Wilcox will take up the role of vice-president marketing, Europe, from November and relocate to the Paris office.
He replaces Volker Brien, who is returning to Germany to take up another position within the company.
Nissan UK, which is hunting a replacement for Wilcox, appointed him as marketing director in October 2003. At the time, he replaced Simon Thomas, who became sales director.
Previously, Wilcox was Europe business manager for strategy and planning, based in Paris, where most of the marque's European advertising is generated.
As marketing chief, he was largely responsible for the 'original drama' campaign, created by TBWA\London. The promotion, which broke earlier this year, featured a short film, divided into 24 minute-long episodes, which ran in Sky One drama slots.
The ads, shot in the style of a road movie, featured various Nissan cars. They formed part of the firm's marketing strategy to create a series of executions that would intrigue the audience to the same degree as a TV series.
The company viewed the campaign as such as success that it launched a DVD featuring the executions.
