Klaus Abbelen, born on 15 September 1960, is a German businessman and former racing driver who built his motorsport career around the endurance racing events held at the Nürburgring. He began competing seriously in 1999 and made his first attempt at the 24 Hours of Nürburgring in 2002. Abbelen owns Abbelen GmbH, a producer of Frikadellen, and the family business provided both the team name and a measure of financial backing for the racing operation.
Sabine Schmitz, a celebrated German racing driver known internationally for her mastery of the Nürburgring Nordschleife, co-founded the team with Abbelen. She remained a central figure in the team's operations until her death in 2021. Her connection to the Nordschleife — she was one of very few women to win the 24 Hours of Nürburgring outright — gave Frikadelli Racing an identity closely tied to the circuit and its culture.
Frikadelli Racing developed into a consistent presence in the Nürburgring Langstrecken-Serie (NLS), the endurance championship contested on the full Nordschleife layout. The team entered the NLS across multiple seasons, competing primarily in Porsche machinery in its earlier years before later transitioning to Ferrari GT3 cars.
Abbelen himself was a regular driver for the team throughout its history, frequently combining roles as team principal and competing driver. He participated in the 24 Hours of Daytona in 2016, racing alongside Patrick Huisman, Sven Müller, Frank Stippler, and Sabine Schmitz, the crew finishing twelfth in the GTD class, demonstrating the team's broader ambitions beyond the Nordschleife.
The defining moment in Frikadelli Racing's history came at the 2023 24 Hours of Nürburgring. The team entered a Ferrari 296 GT3, driven by Earl Bamber, Nicky Catsburg, Felipe Fernández Laser, and David Pittard. The car took an outright victory in the race — a result of historic significance on multiple levels.
It was the first overall victory at the 24 Hours of Nürburgring for Ferrari as a manufacturer. It was also the first victory for a non-German manufacturer at the event since 2002, when Zakspeed won with a Chrysler Viper GTS-R. The win underlined the competitiveness of the Ferrari 296 GT3 in its early competitive seasons and validated Frikadelli Racing's standing as a serious contender at the highest level of Nürburgring endurance competition.
Frikadelli Racing holds a distinctive place in the culture of Nürburgring endurance racing. The team grew from a privately-funded family operation into an outfit capable of winning one of the world's most demanding and prestigious endurance events. Its identity — rooted in regional pride, the legacy of Sabine Schmitz, and years of accumulated Nordschleife experience — made it popular among the large and passionate fan base that the 24 Hours of Nürburgring attracts each year.
Klaus Abbelen announced his retirement from driving ahead of the NLS8 round of the 2025 Nürburgring Langstrecken-Serie, marking the end of his active career as a competitor while the team he co-founded continued to operate.
