The 1984 Detroit Grand Prix was a Formula One motor race held on June 24, 1984 in Detroit , Michigan . It was the eighth race of the 1984 Formula One World Championship .

The 63-lap race was won from pole position by Brazilian driver Nelson Piquet , driving a Brabham - BMW . Englishman Martin Brundle finished second in a Tyrrell - Ford , less than a second behind Piquet, before the Tyrrell team were disqualified from the championship for various alleged rule infringements. Italian Elio de Angelis was thus promoted to second in his Lotus - Renault with another Italian, Teo Fabi , third in the other Brabham - BMW .

Pre-race

After breaking his leg at the Monaco Grand Prix three weeks before, and subsequently withdrawing from the next race in Canada , Patrick Tambay was back driving for the works Renault team. Mario Andretti , who had been called in as a possible replacement for Tambay in the race, was satisfied to spend the weekend as a spectator, watching his two sons run in the support races. Elsewhere, a lack of Hart turbo engines meant that the Spirit team were forced to modify their car to accommodate a natural...

Race report

Warm and sunny weather returned on Sunday after an overnight storm had washed the track clean, but at the green light, there was immediate chaos. Nigel Mansell had decided that he could get by Nelson Piquet off the grid and aimed his Lotus for the space between Piquet's Brabham and Alain Prost 's McLaren . He struck the back of Prost and bounced into the side of Piquet, sending the Brabham sliding to the outside wall of the track and into Michele Alboreto 's Ferrari . The Brabham's right rear wh...

Piquet, Alboreto and Senna took to their spare cars, but the Arrows team had none to offer Surer, so the Swiss driver was absent when the field reassembled on the grid. The second start came off without a hitch, as Piquet led from Prost and Mansell. At the end of the first lap, these three were followed by Alboreto, Eddie Cheever who had already gained three places, Derek Warwick , Elio de Angelis , Niki Lauda , Patrick Tambay and Ayrton Senna . Prost followed closely behind Piquet for the first...

Immediately, Mansell fought hard to catch the leading Brabham, taking over a second per lap off his lead. Piquet, it seemed, was driving just fast enough to stay in front, however, and Mansell was unable to get within striking distance. On lap 17, the Lotus slowed noticeably while entering the Atwater Tunnel, as he had lost second gear. Meanwhile, not only Prost, but the Renaults of Warwick and Tambay, and then Lauda were forced to stop for new tires, while Piquet was having no trouble at all wi...

The Tyrrell team, still loyal to the normally aspirated Cosworth-Ford V8 engine, were given no chance on the season of being competitive against the mighty turbos. Already, however, they had been in the points four times in seven races, and on a tight circuit, their lighter weight and lower horsepower combined to give much better tire wear. In Detroit, this allowed them to use the softer Goodyear compound, while all the others had to use the harder compound. Also, the compactness of the cars, in...

Bellof, however, suddenly ground to a halt on lap 34 when he struck the wall exiting the chicane before the pits. Then, just as Brundle was pitting for water ballast, Warwick set the fastest lap of the race and passed Rosberg and de Angelis on consecutive laps to take third place. About to set off after Alboreto, Warwick's Renault suddenly lost fifth gear, allowing de Angelis and Rosberg to repass him on lap 37. His gearbox completely expired on lap 41, and he became the eighteenth retirement of...
