Tesla Model Y heat pump functions explained and explored in Munro teardown
One of the Tesla Model Y’s most talked about features is its heat pump, which replaced the electric resistive heating system used in the Model S, Model 3, and Model X. In a recent video uploaded by Detroit automotive veteran Sandy Munro, he drew comparisons between the Model Y’s heat pump to the old air conditioning compressor that was included in the Model 3. More importantly, Munro also talked about why he prefers the new system to the former.
The heat pump was the brainchild of Tesla’s engineering team. Additionally, Munro stated in his recent teardown video that the new heat pump from Tesla can accomplish both air conditioning and heating. Interestingly enough, the component is independently mounted from other parts underneath the hood, allowing the unit to shake and move freely when it’s operating.
“That shake does not turn into a noise vibration and harshness that you’d find inside the car,” Munro says, as he suggested that mounting the pump to other portions of the vehicle’s system could cause an unfavorable noise. “This is right. This is the way to do it.”
Munro noted that the heat pump’s compressor “crushes” gas down and sends it out into a pipe that navigates away from the pump. The vehicle then makes a decision based on the climate control settings in the car. It will either go into an air conditioning condenser if the driver wants cold air, or straight into the cabin if the heat is turned on. While simple, Munro’s explanation shows the efficiency of the system. It simplifies the overall structure of the Model Y’s climate control, while providing a whole new way for Tesla to maximize the efficiency of the vehicle.
In a previous video from Tesla owner-enthusiast Andy Slye, he explained that while the electric resistive heating systems in the electric car maker’s previous vehicles have a 100% efficiency rate, heat pumps generally have a 300% efficiency rate. While this seems improbable, a heat pump can generate 3kW of thermal energy from 1 kW of power. This helps address the usual reduction of range experienced by Teslas in cold climates.
-->The new system could eliminate the worries of consumers who live in areas where extremely cold weather is anticipated during winter months. Cold air increases drag, and while the battery and cabin require warming, range drops, causing more frequent charging stops. But with a more efficient climate control system, this does not have to be the case.
As for Munro, he believes that a heat pump was indeed the right choice for the Model Y. “I think it’s a good idea to have the heat pump as opposed to the heaters and all the other stuff they had inside (the Model 3), so I’m pretty happy about that,” he said.
Tesla’s engineering team performed some of the best work yet with the Model Y, as per CEO Elon Musk. And if Sandy Munro’s ongoing teardown is any indication, it appears that the Tesla Mode Y is really the company’s most disruptive vehicle to date.

Tesla starts rolling out FSD V14.2.1 to AI4 vehicles including Cybertruck
FSD V14.2.1 was released just about a week after the initial FSD V14.2 update was rolled out.
It appears that the Tesla AI team burned the midnight oil, allowing them to release FSD V14.2.1 on Thanksgiving. The update has been reported by Tesla owners with AI4 vehicles, as well as Cybertruck owners.
For the Tesla AI team, at least, it appears that work really does not stop.
FSD V14.2.1
Initial posts about FSD V14.2.1 were shared by Tesla owners on social media platform X. As per the Tesla owners, V14.2.1 appears to be a point update that’s designed to polish the features and capacities that have been available in FSD V14. A look at the release notes for FSD V14.2.1, however, shows that an extra line has been added.
“Camera visibility can lead to increased attention monitoring sensitivity.”
Whether this could lead to more drivers being alerted to pay attention to the roads more remains to be seen. This would likely become evident as soon as the first batch of videos from Tesla owners who received V14.21 start sharing their first drive impressions of the update. Despite the update being released on Thanksgiving, it would not be surprising if first impressions videos of FSD V14.2.1 are shared today, just the same.
-->Rapid FSD releases
What is rather interesting and impressive is the fact that FSD V14.2.1 was released just about a week after the initial FSD V14.2 update was rolled out. This bodes well for Tesla’s FSD users, especially since CEO Elon Musk has stated in the past that the V14.2 series will be for “widespread use.”
FSD V14 has so far received numerous positive reviews from Tesla owners, with numerous drivers noting that the system now drives better than most human drivers because it is cautious, confident, and considerate at the same time. The only question now, really, is if the V14.2 series does make it to the company’s wide FSD fleet, which is still populated by numerous HW3 vehicles.

Waymo rider data hints that Tesla’s Cybercab strategy might be the smartest, after all
These observations all but validate Tesla’s controversial two-seat Cybercab strategy, which has caught a lot of criticism since it was unveiled last year.
Toyota Connected Europe designer Karim Dia Toubajie has highlighted a particular trend that became evident in Waymo’s Q3 2025 occupancy stats. As it turned out, 90% of the trips taken by the driverless taxis carried two or fewer passengers.
These observations all but validate Tesla’s controversial two-seat Cybercab strategy, which has caught a lot of criticism since it was unveiled last year.
Toyota designer observes a trend
Karim Dia Toubajie, Lead Product Designer (Sustainable Mobility) at Toyota Connected Europe, analyzed Waymo’s latest California Public Utilities Commission filings and posted the results on LinkedIn this week.
“90% of robotaxi trips have 2 or less passengers, so why are we using 5-seater vehicles?” Toubajie asked. He continued: “90% of trips have 2 or less people, 75% of trips have 1 or less people.” He accompanied his comments with a graphic showing Waymo’s occupancy rates, which showed 71% of trips having one passenger, 15% of trips having two passengers, 6% of trips having three passengers, 5% of trips having zero passengers, and only 3% of trips having four passengers.
The data excludes operational trips like depot runs or charging, though Toubajie pointed out that most of the time, Waymo’s massive self-driving taxis are really just transporting 1 or 2 people, at times even no passengers at all. “This means that most of the time, the vehicle being used significantly outweighs the needs of the trip,” the Toyota designer wrote in his post.
-->Cybercab suddenly looks perfectly sized
Toubajie gave a nod to Tesla’s approach. “The Tesla Cybercab announced in 2024, is a 2-seater robotaxi with a 50kWh battery but I still believe this is on the larger side of what’s required for most trips,” he wrote.
With Waymo’s own numbers now proving 90% of demand fits two seats or fewer, the wheel-less, lidar-free Cybercab now looks like the smartest play in the room. The Cybercab is designed to be easy to produce, with CEO Elon Musk commenting that its product line would resemble a consumer electronics factory more than an automotive plant. This means that the Cybercab could saturate the roads quickly once it is deployed.
While the Cybercab will likely take the lion’s share of Tesla’s ride-hailing passengers, the Model 3 sedan and Model Y crossover would be perfect for the remaining 9% of riders who require larger vehicles. This should be easy to implement for Tesla, as the Model Y and Model 3 are both mass-market vehicles.

Elon Musk and James Cameron find middle ground in space and AI despite political differences
Musk responded with some positive words for the director on X.
Avatar director James Cameron has stated that he can still agree with Elon Musk on space exploration and AI safety despite their stark political differences.
In an interview with Puck’s The Town podcast, the liberal director praised Musk’s SpaceX achievements and said higher priorities must unite them, such as space travel and artificial intelligence. Musk responded with some positive words for the director on X.
A longtime mutual respect
Cameron and Musk have bonded over technology for years. As far back as 2011, Cameron told NBC News that “Elon is making very strong strides. I think he’s the likeliest person to step into the shoes of the shuttle program and actually provide human access to low Earth orbit. So… go, Elon.” Cameron was right, as SpaceX would go on to become the dominant force in spaceflight over the years.
Even after Musk’s embrace of conservative politics and his roles as senior advisor and former DOGE head, Cameron refused to cancel his relationship with the CEO. “I can separate a person and their politics from the things that they want to accomplish if they’re aligned with what I think are good goals,” Cameron said. Musk appreciated the director’s comments, stating that “Jim understands physics, which is rare in Hollywood.”
Shared AI warnings
Both men have stated that artificial intelligence could be an existential threat to humanity, though Musk has noted that Tesla’s products such as Optimus could usher in an era of sustainable abundance. Musk recently predicted that money and jobs could become irrelevant with advancing AI, while Cameron warned of a deeper crisis, as noted in a Fox News report.
-->“Because the overall risk of AI in general… is that we lose purpose as people. We lose jobs. We lose a sense of, ‘Well, what are we here for?’” Cameron said. “We are these flawed biological machines, and a computer can be theoretically more precise, more correct, faster, all of those things. And that’s going to be a threshold existential issue.”
He concluded: “I just think it’s important for us as a human civilization to prioritize. We’ve got to make this Earth our spaceship. That’s really what we need to be thinking.”
