Internally known as the "B7", Audi has finally released photographs and information on the new A4 and S4 models. The new car boasts a plethora of updates, technological additions and upgrades. Perhaps the most controversial element of the car's design will be the squared-off backside of new B7 sedans, along with the always controversial shield grille. The car will be officially shown at the Paris Auto Show later this month. Look for event coverage from Paris on this website.
