The most fuel efficient micro and light cars in Australia

If you’re looking to save money on a small runaround, you’re probably hoping to save on fuel too.

In the micro and light car categories, where electric and hybrid options are few and far between, there are a range of petrol models to choose from.

We’ve compared cars in the micro, light under $30,000, and light over $30,000 categories on the VFACTS sales charts to see which performs best on claimed fuel economy.

For each model we’ve only taken the best-performing variant in the respective range, as some trim levels, powertrain, or transmission options can create different figures to those quoted below.

The electric offerings in this segment are limited to the Fiat 500e, Abarth 500e, and the MINI Cooper SE, which will be covered in a separate article.

Toyota Yaris

The sole hybrid-only offering in this segment, the Toyota Yaris dominates in the fuel economy rankings at just 3.3 litres per 100 kilometres on the combined cycle.

The most fuel efficient micro and light cars in Australia

With a 36L fuel tank, the Yaris can offer a reasonable cruising range for a small car as well.

Given it’s not a plug-in hybrid, there’s no battery-only range for the Yaris. The electric motor kicks in at low speed, and can also assist the engine if you need more performance at higher speeds.

There is a downside, however, as the two Yaris variants are relatively pricey, with the lower-level SX starting at $30,190 before on-road costs and the ZR at $33,260 before on-roads.

Specifically the GL Auto variant is the most efficient Swift, which features a 1.2L four-cylinder engine and a 37L fuel tank.

The GL Navi also posts the same figures and is available for $23,490 before on-road costs in Queensland, while the GL Auto can be purchased across the rest of Australia for $24,490 before on-roads.

Fiat 500

Leader in the micro car category is the Fiat 500, whose automatic Dolcevita variant records a combined 4.8L/100km.

While you don’t get wireless phone connectivity or a large boot, you do get a 35L fuel tank that’s on a par with most rivals.

Although it is efficient, the 500 is the first car on this list to require more expensive 95 RON premium unleaded petrol.

Mazda 2

The Mazda 2 matches the A1 with its combined 5.3L/100km, but only needs cheaper 91 RON unleaded petrol.

Volkswagen Polo

Two Polo variants claim 5.4L/100km, however both require 95 RON premium unleaded petrol and are the most expensive in their VFACTS segment.

At $29,490 before on-road costs, the Polo Life barely sneaks into the sub-$30,000 bracket.

The Life also shares its 1.0L turbocharged three-cylinder with the Polo Style, which is priced at $32,540 before on-roads.

The Polo also features the second-best boot capacity in its segment, however it’s lacking wireless smartphone mirroring unless you opt for a vehicle with built-in satellite navigation.

Volkswagen offers five-year, unlimited-kilometre warranty across the Polo range.

Kia Picanto

The tiny Picanto matches the bigger Polo’s combined 5.4L/100km – and its ‘micro car’ frame still fits five doors.

The Picanto Sport is the most efficient in the range and starts at $17,890 before on-road costs, with the top GT-Line variant raising the economy to 6.0L/100km and the price to $21,290 before on-roads.

Abarth 695

The 695 is expensive and thirsty for its size, coming in with a claimed 5.8L/100km on the combined cycle.

With a 1.4L turbocharged four-cylinder, the automatic variant posts more efficient figures than its manual counterpart but demands a price tag that is $2000 more expensive.

At $39,990 before on-road costs, the 695 also drinks 95 RON premium unleaded petrol.

Abarth only offers a three-year, 150,000km warranty alongside wired Apple CarPlay and Android Auto.

MG 3

The MG 3 is the cheapest new car on sale in Australia, but its claimed fuel economy of 6.7L/100km means it may not be the cheapest to run.

MG 3

That’s a high figure for such a cheap car, and is more expensive to run due to its requirement of premium unleaded petrol and a 45L tank.

Like the Kia Picanto, the MG 3 has a seven-year, unlimited-kilometre warranty.

Hyundai i20 N

As one of the few performance-oriented cars on this list, the i20 N performs the worst in terms of fuel efficiency with a claimed 6.9L/100km on the combined cycle.

The hot i20 N comes with a 1.6L turbocharged four-cylinder engine that comes at a detriment to its fuel economy… but makes it the quickest car on this list.

The i20 N starts at $34,990 before on-road costs but lacks wireless phone connectivity, although Hyundai offers a five-year, unlimited-kilometre warranty.
