In today’s world, fuel efficiency is no longer just a perk—it’s a necessity. Whether you’re looking to save money at the pump or reduce your carbon footprint, understanding miles per gallon (MPG) is crucial. MPG is the yardstick we use to measure just how far your car can travel on a single gallon of fuel, roughly 4.5 liters. This can range dramatically, from a mere 11 miles per gallon in some less efficient vehicles to impressive figures in more economical models.
While diesel engines have traditionally been the champions of fuel economy, the automotive landscape is shifting. With the rising popularity of petrol and hybrid cars, especially in markets like the UK, it’s essential to explore the best options across these categories. This guide will dive into the cars with the highest MPG, covering both petrol and hybrid vehicles to give you a comprehensive overview.
Before we jump into the list, it’s important to remember that a car’s actual MPG can vary based on driving habits. A more aggressive driving style will naturally consume more fuel than a smoother, more consistent approach. Think of it like this: a race car driver is likely to have a heavier foot on the pedal compared to a careful everyday driver.
For the sake of fair comparison, the cars listed below are ranked according to their official average fuel economy ratings. These figures are determined by the Worldwide Harmonised Light-duty Vehicles Test Procedure (WLTP), a standardized testing method designed to provide realistic fuel consumption figures.
Here are some of the top cars on the market that boast exceptional fuel efficiency:
- BMW 330e
- Toyota Prius
- Suzuki Swift
- Toyota Corolla Touring Sports
- Hyundai IONIQ
- Mercedes-Benz E300 de
- Peugeot 208
- Vauxhall Corsa
- Skoda Octavia
- Volkswagen Golf

How to Maximize Your Car’s Fuel Efficiency
Choosing a car with high MPG is the first step towards fuel savings, but optimizing your driving habits can further enhance your fuel economy. Whether you drive one of the cars with highest MPG listed above or another vehicle, these tips can help you get the most miles out of every gallon.
Modern cars, even those with standard petrol engines, are increasingly fuel-efficient due to advancements like turbochargers and hybrid technology. However, driving style and vehicle maintenance play a significant role in achieving optimal MPG.
Simple Changes for Better Fuel Consumption:
1) Minimize Air Conditioning Use
Reducing your reliance on air conditioning can lead to noticeable fuel savings. Air conditioning systems place a significant load on the engine, requiring extra power and increasing fuel consumption. Whenever possible, opt for natural ventilation by opening windows or using the car’s ventilation system without engaging the A/C compressor.
2) Adopt Smooth Driving Techniques
Smooth and consistent driving is key to fuel efficiency. Avoid harsh acceleration and braking, and maintain a steady speed, especially on motorways. Anticipate traffic flow to minimize unnecessary braking and acceleration. Gentle acceleration from a standstill also reduces strain on the engine and conserves fuel.
3) Combine Short Trips and Plan Routes
Cold starts are less fuel-efficient as the engine needs time to reach its optimal operating temperature. Combining multiple errands into a single trip reduces cold starts and allows the engine to operate more efficiently for a longer duration. Planning your routes to avoid heavy traffic and congestion also minimizes stop-and-go driving, which consumes more fuel.
