Which company co-developed the Audi RS 2 Avant with Audi?

Porsche co-developed the Audi RS 2 Avant with Audi. The RS 2 was a joint engineering project based on the Audi 80 Avant, combining Audi’s quattro drivetrain and five-cylinder expertise with Porsche’s performance development and manufacturing work.

Introduced in 1994, the RS 2 became Audi’s first model to carry the RS designation. It was powered by a heavily modified 2.2-litre turbocharged inline-five engine producing 315 PS. Porsche upgraded key components, including the turbocharger, intercooler, fuel system and engine management, helping turn a practical estate car into a high-performance machine.

Although Audi supplied much of the vehicle’s underlying engineering, Porsche assembled the RS 2 at its Rossle-Bau facility in Zuffenhausen, Germany. The collaboration explains why the car has unusually strong Porsche links despite remaining an Audi model with permanent quattro four-wheel drive.

The RS 2 was produced in limited numbers from 1994 to 1995 and is widely regarded as the ancestor of Audi’s later RS performance estates. Lamborghini, Lotus and BMW were not the co-development partners for this landmark Audi model.
