Callum, 42, has been with Mazda's majority shareholder, Ford Motor Co., since 1995. Most recently he has been the designer in charge of light trucks such as the Ford Windstar and Mercury Villager as well as Ford Super Duty pickups and the Ford Excursion.
The Friday, Sept. 7, announcement came as Mazda prepared to unveil the redesigned 626 this week at the Frankfurt Motor Show.
That car and other Mazdas on the horizon, such as the 2003 RX-8 and the 2004 Miata and Protege, have come from a team of six Mazda design leaders, each in charge of a family of vehicles. Those designers have reported to Tom Matano, who has been the acting head of design.
With Callum's arrival, Matano will continue as a design leader.
Callum's career in car design started in 1982. After six years with Chrysler UK and then Peugeot-Citroen PSA, he joined Ghia S.p.A as a consultant designer.
His appointment brings designer ties to two Ford brands. Callum, who is British, is the brother of Jaguar's design chief, Ian Callum.
