Meanwhile, Zach Kirkhorn, the electric car maker’s chief financial officer, has been given the job title “Master of Coin.”
The two executives have, perhaps sensibly, decided to maintain their titles of CEO and CFO.
Musk’s coronation comes after two months of jostling for position as the world’s richest man with Jeff Bezos: he is presently $10billion off the Amazon founder’s $179billion fortune following a slip in Tesla’s share price, which is nevertheless up 530% over the past 12 months.
Kirkhorn has been a vocal advocate of Bitcoin on social media, and is believed to have been instrumental in the company’s push to buy $1.5billion of the cryptocurrency in January.
In a potentially more significant boardroom shift, Jerome Guillen has moved from being president of the group’s automotive operation to head up its growing truck division.
Guillen took over the car business two years ago after the scale-up to 5,000-units-per-week mass production of the Model 3 led to what Musk later called: “production hell”.
The new group is preparing to start deliveries of its first battery-powered lorry later this year.
It released a short clip of the “Semi” – which was first teased in 2017 but is not yet in production – in action on a racetrack last night.
The company said: “As Tesla prepares to enter the critical heavy trucks market for the first time, Mr Guillen will now leverage his extensive background in this industry to focus on and lead all aspects of the Tesla Semi program, including the related charging and servicing networks.”
