Diesel power no longer dominates Spain’s roads. Its market share has fallen sharply. Yet some professional drivers still rely on it to rack up the miles. For them, the mission is simple: go far, go long, and waste no time at the pump. And the story of a Spanish taxi driver who recently surpassed 400,000 kilometers in the same sedan is a prime example.
Behind those numbers sits a diesel-powered sedan used day in and day out as a working tool. The vehicle logs city trips as well as international runs to France and Portugal. The driver is Álvaro Cenis, a taxi operator in Zaragoza, who has been rolling with an eighth-generation Volkswagen Passat TDI since 2019. With more than 400,000 kilometers on the clock, his experience speaks for itself. It shows what a modern diesel can still offer to those who live on the road.

At first, Álvaro Cenis used his sedan only for half‑day shifts behind the wheel. Then his business grew. He ended up running his Passat TDI full‑time, surpassing 100,000 kilometers in some years. He sums up his reasoning in one line: “Diesel is still economical and reliable for long trips.” That’s how Álvaro Cenis explains it in an interview with the Heraldo newspaper. His assignments go far beyond the typical airport or train-station runs. Bordeaux, Paris or Lisbon appear on his dashboard, with heavy highway work.
With this heavy use, the big sedan has mostly seen routine maintenance. The shop has replaced a turbocharger and carried out a few sporadic repairs. But no major breakdown has interrupted service despite the mileage. “He’s the mileage champion, an economical and reliable diesel,” sums up Álvaro Cenis. “If you drop it into the Ebro, it pops back out on the other side without a problem.” Those words capture the trust he places in his car. He bought this Volkswagen Passat when it had 10,000 kilometers on the odometer, for €21,000 at a dealer in Badajoz. His objective is clear: push it for another roughly 200,000 kilometers before replacing it. For the future, he envisions a diesel Mercedes‑Benz V‑Class or a Skoda Superb TDI around €50,000.

On the highway, this full‑size cruiser is in its element. Álvaro Cenis says it consumes less than 4.5 liters per 100 kilometers under normal conditions. He says he’s even dropped to 3.7 liters while chasing the absolute minimum. “The best part is the range, which runs around 1,200 kilometers on a single tank,” the taxi driver explains. He highlights this, contrasting it with the energy use of current electric cars. For him, the latter must stop far more frequently to recharge. For a professional who makes back‑and‑forth runs between Zaragoza, Bordeaux, Paris or Lisbon, that freedom matters. It weighs heavily in planning his workdays.
This story unfolds just as diesel is retreating noticeably on Spain’s market. According to the vehicle makers’ association ANFAC, diesel accounts for only 16.6% of new car sales in Spain. Over the course of a year, that share fell by 6.2 percentage points, while hybrids reached 39% of the market. Many manufacturers have refocused their lineups toward gasoline electrification, hybrid and electric models, reducing diesel options. Fuel has also become a sensitive point for these professionals. In Spain, a liter of diesel hovers around €1,906 per liter, versus €1,727 per liter for gasoline. A government subsidy of €0.20 per liter remains in place, not erasing the price gap. Filling a 50‑liter tank costs roughly €95 in diesel and €86 in gasoline. “Profitability is tighter because of rising prices,” acknowledges Álvaro Cenis. He does not see himself switching to electric, which he deems too burdensome due to planned recharging. The classic hybrid doesn’t appeal either, as he believes such a powertrain can consume more on long stretches of highway. For now, Álvaro Cenis prefers to stay loyal to diesel to keep his Zaragoza taxi rolling.
