Porsche Engineering

Porsche Engineering (Porsche Engineering Group GmbH) was established in 2001 as a wholly owned subsidiary of Porsche AG, with headquarters in Weissach, and traces its history back to 1931 when Porsche created its first engineering office subsidiary. Porsche Engineering Group has been re-organized into Porsche Consulting (subsidiary of Porsche AG) and Porsche Engineering (subsidiary of Porsche SE).

Porsche Engineering has offered consultancy services to various other car manufacturers for many years including Audi, Mercedes-Benz, Opel, Studebaker, SEAT, and Zastava Automobiles. Since 2012 the company has managed the former Fiat owned Nardò Ring in Italy.

Note: Mercedes-Benz OM602 engine was designed by Ferdinand Piëch after he left Porsche.
