8440 Formula Flash / Formula Indy Racer is a TECHNIC set of a racing car. The model features a V6 engine connected to a rear differential. The rear wheels have suspension and the front wheels can be steered. Note that for both models the steering is controlled with the steering wheel rather than a top gear method used in many other models. The alternate model is a hotrod.


  • The main model carries the logo of Octan, a fictional petroleum company in the LEGO universe.
  • Building instructions include a manual how to use 8720 9V Motor Set to get a motor-powered hotrod
