Hall started his career as a journalist for Motor Trend.[3]
Hall's first blackboard sketch of a two-seater convertible car in the early 1980s resulted in him being offered a job by Mazda Motors although he has no formal engineering qualifications. Hall is considered to be the "biological father" of the MX-5 (known in the United States as the Miata), although he was not responsible for the engineering and styling work that brought it to production.[3]
After leaving Mazda, Hall continued his career as an automotive journalist in Australia.[4]
Hall lived in Malaysia from 2004 to 2011,[5] working for Proton as Head of product planning and programme engineering.[6]
In September 2014 Hall joined Geely, where it has been said he's been tasked to come up with an all-new mass-selling vehicle to hit the spot with western markets.[7] While he has not commented on what the new vehicle may be, he has said it will not be a front-engine, rear-drive sportscar.[8]
