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
There’s been a spade of Cybertruck announcements that just came up all at once, so let’s see what the polygonal truck is up to in the month of November. We’ve got a variety of topics to cover, starting with some disappointing news about Tesla’s in-house wrapping services, which are being discontinued for the Cybertruck. But don’t worry — there’s plenty of good news to follow.
No More Tesla Wraps
Tesla no longer offers wraps for the Cybertruck as an option for US customers. Tesla began wrapping vehicles earlier this year but stopped offering wraps for the Cybertruck as of November 13th.
This comes after Tesla previously reduced the color options for Cybertruck wraps from seven to five. However, this isn’t too big of an issue—there are plenty of companies that specialize in vehicle wraps.
The reason Tesla stopped offering wrap services for the Cybertruck isn’t clear. Was there not enough demand? Did it take up too much time from technicians who are already stretched thin?
Given the long repair backlogs in the United States, it makes more sense to have service technicians focus on vehicle repairs rather than spending time wrapping cars.
Inventory Foundation Series
The Cybertruck Foundation Series is now available as an inventory vehicle in certain locations in the United States. That means you can pick up a Foundation-series truck with little to no delay.
Only a few trucks are currently in stock, but this will likely expand as Tesla continues to ramp production and begins to offer the non-Foundation Series trucks as inventory vehicles.
These inventory vehicles are only available in the United States. Canadian owners will still need to put down a deposit for a Foundation Series Cybertruck to get it soon.
Crossbars
Tesla has just announced it is offering a new set of crossbars for the Cybertruck. With a load rating of 200 lbs, it’s on par with roof racks for other trucks. These crossbars also come with mounting pads and quick releases. There are also slots for attaching ski racks, bike racks, or even cargo boxes, letting owners expand the truck's storage capacity.
Interestingly, the Foundation Series trucks can install the crossbars over the cabin or the truck bed, while the non-Foundation Series can only mount the crossbars over the truck bed. That isn’t the greatest news - because one of the best uses for these crossbars is protecting the cabin glass when you’ve got items like long wooden planks hanging over the roof of the truck. Maybe we’ll see more on this soon.

Not a Tesla App
Update: It turns out that you can, in fact, install the crossbars anywhere on a non-Foundation series vehicle. You’ll just have to pay for an additional roof applique, according to Wes Morril, Lead Engineer of the Cybertruck Program.
Faster Charging
Tesla announced updated versions of the V4 Supercharger, with a more powerful electrical cabinet that can charge the Cybertruck at up to 500kW. That’s an insanely fast speed—nearly 1,300 mi/hr of charging. This will come as part of a future update for the Cybertruck and as V4 Supercharger stations begin to be deployed.
That’ll make the Cybertruck the fastest-charging Tesla - even with its enormous battery.
Tesla has revealed its updated V4 Superchargers, which have a massive power increase and can charge vehicles at up to 500kW. The V4 Superchargers have been a work in progress. They were initially launched with a v3 cabinet, limiting their overall potential.
V3 and V4 Superchargers have been charging at 250kW for several years, but recently, Tesla started a public trial at some locations with Superchargers reaching power levels of 320kW. This speed bump out of the 250kW zone was our first indication that Tesla was looking to roll out improved charging speeds.
With these new V4 Supercharger cabinets, Tesla is ready to blow these numbers out of the water, however, not every car will be capable of charging at the new 500kW speeds. Fun fact: Tesla’s Superchargers first arrived with a charging speed of just 90kW.
V4 Supercharger Cabinet
The V4 Supercharger has been around for some time—it's the new one without a hole in the center. However, those were running with V3 or V3+ cabinets. Now, the V4 cabinet has arrived.
The V4 Supercharger cabinet knocks that 320kW V3+ right out of the park. It can put a massive 500kW into the Cybertruck—currently the only vehicle that can use that speed. And that 500kW works out to a blistering 1,300 mi/hr for the Cybertruck — nearly 2100 km/h of charge speed.
Part of these charging improvements come from the Cybertruck’s 800V system, so we can’t expect all these charging improvements to roll out to older vehicles. Instead, we can expect the upcoming Model Y Juniper Refresh to likely also arrive with an 800V system, with all the experience and knowledge Tesla has gained from the first year of the Cybertruck.
If the new Model Y achieves charging speeds comparable to the Cybertruck, it could deliver remarkably fast charging times. Being lighter and more efficient than the Cybertruck, the Model Y could achieve a significantly higher miles-per-hour charge rate at the same 500kW charging speed.
These new V4 chargers will support vehicles with 400-volt and up to 1,000-volt vehicle architectures, so people with non-Tesla EVs that support 1,000 volts will also see some drastic charging improvements.
In its brief video, Tesla also showed off the updated V4 Megacharger dedicated to the Tesla Semi. The new MCS system can pull up to 1.2 Megawatts, which is 1,200 KW of pure power via the MCS connector for the Tesla Semi and its massive battery pack.
This upgrade for the Semi is going to be big, making it a prime option for companies looking to do short—and medium-haul trucking—nearly 90% of the trucking in North America.
V4 Supercharger Rollout
The rollout of V4 Superchargers will start early next year, with the first sites already undergoing permitting. Most interestingly, Tesla’s new V4 cabinet has also reduced the complexity of the Superchargers even further.
The V4 cabinet powers 8 posts, which is 2x more than the V3 cabinet. A smaller footprint and less complexity mean faster installations, which means more V4 sites faster.
These new Superchargers have the potential to ease congestion and help eliminate the negative perceptions of slow EV charging.
