Audi RS4 Avant (2012) first official pictures

This is the Audi RS4 Avant, a 444bhp super-estate. It's the Mk3 RS4 Avant, and it will only be available as an Avant (the first RS4 was an estate-only twin-turbo V6, the second a brilliant V8-engined rival for the M3 and available in saloon and Avant guises). Important things first – how much space does the Audi RS4 Avant have for my Labrador and luggage?

MIT develops self-transforming materials that behave 'like robots without robots'

A cross-disciplinary research lab at the Massachusetts Institute of Technology (MIT) has developed a suite of programmable materials, including carbon fiber, printed wood grain, textile composites, rubbers and plastics, that self-transform when exposed to an external stimulus. Director of the Self-Assembly Lab, Skylar Tibbits, presented a TED talk on 4D printing in 2013, where he demonstrated how a flat sheet of material could effectively build itself when exposed to water, like a robot without a robot. Following positive feedback from industries including aviation, automotive and manufacturing, his lab has been working on developing materials that change according to different activation sources, including heat, light, and air pressure, in addition to water – all of which have automotive relevance.

Video: Jaguar's Julian Thomson on the importance of design values

Jaguar's Head of Advanced Design, Julian Thomson, appeared at this month's PSFK Conference in London giving a talk on design values. Thomson's talk, ‘Concepting Dreams, Making Reality Happen', dealt with questions of creating a design story as well as how Jaguar uses the value of its heritage while keeping things original and new. Thomson – the man behind the 2010 C-X75 and the recently revealed F-Type – said, "You can't get a good design story if you don't look at your heritage, where you came from, where your values came from." He went on to discuss the ‘sad years of Jaguar', from around 1968 to 2004 where Jaguar was too timid to develop and "essentially made the same-looking car." He put this down to a reluctance on Jaguar's part to move too far away from its successful models and, quite interestingly, because "not only did we start doing market research, we started asking Americans what they wanted."
