What explains the multiple improvements that Tesla has made to its vehicles over the past few months? We have already mentioned that the company can use more energy-tight cells. They would have dropped the Model 3 battery pack from about 75 kWh to 82 kWh. Yet many claim that the increase in the range is due to increased efficiency. According to the YouTube channel Tesla Killer, there’s nothing in the 2021 Tesla Model 3.
Tesla Killer performed the same tests with two vehicles: a refreshed 2021 Model 3 with 18-inch wheels and a 2019 Model 3 with the same specifications and tires. Both cars drove 67.1 km (41.7 miles) on the same route without any significant weather change and did not show car differences: both have 1120990 cars on their rear axle.
As the youtuber argues, the consumption curves were almost identical, and both spent 12 kWh of charge. If there had been an improvement in the efficiency of the updated Model 3, it would have spent less energy on the same task. Tesla Killer the car will save about 4 percent of the cost. Oddly enough, the new cells on the 82 kWh battery pack were a 3.8 percent increase in energy density compared to the previous one.
The youtuber has promised to publish a new video soon to explain what is happening. Tesla Killer revealed a while ago that Tesla follows the buffer strategy of other car manufacturers differently, as the video below shows.
After fully charging your Tesla, you will get the full range that the battery offers. In this case it was 489 km. If you drive with a Tesla energy consumption constant of 153 Wh / km – or 15.3 kWh / km – the car will emit less. When the battery is apparently empty, it still holds about 5 percent of the charge.
In other words, instead of shutting down part of the battery capacity, as the Volkswagen Group does with its electric cars, Tesla hides part of the capacity when people drive because they will not pay attention to the consumption constant.
This does not prevent the battery pack from being fully charged – the main purpose of the regular buffer strategy, aimed at preserving the main component of the EV, but it allows the driver to burn fat if he does not find anywhere to charge not.
Back to the efficiency situation, which Tesla Killer appears to be, is that the increase in the range is solely due to cell improvements. We’ll have to wait for the second video to confirm this. Until then, we’re sure people will try to prove Tesla Killertests were incorrect and that the company did increase efficiency. We grab popcorn to watch this discussion.
