The season proved to be one of the most dramatic and controversial on record. While Hunt's performances in the Hesketh had drawn considerable praise, there was some speculation as to whether he could really sustain a championship challenge. Now a works McLaren driver, he dispelled many doubters at the first race in Brazil, where, in a hastily rebuilt McLaren M23, he landed pole position in the last minutes of qualifying. Over the course of the year he would drive the McLaren M23 to six Grands Prix wins, but with superior reliability, reigning world champion and main rival Niki Lauda had pulled out a substantial points lead in the first few races of the season. Hunt's first race win of 1976, at the fourth race of the season, the Spanish Grand Prix, resulted in disqualification for driving a car adjudged to be 1.8 cm too wide. The win was later reinstated upon appeal, but it set the tone for an extraordinarily volatile season. At the British Grand Prix, Hunt was involved in a first corner incident on the first lap with Lauda which led to the race being stopped and restarted. Hunt initially attempted to take a spare car, however this was disallowed, and during this time the original race car was repaired, eventually winning the restarted race. Hunt's victory was disallowed on 24 September by a ruling from the FIA after Ferrari complained that Hunt was not legally allowed to restart the race.
