Tesla's vehicles are well-equipped for winter temperatures.

Teslas are among the most efficient electric vehicles in cold weather, according to a Recurrent study.
Cold weather often affects the range of electric vehicles due to two reasons. The colder weather alters the battery’s chemistry slightly; therefore, the range is decreased. The decreased range could mean some owners may have to modify their trips in the winter months when compared to warmer seasons.
Electric Vehicle Heaters
However, the biggest contributor to the decreased range for electric vehicles is due to heat production. Since electric vehicles are much more efficient than their internal combustion counterparts, they produce very little excess heat. Whereas heat is a byproduct of gasoline engines and can be funneled into the cabin to heat the passengers, electric vehicles need to produce additional heat to keep their passengers comfortable.
Resistive Heaters
This is typically done in two ways, either through electric resistance heating or through a heat pump. A resistive heater is like a space heater you may use at home. Electric current passes through wires causing them to heat up and the heat is then blown into the room.
Heat Pumps
Heat pumps are more complicated and work much differently than resistive heaters, however, they're also more efficient in most cases. They work by using outside air to warm up a refrigerant that is then pressurized to increase the temperature of the refrigerant. The refrigerant then flows to the inside of the cabin where the vehicle air passes through it, causing it to warm up and flow into the cabin. While heat pumps are much more efficient when compared to electric heaters, that efficiency is reduced the colder it is outside.
Which Teslas Have Heat Pumps
All newer Teslas use heat pumps instead of resistive heaters due to their increased efficiency. All redesigned Model S and Model X vehicles use heat pumps, as well as all Model Ys. However, some Model 3 vehicles between 2017-2020 use resistive heaters to warm the cabin, which makes them less efficient in colder months.
Find Out Your Type of Heater
If you don't know whether your Tesla has a heat pump or a resistive heater, you can find out by simply looking at your car's software. Your vehicle's heater type will be listed if you navigate to Controls > Software and then tap on Additional Vehicle Information.
Due to Tesla's unique heating system and its efficiencies, Recurrent found that Tesla vehicles hold some of the best range among electric cars. So, Tesla owners may not have to make as many modifications to their commutes. They're able to manage this because of their state-of-the-art battery technology, as well as using localized heating through heated seats, steering wheel, and cabin, as well as their advanced heat pumps.

RecurrentAuto
A new study published by Recurrent pulled data from 7,000 electric vehicles from the 14 most popular brands, including Audi, BMW, Hyundai, and Tesla. The data for each vehicle was gathered via the onboard telemetry and real-time usage. The vehicles were used in freezing (20-30 degrees F) temperatures and warm 70° F. As temperatures drop below 50° F, heat pumps start becoming less efficient.
Recurrent’s findings concluded that Tesla’s Long Range AWD Model Y and Model X 75D lost 15%, while the Long Range Model 3 with 75kWh battery lost 17%, and Model S P100D lost 19%. Compared to the Chevy Bolt, which lost 32%, and Ford’s Mustang Mach-E, which lost 30%, Tesla’s vehicles appear to be better equipped for cold weather. Unfortunately, Recurrent tested older Teslas that did not contain heat pumps, which means that Teslas numbers would have been even better if Recurrent used newer models. Even so, Tesla had some of the best performing vehicles.
Comparing Heat Pumps vs Resistive Heaters in Teslas
Powershare is a feature that is currently exclusive to the Cybertruck and one of the truck’s best selling points. With its massive 123kWh battery, the Cybertruck can supply power to your home when paired with a Tesla PowerShare setup. This system also includes automatic backup failover, ensuring seamless power during home outages.
Powershare Limitations
One major limitation has been that Tesla Powerwall owners couldn’t use the PowerShare feature due to software conflicts, which took a while to resolve.
However, the challenge wasn’t just software-related—Tesla also had to navigate several regulatory hurdles. A key issue was that homes with solar integrated into their backup solution couldn’t use PowerShare. This meant homeowners had to choose between powering their home with solar or their Cybertruck, rather than combining both sources.
Solar Update
Thanks to a recent update, PowerShare is now available for customers with solar in their backup circuit, allowing them to power their home with solar energy and even charge their Cybertruck during an outage—seamlessly and automatically.
Additionally, PowerShare is now enabled for customers with a backup switch, provided they are in an approved utility region.
Powerwall Update
PowerShare will be available to Powerwall owners using a Wall Connector Gen 3 or Universal Wall Connector starting in Q3 2025. While still a few months away, this is great news for Powerwall users looking to leverage the Cybertruck’s large battery as an extended backup power source for their homes.
Wall Connector Gen 3
Interestingly, Tesla has now enabled PowerShare for the Wall Connector Gen 3, a change that appears to be driven more by regulatory approvals than hardware or software limitations.
Currently, Tesla requires customers in the U.S. and Canada to use the Universal Wall Connector for PowerShare, even if they already own a Gen 3 Wall Connector. However, this policy will likely change in the coming months as the Gen 3 Wall Connector gains official support.
Author’s Note - Powershare Pricing
We’d love to see Tesla reduce the cost of PowerShare installation. The author received a quote for a home setup with two Wall Connectors in a standalone garage with its own breaker panel. Since the home already had an automatic Generac backup failover switch, much of the required electrical work was already in place.
Despite this, the final quote for installation came in just under $12,000 CAD (about $8,500 USD at the time). This covered only the installation of a Tesla Gateway, replacing a single Gen 3 Wall Connector with a Universal Connector, and some additional wiring. Even with the Foundation-Series discount of $3,500 CAD, it won’t be cheap to install.
While this update is a great step forward, Tesla needs to make PowerShare more accessible—both by expanding it to more vehicles and by lowering installation costs. It’s an incredibly useful feature that will help sell vehicles, but affordability remains an issue.
At the Cybertruck event, Tesla showed off the Cybertruck’s extended battery, an optional accessory permanently mounted to the truck’s bed. This was Tesla’s solution to keeping the truck price as low as possible while also giving owners a chance to get close to the truck’s original range of 500 miles.
The Range Extender is engineered to boost the Cybertruck's mileage substantially, increasing the truck’s total range by about 35%.
Tesla's Range Extender is a departure from traditional range-extending methods, often involving gasoline generators. Its design, occupying roughly a third of the truck bed, strikes a balance between added functionality and maintaining the truck’s cargo space. It addresses range limitations and makes the Cybertruck more suitable for towing and long-range trips.
Range / Battery Size
The Ranger Extender extends the Cybertruck total range by 120 miles (193 km). For the Cyberbeast, it’ll take the truck’s range from 320 miles up to 440, whereas for the AWD version, the range will be increased from 325 miles to 445 miles.
These are Tesla’s latest numbers, which have been reduced slightly from Tesla’s original estimates that the Ranger Extender pegged at adding 130 miles.
The Ranger Extender uses a huge 47 kWh battery pack, which explains why it takes up a significant portion of the truck’s bed. For comparison, Tesla’s Standard Range+ Model 3 has a 54 kWh pack, capable of driving about 260 miles.
Price
Though official pricing for the Range Extender has yet to be officially announced, it looks like it’ll be priced at a hefty $16,000 USD. The night the Range Extender was revealed, code was found on Tesla’s website that showed off the $16,000 price tag. However, it’s not clear whether this price was a placeholder or if the price will change before it becomes officially available.
Size & Weight
The Ranger Extender fits perfectly alongside the back of the Cybertruck’s bed. Instead of being laid evenly across the bottom of the bed, it’s nestled up against the cabin, making it easier to load items into the truck.
Elon Musk elaborated on the Range Extender's functionality: "It's an optional pack that fits in about 1/3 of the truck bed. There is still room for plenty of cargo. It's meant for very long trips or towing heavy things up mountains."
With a battery pack of 47 kWh, the Range Extender isn’t going to be something light. The Cybertruck’s “battery pack” is estimated to weigh about 600 to 650 lbs (272 kg to 294 kg), which also means that it’ll reduce the truck’s towing capacity by that much.
Installation
A few Cybertruck owners have discussed a marketing idea for the range extender would be to rent it out. Cybertruck owners could rent it for a weekend trip or an extended holiday camping. It's unlikely that Tesla will take on that business, but it is an idea for when more Cybertrucks are around and need that extra range.
Unfortunately, the Cybertruck Range extender is not something that could be easily removed or added, mostly due to its weight. Tesla has said that the Range Extender will need to be installed by Tesla Service and it’s a “permanent” install. We imagine it could also be removed at a later date, but it’s not something you could just do on your own when you don’t need it.
Unfortunately that means that owners will have to choose between additional range or cargo room. If you use the truck mostly for towing, the reduced cargo space may not be a big deal, but for other owners that use their truck for a variety of tasks, it could be a deal breaker.

Some Cybertruck owners have suggested renting the Range Extender for weekend trips or extended camping holidays.
However, the Cybertruck’s range extender isn’t designed for easy removal or installation, primarily due to its weight and high-voltage connections. Tesla has stated that installation must be performed by Tesla Service and is considered a “permanent” modification. While removal may be possible later, it won’t be something owners can easily swap in and out as needed.
This means Cybertruck owners will have to choose between additional range or cargo space. For those who use the truck primarily for towing, the reduced cargo capacity may not be a major issue, but for owners who use their truck for a variety of tasks, it may not be an easy decision.
Availability / Release Date
The Range Extender was initially expected to be available for pre-order customers in early 2025, but that timeline has now slipped to mid-2025. Given Tesla’s ambitious production goals this year, it wouldn’t be surprising if it gets pushed even further, possibly into 2026.
One potential reason for the delay is Tesla’s ongoing work on perfecting its dry-cathode battery process. Since the Range Extender is a low-volume product, Tesla may be prioritizing it as a testbed for dry-cathode cells before scaling them to full vehicle production. Unlike an entire truck, a battery pack like the Range Extender is easier to replace or refine if necessary.
In the meantime, Tesla is likely focused on the Cybercab and its next-generation vehicle. The Ranger Extender is expected to use the same 4680 battery cells as the Cybertruck, so Tesla will also want to ensure it has sufficient supply for vehicle production before producing the Range Extender.
