Keke Rosberg

 ( 1948 Births ) 

In a year where no driver won more than two races, with Scuderia Ferrari's season marred by the death of Gilles Villeneuve at Zolder and the career-ending injuries to Didier Pironi at Hockenheim, and the turbocharged Brabham-BMW and Renault cars suffering from poor reliability (and not helped by Brabham continually changing between the Ford V8 and the BMW turbo), consistency won Rosberg the Drivers' Championship. This was despite his Williams FW07C using the normally-aspirated Cosworth DFY V8 engine which was considered outdated and out-matched against the vastly more powerful turbo cars. Rosberg won the championship with a five-point lead over Pironi, who had missed the last four races of the season due to injuries sustained at the German Grand Prix. Rosberg's 1982 Championship proved to be the last World Championship win for the old Cosworth DFV engine which had been introduced to Formula One by Team Lotus in (the DFY was a development of the DFV). To celebrate the victory, Frank Williams gave Rosberg two days off from testing and allowed him to smoke in the team mobile home. As a result of winning just one race in his title winning season Rosberg equalled the record set by Mike Hawthorn in 1958 for the fewest number wins scored by a driver during a World Championship winning season, a record he still jointly holds with Hawthorn as of 2023.

Rosberg's post-championship years would be hamstrung by both uncompetitive chassis from Williams, and the powerful but unreliable Honda turbo engine. For his title defense in , Rosberg was again using the reliable Ford DFY V8. However, by this time, the reliability of the Ferrari, Renault and BMW turbo engines was starting to match their speed and power output. Rosberg still put his Williams FW08 on pole for the opening race of the season in Brazil (where he was disqualified from 2nd place because he was push started in the pits after he was forced to abandon his car in his pit bay due to a fuel vapor fire), and then won both the non-championship Race of Champions at Brands Hatch and in Monaco thanks to a choice of slicks at the start when all others started on wets, but it was increasingly obvious that without a turbocharged engine, results would be scarce. To that end, Frank Williams concluded a deal to run the Honda V6 turbo engine in his cars. Honda had come back into Formula One that year with the Spirit Racing team and results had been slow with unreliability, but they were enthusiastic about joining Williams who had a reputation as a Championship-winning team. Rosberg and teammate Jacques Laffite first got their Honda turbos in the season ending South African Grand Prix at Kyalami and immediately the new Williams FW09 was on the pace. Rosberg finished in 5th place to give him 5th place in the championship.

Despite the powerful Honda engines, Williams and Rosberg struggled in mostly due to the FW09B chassis not being rigid enough to handle the power delivery of the V6. The Finn managed to tame both the car and engine long enough to win the Dallas Grand Prix,Dallas Grand Prix, John Blakemore Photograph Collection, Revs Institute, Revs Digital Library. but his only other podium for the year was a second at the season opener in Brazil (the third time in succession he finished second in Brazil, but the only one from which he was not disqualified). After a frustrating year he finished the championship in eighth place with 20.5 points.

In November 1984 following the Formula One season, Rosberg, along with fellow Formula One drivers Niki Lauda (the 1984 World Champion), Andrea de Cesaris and François Hesnault, travelled to Australia for the non-championship 1984 Australian Grand Prix at the Calder Park Raceway in Melbourne. Rosberg managed to qualify 4th in his Ralt RT4 Ford BDA despite spending most of the day with fellow aviation enthusiast Lauda (his teammate for the race) attending an air show at the nearby Essendon Airport. After an early race dice with Lauda and a clash with Terry Ryan while lapping the young Australian which put him off the short 1.609 km (1.000 mi) circuit, Rosberg went on to finish 2nd behind the Ralt RT4 Ford of Brazilian driver Roberto Moreno who won his 3rd Australian Grand Prix in 4 years (having also won in 1981 and 1983).

would prove better for both Rosberg and Williams. The Finn had a new teammate in [[Nigel Mansell]] and the all [[carbon fibre]] Williams FW10 chassis was a big improvement over the FW09B. For the first few races the team used the 1984 engines until Honda introduced an upgraded version which improved power delivery, fuel economy and most importantly, reliability. Rosberg used the new engine to good effect, winning the Detroit Grand Prix and claiming pole in the next two races in France at the Paul Ricard Circuit and the British Grand Prix at Silverstone. Rosberg's pole-winning lap at Silverstone created history when he lapped the 4.719 km (2.932 mi) circuit in 1:05.591 for an average speed of 259.01 km/h (160.94 mph). This would remain the single fastest lap of a circuit in Formula One until broken by Williams driver Juan Pablo Montoya at the 2002 Italian Grand Prix at Monza.
     

Rosberg's fifth and final Grand Prix victory came at the 1985 Australian Grand Prix on the brand new Adelaide Street Circuit. As it was the final race of the season, it was also Rosberg's final race for Williams. Keke gave the winners trophy to his race engineer, Frank Dernie. The win enhanced Rosberg's reputation as a street circuit specialist, as four of his five championship Grand Prix wins (Monaco, Dallas, Detroit and Adelaide) had come on street circuits. Rosberg handled the 35Celsius better than most and won by 43 seconds from the Equipe Ligier Renaults of Jacques Laffite and Philippe Streiff.

Just as the Honda engine began producing regular results, Rosberg decided to leave Williams at the end of 1985 and signed for McLaren, winners of the 1984 and 1985 Drivers' and Constructors' championships. The Williams-Honda team would go on to dominate Grand Prix racing in and through .
