Ross will lead development of Aston Martin’s engines, gearboxes and electrification, bringing with him 25 years of engineering experience - 16 of which were in top-ranking positions in Italy, including at Ferrari’s Formula 1 team.
He also spent time at Ford and engineering firm FEV earlier in his career. Ross is leaving his role as Maserati’s head of advanced powertrains, a position he has held since 2014, to join Aston Martin.
Aston Martin chief technical officer Max Szwaj said: “We are delighted to welcome Joerg to the Aston Martin team. His considerable experience and knowledge will prove invaluable for the engineering team as we prepare the business for the next generation of Aston Martin products."
Aston Martin will launch its first electric production car, the RapidE, in two years' time. That car was previewed in a prototype in 2015 and was confirmed for production earlier this year. The RapidE is expected to produce up to 1000bhp from a four-motor set-up. Ross will take a leading role in the production car’s powertrain development.
