In 1959, she won the European Women’s Cup in a Volvo ahead of Pat Moss, the sister of Stirling. She was presented the trophy at the Monte Carlo Rally ceremony by Princess Grace of Monaco in 1960 – a trophy she won again the following year.
She also received the Women’s Cup in international rallying (Coupe des Dames) in 1959 and 1961. In 1960, she became a works driver for Volvo.
Life As a Mercedes Works Driver
Mercedes-Benz brought the successful rally driver into the works team together with her co-driver Ursula Wirth in 1962.
In a Mercedes-Benz 220 SE (W111), the women’s team won the Women’s Cup at the four-day Swedish Rally to the Midnight Sun in ’62, followed by a sixth-place finish place at the 22nd Raid Polski and 12th place at the Liège-Sofia-Liège Rally in the same year.
On 4 November 1962, together with co-driver Wirth, Ewy phenomenally won the VI Argentinian Touring Car Grand Prix. The women’s team won in all six stages of the 4,626km race and set a new record – increasing the average speed of the winning team of the previous year from 121.234 km/h to 126.872 km/h.
In the following years, Ewy was successful again and again at renowned rallies and long-distance races, including the 1963 win of the Women’s Cup at the Monte Carlo Rally, the win in the up to 2,500cc displacement class at a six-hour race at the Nürburgring, as well as third place at the Argentinian Touring Car Grand Prix.
In 1964, together with Eva Maria Falk, she was able to win in the up to 2,500cc displacement class at the Monte Carlo Rally, finish fifth at the International Acropolis Rally and secure third place at the Spa–Sofia–Liège Rally.
Ewy ended her racing career at the 1964 Argentinian Touring Car Grand Prix, where she finished third. In June of the same year, she married the then Director of Motorsport Activities at Mercedes-Benz, Baron Alexander von Korff, in the chapel of the old castle in Stuttgart.
She would later move back to Sweden after the death of her husband in 1977 but remained – and will always remain – closely associated with the brand and as an ambassador for Mercedes-Benz Classic.
