Four vehicle designs based on one concept sketch, trying to create a family of vehicles, retaining some of the same features and transposing them into alternative functions, in this case an MPV, a Heavy Duty 4x4, a Sports Coupe and a Micro/Smart Car.
I've included some 3/4 turnarounds and explanatory sketches I did to help someone translating the Micro into 3D, plus the original sketches and roughs that initiated the designs.
