Why diesel still makes sense in 2026 (for the right buyer).

Walk into any new-car showroom in 2026 and you'll be steered, gently or otherwise, towards an EV or a hybrid. There's a perfectly good reason for that, most new-car buyers genuinely are better served by electrification. But "most" is not "all", and the used-car market is a fundamentally different conversation. The questions are different. The maths is different. And the diesel that nobody wanted to build a decade ago is suddenly one of the most rationally priced things on a Dutch lot.

Who this article is actually for

If you live in central Amsterdam, drive 8,000 km a year, and have a charging point at home, close this tab. You don't need a diesel and you'll be miserable in one. The buyer this article is for has roughly the opposite profile: rural or semi-rural driver, frequent long-distance trips, a household annual mileage of 25,000 km or more, and either no off-street parking or no easy access to slow charging at home. For that buyer, the picture changes completely.

The real numbers

Modern Euro 6d diesels, anything from roughly 2019 onwards, return 4.5 to 5.5 L/100km on real-world long-distance driving. At today's average pump price in the Netherlands, that's around €0.08 to €0.10 per kilometre in fuel. A petrol equivalent of the same size and power costs €0.12 to €0.14. An EV charging exclusively at public fast chargers (which our target buyer often has to do) is currently sitting between €0.10 and €0.16 per km, depending on operator.

Cheaper home charging completely flips that picture, but home charging is only available to drivers who, by definition, are not the buyer this article is talking about.

The depreciation gift

Used diesel is currently undervalued, by which I mean, the market has priced it as if it were dying faster than it actually is. A 2020 Volkswagen Passat 2.0 TDI with 90,000 km that would have cost €19,000 in 2022 now changes hands at €13,500 to €14,500. A petrol equivalent has held value much better; an EV equivalent has often lost more, but starts from a higher number.

That depreciation gift is a one-time event for the second owner. The diesel has already taken its hit. As long as it stays mechanically healthy and the regulatory environment doesn't change drastically, the next five years of value loss will be much milder than the previous three.

What about low-emission zones?

This is the question every diesel buyer asks, and it deserves a careful answer. Euro 6 diesels are not affected by Dutch milieuzones. Every major Dutch city's milieuzone applies to Euro 5 and older diesel passenger cars; Euro 6 (sold from roughly 2015) and Euro 6d (from 2019) are explicitly permitted, with no current proposals to change that for passenger vehicles before 2030.

If you regularly drive into Amsterdam, Rotterdam, Den Haag or Utrecht city centres, simply make sure the car you're buying has Euro 6, and ideally Euro 6d-temp or Euro 6d, both of which have far better real-world emissions than earlier Euro 6 implementations.

The right used diesel today is what the right used petrol was a decade ago: undervalued by the market, mechanically mature, and quietly the most economical way to do serious mileage.

What to actually buy

Not every diesel ages well. The ones we look for, and the ones we keep on our lot, share a few characteristics:

• 2.0-litre, four-cylinder, modern common-rail. The sweet spot of efficiency and longevity. Avoid the early small-displacement diesels (1.4 / 1.5), too stressed for sustained motorway use.
• Manual transmission, or a known-good automatic. VW DSG, ZF 8HP, Aisin TF-80SC, these auto boxes are excellent. Cheap dual-clutches in compact models, often less so.
• Documented motorway-heavy history. A short-trip diesel will eventually clog its DPF. We won't take one in trade unless we can verify highway use.
• Service history with diesel-specific care. Regular DPF regeneration, EGR cleaning, and fuel filter changes. These aren't expensive, but they have to be done.

The bottom line

Diesel isn't dead. Diesel for short-range urban drivers is dead, that's a different sentence. For the high-mileage, mostly-motorway driver who can't easily charge at home, a well-chosen Euro 6d diesel from 2019 onwards remains, in pure euros-per-kilometre and total cost of ownership, the most rational car money can buy in 2026.

That window will close. By 2028 the used-EV market will likely have matured to the point where the maths shifts again. But for now, and this is the entire point of this article, the data is on our side, and the prices are too. If you're the buyer this article was written for, take a look at the cars on our lot before you write off the option.
