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.

General Motors fires back at Volkswagen

General Motors issued a terse response this week to published comments by Volkswagen CEO Martin Winterkorn, who suggested to the German press that Opel could be sold to a Chinese competitor. Detroit-based GM called Winterkorn's comments “regrettable” and accused him of “fanning speculation.” Opel was nearly sold to Magna and Russian investors in the wake of GM's 2009 bankruptcy. But then-CEO Ed Whitacre and the corporate board reversed that decision, igniting controversy from German political and labor leaders who have long chafed under American oversight.

Junction auto-brake for next Volvo XC90

THE NEXT Volvo XC90 will be able to brake itself if its driver attempts to pull out in front of an oncoming car, as one of two world-first safety innovations. This auto-brake technology detects whether an approaching car is technically on a collision course and will hit the stoppers to prevent a possible accident. However, there is no mention of an increased risk of rear-end collisions where drivers following the XC90 might also accelerate, not expecting the Volvo to stop suddenly.
