
Let’s be honest, fuel prices aren’t getting cheaper any time soon, and while electric cars are growing in popularity, most of us still want the flexibility, comfort and familiarity of petrol, diesel or hybrid cars. That’s where fuel efficient used cars come in.
Choosing a car with great mpg (miles per gallon) means you’ll spend less time at the pumps and more time enjoying the drive. Whether you’re commuting every day, clocking motorway miles, or just pottering around town, picking one of the best mpg used cars will save you money in the long run.
Our top fuel efficient used cars in 2025
Here’s a closer look at some of the most economical used cars you can find on the market right now, perfect for anyone shopping with Motor Match.
Mazda 2 Hybrid - up to 74.3 mpg
If you want something small, reliable and cheap to run, the Mazda 2 Hybrid is a gem. It’s basically the Toyota Yaris in disguise, which means reliability and brilliant hybrid tech. Around town, it’ll happily switch to electric power for short bursts, and you can expect 55-65 mpg in real world driving.
Why choose it? It’s perfect if you’re a city driver or first time buyer who wants a frugal hatchback that still feels fun to drive.
Toyota Yaris Hybrid - up to 70.6 mpg
The Yaris has been around for years, and it’s earned a reputation as one of the best cheap to run cars on the used market. Insurance is low, servicing costs are affordable, and Toyota’s hybrid system is famously durable.
Real world economy sits in the 55-65 mpg range, and if you stick to town driving, you’ll see the higher end of that scale.
Why choose it? If you want peace of mind with long warranties (Toyota offers up to 10 years if serviced with them), this is one of the most hassle free choices around.
Renault Clio E-Tech - up to 67.3 mpg
Want a touch of style with your savings? The Renault Clio E-Tech hybrid is practical, modern and surprisingly spacious for a small hatchback. Owners regularly report 50-60 mpg in everyday driving, and you’ll also get a car that feels a bit more premium inside compared with some rivals.
Why choose it? Perfect if you want economy without sacrificing looks or comfort.
Toyota Prius Plug-in Hybrid - up to 67.3 mpg
The Prius has long been the poster child for hybrid efficiency, and the plug-in version takes things up a notch. With an electric only range of around 30 miles, most short commutes can be done without touching a drop of petrol.
When you’re using both petrol and electric, the Prius averages around 67 mpg overall, making it one of the smartest options for those who mix town and motorway driving.
Why choose it? Great for drivers who want to dip a toe into EV driving but aren’t ready to go fully electric yet.
Toyota Corolla Hybrid - around 62.8 mpg
If you need a slightly bigger hatchback, the Corolla is one of the most fuel-efficient family cars you can buy. Stylish, comfortable, and backed by Toyota’s strong reliability, it’s a safe bet for anyone looking for a sensible yet modern drive.
Why choose it? The perfect all-rounder if you want space, comfort and economy in one package.
Hyundai IONIQ Plug-in Hybrid - up to 250 mpg combined
Yes, you read that right! Thanks to its 40-mile electric range, the IONIQ can deliver crazy high mpg figures when used correctly. If you charge at home and mostly do short trips, you’ll barely touch the petrol tank.
Why choose it? Ideal if you’ve got off road parking and can charge up regularly.
Volkswagen Golf TDI - around 49.6 mpg
Sometimes, you can’t beat a good diesel for long distance economy. The VW Golf diesel is a motorway king, comfortable, stable, and capable of close to 50 mpg even when cruising at speed.
Why choose it? Best for long distance drivers and commuters who want a mix of efficiency and everyday usability.
Skoda Octavia TDI - 50+ mpg
Big boot, comfortable ride, and excellent mpg for a car its size. The Octavia diesel is one of the most underrated bargains on the used market.
Why choose it? Great for families who want practicality and low running costs.
Petrol vs Diesel vs Hybrid: which is right for you?
- Hybrid/Plug-in Hybrid: Best for town driving, school runs, and short commutes. You’ll save the most on fuel if you do regular stop start journeys.
- Diesel: Still the go to for high mileage drivers who spend most of their time on the motorway.
- Petrol: Cheaper to buy used, and fine for lower mileage drivers who don’t want the extra cost of hybrid systems.
Getting the best mpg from your used car
Even the most efficient car won’t save you money if it’s driven poorly. Here are a few tips:
- Keep tyres properly inflated (low pressure means higher fuel bills).
- Don’t carry unnecessary weight, clear out the boot.
- Drive smoothly, hard acceleration and heavy braking burn fuel.
- Service your car regularly to keep the engine running at its best.
