He and his wife Jennifer ventured to Great Britain (with a self-imposed 2-year limit of making it big) to allow him to participate in the British Formula Atlantic Championship, which he won, leading to a test with BRM.

Holbert drove the final lap of the race with an overheating (and steaming) engine caused by an airflow blockage to the radiator that cooled the heads, it seized as he crossed the finish line.

He finished sixth at the 1984 24 Hours of Le Mans driving with Jarier and fellow Australian, 1980 World Champion Alan Jones making his Le Mans début (and indeed his only start), in a Kremer Racing Porsche 956B after the factory backed Rothmans team boycotted the event over the Automobile Club de l'Ouest's new fuel restriction rules.

Schuppan and Jones fought for the lead in the first few hours of the race with the Lancia LC2 of Bob Wollek and Alessandro Nannini, until the nose of the 956 was damaged by a spinning Roger Dorchy at Mulsanne Corner, losing the team a few laps in repairs.

The Kenwood sponsored 956 fought back to be again fighting for the lead, and near the end of the race Jarier was 2 laps down but catching the leading Joest Racing Porsche driven by Klaus Ludwig and Henri Pescarolo (the eventual winners) by over 10 seconds per lap.

In his home country Australia, Schuppan won the 1976 Rothmans International Series run for Formula 5000 cars, driving a Lola T332-Chevrolet.

He drove for the Holden Dealer Team in 1981, partnering John Harvey in a Holden VC Commodore to 4th place in the Hang Ten 400 after starting the race, but never got to drive the car at Bathurst after a broken front wheel sent Harvey into the guardrail and retirement on lap 37.

Allan Moffat and Schuppan started on pole and were leading the 1976 Hardie-Ferodo 1000 when their XB Falcon GT Hardtop retired with engine failure in lap 87.

In May 2006, Schuppan was elected into the Club International des Anciens Pilotes de Grand Prix F1, an eminent organisation based in Monaco.

[5] Schuppan also played an important role in bringing Formula One to the city of Adelaide in his home state of South Australia.

F1 boss Bernie Ecclestone had originally favoured the Australian Grand Prix to be held in Sydney.

However, the Premier of South Australia, John Bannon, asked Schuppan (who knew Ecclestone personally) to come and take a look at Adelaide.
