Road trips are one of the most exciting and enjoyable ways to explore a new area or revisit an old favorite with cars. But while they can be an incredible experience, long-distance driving means spending extra money on fuel. If you’re planning a road trip, finding a car that balances budget-friendly efficiency is key.

After days of researching the most fuel-efficient vehicles available, we have narrowed down our list to nine top options. So take a closer look to learn more about how to find out which model might be perfect for your next journey.

Here are the nine cars with the best fuel efficiency for long trips:

Mitsubishi Outlander

The Mitsubishi Outlander is already one of the most fuel-efficient 7-seater SUVs, with a combined rating of 27 MPG – pretty impressive! But why not take advantage of that efficiency even more? By activating Eco Mode, you can reduce energy consumption and get an even cleaner ride out of the Mitsubishi Outlander. Now that’s a smart move that will make your wallet smile. So if you’re looking for an affordable, efficient car option, look no further than the Mitsubishi Outlander.

BMW i3

BMW’s i3 is setting the benchmark for hybrid cars with its unbeatable fuel efficiency and low emissions performance. It produces just 1.22 tonnes of CO2 annually, averaging an awe-inspiring 129 Wh/km energy usage – far lower than many other competing hybrids. As if that wasn’t enough, BMW i3 owners can rest easy knowing they’ll only have to recharge or refill their car every 260 km. This is perfect for busy city driving or longer journeys too.

Hyundai Ioniq PHEV

It’s no surprise why the Hyundai Ioniq PHEV has become popular in Australia. Its estimated electric range of 63 kilometres ensures that it can meet the needs of most car owners. However, while it packs the power of an electric motor, the engines are unfortunately quite outdated. Thankfully Hyundai is slowly but surely transitioning its vehicles to more advanced electric drive technology. This will hopefully be a priority for them going forward.

Mercedes Benz C300e

The Mercedes Benz C300e is an impressive feat of technology. Its electric range of 52 kilometres indeed makes it a hit with families and city-dwellers. Moreover, its estimated 157Wh/km consumption shows the car is environment-friendly and economical. This model also comes with Mercedes’ trademark top-notch safety features. It is because safety always comes first with Mercedes. But it doesn’t stop there; the C300e has plenty of entertainment options, too, perfect for long journeys!

Renault Megane 1.5

Regarding compact cars, Renault’s 1.5 Megane is an impressive option. It provides an ideal balance between fuel economy, emissions, and performance. All of which contribute to its reputation as having exceptional pulling power despite its size. Comparatively speaking, the Renault Megane outperforms many similar models in its class. It also remains one of the most favoured options regarding quality, performance, and value.

Volkswagen Polo 70TSI

Volkswagen Polo 70TSI is an excellent option if you’re looking for city cars that can do everything. Its big cabin makes it perfect for running errands in the city and longer trips, while the modern touches mean you can always stay connected. In addition, driver tiredness recognition helps ensure safety on the road. At the same time, Apple CarPlay and Android Auto make accessing music maps easier than ever. All of this comes together in this appealing city car that won’t have you asking ‘what if’.

Kia Picanto

Kia has outdone itself with its Picanto model, the smallest car Kia offers. What’s most impressive is that it is super fuel-efficient while keeping its four-cylinder engine. This performance goes a long way in showing that the company’s hybrid powertrains will be successful. In a way, they offer the same economy and vigour as the Kia Picanto’s engine. Already capable of managing 4.9L/100km, Kia’s newest model is sure to impress due to its eco-friendly capabilities and powerful acceleration potential.

Mini Cooper D Hardtop

The Mini Cooper D Hardtop Countryman is an example of ‘big things come in small packages’. Despite its compact size, it provides a spacious interior and an impressive array of safety features. This has earned it a five-star ANCAP safety certification. In addition, it features the latest technology to keep drivers safe and secure, from automatic emergency braking and reversing collision avoidance to optional fatigue detection.

Skoda Fabia

The Skoda Fabia is an impressive car, and its tiny 1.0-litre engine is no exception. It is powerful enough to send power to the front wheels and offers incredibly economical figures of just 4.5L per 100km. That makes it easy on your wallet while allowing you to make long journeys without needing to stop frequently. Skoda reckons you can travel as far as 1,125km on one gas tank!
