VW to intro Passat BlueMotion Concept at Detroit auto show

While performance heads are anxiously awaiting the North American debut of the hot-heat Mk VII Golf R at the Detroit auto show, Volkswagen's Passat BlueMotion Concept offers never-before technology in the Yank/Canuck family sedan segment: a four-pot motor with cylinder deactivation. Based on the EA211 1.4L turbo motor we sampled last year in the Euro-market Audi A3 sedan, the Passat BlueMotion Concept's engine is capable of shutting down the middle two cylinders during cruise, and features the Jetta Hybrid's gearbox, a twin-clutch unit capable of decoupling from the engine during off-throttle coasting. In the Passat's application, the 1.4 puts out 150 hp and 184 lb-ft of torque; VW suggests its highway fuel economy will stand at 42 mpg.

Saab 9-4X: First 9-4X rolls out

The Saab 9-4X Production Car rolls out of GM's plant in Mexico I seem to remember we did a similar headline to ‘Saab 9-4X Rolls Out’ almost exactly a year ago. But that headline – when Saab built 147 9-4X models at GM’s plant in Mexico - was for crash-testing and other pre-production requirements. This roll out of the 9-4X is the real deal.

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.
