Mazda CX-5 fuel consumption

1.1 L/100km between the 2.2L 4cyl turbo diesel and the 2.0L 4cyl petrol

No two engines in this range sit on the same fuel within 0.4 L/100km of each other, so every choice here changes the bill. The widest single step is from 7.2 to 8.3 L/100km on the road.

The best figure went backwards after 2012

6.8 L/100km was available in 2012; 7.2 is the best on offer in 2026, 5% more. The engine that held the old figure is no longer sold.

No model year in the data beat the 2012 figure.

725 km on a tank, at best

The 2.2L 4cyl turbo diesel has the longest legs of the range: 725 km from 58 litres, with a reserve kept back. That is Esperance to Perth (709 km) in one go, and Adelaide to Melbourne (726 km) with one stop.

Fuel for that drive, at today's medians: 51 litres and about $144 in the 2.2L 4cyl turbo diesel, against 70 litres and $167 in the 2.5L 4cyl turbo petrol — $23 between them for the same trip.

Third leanest of 4 mid-size SUVs

At 7.2 L/100km on its best engine, the Mazda CX-5 sits 1.6 L/100km behind the RAV4 (5.6) and against a class median of 7.2 — about 240 litres a year between it and the leader at 15,000 km.
