The Shadow DN3 was a Formula One car used by the Shadow team during the 1974 Formula One season. It also appeared twice during the early stages of the 1975 Formula One season in an updated form. Designed by former BRM engineer Tony Southgate, the best finish achieved in a DN3 was Jean-Pierre Jarier's third place at the Monaco Grand Prix.

Development[edit]

The Shadow DN3, designed by Tony Southgate, was a development of Southgate's earlier car for the Shadow team, the DN1. One of the problems of the DN1, excessive vibration, was eliminated with stiffening of the DN3 monocoque. The DN3 had a longer wheelbase and was also five kilograms heavier than the previous year's car.[2]

Racing history[edit]

For the start of the 1974 Formula One season, the previous year's DN1 was driven by new Shadow driver Jean-Pierre Jarier for the first two races of the year and was retired from both. Jarier drove a DN3 for the remainder of the season. Peter Revson, a race winner for McLaren had also joined the team and had use of the DN3 from the start of the season. The DN3 showed immediate promise with Revson qualifying it fourth and sixth respectively for the first two races of the year. However, he was killed in testing prior to the South African Grand Prix and Shadow missed the race.[3]

Brian Redman took Revson's place in the team from the Spanish Grand Prix for three races, with Swedish driver Bertil Roos taking over for his home grand prix. Tom Pryce, who had made his Formula One debut earlier in the year with Token Racing, then took over for the remainder of the season. Pryce finished 6th in the German Grand Prix to end the season with one point towards Shadow's total of with seven points. The other six points came from Jarier, who, despite the death of Revson, continued as lead driver. In Monaco, Jarier finished third (having qualified sixth) and followed this up with fifth at the Swedish Grand Prix.[2] The team finished in eighth place in the constructor's championship.[3]

Until the new DN5 became available for his use, Pryce used an updated DN3B for the first two races of the following season, without scoring any points.[2]
