The 1994 Simtek season was Simtek's 1st season as a constructor. Their season was overshadowed by the death of their driver Roland Ratzenberger in qualifying for the San Marino Grand Prix. Among their race drivers was David Brabham, the son of Sir Jack Brabham, who had previously drove for his father's team Brabham and competed in all races this year.
This began Simtek's Formula One campaign. Brabham qualified in 26th place, and Ratzenberger failed to qualify. Brabham finished the race in 12th place.
In this race, Ratzenberger finished in 11th and last place, whilst Brabham was out of the Grand Prix by lap 2 after electrical problems.
At this race, things took a tragic turn, as during qualifying on April 30, Roland Ratzenberger crashed at the Curva de Villeneuve at high speed suffering a basal skull fracture. He died in the hospital. David Brabham opted to continue racing out of respect for his team-mate. During the race the next day, Williams driver and race leader Ayrton Senna also died after crashing at the Tamburello corner.
After the loss of Ratzenberger, Simtek ran just one car for the next race in Monaco. Brabham lasted 45 laps before retiring with engine failure.
The team promoted their test driver Andrea Montermini to a race seat, replacing the late Ratzenberger, from this race onward. Sadly, Montermini's season ended before it began after a huge accident in qualifying, breaking his ankles. Brabham qualified in 24th and finished in 10th, running 4 laps down.
After the injuries sustained by Montermini which kept him out of the season, Simtek again ran just the one car of Brabham. The Australian finished the race in 14th.
Jean-Marc Gounon became Brabham's third-team mate this year, replacing Montermini. He finished his debut race in 9th, whilst Brabham retired again.
