2023 Mazda CX-60 diesel six-cylinder engines detailed

The new Mazda CX-60 SUV will be offered with two six-cylinder diesel engines – with or without mild-hybrid technology – offering up to 187kW and 550Nm.

Details of the inline-six diesel engines available with new 2023 Mazda CX-60 medium to large SUV – the first model on Mazda’s new rear-wheel-drive platform – have been confirmed, ahead of the model’s Australian launch in late 2022.

The headline CX-60 engine in Japan – where these details have been published – is Mazda’s new 3.3-litre turbocharged inline six-cylinder diesel engine, available in two forms: a base variant badged ‘e-SkyActiv D’, and one with a 48-volt mild-hybrid system, known as the ‘SkyActiv-D 3.3’.

Outputs for the former are rated at 170kW and 500Nm (from 1500-3000rpm), with the hybridised variant upping it to 187kW and 550Nm (from 1500-2400rpm). It’s unclear if the latter’s outputs include the mild-hybrid system’s 13kW/153Nm boost, which likely only applies for brief, circa-20-second bursts.

The engines send drive to the rear or all four wheels, depending on tune, through an eight-speed automatic transmission with a multi-clutch design similar to a high-end Mercedes-AMG.

Mazda quotes a 0-100km/h time of 7.3 seconds for the mild-hybrid diesel model.

It’s worth nothing the new 3.3-litre six-cylinder diesel engine shares its bore (cylinder diameter) and stroke (how far the piston travels in the cylinder) with Mazda’s current 2.2-litre four-cylinder diesel engine – indicating it’s effectively a four-cylinder with two extra cylinders ‘added on’.

In single-turbo European guise, the 2.2-litre diesel engine develops 129kW and 420Nm. Scaling this up by 50 per cent gives theoretical outputs of 194kW and 630Nm – suggesting the new six-cylinder engine may be somewhat understressed.

A 3.0-litre ‘SkyActiv-X’ inline-six petrol engine will be available in markets including Europe (but not Japan), though details for this are yet to be confirmed.

Leading the electrified range will be a plug-in hybrid model, pairing a 2.5-litre ‘SkyActiv-G’ non-turbo four-cylinder petrol engine with an electric motor, 17.8kWh battery and all-wheel drive for 241kW/500Nm combined outputs in Europe, or 238kW/500Nm in Japan.

The 2.5-litre petrol engine will be available without plug-in hybrid technology in Japan, with outputs of 138kW and 250Nm – 2kW/2Nm down on the same engine in the CX-5 mid-size SUV, albeit rotated by 90 degrees.

Mazda Australia is yet to confirm which engines will be available in the CX-60 locally after local showroom arrivals begin late in the second half of 2022, however the plug-in hybrid will be one of them – if not necessarily at launch.
