Audi made its big splash around the world thanks to its Quattro all-wheel-drive system that was a clever answer to inclement weather and a competitive edge on the track. The B7 A4 Quattro was introduced as the third to bear the A4 name and sported a respectable 2.0T engine that sent power to all four wheels through either a manual or automatic option which made the mid-size sedan appeal to daily commuters and performance enthusiasts alike.
