The Elfin MS8 Streamliner is a sports car, successor to the Elfin MS7, a Repco-Holden V8 powered sports racing car in which Elfin founder Garrie Cooper won the 1975 Australian Sports Car Championship, and Stuart Kostera won the 1976 Australian Tourist Trophy.

There are currently two Elfin MS8s in the UK for export evaluation[3] and an office has been set up in Chipping Norton, Oxfordshire.

The cars are distinguished by a special paint colour of 'Garrie Cooper Gold', a cabin hardtop and bonnet scoop and burgundy trim.

[3][5] In 2008, Elfin introduced a one-off promotional version of the MS8 Streamliner for the No Fear lifestyle brand whose products are sold exclusively at K-Mart stores throughout Australia.

The car, designed by HSV's Adam Dean Smith, has so far been displayed at the 2008 Melbourne International Motor Show and the Australian Grand Prix.
