For the season, Hesketh Racing built a car, inspired by the March, called the Hesketh 308, but an accompanying V12 engine never materialised. Hunt's first test of the car came at Silverstone and found it more stable than its predecessor, the March 731. Hunt was retained on a £15,000 salary. The Hesketh team captured the public imagination as a car without sponsors' markings, a teddy-bear badge and a devil-may-care team ethos, which belied the fact that their engineers were highly competent professionals. In Argentina, Hunt qualified fifth and led briefly before being overtaken by Ronnie Peterson before Hunt spun off the track and eventually retired due to engine failure. In South Africa, Hunt retired from fifth place with a broken driveshaft. Hunt's season highlight was a victory at the BRDC International Trophy non-championship race at Silverstone, against the majority of the regular F1 field.
