I Draw Cars: The sketchbook that puts drawings into perspective

I Draw Cars is a project set up by Adam Hubers and Matt Marrocco – both CCS graduates – to encourage designers young and old to pick up their pens and practice that most basic yet powerful tool in their kit: sketching. Their new book features over 100 pages of perspective underlays – from basic views right up to complex three-point – to use as templates with which to practice. Each underlay is printed in non-photo blue, meaning it won't be picked up by a scanner should you choose to drop it into Photoshop.

Audi's electric R4 at the Detroit motor show 2010

This is Audi’s latest electric E-tron sports car, unveiled at today’s Detroit motor show. Or to give the concept its official name, this is the Audi E-tron Detroit Showcar. Catchy.

Design Review: Bertone Birusa concept

The new Birusa concept unveiled today shows Bertone returning to what they do best - a flamboyant showcar giving us a vision of how the high performance GT car (front engine, rear drive, two seats) could evolve stylistically in the near future. Based on a BMW Z8 aluminium chassis lengthened by 300mm, it's a refreshing piece of exuberance by the Italian company and a celebration of what they achieved in the 1960s and 70s. The wedge-shaped profile is characterised by a classic Bertone device - a dihedral-shaped side window with an undercut lower glass section, as featured on showcars such as the Boomerang and Carrabo.
