A Tesla Model Y engineer, who suggested the heat pump’s inclusion, has left the company after ten years, his LinkedIn account said.
Joseph Mardall served as the Engineering Director for Tesla from April 2018 to January 2021 but has held several other roles with the electric automaker since joining the company in February 2011 as a Senior Thermal Engineer.
Arguably, Mardall’s largest accomplishment while working with Tesla was the groundbreaking Model Y heat pump, a system that was included in the all-electric crossover to handle cold temperatures and combat range loss due to winter climates. Mardall led three teams with 60 or more engineers responsible for developing new HVAC systems that would be compatible with electric vehicles. One solution was the heat pump, an idea that came from Mardall’s engineering teams and has been a big hit with proven success in the Model Y.
CEO Elon Musk even told Teslarati in March 2020 that the heat pump was “some of the best engineering I’ve seen in a while. Team did next-level work.”

Mardall is headed to Zipline as the Head of Engineering. He will be working with a team of engineers “to design and build the next generation of autonomous drones to provide every human on Earth with instant access to vital medical supplies,” his LinkedIn account says. He states that the highlights of his career at Tesla “included the ground breaking Model Y Heat Pump system and leading Tesla’s efforts to develop a ventilator.”
“After 10 wonderful years at Tesla, I’m super excited to start my next chapter as Head of Engineering at Zipline, working with a team of talented and committed engineers to provide every human on Earth with instant access to vital medical supplies. The next 5 years are going to change everything, and I can’t wait! We are hiring for all roles across engineering and I would love to hear from you – come fly with me!”
Interestingly, Mardall has some medical equipment development experience, even though his work before Tesla was at McLaren Racing. Mardall worked intensively on the Tesla ventilator developed by company engineers last year. As the COVID-19 pandemic raged on, Tesla was donating third-party ventilators to hospitals in need but decided to develop its own. The ventilator prototype that Tesla built was comprised completely of parts from the Model 3 sedan, including the dash screen to see measurements of patient vitals. Mardall was present in Tesla’s video of the ventilator, posted in April 2020.

It is unclear who Tesla will place in the Engineering Director Role currently. Mardall’s work at Tesla was innovative and crucial, and many Model Y (and Model 3 Refresh) owners will thank him every day for the duration of their ownership!

Tesla’s new Safety Report shows Autopilot is nine times safer than humans
Tesla released its Vehicle Safety Report for Q3 2025, and it showed that one crash was recorded every 6.36 million miles drive in which drivers were using Autopilot technology.
Tesla’s new Safety Report for Q3 shows Autopilot technology contributed to accident frequency that was nine times lower than the national average.
Tesla released its Vehicle Safety Report for Q3 2025, and it showed that one crash was recorded every 6.36 million miles drive in which drivers were using Autopilot technology.
This is a stark contrast from the most recent data made available by the National Highway Traffic Safety Administration (NHTSA) and Federal Highway Administration (FHWA), which shows there is an automobile crash approximately every 702,000 miles.

The figure for Q3 2025 is slightly lower than the one that Tesla released in Q3 2024, which eclipsed 7 million miles between accidents for drivers using Autopilot technology.
Over the past seven quarters, Q1 has been Tesla’s strongest showing with the Vehicle Safety Report, with Q4 being the weakest. This is usually attributed to weather and driving conditions deteriorating toward the end of the year.
Q1 2024 was Tesla’s best performance so far, with one crash every 7.63 million miles.
Autopilot and Full Self-Driving have been a major focus of Tesla over the past few years, and recent versions have improved on what has already proven to be an extremely safe way to travel, as long as it is used correctly.
Tesla’s Full Self-Driving (Supervised) suite is a suitable way to allow the vehicle to navigate through any traffic setting and has been widely effective for day-to-day travel. With the data Tesla gets from its use across its vehicle fleet, it gets more refined and more accurate with every passing mile.
The company has teased the potential for completely unsupervised Full Self-Driving releases in the future, but Tesla has to solve autonomy before it can offer anything like that to the public.

Back in July, Tesla officially registered its presence in the Moroccan market with the $2.75 million initial capital investment, according to The Habari Network.
The move marked a formal attempt at market entry for the EV maker, and it could signal even more opportunities through its other business operations, like energy.
Morocco is looked at as one of the countries in Africa that is most prone to transition toward EVs, as its government has focused on renewable energy and strategic investments in transportation.
It also has local production advantages, as Renault operates a plant in Morocco.
