Tesla’s Model 3 Heat Pump is a game changer compared to its old system
Tesla’s addition of a Heat Pump to its 2021 Model 3 was installed with the intention of bringing owners of the company’s most affordable vehicle more range and more efficiency. Now that the newly “refreshed” Model 3 is making its way to owners, it is proving to be around three times more efficient than older builds of the vehicle.
A new video from well-known EV content creator and Tesla owner Bjørn Nyland showed that the heat pump gives owners around three times the efficiency compared to the previous HVAC system, which used a Positive Temperature Coefficient, or PTC system. This proves the addition of the heat pump was a strategy that will end up paying dividends to owners in cold climates, especially now as the Winter months are making their way to many owners across the U.S. and European markets.
Nyland compared a brand new 2021 Model 3 to his older version of the car, which does not have a heat pump equipped. Performing stationary tests to see which system was more efficient in heating up the vehicle during a chilly December night was the perfect test in Nyland’s eyes, and he came out of it with results that proved Tesla’s new system was superior to the old one.
Nyland used Camp Mode to test the efficiency of the two cars. Camp Mode maintains a temperature in the cabin while the vehicle is stationary and is ideal for those who sleep in their cars overnight. Because it uses energy from the car’s battery to maintain a comfortable cabin temperature, it was ideal for it to be used during this testing scenario.
After three hours of heating the cabin, both vehicles showed a drop in the state of charge, of course. However, the differences in the drop were night and day. The heat pump-equipped 2021 Model 3 had dropped only 3% in the three-hour span, while the sedan’s pre-heat pump variant had lost 10% of its battery.
The 2021 Model 3 has a 73.5 kWh battery pack with little-t0-no degradation due to its new powertrain that had only 65 kilometers on it. It used only 735 W of energy per hour, meaning 2,205 W were used over the course of the test.
The older Model 3 evidently did not have the efficiency that the new, heat pump-outfitted Model 3 did. After starting at 56%, the three hours of heating the cabin had brought the car’s state of charge down to 46%, meaning it was using roughly three times the amount of energy that the heat pump did. This equated to 2170 W of energy being used per hour by the old Model 3.
It is no secret that using a heat pump is more efficient than the past PTC HVAC system was. Tesla installed the heat pump in the Model Y and made it standard upon the car’s first deliveries in March 2020. Tesla decided to then make it standard in the Model 3 after refreshing the car in October 2020.

More tests are likely to come that will compare the two systems, but this test shows the efficiency differences in the two cars while heating up. If you’re spending nights in your Model 3, the new 2021 variant may be the way to go to alleviate any concerns about range diminishment overnight.
Nyland’s video comparing the two Tesla vehicles is available below.
Tesla has added the 15th automaker to the growing list of companies whose EVs can utilize the Supercharger Network this year, as BMW is the latest company to gain access to the largest charging infrastructure in the world.
BMW became the 15th company in 2025 to gain Tesla Supercharger access, after the company confirmed to its EV owners that they could use any of the more than 25,000 Supercharging stalls in North America.
Welcome @BMW owners.

Newer BMW all-electric cars, like the i4, i5, i7, and iX, are able to utilize Tesla’s V3 and V4 Superchargers. These are the exact model years, via the BMW Blog:
- i4: 2022-2026 model years
- i5: 2024-2025 model years
- 2026 i5 (eDrive40 and xDrive40) after software update in Spring 2026
- i7: 2023-2026 model years
- iX: 2022-2025 model years
- 2026 iX (all versions) after software update in Spring 2026
With the expansion of the companies that gained access in 2025 to the Tesla Supercharger Network, a vast majority of non-Tesla EVs are able to use the charging stalls to gain range in their cars.
So far in 2025, Tesla has enabled Supercharger access to:
- Audi
- BMW
- Genesis
- Honda
- Hyundai
- Jaguar Land Rover
- Kia
- Lucid
- Mercedes-Benz
- Nissan
- Polestar
- Subaru
- Toyota
- Volkswagen
- Volvo
Drivers with BMW EVs who wish to charge at Tesla Superchargers must use an NACS-to-CCS1 adapter. In Q2 2026, BMW plans to release its official adapter, but there are third-party options available in the meantime.
They will also have to use the Tesla App to enable Supercharging access to determine rates and availability. It is a relatively seamless process.

Tesla adds new feature that will be great for crowded parking situations
This is the most recent iteration of the app and was priming owners for the slowly-released Holiday Update.
Tesla has added a new feature that will be great for crowded parking lots, congested parking garages, or other confusing times when you cannot seem to pinpoint where your car went.
Tesla has added a new Vehicle Locator feature to the Tesla App with App Update v4.51.5.
This is the most recent iteration of the app and was priming owners for the slowly-released Holiday Update.
While there are several new features, which we will reveal later in this article, perhaps one of the coolest is that of the Vehicle Locator, which will now point you in the direction of your car using a directional arrow on the home screen. This is similar to what Apple uses to find devices:
Interesting. The location arrow in the Tesla app now points to your car when you’re nearby. pic.twitter.com/b0yjmwwzxN

In real time, the arrow gives an accurate depiction of which direction you should walk in to find your car. This seems extremely helpful in large parking lots or unfamiliar shopping centers.
Getting to your car after a sporting event is an event all in itself; this feature will undoubtedly help with it:
The nice little touch that Tesla have put in the app – continuous tracking of your vehicle location relative to you.
There’s people reporting dizziness testing this.
To those I say… try spinning your phone instead. 😉 pic.twitter.com/BAYmJ3mzzD

Tesla’s previous app versions revealed the address at which you could locate your car, which was great if you parked on the street in a city setting. It was also possible to use the map within the app to locate your car.
However, this new feature gives a more definitive location for your car and helps with the navigation to it, instead of potentially walking randomly.
It also reveals the distance you are from your car, which is a big plus.
Along with this new addition, Tesla added Photobooth features, Dog Mode Live Activity, Custom Wraps and Tints for Colorizer, and Dashcam Clip details.

All in all, this App update was pretty robust.
Tesla CEO Elon Musk shaded Waymo in a post on X on Wednesday, stating the company “never really had a chance” and that it “will be obvious in hindsight.”
Tesla and Waymo are the two primary contributors to the self-driving efforts in the United States, with both operating driverless ride-hailing services in the country. Tesla does have a Safety Monitor present in its vehicles in Austin, Texas, and someone in the driver’s seat in its Bay Area operation.
Musk says the Austin operation will be completely void of any Safety Monitors by the end of the year.

With the two companies being the main members of the driverless movement in the U.S., there is certainly a rivalry. The two have sparred back and forth with their geofences, or service areas, in both Austin and the Bay Area.
While that is a metric for comparison now, ultimately, it will not matter in the coming years, as the two companies will likely operate in a similar fashion.
Waymo has geared its business toward larger cities, and Tesla has said that its self-driving efforts will expand to every single one of its vehicles in any location globally. This is where the true difference between the two lies, along with the fact that Tesla uses its own vehicles, while Waymo has several models in its lineup from different manufacturers.
The two also have different ideas on how to solve self-driving, as Tesla uses a vision-only approach. Waymo relies on several things, including LiDAR, which Musk once called “a fool’s errand.”
This is where Tesla sets itself apart from the competition, and Musk highlighted the company’s position against Waymo.
Jeff Dean, the Chief Scientist for Google DeepMind, said on X:
“I don’t think Tesla has anywhere near the volume of rider-only autonomous miles that Waymo has (96M for Waymo, as of today). The safety data is quite compelling for Waymo, as well.”
Musk replied:
“Waymo never really had a chance against Tesla. This will be obvious in hindsight.”
Waymo never really had a chance against Tesla. This will be obvious in hindsight.

Tesla stands to have a much larger fleet of vehicles in the coming years if it chooses to activate Robotaxi services with all passenger vehicles. A simple Over-the-Air update will activate this capability, while Waymo would likely be confined to the vehicles it commissions as Robotaxis.
