Mazda CX-60 review - MPG, CO2 and running costs
Competitive pricing, hybrid efficiency and solid residual values mean the CX-60 is reasonably cheap to run, although insurance premiums could be expensive
Buyers have the option of two very different engines for the CX-60 – a 2.5-litre petrol plug-in hybrid and a 3.3-litre diesel unit with mild-hybrid technology. While the PHEV makes more sense in an increasingly electrified market, the big oil-burner is perhaps more of an oddity.
The 197bhp diesel is able to return an impressive 56.5mpg on the WLTP combined cycle, while the more powerful 250bhp version delivers 53.3mpg. However, CO2 emissions of 129 to 139g/km aren’t as noteworthy and won’t be of much interest to company car drivers.
Mazda claims the plug-in hybrid CX-60 can cover up to 39 miles on battery power alone, however we’ve been getting closer to 35 miles of range from our CX-60 PHEV long-term test car. Similarly, the Japanese carmaker says its first plug-in hybrid will return up to 188.3mpg, however our average fuel economy while living with the CX-60 PHEV has been between 40-50mpg.
We did see a more impressive 70mpg on one trip when the 2.1-tonne SUV was full of passengers and luggage, however that’s still a long way off Mazda’s claimed figures.
At least the CX-60 PHEV’s CO2 emissions of 33g/km equates to a very low 8 per cent Benefit-in-Kind tax rate at the moment, compared to 30-32 per cent for the diesels. Keeping the plug-in CX-60’s 17.8kWh battery topped up shouldn’t be too onerous a task, because recharging from 20 to 80 per cent takes just 1.5 hours from a typical 7kW home wallbox charger.
Insurance groups
While the CX-60’s fuel economy is impressive, insurance costs will be less so. The plug-in hybrid model sits in either group 38 or 39, depending on your chosen trim level, which means premiums will be expensive. The 197bhp diesel in Exclusive-Line trim is the cheapest version to insure as this sits in group 33.
Depreciation
The CX-60 plug-in hybrid is the strongest model in the range for holding onto its value. After a typical three-year/36,000-mile ownership period, the PHEV should retain around 46 per cent of its original showroom price, while the 3.3-litre diesel (in either 197bhp or 250bhp form) ranges from 35-39 per cent - with the top-spec Takumi versions faring the worst.
