The Turbo Years In 1966, when the formula was changed allowing for 3 liter engines a provision was made for 1.5 liter supercharged engines. With no takers amongst the current engine suppliers and the tremendous success of the Ford-Cosworth it was left to an outsider, yet one with a history that traced back to the first Grand Prix to show a third way. Renault had been trying to win Le Mans with a turbo-charged engine but was suffering from cracked pistons. Bernard Dudot was sent to Garrett AiResearch to study the fine art of turbo-charging. In 1979 the Renault turbocharged engine found its way into a Grand Prix car. They were soon joined by BMW and the turbo era was dawning. It was thought by some that turbocharged engines would allow large manufacturers to leapfrog the smaller British teams and their acknowledged leadership in chassis design.
Rules changes for 1982 banning the use of movable skirts forced teams to reduce ground clearances to around 25mm in conjunction with an almost total lack of suspension movement. The drivers were now experiencing cornering forces up to 4gs at some circuits. Double World Champion Niki Lauda was lured from retirement by a barrel full of Marlboro cigarette money to join John Watson at McLaren. Alan Jones went the opposite direction and quit Formula 1 opening a seat at Williams for Finn Keke Rosberg. The third rival for the title of the previous year, Carlos Reutemann also retired, this time after the first two races. The turbos of Ferrari, Renault and now Brabham dominated the opening race at Kyalami with Prost taking the flag. The British teams continued to fight what would become a losing battle against the turbos. Brabham, having access to both turbo and Cosworth engines tried to straddle the middle. Piquet in a Brabham took Brazil but only after temporarily reverting to a normally-aspirated engine. The turbo cars had a clear advantage on the faster circuits but their continued turbo lag proved a handicap on circuits with a lot of corners. Only after Spa was it dragged firmly into the turbo camp by its erstwhile engine supplier BMW.
Almost as an afterthought the race was won by John Watson for McLaren. At Monaco it rained but Riccardo Patrese was able to stay on the track and score his first victory. Watson and Piquet took the next two races, Detroit and Canada, respectively. By the German Grand Prix the title race was between Pironi and Watson only to have the Ferrari driver suffer career ending injuries during practice. The Swiss Grand Prix which was held in Dijon, France was won by Rosberg who now found himself in the championship's lead. The season ended at the lamentable Las Vegas, US Grand Prix - West and though the race was won by Michele Alboreto in a Tyrrell the title went to Keke Rosberg. The battle between turbo-charged and normally aspirated cars were now dead even at 8 victories apiece. A turbo-charged car had yet to take its driver to the World Championship. That was to change in 1983. Two new manufacturers introduced turbo-charged engines - Honda and TAG-Porsche. 1983 also saw the effective banning of ground effects with the requirement for flat bottoms. The first half of the season saw Ford-powered victories at Long Beach, Monaco and Detroit before the turbos took over for good. The 1982 season had been a development season for Brabham and new engine supplier BMW, but when the car came right Nelson Piquet was the man to bring it home winning two of the last three races and claiming his second World Championship. The eighties now had their second double World Champion but there seemed to be something missing that year.
