The Birmingham-based agency’s automotive PR team will support Volkswagen’s in-house press office, reporting directly to the brand’s head of press and PR, Pietro Panarisi.
Cogent won the work through a pitch and will be led by PR director Tim Gearey, who worked with Panarisi at Skoda UK.
The new brief was created shortly after the arrival of Panarisi to the role last June.
He said: "Cogent demonstrated a thorough understanding of the automotive business and this, along with its experience in the industry, resulted in a successful pitch. Its expertise in the automotive sector will be paramount in helping us raise our profile within specialist trade media."
