most fuel-efficient petrol suv australia

If you’re chasing the most fuel-efficient petrol SUV in Australia, you’ll be shopping the light-SUV end where they sip like sparrows.

Regular standouts include the Kia Stonic 1.0T DCT (around 5.4 L/100 km), Volkswagen T‑Cross 85TSI (about 5.4–5.6 L/100 km), and Toyota Yaris Cross 1.5 petrol (roughly 5.4–5.6 L/100 km); the Mazda CX‑3 is thrifty too at roughly 6.3 L/100 km.

They’re tiny, light, and about as racy as a librarian’s card—exactly why they use so little juice.

If you want truly miserly numbers, hybrids beat them handily, but you asked for petrol and we’re sticking to the brief.

Specs vary with wheels, transmissions and options; consult official documentation for exact figures.
