The microsite, which will be live for the next 12 months, has been launched as part of a multichannel brand awareness campaign.
Syzygy's brief was to emphasise Citroen's strong heritage and tradition of innovation, leading into a showcase of the brand's future through a story of evolution.
The site offers a timeline journey through Citroen's history, illustrating the different approach the brand has taken in marketing and products.
It highlights Citroen's 1922 Type C series, which was the first European design to be created for women drivers. It featured a central gear leaver and convenient electric starter, proving to be an immediate hit.
The site's visual look is designed to have an artisan and handcrafted feel with a clean and fluid interface. Interactivity and video are also major features.
Syzygy collaborated on the development of the microsite with design agency Pexton Searle.
Gareth Phillips, managing director at Syzygy, said: "Our work with Pexton Searle ended up influencing the advertising campaign. We were allowed to experiment, the client asked us explicitly to break the rules, they wanted users to explore and get involved in the story."
Ian Hughes, marketing director at Citroen, said: "At Citroen we have a wonderful story that we wanted to bring to life in an engaging and exciting way, a way that was truly different, and a way that was reflective our philosophy.
"Syzygy fully embraced the brief and really surpassed our expectations."
