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 has expanded its branded ‘For Business’ Supercharger program that it launched last year, as yet another company is using the platform to attract EV owners to its business and utilize a unique advertising opportunity.
Francis Energy of Oklahoma is launching four Superchargers in Norman, where the University of Oklahoma is located. The Superchargers, which are fitted with branding for Francis Energy, will officially open tomorrow.
It will not be the final Supercharger location that Francis Energy plans to open, the company confirmed to EVWire.
Back in early September, Tesla launched the new “Supercharger for Business” program in an effort to give businesses the ability to offer EV charging at custom rates. It would give their businesses visibility and would also cater to employees or customers.
“Purchase and install Superchargers at your business,” Tesla wrote on a page on its website for the new program. “Superchargers are compatible with all electric vehicles, bringing EV drivers to your business by offering convenient, reliable charging.”
The first site opened in Land O’ Lakes, Florida, which is Northeast of Tampa, as a company called Suncoast launched the Superchargers for local EV owners.

The program also does a great job at expanding infrastructure for EV owners, which is something that needs to be done to encourage more people to purchase Teslas and other electric cars.
Francis Energy operates at least 14 EV charging locations in Oklahoma, spanning from Durant to Oklahoma City and nearly everywhere in between. Filings from the company, listed by Supercharge.info, show the company’s plans to convert some of them to Tesla Superchargers, potentially utilizing the new Supercharger for Business program to advertise.
Moving forward, more companies will likely utilize Tesla’s Supercharger for Business program as it presents major advantages in a variety of ways, especially with advertising and creating a place for EV drivers to gain range in their cars.
Tesla Cybercab is perhaps the most highly-anticipated project that the company plans to roll out this year, and as it is undergoing its testing phase in pre-production currently, there are some things to work through with it.
Over the weekend, an image of the Cybercab being loaded onto a tow truck started circulating on the internet, and people began to speculate as to what the issue could be.

The Cybercab can clearly be seen with a Police Officer and perhaps the tow truck driver by its side, being loaded onto, or even potentially unloaded from, the truck.
However, it seems unlikely it was being offloaded, as its operation would get it to this point for testing to begin with.
It appears, at first glance, that it needs assistance getting back to wherever it came from; likely Gigafactory Texas or potentially a Bay Area facility.
The Cybercab was also spotted in Buffalo, New York, last week, potentially undergoing cold-weather testing, but it doesn’t appear that’s where this incident took place.
It is important to remember that the Cybercab is currently undergoing some rigorous testing scenarios, which include range tests and routine public road operation. These things help Tesla assess any potential issue the vehicle could run into after it starts routine production and heads to customers, or for the Robotaxi platform operation.
This is not a one-off issue, either. Tesla had some instances with the Semi where it was seen broken down on the side of a highway three years ago. The all-electric Semi has gone on to be successful in its early pilot program, as companies like Frito-Lay and PepsiCo. have had very positive remarks.
The Cybercab’s future is bright, and it is important to note that no vehicle model has ever gone its full life without a breakdown. It happens, it’s a car.
Nevertheless, it is important to note that there has been no official word on what happened with this particular Cybercab unit, but it is crucial to remember that this is the pre-production testing phase, and these things are more constructive than anything.
Tesla analyst Andrew Percoco of Morgan Stanley teased the company’s dominance in its self-driving initiative, stating that its lead over competitors is “not even close.”
Percoco recently overtook coverage of Tesla stock from Adam Jonas, who had covered the company at Morgan Stanley for years. Percoco is handling Tesla now that Jonas is covering embodied AI stocks and no longer automotive.
His first move after grabbing coverage was to adjust the price target from $410 to $425, as well as the rating from ‘Overweight’ to ‘Equal Weight.’
Percoco’s new note regarding Tesla highlights the company’s extensive lead in self-driving and autonomy projects, something that it has plenty of competition in, but has established its prowess over the past few years.
He writes:
“It’s not even close. Tesla continues to lead in autonomous driving, even as Nvidia rolls out new technology aimed at helping other automakers build driverless systems.”
Percoco’s main point regarding Tesla’s advantage is the company’s ability to collect large amounts of training data through its massive fleet, as millions of cars are driving throughout the world and gathering millions of miles of vehicle behavior on the road.
This is the main point that Percoco makes regarding Tesla’s lead in the entire autonomy sector: data is King, and Tesla has the most of it.
One big story that has hit the news over the past week is that of NVIDIA and its own self-driving suite, called Alpamayo. NVIDIA launched this open-source AI program last week, but it differs from Tesla’s in a significant fashion, especially from a hardware perspective, as it plans to use a combination of LiDAR, Radar, and Vision (Cameras) to operate.
Percoco said that NVIDIA’s announcement does not impact Morgan Stanley’s long-term opinions on Tesla and its strength or prowess in self-driving.

And, for what it’s worth, NVIDIA CEO Jensen Huang even said some remarkable things about Tesla following the launch of Alpamayo:
“I think the Tesla stack is the most advanced autonomous vehicle stack in the world. I’m fairly certain they were already using end-to-end AI. Whether their AI did reasoning or not is somewhat secondary to that first part.”
Percoco reiterated both the $425 price target and the ‘Equal Weight’ rating on Tesla shares.
