The next step was the German Formula 3 Championship in 1989, where Frentzen competed against many future stars including Michael Schumacher and Karl Wendlinger. At the time, there was a big push by Bernie Ecclestone to have a German driver in the Formula One World Championship, so the ONS (the German National Motorsports committee) decided to support both Frentzen and Schumacher. The ONS put up the reward of a Formula One test to the driver who first would take a victory in a Formula 3 race. This ultimately ended up being Schumacher, in a controversial race at Zeltweg, Austria in which Frentzen claimed Schumacher had forced him off the track. However, Schumacher did not get the Formula One test drive anyway; Karl Wendlinger won the German Formula 3 Championship and Frentzen became joint runner-up with Schumacher (the two finishing on identical points totals).
