In the midst of the 2012 Detroit Auto Show previews, Lexus has thrown out its first teaser image of a new Sport Concept scheduled to be revealed on one of the two press days in Detroit. This sporty new concept is said to showcase the brand’s new design direction which will hopefully eliminate the stuffiness associated with Toyota’s luxury brand. The teaser image is just that; a big, fat tease. However, we do see a bit of an aggressive line in the design, along with a slender headlight and a large air intake. There also seems to be design elements taken from the GS sedan unveiled earlier this year, which may mean this could be a preview of the new generation IS. Then again, the SC just performed a disappearing act a couple of years ago and Lexus was already rumored to be working on a more powerful successor. The new sport concept was designed by Calty, the company’s design studio in Newport Beach, California. Its official details will be released on January 9, 2012, so stay tuned!
