What to Consider When Buying a Fuel-Efficient Car
1. Fuel Type: Petrol, Diesel, or Hybrid?
Hybrids often give the best fuel efficiency, especially in stop-start traffic. Petrol cars are cheaper upfront, while diesels (though rarer now) offer great highway mileage.
2. Real-World Consumption vs Claimed Figures
Always look at owner-reported mileage, not just brochure specs. Factors like driving style, traffic, and terrain heavily influence fuel use.
3. Warranty and Servicing
Cars like Hyundai, Toyota, and Kia offer 5–7 year warranties, which adds to long-term value. Look for capped-price servicing and economical parts availability.
4. Technology and Drive Modes
Eco driving modes, regenerative braking, and efficient transmissions (like CVTs and e-CVTs) can help stretch your fuel even further.

With Australian petrol prices staying well above the $2 mark in many regions, choosing a fuel-efficient car in 2025 isn’t just about going green — it’s about saving real money every week.
