Car & Driver's Mike Dushane nabbed a one-on-one interview with Audi AG head of development Michael Dick. It's a great article and a must-read, but here're the most interesting portions according to us...<p><b>Next-Gen S5 and S4</b><br>We're calling it B9, but it'll be an evolution of Audi's MLB (modular longitudinal architecture). Dick told C&D that the next-gen cars will make heavy use of Audi's aluminum space frame tech as seen in the A8 and TT to drop weight by 20%. That's good for handling and efficiency, but will also allow Audi to offer smaller engines (30% less displacement says the C&D piece) - think turbocharged 4-cylinders.<p>Michael Dick told C&D that Audi is currently testing a next-gen mule that weighs 880 lbs less than the current car.... roughly 3000 lbs... about 100 lbs. lighter than a last-gen Subaru Impreza WRX STI. The Audi board member also says the mule will lap the Nurburgring 8 seconds faster than the current S5. <p>For those mule-spotters in Nurburg, the article also mentions the car is wearing the current S5's bodywork.<p>The S5 is set to debut in 2014 according to the article.<p><b>C7 A6</b><br>If the article is right, then the next-gen A6 will also utilize an aluminum space frame. <p><A HREF="http://www.caranddriver.com/reviews/hot_lists/high_performance/german_performance/2014_audi_s4_and_s5_massively_lighter_to_use_turbo _fours_car_news" TARGET="_blank"><b> Full Story </b></A>
