Other than the R8, the B8 RS5 was the most formidable in Audi’s lineup. With a massively powerful supercharged V6, all-wheel-drive, and the 7-speed S-Tronic transmission, the RS5 carried all of Audi’s greatest hits to help rocket it to the front of any pack on the street or track. If you are one of the lucky few who own one of these, you likely need to keep it in peak form and probably have a few upgrades in mind.
