JCB Fastest Tractor

The project brief

The brief

WAE were approached by JCB to support the aerodynamic element of a bold new project; to deliver the aerodynamics to beat the world record for the world’s fastest tractor. The project was carried out on the standard JCB Fastrac model. The world record was recorded as an average speed over two 1 km runs and the aerodynamic development was carried out over 3 months.

The work

  • Streamlining the JCB Fastrac bodywork by the development of a Front Splitter, Belly Plate, and Rear Diffuser
  • Aerodynamic Development involving over 65 CFD Runs
  • Cooling System Analysis

The outcome

25% Reduction in Drag Over Standard Fastrac Tractor

Standard Cab 200mm lower and 300mm narrower to reduce Aerodynamic Drag

The vehicle hit 153.7 mph with an average of 135.1 mph

The previous record was beaten by over 50mph
