And more sketches from stages of Sketch Fighter SPD contest.
This is Saab concept in style of Saab PhoeniX concept

and this is VW ECO DakarRallyRacer buggy

and sketches of lightweight race car for LeMans 2025

These are sketches of VW iCON. It's my idea for Final round of Sketch Fighter SPD contest 2011. At that time I took third place.

Volkswagen iCON (Intellectual Construction) has adaptive elastic body. This car can move in three dimensions - earth, water and air with help of adaptive concentric wheels, water jets and aero engines.
