Tesla Model 3 “Phantom Drain” compared to Model S and Model X

Published

on

Tesla Model 3 currently leads the pack in terms of having the highest parasitic battery drain, or better known as “Phantom Drain”, over Tesla’s more mature Model S and Model X.

Phantom Drain represents the amount of charge an electric vehicle loses when it is not being driven or operated by a person, similar to how smartphones lose battery power while in standby mode. In the case of Tesla vehicles, the battery discharges while the car is not being driven in order to provide power to its onboard electronics and auxiliary functions, such as the battery’s thermal management system. According to the Model 3 Owners Guide, the vehicle, on average, should discharge at a rate of around 1% per day, similar to Tesla’s quotes for the Model S and Model X’s battery drain levels.

However, looking at data collected through TezLab, a popular app among the Tesla owners community that tracks vehicle power usage, efficiency, and other statistics, Ben Sullins of the Teslanomics YouTube channel was able to see a significantly larger discharge rate from the Model 3. Ben was also able to compare the differences in vampire drain between the 3,855 Model S, 1,281 Model X, and 362 Model 3 being sampled.

Looking at the distribution of Phantom Drain between the Model S, Model 3 and Model X, it could be seen that around 60% of TezLab’s users experienced drain levels similar to Tesla’s quoted levels, which are on the 1-2% range per day. However, the differences between battery drain of the Model 3 and the Model S and X become more prominent over time. It’s worth noting that any parasitic losses as a result of TezLab connecting to the vehicle on a recurring basis may also be accounted for in the results being reported.

As noted by Ben, the Model 3’s Phantom Drain levels exhibited volatility sometime during the November 2017 to January 2018 period. Ben’s recent real-world range test using his RWD Long Range Model 3 on an LA to Las Vegas route showed an even more drastic level of Phantom Drain, with his car losing almost 20 miles of range while he and his companion ate lunch. That’s a loss of more than 6% from the Model 3’s rated 310-mile range in the span of an hour.

The drain levels of Model 3 owners using the TezLab app has started becoming more normalized, suggesting that the longer the vehicles are on the road, and as Tesla pushed firmware updates to its Model 3 fleet, the more consistent the cars’ drain levels became. Back in 2015, we covered a Model S that lost an average of 2.3% rated range per day while the vehicle was left in 16-degree Fahrenheit (-9 C) weather. 

Overall, Tezlab’s data shows that the Model 3 is becoming more consistent as the maturity of the vehicle’s software is improving. Other features like its battery thermal management systems and its auxiliary functions are improving over time as well. These improvements are a trademark of Tesla, which is known as one of the only carmakers whose vehicles get better after they roll off the showrooms.

Just days after unveiling the Xiaomi YU7, a vehicle that is considered as the Model Y’s strongest competitor yet, Xiaomi CEO Lei Jun gave a nod of respect to Tesla and its Full Self-Driving (FSD) program. 

In a post on Weibo, Lei Jun highlighted the remarkable nature of Tesla’s first autonomous delivery. He also acknowledged that Xiaomi still has much to learn in the electric vehicle industry.

Xiaomi CEO’s Nod of Respect

Lei Jun’s comments about Tesla’s FSD delivery were shared as a response to Tesla VP Grace Tao’s post about the recent feat. The Tesla VP shared several key aspects of the delivery, from the fact that there was no driver in the Model Y to the vehicle reaching over 70 mph as it drove to its owner. 

“For the first time in history, the vehicle was delivered to the owner by itself. There was no driver or remote control throughout the journey, and the maximum speed reached 115 kilometers per hour, and it arrived safely at the customer’s door. This is a brand new Model Y. Tesla always surpasses imagination with disruptive innovation. A new era, exciting!” Tao wrote in her post.

In his response, the Xiaomi CEO acknowledged Tesla’s incredible feat. “Tesla is indeed amazing, leading the industry trends in many areas, especially FSD. We still have to continue learning!” he wrote.

Xiaomi’s Recent Tesla Competitor

The Xiaomi CEO’s comments show that Tesla’s projects and leadership garner a lot of respect in the global electric vehicle sector. While Tesla and Elon Musk tend to be media punching bags in the United States and Europe, the company and its CEO seem to be taken very seriously in China. This was despite China being the world’s most competitive electric vehicle market.

Xiaomi itself has become one of Tesla’s strongest rivals in China, with its first car, the SU7, bringing the fight to the Tesla Model 3. Its most recent vehicle, the YU7, could very well be the Model Y’s most legitimate rival yet, as it is more affordable, bigger, and more feature-laden than Tesla’s best-selling crossover. The YU7 has garnered quite a lot of attention, with Xiaomi receiving 200,000 firm orders for the vehicle within the first three minutes of its launch.

Tesla silences FSD critics by posting full video of Model Y delivering itself to customer

When Elon Musk posted that the first Tesla had delivered itself to its owner, critics were quick to question his statement.

It is no secret that Tesla still has ardent critics today, many of whom remain convinced that the company and its leadership are lying about Full Self-Driving (FSD) and its capabilities. It was then no surprise that when Elon Musk announced that the first Tesla had successfully delivered itself to its owner, critics were quick to question the CEO’s statement.

Videos of the all-electric crossover’s solo drive to its owner soon silenced Tesla critics and their claims.

Tesla Posts FSD Video Proof—Twice

While Musk’s post on X about a Tesla delivering itself to a consumer was a notable update, his claims were not accompanied by any video. This was taken by some Tesla critics as a hint that the CEO’s claims were false, and that the feat probably did not happen. Musk, for his part, noted that Tesla would soon be posting a video of the self-driving car’s drive to its owner.

The electric vehicle community did not have to wait very long. Tesla later posted a video of its first autonomous vehicle delivery ever on X, much to the shock of social media users. As could be seen in the video, a Tesla Model Y was able to travel about 30 minutes on its own, from the end of Giga Texas’ production line to the home of its owner, several miles away. Tesla even posted the vehicle’s full 30-minute drive on its official X account later on. 

Critics Are Still Skeptical, But It’s Cope at this Point

Of course, Tesla skeptics remained unconvinced that the feat was legitimate, with some pointing out that the Model Y customer seems to have had an X account for years but never posted, at least until his car was delivered. Others also claimed that the whole setup seemed suspicious since the Model Y looked like it had manufacturer plates as it navigated Austin’s streets.

These concerns, however, do not seem like very strong arguments, especially at this point. Based on the evidence, it seems like Tesla really has figured out autonomous driving, and its cars are now able to operate safely on real-world roads on their own. Many have also become silent in their criticisms of Tesla’s FSD feat, especially after the company posted the full video of the Model Y’s autonomous drive. Overall, Tesla critics may remain doubtful about the company and Musk’s claims, but these concerns seem to have become forced at best.

Ford CEO Jim Farley shared some skepticism about Tesla’s camera-only approach to self-driving during a recent appearance at the Aspen Ideas Festival. When asked to compare Waymo and Tesla’s autonomous driving systems, Farley stated that Waymo’s LiDAR-based approach made “more sense,” citing safety, consumer trust, and the limitations of camera-based models.

Waymo’s LiDAR vs. Tesla’s Vision-Only Approach

Farley was speaking with author Walter Isaacson when he made his comments about Tesla and Waymo’s self-driving systems. As they were conversing about autonomous cars, Isaacson asked Farley which approach to self-driving he preferred.

“To us, Waymo,” Farley said, though he also stated that both Tesla and Waymo have “ made a lot of of progress” on self-driving, as noted in a Fortune report. He also confirmed that he has had conversations about the matter with Tesla CEO Elon Musk. Despite this, he said that Ford still considers LiDAR as a pivotal part of autonomous driving. 

“When you have a brand like Ford, when there’s a new technology, you have to be really careful. We really believe that LiDAR is mission critical… Where the camera will be completely blinded, the LiDAR system will see exactly what’s in front of you,” the Ford CEO stated. 

Tesla and Ford’s self-driving plans

Tesla recently launched a limited Robotaxi service in Austin, which uses autonomous cars with safety monitors in the front passenger seat. While controversial, Musk has maintained that Tesla’s vision-only approach will ultimately prove safer and more cost-effective in the long term. Tesla seems to be making headway towards this goal, with Musk stating recently that the first Model Y has been delivered autonomously to a customer in Austin.

Ford, for his part, is not pursuing its own fully autonomous, urban-driving system anymore. Instead, the company is focusing on “high-speed, eyes-off” experiences like BlueCruise. Ford does plan to partner with a company that has achieved true autonomous driving in the future, as soon as the technology is available.
