For Shapeway models, i work with Blender. This picture is on display at the official Mercedes Petronas F1 Site. And some more (5)! The biggest compliment i ever got! The car is a W125 Mercedes-Benz F1 car from 1937. In relation to the MB 2011 car, it's the second of it's generation. It's also going to be published in the next online BlenderArt magazine!
