Last updated: April 13, 2025 – Based on WLTP consumption data, real-world testing and market availability in the UK and EU.
Despite the rise of hybrids and electrics, diesel SUVs remain a top choice for drivers who need strong towing capacity, long-distance efficiency, and low-end torque. Whether you live in the countryside, drive on motorways, or haul gear every weekend, a diesel SUV can offer the best mix of power, endurance, and fuel economy.
In this guide, we look at the best diesel SUVs to buy in 2025, selected for their real-world performance, value for money, and relevance in the UK, Italy, France, and Spain.
Are diesel SUVs still worth it in 2025?
Yes — especially if you:
- Drive long distances regularly (diesel is still the king of motorway economy)
- Tow trailers, caravans or boats
- Live in rural or mountainous areas where torque and traction matter
- Want low CO₂ emissions per kilometre on the open road
Modern diesels also meet Euro 6d-Final standards, meaning they’re legal in most European LEZ zones and offer impressive efficiency when driven properly.
“In the right use case, diesel remains unbeatable for energy density and range,” says Felix Page, technical editor at Autocar.
Best Diesel SUVs in 2025
1. BMW X3 xDrive20d – Balanced Performance, Refined Efficiency
- Engine: 2.0L 4-cylinder turbo diesel
- Power: 190 hp, 400 Nm
- WLTP consumption: 5.3 L/100 km (53.3 mpg UK)
- Drivetrain: AWD with mild hybrid boost
I drove the X3 xDrive20d from Munich to Calais on a single tank — nearly 900 km — and still had reserve left. The mild hybrid system adds smoothness at low speeds, and the cabin refinement rivals some electric crossovers.
2. Skoda Kodiaq 2.0 TDI 150 DSG – The Practical Choice for Families
- Engine: 2.0 TDI
- Power: 150 hp
- Boot: 835 litres (5-seat mode)
- WLTP: ~5.1–5.7 L/100 km depending on spec
This is a favourite in Italy and Spain, and for good reason: solid reliability, huge space, and class-leading value. I drove one in the Pyrenees last summer — loaded with bikes and luggage — and it didn’t flinch, even on steep gravel paths.

3. Mazda CX-60 3.3L e-Skyactiv D – A Different Kind of Diesel
- Engine: 3.3L inline-six diesel
- Power: 200 hp (RWD) or 254 hp (AWD)
- Mild hybrid: 48V system
- Efficiency: As low as 4.9 L/100 km (57.6 mpg UK)
Mazda has taken a bold step by offering a large-capacity diesel with mild hybrid support. I tested the AWD version in the Alps, and it pulls like a locomotive while averaging sub-6 L/100 km — unheard of for a six-cylinder SUV.

4. Land Rover Defender 110 D250 – For Adventure Without Sacrifice
- Engine: 3.0L 6-cylinder mild hybrid diesel
- Power: 249 hp
- Torque: 600 Nm
- Towing: Up to 3,500 kg
- WLTP: 7.6 L/100 km (37.2 mpg UK)
This isn’t the most frugal SUV, but it’s one of the most capable. I used one for a week-long shoot in the Scottish Highlands and averaged just under 8L/100 km — not bad considering the terrain, load, and pace.
“The Defender might be the most refined off-roader money can buy,” says Henry Catchpole, journalist at Carfection.
5. Peugeot 5008 BlueHDi 130 EAT8 – Seven Seats, Surprising Economy
- Engine: 1.5L BlueHDi
- Power: 130 hp
- WLTP: ~4.7–5.0 L/100 km
- Strength: Light weight, clever space use
If you need seven seats and diesel economy, the 5008 remains a smart buy. I tested it in Normandy with three adults, two kids and luggage — and still managed just under 5 L/100 km. The small engine pulls surprisingly well, and it’s one of the few seven-seaters that feels nimble in town.

What to look for in a diesel SUV in 2025
Based on hundreds of tests, I recommend checking:
- WLTP vs real-world gap – diesels often exceed WLTP on motorways
- Mild hybrid tech – worth it for city start-stop smoothness
- LEZ compliance – check Euro 6d-final status for your region
- Towing + payload – especially if you transport trailers, gear, or dogs
- Weight-to-torque ratio – heavier diesels need more torque to avoid sluggishness

Final Thoughts
In 2025, diesel SUVs are no longer the “default” choice — but for many drivers, they’re still the most logical. If you regularly drive long distances, haul gear or need serious towing capability, diesel makes both economic and practical sense.
For the best mix of power and efficiency, I’d choose the Mazda CX-60 D254 — it’s smooth, powerful and frugal. But for families, the Skoda Kodiaq or Peugeot 5008 offer unbeatable value in real-world conditions.
Diesel might not be future-proof, but in the present, it’s still a hard option to beat.
