Mazda CX-60 2023: 3.3-litre inline-six petrol engine fuel efficiency revealed

---

Mazda Australia has announced the fuel efficiency figures for its new petrol inline-six engine that will debut in the forthcoming CX-60 SUV, due to launch mid year.

Mazda has stated that the fuel efficiency of its 3.3-litre petrol inline-six engine matches the fuel economy of its smaller 2.5-litre petrol four-cylinder engine – 7.4L/100km – despite having a larger displacement and two extra cylinders. 

That’s also despite the six, at 209kW/450Nm, offering around 50 percent more power and around twice the torque of the four cylinder.

According to Mazda, the design of the new, larger-displacement engine allows for a more complete combustion process by way of “a wider lean-burn range, leading to lower consumption and reduced NOx emissions”. 

The 48-volt mild-hybrid system uses an electric motor sandwiched between the inline-six petrol engine and the eight-speed automatic transmission. The motor assists with idle and low-speed input, where a combustion engine is commonly known to be the least efficient. 

However, it doesn’t stop there, with Mazda promising that its new six-cylinder engine has “a smooth operation, packaging, thermal efficiency and crash performance, as well as a characterful and involving engine note.”

Mazda forecasts that the 3.3 petrol engine will be the model’s biggest seller, with expectations that it will account for around 44 percent of customer orders.

What sort of performance is this new inline-six capable of?

Mazda’s 3.3-litre turbocharged inline-six petrol engine produces 209kW/450Nm and, in the CX-60 application, will be able to push the SUV in 6.9 seconds, 0.8 seconds quicker than the current CX-5 Turbo model. 

The 3.3-litre petrol six is able to do all this while running on 91-octane fuel.

A turbo-diesel version of this 3.3-litre six will also be available that will produce 187kW/550Nm. 

The CX-60 flagship PHEV model will be able to make 241kW/500Nm, making the CX-60 the most powerful model in Mazda’s current production line.
