I must admit to pinching this quote from another site :'Just as you'd expect from Australia, the Elfin Streamliner combines way too much engine and barely enough car. ' It just seemed to appropriate to omit. The Elfin MS8 uses an 5.7 litre LS1 engine giving 330 BHP. That's just the standard offering though, you can have 450BHP if you must. It weighs 2,426 pounds (1100 kilos), so it has the power to weight of a supercar. This one was at the Phillip Island historic meeting in Australia in March 2007. I've never seen another one.
