New six-cylinder flagship SUV will be more efficient than its four-cylinder stablemates when it arrives in August
Mazda Australia has released fuel consumption and CO2 emission figures for the upcoming 2023 Mazda CX-90 ahead of its local release in August.
Like the new 2023 Mazda CX-60 medium SUV due to arrive in June, the all-new large seven-seat flagship SUV will be available in both turbocharged six-cylinder petrol and diesel guises.
And it shouldn’t come as much of a surprise to find it’s the latter – a 3.3-litre straight-six oil-burner that outputs 187kW/500Nm – that will be the more frugal powertrain, with combined consumption of 5.3L/100km, while CO2 emissions are officially pegged at 143g/km.
The CX-90’s 3.3-litre turbo-petrol straight six, meanwhile, will drink a claimed 8.2L/100km on the combined cycle and emit 189g/km – not bad given it’s the brand’s punchiest powertrain to date with 254kW/550Nm.
That results in a 6.9-second 0-100km/h time and, for comparison’s sake, the diesel stops the clock in 8.4sec.
For reference, the smaller and lighter CX-60 is more efficient, with the diesel consuming 4.9L/100km and emitting 128g/km and the petrol arriving with figures of 7.4L/100km and 171g/km respectively.
But despite the fact it comes with bigger six-cylinder engines, Mazda new flagship SUV will be more economical than both the CX-8 and CX-9 four-cylinder seven-seaters it will eventually replace.
The 2.2-litre turbo-diesel CX-8 consumes 6.0L/100km (2.5L petrol: 8.1L/100km), while the 2.5-litre turbo-petrol engine in the CX-9 consumes 9.0L/100km.
A 2.5-litre plug-in hybrid system will also join the CX-90 fray sometime next year and it will almost certainly obliterate the consumption and emission numbers of both internal combustion mills, given the CX-60 PHEV is claimed to consume just 2.1L/100km.
With this in mind, we expect the CX-90 PHEV to sip about 2.5L/100km and to have a marginally shorter all-electric driving range.
Both the petrol and diesel engines are mated to an eight-speed automatic transmission driving all four wheels as standard.
“Mazda has an established reputation for pushing the envelope and achieving complex engineering goals in pursuit of driving pleasure,” Mazda Australia managing director Vinesh Bhindi said.
“These two fully engaging, high-performance powerplants make considerable advancements, not only in power and performance, but also in overall efficiency, ensuring that the signature ‘Jinba Ittai’ Mazda driving experience delivers involvement and fun without any expense to frugality.”
Full pricing and specification details for the CX-90 will be announced in the coming weeks.
