This is still far from clear. Let me repeat:
Frentzen, Schumacher and Wendlinger were called the Mercedes baby group C drivers. One of these three came under attack by a person with a knife. Another F1 driver who had the same Rookie season with our baby Benz driver saved his life.
For the record we jot down the rookie seasons of our candidates.
Schumacher 1991 (Jordan, Benetton)
Wendlinger 1991 (Leyton House Racing)
Frentzen 1994 (Sauber)
Rookies in 1991: Schumacher, Wendlinger, Hakkinen, Blundell, Comas, Zanardi, van de Poele, Chaves, Barbazza, Bartels, Hattori
Rookies in 1994: Frentzen, Coulthard, Verstappen, Panis, Beretta, Salo, Ratzenberger, Lagorce, Adams, Schiattarella, Noda, Inoue, Deletraz, Montermini
Now we get closer. The only Mercedes V10 drivers were Wendlinger and Frentzen. Schumacher never drove Mercedes V10s. But the engine was only called Mercedes in the 1994 season. Before it was called Illmor and Sauber. So we are now pretty sure the baby Benz driver was
Frentzen. As we are looking for another German speaker we look for Austrians or Swiss. That would be
Ratzenberger, who ran a Simtek with Ford V8 engine. One of his teammates was David Brabham son of Sir Jack Brabham, triple champ and F1 designer.

Ratzenberger der Lebensretter von Frentzen: Bei einem Zwischenfall in einer Disco rettete Ratzenberger vielleicht Frentzen einmal das Leben. Als jemand bei einer Auseinandersetzung mit Frentzen ein Messer zog ging der große, kräftige Roland Ratzenbegrer auf Frentzens Kontrahent zu, überwältigte ihn und nahm ihm das Messer ab. So kam Frentzen dank Roland Ratzenberger ungeschoren aus dieser nicht ungefährlichen und recht brenzlichen Situation heraus.
This is probably the source of the riddle. Ratzenberger may have saved Frentzen's life in a dance bar (disco) when someone pulled a knife and the taller and stronger Ratzenberger overpowered the opponent and took away his knife.

Frentzen recounted an incident in Japan, when Ratzenberger came to the aid of a girl in a Japanese disco, confronting her knife-wielding attacker in the process.
This would place the incident either around the Aida GP 1994 or more likely in his pre F1 Japanese racing years when he was friend with other gaijin racers Mika Salo, Jacques Villeneuve, Johnny Herbert, Eddie Irvine and HH. Frentzen.

Khadija Adam, an Yves Saint Laurent model for eight years, lost her fiance, Austrian driver Roland Ratzenberger, who died after a crash. They were to be married this summer.

A amizade era grande e um episódio famoso ocorreu num bar da capital japonesa. Um executivo árabe discutiu com sua noiva oriental até chegar à agressão. Frentzen resolveu intervir, no que o nervosinho sacou uma faca e partiu em direção ao alemão. Sua sorte é que Ratzenberger agiu rápido, dando uma gravata no sujeito e o desarmando. “Roland salvou minha vida”, admite Frentzen, que lembra de outro episódio não tão heróico. “Ele também era muito malandro. Uma vez abandonei em Sugo e ele me deu carona após a bandeirada. Só que foi a 150 km/h para os boxes enquanto eu fazia de tudo para me agarrar ao carro... e desceu do cockpit rindo!”
This I don't understand.
Khadija Adam may have been the girl in question. I have been unable to find out more about the incident.
My apologies for suspecting a wild goose chase. This incident was very obscure and without tons of hints you can spend a lifetime researching it. I would appreciate tasks that can be fully defined in the initial question.
