Show Review: Design LA

Design LA, the automotive design conference that incorporates the Design Challenge competition, has announced its winners, during this year's LA Motor Show. Chuck Pelly, who set up Design LA last year, introduced the event and the judges for the Design Challenge: Tom Matano , Director, Academy of Art University; Imre Molner, Dean, College of Creative Studies; Steward Reed, Chair, Transportation Design, Art Centre College of Design; and Bill Van Amburg, Senior Vice President, Calsart. This year's nine competition entries had a brief to deliver a 100 percent recyclable, five-year lifespan vehicle with 'accoutrements that add fun or function to represent California's unique green lifestyle.' The Acura FCX 2020 Le Mans is a Le Mans-style race car concept notable for its enclosed wheels and motorbike style forward-inclined driving position between the front wheels (which can just be made out in the translucent illustration shown here).

BMW M550d xDrive confirmed. X5 M50d & X6 M50d likely

BMW M550d xDrive arriving March 2012 (M5 pictured) We’ve been talking about the BMW triple-turbo diesel for a long time. As far back as Spring 2009 we reported BMW were working on a triple-turbo diesel, which we expected to see the light of day first in the BMW X5. It took more than two years for BMW to catch up with our story on the triple-turbo diesel, but we finally had BMW man  Brian Watts confirming the new diesel, but that it would turn up as the M550d.
