The car was designed by Harvey Postlethwaite, previously responsible for the Hesketh 308 in which James Hunt won his first race. Hunt briefly drove WR7 for the Wolf team in 1979, before walking out of Formula One after the 1979 Monaco Grand Prix. Keke Rosberg took over his drive for the remainder of the season.
At the end of the 1979 Formula One season, Walter Wolf, owner of the team, pulled out of Formula One and sold the assets of his organisation to Wilson and Emerson Fittipaldi for the use of their Fittipaldi Automotive team. The WR7-9 series cars were raced as Fittipaldi F7s in the early part of the 1980 Formula One season by Emerson Fittipaldi and Rosberg.
