most fuel efficient hatchback australia

In Australia, the most fuel‑efficient hatch that actually drinks petrol is the Toyota Yaris Hybrid, sipping about 3.3–3.8 L/100 km (ADR combined) if you drive like a sensible adult.

If you want something bigger, the Corolla Hybrid hatch does around ~4.0–4.2 L/100 km, while Honda’s Civic e:HEV hatch sits near ~4.2 L/100 km and feels smug about it.

Yes, EV hatches use zero petrol, but the question was fuel efficiency, not electrons, so let’s keep the goalposts where they are.

Real‑world results depend on traffic, tyres, and right‑foot enthusiasm; when shopping (try Tradingpost), eyeball service history and warranty.
