The boss of Aston Martin, Ulrich Bez, is expected to step down and take up a more ambassadorial role with the firm at the end of this year.

Bez, who will turn 70 in November, joined Aston as chief executive officer and chairman in July 2000, and stayed on following its sale to a Kuwaiti consortium led by David Richards in 2007.

He is best known for pushing the DB7 to success, overseeing Aston’s move from Newport Pagnell to Gaydon, where it built up a world-class manufacturing facility, and spearheading the launch of the modern range of Aston Martins.

An Aston spokesman refused to comment on the rumour, but Autocar understands that a new boss will be put in place this summer, giving him or her time to work with Bez during a transition period.

Aston’s chief platform manager, Chris Porritt, best known for his development role with the Aston One-77, is also believed to have left the firm to take up a leading role with Tesla.
