Nelson Piquet made it two wins in eight days at the 1984 Detroit Grand Prix. Martin Brundle crossed the line just behind him after a superb recovery, although Tyrrell’s later exclusion changed the official podium to Nelson Piquet, Elio de Angelis and Teo Fabi.

Championship background
Alain Prost arrived at round 8 leading the 1984 F1 World Championship on 32.5 points, with Niki Lauda on 24. McLaren – TAG headed the constructors’ standings after the preceding race with 56.5 points.
Race entries
Patrick Tambay returned to Renault after missing the Canadian race, while Teo Fabi resumed his Brabham seat and Jonathan Palmer returned to RAM. A shortage of Hart engines forced Spirit to fit a Cosworth engine for Huub Rothengatter. He was ultimately the only non-qualifier.
Friday Free Practice
Friday’s running exposed the difficulty of Detroit’s bumpy, narrow circuit. Derek Warwick damaged his Renault in an impact that renewed concern about protection around the drivers’ feet. The frequent contact with barriers made preparation as much a matter of keeping a sound car available as finding the ideal balance.
Friday Qualifying
Nigel Mansell was fastest on Friday, showing his confidence around Detroit. Niki Lauda’s time was disallowed because his rear wing exceeded the permitted width, leaving him dependent on the second session.

Saturday Free Practice
The teams continued refining their cars on Saturday as the circuit became quicker. Toleman and Tyrrell both had accident repairs to manage during the meeting, while Williams struggled badly for pace. Nelson Piquet’s confidence in the spare Brabham grew, providing a useful fallback for a weekend in which the walls offered little forgiveness.
Saturday Qualifying
Nelson Piquet took pole with 1:40.980 despite his engine developing a problem near the end of the lap. Alain Prost qualified second and Nigel Mansell third, followed by Michele Alboreto. Niki Lauda recovered only to tenth, while Huub Rothengatter missed the grid.

Sunday warm-up
An overnight storm washed the circuit before Sunday’s warm-up, changing the surface again. De Elio de Angelis suffered engine trouble and took the spare Lotus for the race. The abrasive conditions made tyre durability a major concern, with several teams considering how to avoid an expensive extra stop.

What happened in the 1984 Detroit Grand Prix?
A collision at the first start eliminated Marc Surer and forced several drivers into spare cars for the restart. Nelson Piquet then led cleanly, while Nigel Mansell challenged before gearbox trouble ended his race. Attrition steadily removed other contenders, including Michele Alboreto, Derek Warwick and Keke Rosberg.
Brundle worked his naturally aspirated Tyrrell through the survivors and passed de Elio de Angelis for second. Nelson Piquet eased his pace late in the race, allowing the gap to shrink dramatically, but remained in control at the finish. Brundle crossed the line less than a second behind.
Post-race scrutiny of Tyrrell’s car led to the investigation that ultimately removed the team from the championship. The revised result gave second to de Elio de Angelis and third to Fabi, with Alain Prost fourth and Jacques Laffite fifth. No sixth-place point was awarded because no further eligible car had completed sufficient distance.
After the race, Alain Prost headed the drivers’ standings with 35.5 points, followed by Niki Lauda on 24. McLaren – TAG led the constructors’ table on 59.5, with Lotus – Renault on 27.
