Tips for staying warm in your Tesla this winter without killing battery range

As we near the winter months and temperature begins to drop across various parts of the world, Tesla owners living within cold climates will inevitably resort to their vehicle’s onboard climate control settings and seat heaters to stay warm. But understanding how much power each component consumes could mean the difference between going that extra mile, especially when driving in snowy conditions could rob upwards of 25% in range, and being stuck at a Supercharger longer than need be.
We take a look at the most optimal way to stay warm in your Tesla this winter, thanks in large part to the help of YouTuber and Model S owner, KmanAuto. He takes us an inside look on the amount of power Tesla’s SubZero Weather Package, and its heating and air conditioning (HVAC) system, consumes.
First, it’s worth noting that Tesla’s SubZero Weather Package is an optional add-on that includes the addition of seat heaters throughout the cabin, heated wiper blades, heated washer nozzles, and a heated steering wheel which Tesla later added into the package.
Using a third-party app called Remote S, KmanAuto measures the amount of current draw and power consumed by each feature within Tesla’s Subzero package. He then undergoes a series of tests combining seat heaters with the HVAC heater at different fan speeds and notes power consumption with each combination. At one point, Kman turns on the heater to ‘HI’ (82F) – commonly used by owners when first entering a frigid car – and measures a staggering 16.8A, 6.4kW of power consumed, or 18+ miles of range lost per hour. Though running the heater at HI for an hour is an unlikely scenario, especially considering the fact that the cabin temperature quickly reached 108 degrees Fahrenheit (42C) within a short amount of time, Kman brings to light that quickly warming up a vehicle using the heater could have significant and detrimental effects on range.
Instead, it’s advised to use seat heaters as the primary source for warming oneself up, combined with a slow warming of the in-cabin air by setting it to room temperature.
Tesla Subzero Weather Package + HVAC Energy Consumption
Energy consumption has been broken down by feature. Total energy consumption can be added together based on the number of features that are enabled.
Assuming a consumption of 333Wh/mile, we can compute the approximate range loss at miles per hour (mph) as a result of having these heating features on.
- Baseline (vehicle at rest but powered up): 247 Wh = .74 mph
- Defroster (rear window & side mirror heaters): 285 Wh = .86 mph
- Steering Wheel Heater: 95 Wh = .29 mph
- Heated Wipers & Nozzles: 95Wh = .29 mph
- 1 Seat Heater: 57 Wh = .17 mph
- 2 Seat Heaters: 133 Wh = .40 mph
- 3 Seat Heaters: 171 Wh = .51 mph
- 4 Seat Heaters: 209 Wh = .63 mph
- 5 Seat Heaters: 247 Wh = .74 mph
- HVAC at ‘HI’ or 82F (28C): 6.4 kWh = ~18-20 mph
- HVAC at 74F (23C): 342 Wh = 1.03 mph

Tesla Model 3 pickup “Truckla” gets updates and a perfectly wholesome robot charger

Back in 2019, YouTuber Simone Giertz, the self-proclaimed “Queen of Sh*tty Robots,” created a one-off Tesla Model 3 build that took the automotive world by storm. Fondly dubbed as “Truckla,” Giertz noted that the vehicle was actually her dream car — as crazy as that may sound.
Now almost four years later, the YouTuber posted an update on Truckla. And just like every other big project that one probably started, Giertz stated that she actually stopped working on Truckla when the vehicle was about 80% complete. The car is driving though, but a lot of stuff was not really working very well.
Thus, for her Truckla update, Giertz shared how most of her Model 3 pickup truck conversion was essentially completed. Truckla got a lot of detailing done, she got a slight lift, and she now has a functional tailgate. One has to admit, Truckla’s tailgate is pretty darn cool.
The “Queen of Sh*tty Robots” also opted to give Truckla a friend in the form of an automatic robot charger. Unlike Tesla’s rather interesting snake charger from years past, Truckla’s charger would come in the form of a rover, thanks to her friends at robotics platform Viam. Giertz aptly named Truckla’s robot charger friend “Chargela,” which is an appropriate name for such an invention.
Also true to form for Giertz, Chargela’s first encounter with Truckla was just a tiny bit awkward. One could say that Chargela may have just been a little bit nervous on his first try without human hands helping him. Most importantly, the system did work, so Giertz would likely keep using Chargela for her Model 3 pickup.
Teslas are very tech-heavy vehicles, so projects like Giertz’s Truckla are always remarkable. The fact that the Model 3 works perfectly fine despite having a good chunk of it cut off and turned into a pickup truck bed is mighty impressive any way one looks at it. Overall, Truckla will always be one of the coolest Tesla DIY projects to date, so any updates about the vehicle are always appreciated.
Truckla’s nearly four-year update can be viewed below.

Tesla fan creating ‘CyberRoadster’ using Model 3 Performance parts in epic DIY build

A Tesla owner is taking his hobby and love for electric vehicles to new levels by creating what could only be described as one of the coolest EV-related DIY projects to date. The idea for the project is simple: what happens when you cross a supercar with the Cybertruck? You end up with a two-seater CyberRoadster.
Tesla owner David Andreyev, who goes by the username @Cyber_Hooligan_ on Twitter, has spent the last few months creating a Cybertruck-inspired version of the next-generation Roadster made from a salvaged Model 3 Performance. Starting with a Model 3 Performance is an inspired choice, considering that it is Tesla’s first vehicle that has a dedicated Track Mode.
A look at Andreyev’s YouTube channel, which can be accessed here, shows the meticulous build that the Tesla owner has implemented on the project car. What’s particularly cool about the CyberRoadster is the fact that it’s being built with parts that are also from other Tesla vehicles, like its front bumper that came from a new Model S. Recent videos suggest that the project car’s rear bumper will be from a new Model S as well.
The journey is long for Andreyev, so the completion of the CyberRoadster will likely take some more time. Despite this, seeing the Tesla owner’s DIY journey on such an epic build is more than satisfying. And considering that the CyberRoadster is evidently a labor of love from the Tesla owner, the final results would likely be extremely worth it.
There’s a lot of crazy Tesla modifications that have been done as of late. But some, as it is with a lot of things on the internet these days, have become more silly gimmicks than serious automotive projects. Fortunately, car enthusiasts like Andreyev, who just happen to also love electric vehicles, are taking it upon themselves to create one-of-a-kind EVs that would surely capture the attention of anyone on the road.
Check out the latest video in the CyberRoadster’s creation below.

Tesla owner ‘charges’ Model 3 with homemade solar panel trailer

A Tesla owner has demonstrated a rather novel way to charge his Model 3. In a recent video, Sean Callaghan of the ItsYeBoi YouTube channel opted to use a series of off-the-shelf solar panel sheets onto a towable trailer to create a mobile charging unit for his all-electric sedan.
Callaghan planned to use only the sun and the solar sheets purchased from e-commerce platform Wish to charge his Model 3. The solar panel sheets would collect energy from the sun and transfer it to a control panel. The control panels were connected to batteries that would hold the energy—the batteries connected to an inverter, which would then charge the Tesla Model 3.
The entire assembly would provide the Model 3 with about 800 watts of energy on a completely sunny day. However, Callaghan shot the video when weather was overcast, so the entire solar panel trailer build only managed to provide around 300 watts throughout the YouTube host’s test.
To put this into perspective, a 100 volt home wall outlet provides 1.4 kilowatts of power, or 1,400 watts. Therefore, the 300-watt solar panel assembly built by Callaghan was producing less than 25% of the energy of a typical wall outlet. This is pretty marginal compared to Tesla’s 250-kilowatt V3 Superchargers, which provides 250,000 watts, or about 833 times as much power as the makeshift solar panel build.
However, Callaghan’s goal was not to charge the vehicle quickly. He explained the idea came from a previous video where he used a $5,000 Wish-purchased wind turbine to charge his Model 3. He wanted to test the effectiveness and efficiency of the system, which was questionable due to the time it would take to charge the battery fully.
The Model 3 battery pack is 78 kWh, and with Callaghan’s 300-watt system charging his electric vehicle, it would take 260 hours to supply the Tesla’s battery to full capacity.
In the past, electric vehicle enthusiasts have asked Tesla CEO Elon Musk why the company’s vehicles do not contain solar glass roofing, which would charge the car while the owner is driving. Musk has explained that the efficiency of this idea is challenging and likely would not provide an ample amount of range.
When asked about the idea of putting solar panels on the top of Tesla’s vehicles in 2017, Musk responded that the idea was “Not that helpful, because the actual surface of the car is not that much, and cars are often inside. The least efficient place to put solar is on the car.” It also would not be cost-effective for Tesla because “the cost of the panels and electronics, R&D and assembly would never pay for itself in the life of the vehicle, compared to charging from the wall in your garage,” Quartz noted.
That being said, Tesla plans to implement solar panels onto the motorized tonneau of the upcoming Cybertruck. The idea was discussed on Twitter when Musk stated that the optional feature would add “15 miles per day, possibly more” when parked in the sunlight. Also, fold-out solar wings could help capture enough solar energy for 30 to 40 miles a day.
