Why a big diesel still makes sense for long road trips across Europe
Autocar's writer describes a six-day, 2,000-mile drive in a Mercedes E450D, arguing that large diesels still suit long journeys.
According to Autocar, a writer covered roughly 2,000 miles in six days in a Mercedes E450D diesel. The journey began with a crossing on LeShuttle, the car-carrying train that runs through the Channel Tunnel, and the writer was heading into France when the account begins.
The piece frames the trip as a test of what a large diesel does best: covering long distances with fewer stops and a generous amount of luggage or passengers. The writer says a single full tank was enough to reach a point 790 miles to the north, a figure offered as part of a personal account rather than a formal test.
Autocar also points out that Audi and BMW have stopped selling large diesel estates in the UK. The writer treats this as a sign of changing buyer habits and manufacturer priorities, while acknowledging that Britain is a small island where most drives are short. The argument is that a few long trips each year are exactly the situation a big diesel was built for.
The report is an opinion-led travel diary rather than a news event with official statements or company responses. Its tone is conversational, and its main contribution is a view of why some drivers still value a diesel that prioritizes range and comfort over the newest technology.
Background
Diesel engines have long been valued for their fuel efficiency and strong low-speed pulling power, which made them popular for motorway driving, towing and high-mileage fleet use. In Europe and the UK, diesel estates and large saloons were once common choices for families, sales reps and anyone who drove long distances as a matter of routine.
That popularity began to shift as governments tightened rules on pollution, particularly nitrogen oxides and fine particulates. Newer emissions standards required more expensive exhaust treatment, and cities began introducing low-emission zones and charges that target older or higher-emitting vehicles. Many buyers responded by moving to petrol, hybrid or fully electric models, and manufacturers gradually reduced their diesel ranges.
Cross-Channel travel has its own traditions. The Channel Tunnel allows drivers to take their own cars between Folkestone and Calais by train, which has made road trips through France, Belgium, Germany and beyond a familiar option for British motorists. Long drives like these reward cars with comfortable seats, good stability at speed and enough range to limit refueling stops.
Large diesels remain widely used in some markets and sectors, but their future in the UK new-car market has narrowed. Used examples can still appeal to drivers who want strong torque and long range at a lower purchase price, though the rules that apply to older diesels in certain cities are an important consideration for any buyer.
Why it matters
The story touches a question many drivers are quietly asking: does the car you buy need to match the way you actually use it? For most people, daily driving is short and local, and electric or small petrol cars suit that pattern well. Yet a smaller group regularly covers long distances, carries heavy loads or travels to places where charging infrastructure is less dependable, and for them the trade-offs look different.
When manufacturers stop selling a category, they also narrow choice. If large diesel estates disappear from new-car showrooms, buyers who need that combination of range and load capacity must turn to used cars, fleet sales or a different body style. That shift can affect prices, the availability of spare parts over time and the simple question of which vehicles are still on offer.
The article also reflects a wider tension in the car industry between the environmental goals behind emissions rules and the practical needs of drivers who rely on their vehicles. Both sides have legitimate points, and stories like this one bring the human side of that debate into focus without requiring any particular conclusion.
Finally, the piece shows how motoring coverage can blend personal experience with broader trends. A single writer's journey becomes a way to ask what cars are for, who they serve and what gets lost when a whole category fades from the market.
What to watch
Watch for whether other manufacturers continue to reduce their diesel line-ups or keep certain models available for fleet and commercial buyers. Decisions like these often signal how long a segment will remain viable for private customers.
Keep an eye on local emissions rules, particularly low-emission zones and vehicle charges in UK cities and parts of Europe. Changes to these policies can shape the resale value and practical usefulness of existing diesel cars.
Look also at the used market. If demand for large diesels stays steady among long-distance drivers, prices and availability may tell a different story from the new-car showroom.
Finally, consider how charging networks and long-range electric models develop. Their progress will determine how many drivers can make long journeys without choosing a diesel at all.
Viewpoints
Commentary from our columns: three angles on this story.
The Driver's Seat the enthusiast's take
There is something quietly satisfying about a car that was built to cover ground without fuss. A big diesel with a comfortable seat, a steady engine and a full tank can turn a long motorway run into a rhythm rather than a chore. Anyone who has spent hours behind the wheel knows that the best long-distance car is the one you forget about after the first hour.
Enthusiasts often chase lap times and sharp handling, and those things matter. But there is a different kind of driving pleasure in the relaxed miles, the easy overtakes and the feeling that the car will simply keep going. The writer's account captures that feeling well, and it is a reminder that a car's character is not only about how it corners.
It is easy to dismiss the diesel estate as a relic, yet it earned its place for good reasons. Stories like this one remind us that motoring culture is broader than the latest headline technology. Some of the best cars are the ones that just do the job, mile after mile, without asking for much attention in return.
The Accountant price, value and running costs
Long journeys tend to expose the real cost of ownership. When a car is used for thousands of miles in a short period, fuel economy, tyre wear, servicing and depreciation all add up. A diesel with strong range can reduce refueling stops, which many drivers value, but the total picture depends on purchase price, maintenance and how the car holds its value over time.
The bigger question for anyone considering a large diesel now is resale. When manufacturers stop selling a model in a market, used values can move in unexpected ways. Some buyers find a bargain, while others discover that running costs or local charges reduce the savings. Checking local rules and total ownership costs before committing is wise.
This is not an argument against diesel. It is a reminder that the cheapest option on paper is not always the cheapest in practice. Careful arithmetic, not nostalgia alone, should guide the decision, especially when a car will be used far from home.
The Commuter the everyday buyer's view
Most of us do not drive 2,000 miles in six days. For the daily commute, school run and weekend shop, a smaller car is usually the sensible choice, and the question of big diesels can feel far away. Yet many households do need occasional long journeys, moving house, visiting relatives or carrying bulky items, and a car that handles those trips well still matters.
The shift away from large diesels may leave some everyday buyers wondering what to choose. An estate or large saloon can be useful, but it may not suit crowded city streets or short hops to the shops. Finding a balance between daily convenience and the odd long drive is the real challenge for many people.
Ultimately, the best car is the one that fits your real life, not the one you imagine using once a year. Reading about enthusiasts crossing Europe is enjoyable, but the everyday buyer still has to ask what they really need from a car.
