Three new teams came into Formula One in 1997: Prost, who replaced Ligier; Stewart, who arrived with the backing of the Ford Motor Company and Lola. Bridgestone entered into F1 and supplied tyres to five teams: Arrows, Prost, Minardi, Stewart and Lola. Williams dismissed Damon Hill and employed Heinz-Harald Frentzen, motivating Hill for a revenge on the track.
