The new 3.3-litre, six-cylinder diesel version of Mazda’s flagship CX-60 SUV will arrive in the UK next year with prices starting at just under £43,000. The new powertrain sits alongside the existing plug-in hybrid in the CX-60 range, providing more long-range efficiency and towing capacity.

The new straight-six mild-hybrid engine is available across the CX-60 range, and will be available with a choice of two power outputs. The basic option, priced from £42,995, is the rear-wheel-drive, 197 bhp engine, while there’s also a 251 bhp version with all-wheel drive that starts at £45,630.

For customers choosing the less powerful option, the only trim level on offer will be the basic Exclusive Line, but the more powerful version is also offered with the more upmarket Homura and Takumi trims, which start at £48,380 and £50,730 respectively.

However, choosing the basic model allows the diesel CX-60 to return 56.5 mpg on the official economy test, while also managing 129 g/km CO2 emissions. The all-wheel-drive, 251 bhp version cuts that economy slightly to 53.3 mpg, while emissions increase slightly to 137 g/km.

That said, Mazda has said efficiency is not the sole aim of the diesel CX-60, claiming it has done a lot of work on refinement. The engine is also designed to give the Mazda enough poke to tow a 2.5-tonne braked trailer. And the 3.3-litre diesel engine will also be joined by a new 3.0-litre straight-six petrol engine in the future, although giving customers a full choice of petrol, diesel and plug-in hybrid tech.

The managing director of Mazda Motors UK, Jeremy Thomson, said the new diesel engine would be best suited to customers who tow or regularly drive long distances.

“Another demonstration of Mazda’s ‘multi-solution approach’, the new diesel is designed to meet the needs of customers who want an efficient, long distance driving car with great towing capacity,” he said. “The company’s multi-solution strategy offers different products and technologies – including more efficient internal combustion engines and a wide range of electrified powertrains, that best suit the local market and society’s demand for sustainability.

“While the PHEV will be the biggest selling CX-60 in the UK, the new six-cylinder diesel is a fantastic example of Mazda’s long-standing reputation for engine innovation and it will be a superb choice for many retail customers looking for a high-quality large premium SUV with a clean and efficient diesel engine.”
