Since 2005, the Arosa ClassicCar has been offering drivers and spectators alike a fascinating classic car festival in the Grisons mountains. The focus is on the 7.3-kilometre race route from Langwies to Arosa. It includes 76 bends and climbs 422 meters in altitude. Another special feature is a 1.2-kilometer downhill section. The combination of technical riding challenges, alpine scenery and proximity to the public makes this event unique.
Motorsport and classic fascination
With around 180 vehicles, this year's event impressively showcased the full diversity of classic motorsport - and much more besides. This year, Arosa provided an impressive "demonstration" of how changeable the weather in the mountains can be in the transitional period between summer and fall: Friday provided a wintry start with hail and snowfall, which even resulted in a snow clearing vehicle driving through the tent city of the pit area. Downpours left some drivers walking barefoot or in Crocs through the paddock. But the capricious weather soon ran out of steam. By Friday evening, Arosa was already showing its best side again and the sun was shining through.
This provided ideal conditions for the races. Thomas Amweg secured the Arosa Grand Prix in his Amweg F2 AW 76 Monoposto with the fastest track time of 4:12 minutes. He also won the Competition Formula category. The other classes were won by Philipp Brühwiler in a Chevron B8 GT (Competition), Til Alpstäg in his Porsche 911 T (Arosa Classic Trophy) and Leonhard Sven Willi in an Alfa Romeo Giulia TI (Arosa Sport Trophy).
Festival atmosphere along the course
In addition to the races, Arosa also offered a varied supporting program in 2025, as expected. The open paddock offered interesting insights into the technology of the bikes, invited visitors to chat with the riders and food stalls provided refreshments along the route. Meanwhile, the starting area in Langwies was the real meeting point for die-hard fans and those close to the scene throughout the day.
The sold-out Porsche race cab rides were once again a special highlight this year. Passengers were offered an impressive moment from the perspective of all those who took to the track themselves.
Doing what is possible: eFuels in action
Car racing in the mountains, the automotive fringe group having fun for a weekend - to take the wind out of the sails of the critics of such events, the organizers in Arosa did a lot to cultivate sustainability, insofar as this is possible at all. Together with the main sponsor Porsche Switzerland and HIF Global, eFuel was made available - something that is already the case in various championships also proved to be quite practicable in Arosa.
Lots of light and hardly any shade
Arosa can look back on a successful race weekend. The OC is satisfied, but acknowledges certain sticking points. For example, unplanned delays caused longer breaks and frayed the nerves of participants racing against the clock. The length of the route and the colorful mix of serious racers, dedicated amateurs and pure fun riders makes for a tricky balancing act between the different interests in such an event.
However, the proximity to the audience and the special atmosphere stand out in Arosa. "This edition was special in every respect: top-class cars, a strong starting field and an audience that shares the passion," says OC President Markus Markwalder. "The mixture of motorsport, family atmosphere and the unmistakable Arosa flair makes the Arosa ClassicCar unique." Project manager Dario Neuhäusler also draws a positive conclusion: "After the wintry intermezzo on Friday, we were able to experience two great days of racing. My thanks go to the riders, our partners and the great team of helpers."
The 22nd Arosa ClassicCar will take place next year from September 3 to 6, 2026
