Prix), drivers including Damon Hill, Ukyo Katayama, Mark Blundell and Mika Salo scored some acceptable results with Blundell achieving a surprise 3rd place at the 1994 Spanish Grand Prix and Hill with 2nd at the aforementioned 1997 Hungarian Grand Prix, this partly was considered to be due to Yamaha collaborating with the John Judd Engine Organization to create a better and reliable engine however there were questions raised as to whether the Yamaha Engines used from 1993 until 1997 were just Judd engines with the Yamaha branding on top of this. 1994 was considered to be Yamaha's most successful year in terms of points accrued, apart from the Podium achieved by Blundell in Spain the Yamaha engine in the Tyrrell Car achieved 4 Fifth Place finishes and 1 Sixth Place finish over the course of the season, However, due to the inconsistency of the engine over the years they were often unreliable and were usually regarded as not very powerful, the Yamaha powered engine never secured a Fastest Lap or Pole Position despite being on the grid for nearly a decade. After the conclusion of the 1997 Formula One Season, Yamaha decided to pull out of the sport, a possible reason for this was due to a disagreement with Arrows regarding the 1998 engine's identification, Yamaha wished to carry out work on the engine with their engineers while Arrows wished for their own engineers to work on the engine instead while still having it badged as a Yamaha engine.
