The event, which will take place on 14 December, will be run by Smyle's three in-house services teams to manage and deliver the event for 1,200 delegates, including dealers and management from throughout the UK.
Smyle, which is working with Peugeot for the first time, will take care of online registration, on-site logistics, delegate management, scripting and show production.
Its technical department will design and produce the main plenary set, the reveal mechanisms for three new car models and all audio visual elements.
"This is a major win for us, as we were pitching against five of the most established agencies in the industry," said Rick Stainton, Smyle's managing director.
"It is a particularly important event this year as there is the introduction of the new Peugeot UK managing director to the dealers as well as the reveal of three very exciting new products."
