• Up to 50mpg (diesel)
• 36-mile EV range (PHEV)
• High purchase price

What are the running costs?

Diesel CX-80s are the cheapest to run if you do long distances. Mazda claims up to 50mpg and CO2 emissions of 150g/km – impressive for a big SUV. Expect 40-45mpg in mixed driving.

The plug-in hybrid emits as little as 33g/km of CO2 and offers 36 miles of electric-only range. It’s a great company car option thanks to low Benefit-in-Kind tax, but not as efficient as it looks if you can’t charge it regularly.

Mazda claims 36 miles of electric driving range. In reality, you might get close to this on a gentle A- or B-road run. But it trails the Skoda Kodiaq plug-in hybrid, which managed 63 miles in our testing. Charging is via a Type 2 connector with a 7.2kW onboard charger – expect a full charge in a couple of hours.

Servicing and warranty

From September 2025 Mazda’s standard warranty covers six years or 100,000 miles, with the battery and hybrid system covered for eight years or 100,000 miles. There’s a wide UK dealer network and service plans are available.

The CX-80 should be affordable to maintain, with long service intervals and no expensive extras required. Mazda also has a solid reputation for build quality and reliability.

Reliability

• New platform, but proven bits
• Diesel used in CX-60
• Mazda’s solid record

It’s too early to judge the CX-80’s reliability in full, but the signs are positive. The diesel engine has already proven itself in the CX-60 and seems durable. Mazda’s engineering is typically robust and its dealer support is generally well regarded.

That said, the hybrid system could prove more complex and may be worth avoiding for long-term ownership.
