These are the most fuel-efficient vehicles on the market

For fleet managers, professional drivers and small business owners, fuel efficiency isn’t just about saving money. Rather, it’s about improving operational efficiency and minimising your impact on the environment. Whether you're managing a fleet of delivery vehicles, operating a rideshare business or simply overseeing company cars, here’s how to choose the best fuel-efficient vehicle and make a difference to your bottom line.

Best fuel-efficient small car

Car model: Toyota Yaris Hybrid

Fuel efficiency: 3.3/100KM

Small fuel efficient cars are perfect for rideshare drivers and fleets that mainly operate in CBDs. The Toyota Yaris Hybrid gives you outstanding fuel economy without compromising on technology and safety. The hybrid system has a fuel tank capacity of 36L and optimises fuel consumption, particularly in stop-and-go city traffic – great for places like Sydney and Melbourne. It will help your business lower its fuel costs over time

Best fuel-efficient sedan

Car model: Toyota Camry Hybrid

Fuel efficiency: 4.2L/100km

Cars with great fuel economy don’t come much better than the Camry Hybrid. This sedan is a go-to choice for professionals who want a comfortable and reliable sedan to get them to client meetings or handle regular corporate travel. It has a 2.5L four-cylinder engine and electric motor, spacious interiors, the latest safety features and exceptional fuel economy. In other words, it’s a cost-effective option for businesses that want to maintain their professional image without excessive running costs.

Best fuel-efficient van

Car model: Ford Transit Custom PHEV

Fuel efficiency: TBA (combined with electric range)

Expected to hit our shores in Q3 2025 (July-September period), this is Australia’s first plug-in hybrid delivery van (PHEV) – ideal for delivery and service-based businesses. Powered by a 2.5L four-cylinder petrol engine and a 171kW electric motor, this hybrid Ford Transit Custom can be customised to run on electric power straight away or use a mix of both. That means you can use just electric power for short trips while having the backup option of petrol for long-haul operations.

Best fuel-efficient ute

Car model: Mazda BT-50 1.9L Diesel

Fuel efficiency: 7.0L/100km

Utes remain a staple for tradies and construction companies alike. The Mazda BT-50 with its 1.9L diesel engine delivers powerful towing capabilities, exceptional fuel efficiency for its vehicle type and a practical amount of load space. In other words, it’s a reliable workhorse for any business on the move.

Best fuel-efficient SUV

Car model: Toyota RAV4 Hybrid

Fuel efficiency: 4.7L/100km

A top choice for businesses that need a vehicle that balances storage space, power and great mileage. The RAV4 Hybrid will give you fuel savings while protecting your drivers with advanced safety technology. Plus being a RAV4 you can expect a comfortable drive every time – making it the best choice for executives and sales reps who are constantly on the road.

Make the right choice for your business

When you’re in the market for cars with great fuel economy for your fleet, there are a few things to keep in mind. Front-and-centre should be the total cost of ownership – look beyond just fuel consumption and factor in things like maintenance, insurance and resale value.

Also consider your driving needs. Will the vehicle be used for short city trips or long drives on the motorway? The answer might influence whether a hybrid, diesel or plug-in hybrid is the best choice.

Finally, don’t forget about government incentives. Check for any available rebates or tax benefits for fuel-efficient or electric fleet vehicles that you can write off at the end of the financial year.

Remember: cars with great fuel economy are an investment

Investing in fuel-efficient vehicles is a smart way for Australian businesses to cut down operational costs while reducing their carbon footprint. So if you’re in the market for a city-friendly hybrid, a powerful yet economical ute or a reliable van for deliveries, there are plenty of great choices around to keep your business running smoothly through 2025 and beyond.
