One of Volkswagen’s most extraordinary engineering experiments is back on the market. A virtually unused Volkswagen XL1, the futuristic diesel plug-in hybrid designed to consume just 0.9 liters per 100 kilometers, is being auctioned in the Netherlands.
But behind its €110,000–€125,000 estimate lies an intriguing question: was this very car sold for less than €30,000 just seven months ago?
The white XL1, built in 2015 and first registered in Luxembourg in March 2016, has covered just 1,672 kilometers. It is offered through Catawiki, the Dutch online auction platform specializing in collectibles and classic cars, with bidding closing on 12 November.
By Tuesday morning, bidding had reached €70,000 after 51 bids, although the seller’s reserve price had not been met. Interestingly, the auction also offered a Buy Now option at €107,251, below Catawiki’s own estimated value of €110,000–€125,000.
However, an apparently identical XL1 appeared at Bonhams’ Monaco auction on 24 April 2026. Also white and first registered in Luxembourg in March 2016, it had covered 1,426 kilometers and sold for just €29,900, including the buyer’s premium.
If the chassis numbers match, the car has traveled only 246 kilometers between auctions, while its estimated value has almost quadrupled. Newmobility.news has asked Catawiki to confirm the VIN and clarify its recent ownership history.
From Luxembourg to the Netherlands
Bonhams identified its car as chassis WVWZZZ11ZFK000074, manufactured in Dresden in 2015 and delivered through Luxembourg importer Losch. It was used for promotional activities by the energy technology company INGEM before changing hands in 2019.
The Catawiki example has recently been imported into the Netherlands, registered and serviced. Whether its current owner bought it in Monaco remains unclear. Catawiki identifies the vendor as a Netherlands-based private seller but does not disclose the reason for selling.
The valuation gap is striking, although an estimate is not a realized price. Another XL1 fetched €97,750 at Bonhams Paris in 2022, illustrating the volatility of this tiny collector market.
Ferdinand Piëch’s one-liter obsession
The XL1 was the culmination of Ferdinand Piëch’s ambition to build a car capable of traveling 100 kilometers on a single liter of fuel. But Volkswagen’s pursuit of extreme efficiency had begun decades earlier.
In 1986, it unveiled the three-wheeled, Polo-based Scooter concept at Geneva, a lightweight two-seater with gullwing doors that never entered production. In 1999, the Lupo 3L TDI became the world’s first production car to officially consume less than 3 liters of diesel per 100 kilometers.
The XL1 took that philosophy to its ultimate extreme. When the production-ready version debuted at the 2013 Geneva Motor Show,
Volkswagen invited selected journalists to drive it from Lucerne to Geneva. Among the guests was Austrian skydiver Felix Baumgartner, famous for his record-breaking jump from the stratosphere.
Volkswagen ultimately built just 250 XL1s, including 200 intended for customers. Its engineers pursued efficiency almost without compromise: a carbon-fiber body, enclosed rear wheels, butterfly doors and camera-based mirrors achieved an exceptionally low drag coefficient of 0.19.
Weighing just 795 kilograms, the two-seater combined a 0.8-liter, 48 hp, two-cylinder diesel engine with a 27 hp electric motor and a seven-speed DSG gearbox. Combined output was 68 hp, with a top speed limited to 160 km/h.
A 5.5 kWh battery enabled up to 50 kilometers of electric driving. The official NEDC figure of 0.9 liters per 100 kilometers, equivalent to 21 g/km of CO₂, relied on a charged battery and external electricity. It did not mean the XL1 could indefinitely cover 100 kilometers on one liter of diesel.
An exceptionally rare sight in Belgium
Six XL1s reportedly reached the Netherlands, while Belgium has at least two documented examples in collections. One belongs to the D’Ieteren Gallery, the Belgian Volkswagen importer’s historical collection, and has been driven on public roads by automotive journalists.
Original buyers were carefully selected. Among them was German entrepreneur Wolfgang Grupp, who reportedly ordered two XL1s for his children.
Despite its engineering brilliance, the XL1 ultimately became a technological dead end. Its carbon-fiber construction and specialized diesel-electric drivetrain were too expensive and complex for mass production. Volkswagen instead moved towards conventional plug-in hybrids and, eventually, its fully electric ID. family.
Yet the XL1 remains a fascinating reminder of an era when carmakers competed to make vehicles consume less rather than accelerate faster.
Whether collectors now consider that ambition worth €125,000 is another question. The Catawiki auction closes on Thursday, 12 November. Its final price — and confirmation of the car’s identity — may prove almost as interesting as the vehicle itself.
