2020 Mazda CX-5 Sport D 2.2L Diesel · SK70 WHF

The 2.2-litre Skyactiv-D diesel in the CX-5 is one of the more efficient options in the mid-size SUV class, with real-world fuel economy typically in the 45-55 mpg range for mixed driving. Road tax for a 2020 diesel of this specification usually falls into a moderate VED band, though diesel SUVs above £40,000 new attract the supplementary premium for the first five years from registration.

Insurance for the CX-5 Sport tends to sit in a mid-range group, reasonable for a family-sized SUV. Standard maintenance costs — including oil services, brake fluid, and filters — are typical for the class, with no expensive quirks widely reported for this generation. Diesel-specific items such as AdBlue top-ups and DPF attention should be factored into longer-term budgeting.

Given the entirely clean MOT history with no advisories recorded, there are no specific defect types flagged by the test record to prioritise. Instead, focus general inspection effort on the areas commonly worn on a diesel SUV at this mileage, including brake discs and pads, suspension bushes, and tyre condition.

Open the bonnet and check for any signs of oil leaks around the engine and turbo area, which is worth examining on any diesel of this age. Inspect the DPF (diesel particulate filter) for warning lights on the dashboard, and confirm the AdBlue system is functioning correctly — these are expensive items if neglected.

Finally, examine the bodywork for any panel gaps, signs of accident repair, or mismatched paint, and check that all interior equipment — infotainment, climate control, and driver assistance systems — operates as expected. A pre-purchase inspection by a Mazda specialist or independent garage is recommended.
