Yamaha developed a number of naturally-aspirated racing engines during their time in Formula One; between 1989 and 1997. They initially supplied engines for Zakspeed, in 1991 for Brabham, in 1992 for Jordan, from 1993 to 1996 for Tyrrell, and in 1997 for Arrows. These never won a race (Damon Hill nearly did so at the 1997 Hungarian Grand Prix), but drivers including Damon Hill, Ukyo Katayama, Mark Blundell and Mika Salo scored some acceptable results with them. However, their engines were often unreliable and were usually regarded as not very powerful. [1] [3]
