Funny you should mention Reynard, their stillborn F1 design of the early-1990s begat both a success (the Benetton B194, correct me if I'm wrong) and a failure (the Pacific PR01), the latter racked up only 7 starts out of a possible 32 (none in the last 10 races) and no finishes in 1994. Bertrand Gachot actually declared he was glad to never have to drive the PR01 again after the inevitable double-DNQ in Adelaide.
Only at the season-opener in Brazil did a Pacific qualify on merit in 1994, inevitably in Gachot's hands.
Gachot was guaranteed to qualify in Imola thanks to Rubens Barrichello's accident. Paul Belmondo respectfully didn't take the late Roland Ratzenberger's place on the grid.
Both drivers were guaranteed to qualify in Monaco after Williams only ran Damon Hill and Simtek ran only David Brabham and Sauber withdrew after Karl Wendlinger's accident.
Both drivers were guaranteed to qualify in Spain after Sauber ran only Heinz-Harald Frentzen and Andrea Montermini crashed his Simtek and broke his ankles.
Gachot was guaranteed to qualify in Canada after Simtek again only ran one car for Brabham. To show just how little actual racing Gachot and Belmondo got to do that year, Belmondo covered the most distance in a race either driver would manage all season at Monaco, lasting 53 laps before retiring due to being physically fatigued!
Truth be told, the car was originally designed for 1993 with Michael Bartels (and Gachot? Or possibly David Coulthard since he drove for Pacific in F3000 that year?) driving but a lack of finance meant their entry was delayed until 1994 so the car was already a year out of date before it had even raced (and possibly even older as the Reynard F1 car was intended for 1992).
Reynard was also involved in the construction of the unraced DAMS F1 car.
