The Birth of Ground-Effects Two major developments occurred during
1977, the Renault turbo made its debut at the British Grand Prix while the Lotus-Ford 78
debuted in Argentina. Both would effect racing for years to come. The Lotus was the first
successful implementation of "ground effects" - the ability to harness the air
that travels under the car. The idea had its origins in Land Speed Record cars back in the
30's, specifically the Auto Unions designed by Professor Eberan-Eberhorst which employed side skirts as well as a
shaped bottom supplying a venturi effect. In 1969 BRM experimented with various ground
effect principles. Later at Lotus Tony Rudd and Peter Write, who had worked together at
BRM further developed the concept along with Ralph Bellamy and of course Colin Chapman. Chapman took special pleasure in the multiple use
of components and the idea of using the air under the car found a willing champion. The
missing element in earlier models was the adoption of flexible side-skirts. But even with
skirts the amount of negative pressure was still quite small. Further tests were done on a
wind tunnel with a rolling road. Chapman surmised that reducing the ground clearance would
increase the pressure and further testing proved him right. Moving the nose airfoil closer
to the rode surface so that the gap was only four inches caused the "road"
surface to actually lift! The team would report their findings to Chapman each week and
would be directed to pursue different ideas. The first test of the car took place in
August 1976, when Gunnar Nilsson secretly ran the car at the Snetterton circuit. The car
was not raced that year so as to be able to spring it on the opposition the following
year. Sprung it was at the Argentine Grand Prix but so new was the concept that few
understood what it was that they were seeing.
The Belgian Grand Prix was held at Zolder this year but the conditions were the same, it rained. The first lap saw both front row cars, Andretti's Lotus and the Brabham of John Watson eliminated in a collision. Conditions did not improve much for the remainder of the race but Andretti's teammate Gunnar Nilsson won a popular victory coming from 3rd on the grid. At Monaco, Cosworth celebrated its 10-year anniversary when Scheckter scored the engine manufacturer's 100 World Championship win. Monaco also saw the debut of a young Italian driver by the name of Riccardo Patrese. Andretti left his rivals behind at the Swedish Grand Prix at Anderstop only to run out of gas two laps from the end giving the victory to Jacques Laffite in his Matra powered Ligier. Andretti turned the tables on his rivals when he stole a victory at the French Grand Prix when Watson's Brabham ran out of fuel.
The British Grand Prix also marked the debut of a young French-Canadian named Gilles Villeneuve driving a McLaren M23. With all of this the race was won by James Hunt. The German Grand Prix was moved to Hockenheim and won by Niki Lauda. Alan Jones driving a Shadow was the surprise winner of the Austrian Grand Prix while Niki Lauda continued to accumulate points with a second place. Lauda added a victory at the next race in Holland to give him a commanding lead while Andretti who had won three races was continually plagued by engine problems. Lauda also confirmed that he would be leaving Ferrari at the end of the year. Andretti won the next race in Italy but with Lauda's second place the championship was almost his. The clincher came at the United States Grand Prix won by James Hunt. Lauda refused to drive the two remaining races and Ferrari hired Gilles Villeneuve to finish the season. After victories by Hunt and Scheckter the season was finally over. It also marked the end of the line for BRM. The team from Bourne who last tasted victory in 1972 would be no more. New for 1978 was the Arrows team set up by Alan Rees, Jackie Oliver and ex-Shadow designer Tony Southgate. Their car was also a wing-car design though with some differences in side pod design. Ferrari with their new Michelin tires also scored several victories but the most striking car of 1978 must surly have been the Brabham-Alfa BT46 with its rear mounted fan for sucking air from the bottom of the car. The car caused a sensation at the Swedish Grand Prix where it scored a convincing victory. The celebrations in the Brabham team were short lived as the car was banned shortly there after. 1978 marked the second time an American would become World Champion but Andretti's title was forever marred by the death of his teammate, Ronnie Peterson at Monza. That accident effected this writer deeply and caused a break with Formula One that lasted for over ten years. Its still not easy writing about 1978 and hopefully this website's readers will allow the editor to continue onto 1979. In a decision that he would soon regret Carlos Reutemann left Ferrari for Lotus. He was replaced at Ferrari by Jody Scheckter who would be teamed with the hard charging Villeneuve. John Watson left Brabham for McLaren and his seat was taken in turn by the talented Brazilian Nelson Piquet. There was still a tire war going on between Michelin and Goodyear. Since Michelin only had to supply Renault as well as Ferrari their task was infinitely easier than Goodyear's. More and more teams were incorporating some type of wing-car design and with the softer tires, the better cars were now able to achieve cornering forces of over 3g as compared to 1g in the early sixties and .6 to .7g during the last front-engined decade of the fifties. According to legend The Tyrrell 009 was built around plans for a model Lotus 79 that the company had obtained from model manufacturer Tamaya! Renault began the season with last year's RS01 but with their ever more powerful turbocharged engine they were able to claim the first pole position of the season. By Monaco they converted to twin turbochargers in order to combat "turbo lag" and at the French Grand Prix they finally scored their initial victory. The first two races of the season, Argentina and Brazil were won by Jacques Laffite for Ligier. Ferrari took the next race in South Africa while Ligier bounced back in Spain, this time in the hands of Patrick Depailler. The Belgian Grand Prix was very competitive with the lead changing six times before Jody Scheckter in a Ferrari put his car ahead for keeps. Monaco was a battle between Scheckter and the Williams of Regazzoni but try as he might the Swiss driver could not pass the red car. Sadly this was the last Grand Prix for ex-World Champion James Hunt for after the race he quit the Wolf team and retired from racing. As noted earlier the French Grand Prix was won by Renault but it was the battle for second place between Villeneuve and Arnoux that captivated the fans. This late race duel with multiple passes, some in mid-corner added to the growing legend of the young French-Canadian driver. The fact that it had been for second place made it all the more remarkable.
The new decade saw a number of changes on the grid with the demise of Shadow, the merging of Wolf and Copersucar, and the comeback of Alfa-Romeo. Off the track there continued to be struggles between FISA and the Formula One Constructors' Association (FOCA). The major manufacturer's such as Renault, Ferrari (Fiat) and Alfa-Romeo tended to side with FISA while the British teams threw their lot with FOCA. This struggle also concerned turbo-charged engines championed by the former and sliding skirts and ground effects championed by the latter. The year saw victories by four different drivers in the first four races including Alan Jones for Williams, Rene Arnoux for Renault, Nelson Piquet for Brabham and Carlos Reutemann in a Williams before Jones won again in Spain. Spain also saw a standoff between FISA and FOCA that resulted in the withdrawal of Renault, Ferrari and Alfa-Romeo along with any championship points being awarded the victor. With the series in disarray it was left to Goodyear to force the combatants to the negotiating table. The French Grand Prix looked set for a French victory with Arnoux leading Jacques Laffite only to be caught by Jones. Jones won again in England while Laffite finished first in Germany. After a victory by Jean-Pierre Jabouille in Austria the next two races were won by Piquet. at Zandvoort. The title chase was now between two drivers, Australia's Alan Jones and the Brazilian Nelson Piquet. With Jones taking the title with a victory at Watkins Glen. 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.
