The new indy lights car is draft designed and the model is in the wind tunnel for testing. Everything is printed in miniature scale on an SLA printer (except for front and rear wings which are alum) The wheels are machined from alum and the 'tires' are actually carbon fiber with anti-skid painted on for tread.
The first prototype should be here in indy in June !
