1975 saw a chicane added to Woodcote to slow cars going through the very high-speed corner; and this was another race of variables as a rainstorm hit the track and a number of drivers including Scheckter and Briton James Hunt hydroplaned off the track at the same corner; Fittipaldi won the race after it was called short. 1976 also saw changes to Brands Hatch including making the fearsome Paddock Hill bend a bit tamer and South Bank corner more of a left-hand apex rather than a long hairpin. This race proved to be very controversial; as home favourite Hunt won the race but was later disqualified following a protest from Ferrari and other teams about Hunt not completing the first lap of the race; and the victory went to second-placed Lauda. 1977 saw Hunt take victory without any controversy and when F1 returned to Silverstone two years later, Australian Alan Jones lapped the circuit more than 6 seconds inside the lap record in his ground-effect Williams. His teammate Clay Regazzoni won the race, Williams's first F1 victory. 1980 saw Jones win after the Ligiers of Jacques Laffite and Didier Pironi retired; and 1981 saw French rising star Alain Prost thoroughly dominate the first part race in his Renault; and there was an accident involving Canadian Gilles Villeneuve at the Woodcote Chicane which held up Briton John Watson; but Watson passed several cars and won the race; the first for a car with an all-carbon fibre chassis. 1982 saw polesitter Keke Rosberg having to start from the back due to problems with his Williams and he began a charge that brought him far up the field; but he retired, and there was another spectacular showing from Briton Derek Warwick in his underfunded Toleman; he managed to pass Pironi for 2nd, but he also retired with a broken driveshaft; the victory went to Austrian Lauda.
