The 1984 Dallas Grand Prix was a Formula One motor race held on July 8, 1984 at Fair Park in Dallas, Texas. It was the only running of the Dallas Grand Prix as a Formula One race, and the ninth race of the 1984 Formula One World Championship. The 67-lap race was held in very hot weather on a disintegrating track, and was won by Finnish driver Keke Rosberg, driving a Williams-Honda, with Frenchman René Arnoux second in a Ferrari and Italian Elio de Angelis third in a Lotus-Renault. Englishman Nigel Mansell took pole position in the other Lotus-Renault and led the first half of the race, before suffering a gearbox failure at the very end and collapsing from exhaustion while trying to push his car over the finish line. Summary Keke Rosberg of Finland won his only race of the season at the Dallas Grand Prix. The race was one of only two races in 1984 where both of the year's dominant McLarens driven by Niki Lauda and Alain Prost did not score (Belgium being the other), and gave Honda their first turbocharged Grand Prix win and also their first Grand Prix win since the 1967 Italian Grand Prix. René Arnoux's Ferrari was the only other car on the lead lap at the end after starting from the pit lane due to an electrical fault on the warm up lap, while Elio de Angelis came home third for Lotus. It was the only race of the season that cars using Goodyear tyres filled all three podium positions. Only 8 cars finished the race, due to crashes or engine failures in up to heat, and also the track was breaking up very badly, as in the 1980 Argentine Grand Prix. The event was conceived as a way to demonstrate Dallas's status as a "world-class city" and overcame heat, a disintegrating track surface and weekend-long rumors of its cancellation. The tight and twisty course was laid out on the Texas State Fair Grounds with help from United States Grand Prix West founder Chris Pook, and featured two hairpin curves. While the layout was seen as interesting and was generally well received by the drivers (though some thought one or two of the chicanes made it tighter than it needed to be), all had issues with the lack of run-off areas and the crumbling surface which during the race itself made the
