Toleman (1984) Rookie testing Ahead of the 1984 season, Senna was linked to many Formula One teams but received very few offers he liked. He had previously declined a long-term contract from
McLaren, and that door was formally closed when
Alain Prost (unexpectedly fired by Renault after finishing runner-up in 1983) received the second McLaren seat. He was also linked to
Lotus and
Brabham, but both teams' title sponsors (
Imperial Tobacco /
John Player & Sons for Lotus and
Parmalat for Brabham) wanted drivers from their respective home countries, so Lotus retained Nigel Mansell and Brabham signed brothers
Teo and
Corrado Fabi. Consequently, Senna joined
Toleman, a relatively new team, using less competitive
Pirelli tyres. He was paired with Venezuelan
Johnny Cecotto, a former
Grand Prix motorcycle racing world champion. In 1983, Senna tested for McLaren, Brabham,
Williams, and
Toleman, although Williams also lacked a vacancy. Both Williams boss
Frank Williams and McLaren boss Ron Dennis observed that Senna insisted on running their cars before anyone else, (other than their regular drivers such as
Keke Rosberg) so that he would have the best chance of a good showing by having a fresh car. During his test for Williams at
Donington Park, Senna completed 40 laps and was quicker than the other drivers, including Rosberg, Williams's reigning World Champion. A combination of tyre issues and a fuel-pressure problem resulted in his failure to qualify for the
San Marino Grand Prix, the only time this happened during his career. Toleman decided not to run both cars during Friday qualifying at
Imola due to a dispute with tyre supplier
Pirelli (Toleman were in the process of switching from Pirelli to
Michelin). Senna then suffered a fuel-pressure problem in the wet Saturday session at Tosa (the furthest point on the circuit from the pits) and did not have enough time for it to be fixed to allow him to make the grid. Senna's best result of the season came at the
Monaco Grand Prix, the first wet-weather race of the season. Qualifying 13th on the grid, he made steady progress in climbing through the field, passing
Niki Lauda for second on lap 19. He quickly began to cut the gap to race leader
Alain Prost. Before he could attack Prost, the race was stopped on lap 31 for safety reasons, as the rain had grown even heavier. At the time the race was stopped, Senna was catching Prost by about 4 seconds per lap (while the
Tyrrell-
Ford of
Stefan Bellof was catching both at the same rate, although he was later disqualified due to weight restrictions broken by Tyrrell). Early on his career, Senna developed a reputation for providing very specific technical details about the performance of his cars and track conditions long before the advent of telemetry. This skill led Toleman's
Pat Symonds, Senna's first Formula One race engineer, to regard the
Dallas Grand Prix as the initial highlight of Senna's debut season, instead of Monaco. In an interview, Symonds recalled:The car was reasonably competitive there, so we expected to have a good race, but Ayrton spun early in the race. He then found his way back through the field in a quite effective way and we were looking for a pretty good finish, but then he hit the wall, damaged the rear wheel and the driveshaft and retired, which was a real shame. The real significance of that was that when he came back to the pits he told me what happened and said "I'm sure that the wall moved!" And even though I've heard every excuse every driver has ever made, I certainly hadn't heard of that one! But Ayrton being Ayrton, with his incredible belief in himself, the absolute conviction, he then talked me into going with him after the race to have a look at the place where he had crashed. And he was absolutely right, which was the amazing thing! Dallas being a street circuit, the track was surrounded by concrete blocks and what had happened – we could see it from the tyre marks – was that someone had hit at the far end of the concrete block and that made it swivel slightly, so that the leading edge of the block was standing out by a few millimetres. And he was driving with such precision that those few millimetres were the difference between hitting the wall and not hitting the wall. While I had been, at first, annoyed that we had retired from the race through a driver error, when I saw what had happened, when I saw how he had been driving, that increased my respect for the guy by quite a lot.That season, Senna took two more podium finishes—third at the
British and
Portuguese Grands Prix—and placed ninth in the Drivers' Championship with 13 points overall. He did not take part in the
Italian Grand Prix after he was suspended by Toleman for being in breach of his contract by entering talks with
Lotus for 1985 without informing the Toleman team first. Although Senna did have a £100,000 buyout clause in his contract, the team had to be informed before discussions with another team started. Senna became the first driver Lotus had signed that was not personally chosen by team founder
Colin Chapman, who had died in 1982. Senna had some health issues during the season. Concerned about his low weight, he hired Nuno Cobra to assess his physical condition. an opinion shared by race engineer
Steve Hallam, who recognised Senna's "truly special" talent. Senna led at the San Marino, Monaco, British and German Grands Prix but retired from all these races either from engine failures or running out of fuel, and he had a huge accident at the French Grand Prix at the Circuit Paul Ricard's fastest corner after breaking the engine in the middle of the corner. He did not finish in the points again until coming second at the
Austrian Grand Prix, despite taking pole three more times in the intervening period. His determination to take pole at the
Monaco Grand Prix had infuriated Alboreto and Niki Lauda; Senna had set a fast time early and was accused of deliberately baulking the other drivers by running more laps than necessary, a charge he rejected, although the accusations continued in
Canada when drivers accused him of running on the racing line when on his slow down lap forcing others on qualifiers to move off line and lose time. Two more podiums followed in
the Netherlands and
Italy, before Senna added his second victory in wet-dry conditions, at the
Circuit de Spa-Francorchamps in Belgium. Senna's relationship with de Angelis soured over the season, as both drivers demanded top driver status within Lotus and, after spending six years at the team, De Angelis departed for Brabham at the end of the year, convinced that Lotus were becoming focused on the Brazilian driver. Senna and de Angelis finished the season fourth and fifth respectively in the driver rankings, separated by five points. In terms of qualifying, Senna had begun to establish himself as the quickest in the field; his tally of seven poles that season was far more than that of any of the other drivers. Renault's
V6 qualifying engines were reported to be producing over .
1986: Eight pole positions and eight podiums at the
1986 British Grand Prix De Angelis was replaced at Lotus by
Scotland's
Johnny Dumfries after Senna vetoed Derek Warwick from joining the team, saying that Lotus could not run competitive cars for two top drivers at the same time. Senna allegedly pushed for his former flatmate and fellow Brazilian
Maurício Gugelmin to join the team as a pure number two driver, but the team's major sponsor
John Player & Sons (JPS) insisted on a British driver, which led to the signing of Dumfries. Senna later admitted "It was bad, bad. Until then I had a good relationship with Derek." Senna started the season well, coming second in
Brazil behind the
Williams-
Honda of fellow countryman
Nelson Piquet, and winning the
Spanish Grand Prix by just 0.014s from Piquet's teammate Nigel Mansell, in one of the closest finishes in Formula One history, to find himself leading the World Championship after two races. The 98T resembled the 97T that came before it, a quick car with superiority on tight, bumpy circuits but plagued with poor reliability, particularly in the second half of the season, as it saw him drift behind the Williams pairing of Mansell and Piquet, as well as the defending and eventual champion Alain Prost. Nonetheless, Senna was once more the top qualifier with eight poles, with a further six podium finishes, including another win at the
Detroit Grand Prix, thus finishing the season fourth in the driver's standings again, with a total of 55 points. The 1986 Formula One cars were the most powerful cars in history, with Senna's 98T producing over in qualifying and in the race. After winning the
Detroit Grand Prix from Frenchmen Prost and
Jacques Laffite that took place one day after
Brazil was eliminated from the
1986 FIFA World Cup by
FranceSenna asked a trackside supporter for the
Brazilian flag and he drove one lap waving it. Thereafter, he repeated this ritual every time he won a race.
1987: Last season at Lotus raced by Senna in
Team Lotus had a new engine deal in 1987, running the same turbocharged Honda V6 engines as Williams had used to win the previous year's Constructors' Championship, and with them came a new teammate, 34-year-old Japanese driver
Satoru Nakajima, who was a test driver employed directly by Honda. The team guaranteed Senna contractually preferential treatment over Nakajima in the allocation of equipment. Senna started the season with mixed fortunes: a podium at the
San Marino Grand Prix was tempered by controversy at the following
race at Spa-Francorchamps, where he collided with Mansell; afterward in the pits an irate Mansell grabbed Senna by the throat and had to be restrained by Lotus mechanics. Senna then won two races in a row, which helped him take the lead in the World Championship: the ensuing
Monaco Grand Prix (the first of his record six victories at the
Principality) and the
Detroit Grand Prix, his second victory in two years at the angular
Michigan street circuit, and the first ever for an
active suspension Formula One car. As the championship progressed, it became evident that the Williams cars had the advantage over the rest of the field, the gap between the Honda-engined teams made most obvious at the
British Grand Prix, where Mansell and Piquet, in the superior Williams cars, lapped the Lotuses of Senna and Nakajima who finished 3rd and 4th respectively. Senna became dissatisfied with his chances at Lotus and at
Monza it was announced that he would be joining McLaren for 1988. Senna was fined $15,000 for punching a corner marshal after they refused to push his stalled car in Mexico; he then finished the season strongly, coming second in the final two races in
Japan and
Australia; post-race scrutiny at the final race found the brake ducts of his Lotus to be wider than permitted by the rules and he was disqualified, bringing his last and most successful season with Lotus to a sour end. Senna was classified third in the final standings, with 57 points, six podium finishes and only one pole position. This season marked a turning point in Senna's career as, throughout the year, he built a deep relationship with Honda, which paid big dividends, as McLaren had secured Williams's supply of Honda's V6 turbo engines for 1988.
McLaren (1988–1993) 1988: First world championship . In 1988, due to the relationship he had built up with Honda throughout the 1987 season with Lotus, and with the approval of McLaren's number-one driver and then-double world champion, Alain Prost, Senna joined the McLaren team. The foundation for a fierce competition between Senna and Prost was laid, culminating in a number of dramatic race incidents between the two over the next five years. The experienced pair also quickly realized that despite their personal rivalry, they had to work together, especially in testing, to keep ahead of their main opposition from
Ferrari, Williams,
Benetton, and Lotus. One notable incident of the year was at the
Monaco Grand Prix, where Senna out-qualified Prost by 1.4 seconds and led for most of the race before crashing on lap 67. Instead of returning to the pit lane, Senna was so distressed by his mistake that he went back to his apartment and did not contact the team until he walked into the pit garage as they were packing up later that night. After team manager
Jo Ramirez called him through his Monaco apartment's cleaner, hours after he had crashed, Senna was still devastated by his own mistake. As the television cameras had not captured his crash, team boss
Ron Dennis did not know what had caused his
DNF until then, although Prost speculated that judging from the tyre marks, it appeared as though Senna had clipped the inside barrier at Portier, which pitched him into the outside guard rail. At the
Portuguese Grand Prix, Prost made a slightly faster start than Senna who, as he would a number of times, dived into the fast first corner ahead. Prost responded and went to pass Senna at the end of the first lap. Senna swerved to block Prost, forcing the Frenchman to nearly run into the pit wall at . Prost kept his foot down and soon edged Senna into the first corner and started pulling away. Prost, normally a calm individual, was angered by Senna's manoeuvre, and the Brazilian got away with a warning from the FIA. At the post-race team debrief, Prost voiced his anger at the move, which prompted Senna to apologize to Prost for the incident. Ultimately, the pair won 15 of 16 races in the dominant
McLaren MP4/4 in 1988 with Senna coming out on top, winning his first Formula One world championship title by taking eight wins to Prost's seven. During the season, Senna rewrote the record books. His eight wins beat the old record of seven jointly held by
Jim Clark () and Prost (1984). His 13 pole positions also beat the record of nine held by Nelson Piquet (1984). . The biggest incident of the year happened at the
Italian Grand Prix at
Monza. With two laps remaining, Senna held a five-second lead over the
Ferraris of
Gerhard Berger and
Michele Alboreto, who were closing in on the
McLaren MP4/4 (Prost had earlier retired with a badly misfiring engine). Going into the Rettifilo chicane, Senna closed on the
Williams FW12 of
Jean-Louis Schlesser (standing in for the unwell Nigel Mansell). Schlesser steered wide, attempting to give Senna room to lap him, losing then regaining control to avoid going into the sand trap, and the two collided; Senna's car was beached on top of a curb and had stalled.
Ferrari went on to finish 1–2, the first in an
Italian Grand Prix since the death of the team's founder
Enzo Ferrari. This proved to be the only race McLaren did not win in 1988.
1989: Runner-up to Alain Prost In , the rivalry between Senna and Prost intensified into numerous battles on the track and a psychological war off it. Some controversy also arose after the French GP press conference when Ron Dennis declared that they found consistent differences between the Honda engines from Prost and Senna, to the detriment of Prost. Tension and mistrust between the two drivers increased when Senna overtook Prost at the restart of the
San Marino Grand Prix, a move that Prost claimed violated a pre-race agreement (Senna denied the existence of any agreement, although Prost's story was backed up by
John Hogan of the team's major sponsor,
Marlboro). A discussion between the two drivers and Dennis during a test session at the Pembrey circuit in Wales served to effectively confirm Senna and Prost's personal animosity to Dennis and the team. Senna took an early lead in the championship with victories in San Marino,
Monaco, and
Mexico. Senna led every lap of those races, a feat unequalled until
Sebastian Vettel replicated it in . Senna also managed to win in
Germany,
Belgium, and
Spain, but the mechanical failures occurred in
Phoenix,
Canada,
France,
Britain, and
Italy, together with collisions in
Brazil and
Portugal, swung the title in Prost's favour. in Prost took the 1989 world title after a collision with Senna at the
Suzuka Circuit in
Japan, the penultimate race of the season, which Senna needed to win to remain in contention for the title. Prost had managed to leave the grid faster than Senna by removing the
gurney flap from his car, which was unbeknownst to Senna. A large fine and temporary suspension of his
FIA Super License followed in the winter of 1989, and an irate Senna engaged in public criticism of the
FIA and its then-president,
Jean-Marie Balestre, whom he blamed for his disqualification in Japan. Senna claimed that Balestre had forced the race stewards to disqualify him so his fellow Frenchman Prost could win the championship, though the stewards of the meeting denied that Balestre forced their decision, claiming that he was not present when the decision was made. Senna finished the season second with six wins and one second place.
1990: Second world championship raced by Senna in . With it, he won his second world championship. In 1990, Prost left McLaren for
Ferrari, burning bridges on his way out. He was replaced by the Austrian
Gerhard Berger, who became Senna's close friend. Senna took a commanding lead in the championship with six wins, two second-places, and three thirds. Among his victories were the opening round on the wide streets of
Phoenix, in which he diced for the lead for several laps with
Jean Alesi's
Tyrrell before coming out on top, and in
Germany, where he fought Benetton driver Alessandro Nannini throughout the race for the win. However, Prost mounted a fierce challenge and scored five wins that season, including a crucial victory in
Spain where he and teammate
Nigel Mansell finished 1–2 for the Scuderia. Senna had gone out with a damaged radiator, and the gap between Senna and Prost was now reduced to nine points with two races left. At the penultimate round of the championship in
Japan, where Senna and Prost collided the previous year, Senna took pole ahead of Prost. Before qualifying, Senna had sought assurances from the organisers to move pole position left onto the clean side of the racetrack, where the racing line was. He later claimed that this agreement was not honored, possibly due to Balestre's interference. In addition, as revealed by journalist Maurice Hamilton, the FIA had warned that crossing the yellow line of the pit exit on the right to better position oneself at the first corner would not have been appropriate, further infuriating Senna. Prost believed that Senna's actions were intentional, as (based on Honda telemetry) Senna continued speeding up as the two went into the corner. He added that he considered retiring from the sport after the incident. However, Senna initially denied that he intentionally wrecked Prost. When pundit and former champion
Jackie Stewart confronted him about his actions and brought up his history of on-track accidents and collisions, Senna feigned outrage, replying that "if you no longer go for a gap that exists, you are no longer a racing driver." One year later, Senna admitted that he intentionally wrecked Prost as payback for 1989, as well as his anger over the FIA's decision to disqualify him in 1989 and its pole position ruling in 1990. He later apologized to Stewart for his remarks in 1989, telling him that "God won't allow me to live this lie." Prost's Ferrari suffered a downturn in performance and was not competitive, but Nigel Mansell, now with Williams, was driving the
Adrian Newey designed Williams-Renault. Senna won the first four races in Phoenix, Brazil, Imola, and Monaco as his rivals struggled to match his pace and reliability. Mansell scored only six points by the time Senna had 40 points. At the
Spanish Grand Prix, Senna and Mansell went wheel-to-wheel with only centimetres to spare, at over 320 km/h (200 mph) down the main straight, a race which the Briton eventually won. Senna also got into several accidents and mishaps, including a jet-skiing accident before the
Mexican Grand Prix; a crash in qualifying at that race at the fastest corner on the track; a retirement on the final lap of the
British Grand Prix (Mansell eventually gave Senna a ride back to the pits during his victory lap); a testing accident at
Hockenheim that sent Senna's car 15 feet into the air and forced him to spend the night in the hospital; and a retirement at the
German Grand Prix after running out of fuel. To save the season, Senna demanded additional engine upgrades from Honda. These modifications, including modifications introduced at Hungary and variable inlet trumpets introduced at Belgium enabled him to make a late-season push. He won three more races to pull away from Mansell. Once again, Senna clinched the title in
Japan when Mansell (who needed to win) went off at the first corner while running third and beached his Williams in the gravel trap. Senna finished second, handing the victory to teammate Berger at the last corner as a thank-you gesture for his support over the season. At the end of the season, Senna won his third consecutive
Autosport International Racing Driver Award. At that year's FISA gala dinner, he gave Balestre a helmet because of the sincere atmosphere and as an insulting psychological gesture.
1992: Unsuccessful challenge to the Williams FW14B in his
McLaren MP4/7A. Senna considered moving to Williams for the 1992 season, but Honda's CEO,
Nobuhiko Kawamoto, personally requested that he remain at McLaren-Honda, which Senna did out of a sense of loyalty. In addition to Alain Prost's recommendation, Honda had played an important part in bringing Senna with them to McLaren. In 1992, Williams's all-conquering
FW14B car dominated the season. It boasted aerodynamic-enhancing active suspension and a powerful Renault V10 engine, which was now more powerful than Honda's. By contrast, the
McLaren MP4/7A was beset by production delays and did not debut until round three. The team struggled to catch up to Williams' technological advantage, building a semi-automatic gearbox for the first time and trialing an active suspension system. The new car suffered from reliability issues and was unpredictable in fast corners. Honda left Formula One at the end of the season. Senna won three races (
Monaco,
Hungary, and
Italy) and finished fourth overall in the championship, behind the Williams duo of Mansell and
Riccardo Patrese, and Benetton's
Michael Schumacher. During this time, relations between Senna and Schumacher grew testy. At the
Brazilian Grand Prix, Schumacher accused Senna of "playing around" while attempting to overtake Senna, who had a problem with his engine, a fact that Schumacher was apparently unaware of at the time. At the
French Grand Prix, Schumacher collided with Senna, resulting in Senna's retirement. Senna later confronted Schumacher, who admitted responsibility for the accident. At a test session for the
German Grand Prix, Senna and Schumacher had a confrontation in the pits, with Senna grabbing Schumacher by the collar and accusing him of endangering him by blocking him on the track. Senna grew increasingly worried about driver safety during the season. At round two in
Mexico, he suffered a major crash during practice and temporarily wore a neck brace before the next day's race. Various drivers, including Senna, criticized the poor condition of the circuit. During qualifying for the
Belgian Grand Prix, French driver
Érik Comas crashed heavily and Senna was the first to arrive at the scene. Senna could hear that the stricken car's engine was revving at max RPM, and with a possible fuel leakage that could cause an explosion at any moment. Disregarding his own safety, he exited his car and ran across the track to help the Frenchman. His actions were applauded and seemed to soften his hard-nosed image.
1993: Final wins and last season at McLaren from the back of the field to fourth at the
1993 German Grand Prix. A free agent for , Senna offered to drive for Williams for free. However,
Alain Prost, who still had ill will against his former teammate, had already joined the team conditional on not being paired with Senna. Senna publicly accused Prost of cowardice, although the racing press noted that in , Senna had done the same thing to
Derek Warwick. Senna declined a drive from Ferrari, Without Honda, McLaren was left with a customer supply of
Ford engines, which were two specifications behind
Benetton's Ford works engines and 50-80 horsepower behind Renault. However, Senna was heartened by the
McLaren MP4/8, which implemented technological upgrades, including an updated active suspension system. Senna asked to switch to the
Chrysler-backed
Lamborghini V12 engine in midseason, He won his second after Prost, who had been dominating the race, spun out in the rain; Senna's pass on
Damon Hill for the lead was described as "the man at his most brilliant." The next race, the European Grand Prix at
Donington Park, has been described as one of the greatest races in Senna's career. In fast-changing and rainy conditions—Prost's seven pit stops set a Formula One record—Senna overtook four drivers on the first lap and eventually lapped all but second place. He also won his record-breaking sixth win at round six in
Monaco, breaking a tie with
Graham Hill at five, after polesitter Prost was handed a ten-second stop-go penalty for jumping the start. After Monaco, Senna unexpectedly found himself on top of the drivers' standings. However, he was only five points ahead of Prost. Senna's season was hampered by mechanical failures in
Imola,
Canada,
Britain,
Hungary, and
Portugal. Prost took his fourth world championship, with Senna as runner-up.
Jean Todt recalled that Senna sought a seat at Ferrari for the 1994 season, during the Italian Grand Prix at Monza in September. Todt told Senna he would not break his contracts with Berger and
Alesi. In mid-October, Senna signed with Williams to replace the retiring Prost for 1994. However, at the following race, the , Senna got into a heated argument with
Jordan's
Eddie Irvine (a backmarker who had tried to block Senna from lapping him) and eventually tried to punch Irvine in the head. He also turned down Prost's suggestion of a conciliatory gesture. After deliberations, the FIA limited Senna's punishment to a six-month suspended race ban (i.e., probation) for 1994, explaining that Irvine had provoked Senna on track and Senna had a "very positive attitude" with the tribunal. Senna's minimal punishment received some criticism, as the FIA had been threatening to ban Prost for four races for criticizing the FIA. Senna surprised the Formula One community by pulling Prost onto the top step of the podium to celebrate the Frenchman's retirement.
Williams (1994) was the last Formula One car raced by Senna. With Prost out of the picture, Senna joined Williams for . He was reportedly paid a $20 million salary. Although Williams remained the premier team in Formula One for several more years, it was particularly affected by the FIA's 1994 ban on electronic driver aids like active suspension, anti-lock brakes, traction control, and launch control. Senna said that he had a "very negative feeling" about the
FW16. He added that "it's going to be a season with lots of accidents, and I'll risk saying that we'll be lucky if something really serious doesn't happen." Before round three at
Imola, Senna spoke with Ferrari's
Luca Cordero di Montezemolo about potentially moving to the Scuderia. Senna was particularly upset by rumors that
Michael Schumacher's
Benetton B194 was still secretly using the electronic driver aids. Following his retirement at the , Senna stood near the first corner to watch the cars, hoping to detect evidence of cheating. According to teammate
Damon Hill, Senna claimed that he heard "unusual noises from the engine" indicative of cheating. Senna took pole at the first three races but retired from each of them. At
Brazil, Schumacher took the race lead after passing Senna in the pits. Senna pushed hard to overtake Schumacher, but spun on lap 56, forcing a retirement. Senna took pole again at
Imola but
fatally crashed during the race. Schumacher won his first Drivers' Championship and dedicated it to Senna. ==Death, state funeral and reaction==
