The Audi A4 has been in production since 1994 and has gone through five generations of innovation to the present day. It is available in sedan and “Allroad Quattro” body types. The sedan body types come in A4 and performance S4 packages, which offer a difference of about 101 horsepower and at least $14,200. The “Allroad Quattro” is designed for those that often find themselves on rough terrain, featuring higher clearance and increased cargo capacity.
