The Japanese car giant has boosted the number of senior pan-European marketers reporting to Mario Canavesi, senior vice-president of sales and marketing for Nissan Europe.
As part of the reorganisation, Volker Brien moves from his role as brand director at Renault Nissan Netherlands to take the number two role under Canavesi, as vice-president of sales and marketing for Europe.
Brien replaces Philippe Geffroy, who has moved to a sales and marketing role at Nissan in Mexico.
Nissan Italy managing director Giuliano Musumeci Greco becomes vice-president of benchmarking, sales and marketing for Europe, while UK managing director Brian Carolin becomes vice-president of sales operations for Europe.
Bill Bosley, who joins from Nissan North America, will replace Carolin in the UK.
The restructure follows the 14.4% sales increase last year, when the company sold 542,292 units.
Its success was largely due to sales of the Micra, but its X-Trail and 350Z models also had a successful 2003.
A spokesman said Nissan Europe anticipates the same levels of sales for 2004. The Micra was Nissan's biggest launch of 2003 and was promoted by a TV campaign by Paris agency TBWA\G1.
The ads, directed by David Lynch, asked consumers 'Do you speak Micra?' and featured words shunted together to form new words that express the car's qualities - such as 'spafe', made up out of 'spontaneous' and 'safe'.
This month, the marque launched another wave of pan-European TV ads for the Micra and the 350Z.
Nissan is performing well in the UK. It has a 4% share and last year its total sales were up by 5% to 105,798, according to the Society of Motor Manufacturers and Traders.
The figure compares favourably with the 0.6% sales rise experienced by the overall market.
