Brabham (1992)

Hill started his Grand Prix career during the 1991 season as a test driver with the championship-winning Williams team while still competing in the F3000 series.^[26] However, midway through 1992 Hill broke into Grand Prix racing as a driver with the dying Brabham team. The formerly competitive team was in serious financial difficulties. Hill started the season only after three races, replacing Giovanna Amati after her sponsorship had failed to materialise.^[27] Amati had been unable to get the car through qualifying but Hill matched his teammate, Eric van de Poele, by qualifying for two races, the mid-season British and Hungarian Grands Prix. Hill continued to test for the Williams team that year and the British Grand Prix saw Nigel Mansell win the race for Williams, while he finished last in the Brabham.^[28] The Brabham team collapsed after the Hungarian Grand Prix and did not complete the season.^[29]

Williams (1993–96)

When Mansell's teammate Riccardo Patrese left Williams to drive for Benetton in 1993, Hill was unexpectedly promoted to the race team alongside triple World Champion Alain Prost ahead of more experienced candidates such as Martin Brundle and Mika Häkkinen.^[30] Traditionally, the reigning driver's World Champion carried the number "1" on his car and his teammate took the number "2". Because Mansell, the 1992 champion, was not racing in Formula One in 1993, Williams as Constructors' Champion were given numbers "0" and "2". As the junior partner to Prost, Hill took "0", the second man in Formula One history to do so, after Jody Scheckter in 1973.^[31]

1993

The season did not start well when Hill spun out of second place shortly after the start of the South African Grand Prix and failed to finish the race after colliding with Alessandro Zanardi on lap 17.^[32] At the Brazilian Grand Prix, Hill qualified and spent the early stages of the race running second behind Prost, and then took the lead when Prost crashed, but was relegated back to second by another three-time World Champion, Ayrton Senna. Nevertheless, the race still gave Hill his first podium finish.^[33]

In the next round in Europe, Hill again finished second behind Senna and ahead of a lapped Prost. In his first full season, Hill benefited from the experience of his veteran French teammate.^[34] He continued to impress as the season went on, and in San Marino Hill took the lead at the start, though he was passed by Prost and Senna and ultimately retired with a spin due to a brake failure.^[35] Mechanical problems returned in Spain where he kept pace with Prost for most of the race only for his engine to fail.^[36]

After strong podiums in Monaco and Canada, Hill took his first career pole in France, finishing second to Prost after team orders prevented him from seriously challenging for the win.^[37] He looked set to win the British Grand Prix before another engine failure put him out and led the German Grand Prix comfortably only to suffer a puncture with two laps left, handing the win to Prost.^[38]

At the Hungarian race, Hill did take his first career win after leading from start to finish. In doing so he became the first son of a Formula One Grand Prix winner to take victory himself,^[15] and he followed it with two more wins, first at Spa where he took the lead following a pit stop problem for Prost,^[39] and then at the Italian Grand Prix where Prost's engine failed towards the end. His third consecutive win clinched the Constructors' Championship for Williams and moved him temporarily to second in the Drivers' standings.^[40] At the Portuguese Grand Prix Hill came from the back of the grid to third, having stalled on the warm up lap from pole.^[41] He finished the season by finishing fourth in Japan and third in Australia, though he lost second in the Drivers' Championship to Ayrton Senna, who passed Hill by winning the last two races.^[42]

1994

In 1994, Ayrton Senna joined Hill at Williams. As the reigning champion, this time Prost, was again no longer racing, Hill retained his number '0'. The pre-season betting was that Senna would coast to the title,^[43] but the Benetton team and Michael Schumacher initially proved more competitive and won the first three races. At the San Marino Grand Prix on 1 May, Senna died after his car crashed into a concrete barrier while he was leading. With the team undergoing investigation from the Italian authorities on manslaughter charges, Hill found himself team leader with only one season's experience in the top flight. It was widely reported at the time that the Williams car's steering column had failed, though Hill told BBC Sport in 2004 that he believed Senna simply took the corner too fast for the conditions, referring to the fact that the car had just restarted the race with cold tyres after being slowed down by a safety car.^[44]

Hill represented Williams alone at the next race, the Monaco Grand Prix. His race ended early in a collision involving several cars on the opening lap of the race. For the following race, the Spanish Grand Prix, Williams's test driver David Coulthard was promoted to the race team alongside Hill, who won the race just four weeks after Senna's death.^[45]

Schumacher led by 66 points to 29 by the midpoint of the season. At the French Grand Prix, Frank Williams brought back Nigel Mansell, for the French, European, Japanese and Australian Grands Prix with Coulthard doing the majority of the 1994 season. Mansell earned approximately £900,000 for each of his four races, while Hill was paid £300,000 for the entire season, though Hill's position as lead driver remained unquestioned.^[46] Hill came back into contention for the title after winning the British Grand Prix, a race his father had never won.^[47] Schumacher was disqualified from that race and banned for two further races for overtaking Hill during the formation lap and ignoring the subsequent black flag.^[48] Four more victories for Hill, three of which were in races where Schumacher was excluded or disqualified, took the title battle to the final event at Adelaide. At Schumacher's first race since his ban, the European Grand Prix, he suggested that Hill (who was eight years his senior) was not a world-class driver. However, during the penultimate race at the Japanese Grand Prix, Hill took victory ahead of Schumacher in a rain-soaked event. This put Hill just one point behind the German before the last race of the season.^[49]

Neither Hill nor Schumacher finished the season-closing Australian Grand Prix, after a controversial collision which gave the title to Schumacher. Schumacher ran off the track hitting the wall with the right-hand side of his Benetton while leading.^[50] Coming into the sixth corner Hill moved to pass the Benetton and the two collided, breaking the Williams's front left suspension wishbone, and forcing both drivers' retirement from the race.^[51] BBC Formula One commentator Murray Walker, had often maintained that Schumacher did not cause the crash intentionally,^[52] but Williams co-owner Patrick Head felt differently. In 2006 he said that at the time of the incident "Williams were already 100% certain that Michael was guilty of foul play" but did not protest Schumacher's title because the team was still dealing with the death of Ayrton Senna.^[53] In 2007, Hill explicitly accused Schumacher of causing the collision deliberately.^[54]

Hill's season earned him the 1994 BBC Sports Personality of the Year.^[55]

1995

Coming into the 1995 season, Hill was one of the title favourites.^[56] The Williams team were reigning Constructors' Champions, having beaten Benetton in 1994, and with young David Coulthard, who was embarking on his first full season in Formula One, as teammate, Hill was the clear number one driver. The year seemed to start well with pole position in Brazil, although a spin while in the lead due to a mechanical problem handed the lead to Schumacher.^[57] But wins in the next two races put him in the championship lead. However, Schumacher won seven of the next twelve races, and took his second title with two races to spare, while Benetton took the Constructors' Championship. Schumacher and Hill had several on-track incidents during the season, two of which led to suspended one-race bans for both. Schumacher's penalty was for blocking and forcing Hill off the road at the Belgian Grand Prix;^[58] Hill's was for colliding with Schumacher under braking at the Italian Grand Prix.^[59] Hill's season finished positively when he won the Australian Grand Prix by finishing two laps ahead of the runner-up, Olivier Panis in a Ligier.^[56]

1996

In 1996 the Williams car was clearly the quickest in Formula One and Hill went on to win the title ahead of his teammate, reigning Indycar champion Jacques Villeneuve, becoming the first son of a Formula One champion to win the championship himself.^[60] Taking eight wins and never qualifying off the front row, Hill enjoyed by far his most successful season. At Monaco, where his father had won five times in the 1960s, he led until his engine failed, curtailing his race and allowing Olivier Panis to take his only Formula One win.^[61] Near the end of the season, Villeneuve began to mount a title challenge and took pole in the Japanese Grand Prix, the final race of the year. However, Hill took the lead at the start and won both the race and the championship while the Canadian retired.^[62] Hill equalled the record for starting all 16 races of the season from the front row, matching Ayrton Senna in 1989 and Alain Prost in 1993.^[63]

Despite winning the title, Hill learned before the season's close that he was to be dropped by Williams in favour of Heinz-Harald Frentzen for the following season.^[60] Hill left Williams as the team's second most successful driver in terms of race victories, with 21, second only to Mansell.^[64] Hill's 1996 World Championship earned him his second BBC Sports Personality of the Year Award, making him one of only five people to receive the award twice – the others being boxer Henry Cooper, Nigel Mansell, Andy Murray and Lewis Hamilton. Hill was also awarded the Segrave Trophy by the Royal Automobile Club. The trophy is awarded to the British national who accomplishes the most outstanding demonstration of the possibilities of transport by land, sea, air, or water.^[65]

Arrows (1997)

Hill became the fourth driver in nine years to win the World Drivers' Championship for Williams and not drive for the team the following season, as occurred with Nelson Piquet (1987 champion – 1988 driver for Lotus), Nigel Mansell (1992 champion – 1993 driver in the US-based Indy Car World Series instead of F1) and Alain Prost (1993 champion – retired in 1994). As World Champion, Hill was in high demand and had offers for a race seat from McLaren, Benetton and Ferrari but not adequately financially valued despite his status.^[54] As a consequence, he opted to sign for Arrows, a team which had never won a race in its 20-year history and had scored only a single point the previous year. Hill's title defence in 1997 proved unsuccessful, getting off to a poor start when he only narrowly qualified for the Australian Grand Prix and then retired on the parade lap. The Arrows car, which used tyres from series debutant Bridgestone and previously unproven Yamaha engines, was generally uncompetitive, and Hill did not score his first point for the team until the British Grand Prix at Silverstone in July. His best result for the year then came at the Hungarian Grand Prix. On a day when the Bridgestone tyres had a competitive edge over their Goodyear rivals, Hill qualified third in a car that had not previously placed higher than 9th on the grid. During the race, he passed his rival and new championship contender, Michael Schumacher, on the track and was leading late in the race, 35 seconds ahead of the eventual 1997 World Champion, Villeneuve, until a hydraulic problem drastically slowed the Arrows. Villeneuve thus passed Hill, who finished second.^[66]

Jordan (1998–99)

Only after one year with Arrows, Hill came close to signing a deal with Alain Prost's team, before deciding to instead sign up with the Jordan team for the 1998 season.^[67] His new teammate was Ralf Schumacher, younger brother of Michael. In the first half of the season, the Jordan 198 car was off the pace and unreliable^[68] until improvements in performance from the Canadian Grand Prix. During that race, Hill progressed to second place as others retired or made pit stops for fuel. On lap 38, Michael Schumacher, who was delayed by a stop-and-go penalty after forcing Frentzen's Williams off the track, caught Hill on the home straight; Hill moved across the track three times to block Schumacher, who took the place by running over the kerbs at the last chicane. Hill then ran fourth after his only pit stop before retiring due to an electrical failure. After the race, Schumacher accused Hill of dangerous driving. Hill responded by stating that Schumacher "cannot claim anyone drives badly when you look at the things he's been up to in his career. He took Frentzen out completely."^[67] At the German Grand Prix, Hill scored his first point of the year and at the Belgian Grand Prix, in very wet conditions, he took the Jordan team's maiden win. At that race, Hill was leading late in the race, with teammate Schumacher closing rapidly, when he asked the team whether they would be allowed to race each other. Team principal Eddie Jordan ordered Ralf Schumacher to hold position instead of risking losing a 1–2 finish.^[69] The victory was his first since being dropped by the Williams team. Hill finished the season with a last lap pass on Frentzen at the Japanese Grand Prix, which earned him fourth place in the race and Jordan fourth position in that year's Constructors' Championship.^[70]

Hopes were high for 1999, but Hill did not enjoy a good season. Struggling with the newly introduced four-grooved tyres, he was outpaced by his new teammate, Heinz-Harald Frentzen, who was Hill's replacement at Williams two years prior.^[71] After a crash at the Canadian Grand Prix, Hill announced plans to retire from the sport at the end of the year, but after failing to finish the French Grand Prix that Frentzen won, he considered quitting the sport immediately.^[72]

Jordan persuaded Hill to at least stay for the British Grand Prix. Going into that race weekend, Hill announced he would retire after the Grand Prix, leading Jordan to test Jos Verstappen in case Hill had to be quickly replaced.^[73] Following a strong fifth place at his home event, however, Hill changed his mind and decided to see out the year.^[74] His best result for the remainder of the season was sixth place, which he achieved in both Hungary and Belgium. With three races of 1999 to go, there were rumours that the Prost Grand Prix team would release Jarno Trulli early after he signed for Jordan's 2000 campaign as Hill's replacement.^[75] At the same time, his teammate, Frentzen, became a title contender going into the final few races of the season and, eventually, finished third in the championship. In so doing, both Hill and Frentzen helped Jordan to achieve its best-ever finish with a third position in the Constructors' Championship. Hill's last race was the Japanese Grand Prix where he spun off the track and pulled into the pit lane citing mental fatigue.^[76]
