Jerome Guillen, a key Tesla executive who worked on the development and final production of the Tesla Semi, has left the company, the automaker said in a filing to the US Securities and Exchange Commission on Monday.
Guillen’s departure comes three months after he was transferred from the post of president of automotive, which included overseeing Tesla Semi to a less-responsible role as head of heavy duty trucking. Guillen headed Tesla’s entire automotive business from September 2018 to March 2021.
Guillen had a decade-long career at Tesla and held several roles at the company. He started at Tesla in 2010 reporting directly to CEO Elon Musk as Program Director of the Model S and was soon given more responsibility, including VP of Vehicle Engineering. He was later appointed president of Automotive before becoming president of Heavy Duty Trucking in March 2021. Guillen is a former Daimler executive who was responsible for the development of the company’s new generation of Class 8 trucks.
The Tesla Semi, a battery electric semi-truck, is still in development. The company first revealed the Tesla Semi in November 2017. It was slated to go into production by 2019, but has been pushed back. It is unclear whether Guillen’s departure will delay the Semi further.
In January, Tesla CEO Elon Musk said during the company’s 2020 Q4 earnings call that all engineering work on the Semi has been completed and deliveries are expected to begin in 2021. The availability of battery cells was the only issue limiting production of the vehicle, Musk said at the time. Three months later, Tesla did not provide a progress report, except that the semi was in development.
Earlier this month, the company announced that the first Tesla Semi Megacharger would be installed at Frito-Lay’s Modesto, California delivery center. The MegaCharger charging stations will be able to service up to 100 Tesla Semi trucks.
Earlier this year it was reported that Tesla was building a new production line for its Semi models near its Nevada Gigafactory location, aimed at producing five semi-trucks per week.
