The used mid-size SUV market is one of the most competitive spaces in UK motoring. Plenty of cars look good on paper — sensible running costs, proper family room, a high driving position — but few deliver on all fronts without compromise. The Hyundai Tucson and the Mazda CX-5 are two that regularly top used-car shortlists, and for good reason. Whether you're drawn to Hyundai's generous standard kit or Mazda's reputation for driver satisfaction and cabin quality, there's a strong case for each. This comparison cuts through the noise on the Hyundai Tucson vs Mazda CX-5 question and tells you which one is the better used buy in 2026.

For context: the third-generation Tucson (known as the TL) ran from 2015 to 2020, with a mild facelift in 2018. It was replaced by the significantly redesigned NX4 Tucson from 2021. The Mazda CX-5 Mk2 arrived in 2017 and has been a continuous, relatively unchanged presence ever since — testament to just how well-sorted it was at launch. Both have strong dealer networks, a wide spread of used stock across the UK, and trim levels to suit most budgets.

Hyundai Tucson vs Mazda CX-5: price and used market value

The Tucson is the better-value entry point. On the current UK used market, a 2018 Tucson SE Nav with sensible mileage — around 70,000 to 80,000 miles — will cost you £7,500–£8,500. Move to a 2020 Premium SE trim with the 1.6 T-GDi turbo petrol and a full service history, and you're looking at £11,000–£13,000. The 2021-onwards NX4 Tucson, with its bold new styling and available mild-hybrid powertrains, is priced from around £15,000 for early examples and climbs to £22,000 for well-specified 2023 cars.

The Mazda CX-5 commands a noticeable premium. A 2019 CX-5 Sport Nav+ diesel with around 70,000 miles starts at £10,400–£11,700 based on current listings. A 2020 or 2021 car with a clean history sits at £14,000–£18,000, and a late 2022 or 2023 GT Sport Tech — Mazda's flagship trim — can approach £25,000. The CX-5 holds its value better than the Tucson, which works against you as a buyer but is worth remembering if you plan to sell in two or three years. Neither car depreciates catastrophically, but the Mazda's resale curve is noticeably flatter.

Reliability: which used mid-size SUV is more dependable?

Reliability is where these two cars show genuinely different characters. The Mazda CX-5 has one of the strongest reliability records in the segment. The SKYACTIV engines — both petrol and diesel — are mechanically uncomplicated by modern standards, and Mazda's philosophy of incremental improvement over radical reinvention means the Mk2 was well-sorted from the start. Known issues are minor: some early 2017 examples had infotainment software glitches, and the 2.2 SKYACTIV-D diesel can exhibit DPF issues if used predominantly on short runs — common to virtually every modern diesel. Overall, the CX-5 is among the most dependable cars in its class.

The Tucson's record is solid without being exceptional. The 1.7 CRDi diesel is the pick for reliability — it's smooth, proven, and relatively unfussy. The 1.6 T-GDi petrol turbo has occasionally suffered from oil consumption issues on higher-mileage examples, so check the service history closely and look for evidence of regular oil changes on any car above 60,000 miles. Owners have also reported some infotainment touchscreen failures on pre-facelift 2015–2017 models, and electric parking brake modules have been known to play up on Sport variants. None of these issues are expensive to fix, but they're worth knowing about when inspecting a used car. The newer NX4 Tucson, being younger, has fewer reported issues on the whole, though it's still early days for long-term reliability data on the 48V mild-hybrid system.

Practicality: boot space, cabin room, and family life

On paper, the two cars are nearly identical for space. The Tucson offers 513 litres of boot space with the rear seats up, while the CX-5 provides 506 litres — a difference you'd never notice in practice. Both fold their rear seats flat, and both offer comfortable room for three adults across the back seat, though taller passengers will find the Tucson marginally more generous for rear headroom thanks to its slightly squarer roofline.

Where the Tucson pulls ahead in day-to-day family use is storage. The cabin has abundant cubby holes, a large glovebox, and wide door bins. The NX4 generation takes this further with a full-width shelf under the infotainment screen. The CX-5 is more restrained — Mazda prioritised a clean, uncluttered aesthetic, which means there are fewer places to stash drinks bottles, sunglasses, and the assorted detritus of family motoring. It's not a dealbreaker, but it's a genuine practical difference.

Both cars are available with four-wheel drive, which matters if you're buying in Scotland, rural Wales, or anywhere that sees real winters. The Tucson's 4WD system — known as HTRAC on later models — is well-regarded and available on diesel variants from SE Sport trim upwards. The CX-5 offers i-ACTIV AWD, which is similarly effective and has a strong reputation among owners for smoothly distributing torque in slippery conditions. If you need AWD, budget an extra £1,000–£2,000 on the used market for either car.

Hyundai Tucson vs Mazda CX-5: driving experience

This is where the two cars part ways most sharply — and where your personality as a driver will decide the winner. The Mazda CX-5 is genuinely enjoyable to drive. The steering is accurate and weighted well for a family SUV, the chassis communicates what the front wheels are doing without being fidgety, and the ride quality on UK roads is controlled without ever feeling harsh. The 2.2-litre diesel is the engine to choose: 150–175bhp depending on specification, strong torque from low revs, and well-matched to both the manual and automatic gearboxes. The petrol 2.0 is adequate but feels a little breathless under load. In a class where most cars feel like appliances, the CX-5 feels considered.

The Tucson is competent and composed, but it doesn't excite. Ride quality is slightly softer — welcome on school-run duties and long motorway cruises — and the steering is accurate if somewhat light. The 1.6 T-GDi turbo petrol has a lively low-end response that makes it feel more willing than the power figure suggests, while the 2.0 CRDi diesel is relaxed at motorway speeds. The NX4 Tucson, with its new platform, feels more polished than the outgoing TL: the ride-handling balance is better, and cabin noise at speed is noticeably lower. But neither generation will make a driver's pulse quicken. The Tucson is excellent transport; the CX-5 is a car you might actually look forward to driving.

Running costs: fuel economy, servicing, and road tax

Both cars offer similar real-world fuel economy in diesel form: expect 40–48mpg in mixed driving from either the Tucson 1.7 CRDi or the Mazda 2.2 SKYACTIV-D. The Mazda's official figure edges ahead at up to 56mpg, and in practice it tends to be slightly more efficient on longer runs — likely down to the CX-5's more aerodynamically slippery shape and the refinement of the SKYACTIV engine. Petrol variants of both cars return 30–38mpg in real-world use; the Tucson's 1.6 T-GDi is fractionally better on motorways than Mazda's 2.0 SKYACTIV-G.

Servicing costs are broadly comparable. Both cars use a 12-month or 12,500-mile service interval, and dealer costs are in the £180–£300 range depending on the type of service. Independent specialists are readily available for both makes. Hyundai's parts tend to come in slightly cheaper than Mazda equivalents, which can make a difference over five years of ownership. Road tax (VED) for cars registered after April 2017 is a flat £195 per year for standard-rate petrol and diesel variants — with some very early TL Tucson diesels potentially falling under the older emissions-based system. Check the V5C registration date before buying.

One cost advantage the Tucson holds is Hyundai's five-year warranty on all new cars from 2016 onwards. A 2019 or 2020 Tucson with its original owner could still have residual manufacturer warranty — always worth confirming with a Hyundai dealer. Mazda has since extended its warranty to five years on new cars, but CX-5s registered before 2021 came with three years as standard. For a used buyer, this matters: a car within its factory warranty gives you a safety net that independently-warranted cars don't provide.

Technology and safety

The Tucson wins the technology contest by some margin, particularly from SE Nav specification onwards. A 2018 or later Tucson SE Nav will typically include a 7-inch touchscreen with Apple CarPlay and Android Auto, rear-view camera, lane-keeping assist, blind-spot monitoring, and automatic emergency braking as standard. Premium SE adds ventilated front seats and a heated steering wheel — a genuinely useful feature on a British winter morning. The NX4 Tucson from 2021 upped the ante significantly with a 10.25-inch digital driver display, a 10.25-inch touchscreen, and an impressive safety package including junction-turning assist and rear cross-traffic collision avoidance.

The CX-5 is well-equipped but more conservative in its approach. Mazda's MZD Connect infotainment system — operated via a rotary controller rather than a touchscreen — divides opinion. Fans argue it's safer and more intuitive to use on the move; critics find it dated compared with the tap-and-swipe simplicity of rival systems. Either way, Apple CarPlay wasn't standard on UK CX-5s until the 2019 model year update, so check carefully on earlier examples. The CX-5's active safety kit is thorough: Mazda's i-Activsense suite includes adaptive cruise control, lane-keep assist, and high-beam assist from Sport trim upwards. Both cars earned five stars from Euro NCAP when tested — the Tucson in 2015, the CX-5 in 2017.

Which used mid-size SUV should you buy?

If your budget is £8,000–£12,000, the Tucson is the logical choice. You'll get a sensibly specified 2018 or 2019 car with useful kit, a proven diesel, and the reassurance of Hyundai's five-year warranty potentially still in play. It's an excellent daily driver — comfortable, practical, and cheap to live with. For families who want maximum space and equipment without pushing past £15,000, the NX4 Tucson from 2021 is one of the best-value propositions in the used SUV market right now.

If you can stretch to £12,000–£18,000 and you drive more than 15,000 miles a year — or you simply want to enjoy the commute — the Mazda CX-5 is worth every extra pound. The interior quality genuinely stands out against rivals costing more; the SKYACTIV diesel is an object lesson in how to build a refined, frugal engine; and the car's resale values mean you won't get punished as badly when the time comes to move on. The CX-5 isn't cheap to buy, but it's excellent value across a full ownership cycle.
