( http://www.TFLcar.com ) Which is faster in a straight line...the all new Audi A6 or the newest version of the BMW 5 series. The 2012 Audi A6 is all new.  It comes to the United States powered by a supercharged 3.0 TFSI 310 HP engine. The 2011 BMW 535i is just one year old and can be had with a turbo-charged 3.0L that puts out 300 HP. In this video we test the Audi A6 versus the  BMW 535i in our Nose to Tush drag race to see which one is faster.  Both cars have all-wheel-drive and both cars have an 8 speed automatic transmission. So which one is faster? Watch the video to find out.
