Audi S line Logo

S line is a trim specification that is offered on many Audi models. Whilst the individual S line parts and components are designed and manufactured by quattro GmbH, Audi "S line" cars are still manufactured in the same AUDI AG factories, on the same production lines as their related models with differing trim levels. Cars with "S line" trim should not be confused with high performance "S" and "RS" models.
