Event Details & Location

Zuffengruppe events are always fresh. We are excited to hold Zuffengruppe InterKlassik 9 on the airfield of the Burlington Airport in Burlington, WI. The event is a unique combination of vintage planes and unique vintage German marques making it the largest gathering of vintage German vehicles in the Midwest.

This year we are adding modern German sports cars of each marque and vintage German motorcycles to the display field.

Zuffengruppe is Rain or Shine.

To display, you must be pre-registered in advance.

Zuffengruppe InterKlassik 9
October 4, 2026
10:00AM to 2:00PM
Burlington Municipal Airport (KBUU) – 703 Airport Rd
Burlington, WI

Vintage Porsches (1998 & older) continue to be the anchor marque. Enhancing the experience and in the spirit of Octoberfest, the event expanded in 2024 to include curated classic BMWs, Mercedes Benz, Audis, and Volkswagens (1995 & older). Vintage aircraft display and fly in from early morning through mid-afternoon, weather permitting.

Vintage German cars, modern German sports cars, and vintage German motorcycles will display along the runway where we’ll be front and center to watch planes flying in and taxing into the event. There will be the vintage Porsches you’ve come to expect at Zuffengruppe events (air-cooled and vintage front-engined Porsches) as well as vintage & modern Mercedes Benz, Audi, BMW, and Volkswagen cars and vintage motorcycles on display this year for all to enjoy.

All displaying cars must pre-register and be pre-1995 to display:

Airplane hangars line the entire area, many of which are open displaying private collections and planes, including historic Warbirds.

A limited number of spectators can pre-register for Reserved Spectator Parking to ensure the closest parking.

There are seated conversation areas, tents, a vendor village, and plenty of food at the event to support the drivers, pilots, and spectators. Your food purchases support the fundraising efforts of two local groups. A local non-profit will have a breakfast available, and the Burlington Fire Department will be manning the lunch grill. Two additional lunch food vendors will be joining us to expand the selection of food options. And, yes, the coffee tents will be up and running when you arrive. (heads up: food/drink is cash only)

Please share the event with other German car and motorcycle enthusiasts and collectors.
