The network has been steadily updated since its inception in the early 2010s. It now features "V3" chargers, and the company says V4 chargers are on the way, but in the meantime the reputation of the current Supercharger network may outperform its actual technical capabilities. As Lucid CEO Peter Rawlinson told us in a recent interview, Superchargers are "old-fashioned," with a lower voltage than the current industry standard. Rawlinson is a former Tesla engineer who worked directly with Elon Musk to launch the Tesla Model S in 2012. Tesla also seems a bit shaky on its own performance. This week, its PR team shared a social media post that showed a dramatic drop in charge times since 2017, but then revised the tweet to show a less significant decline. The first graph, posted late on Feb. 20, shows a trend line that starts above 40 minutes and ends above 30 minutes. Those 10 minutes of time saved would be much appreciated by drivers.

It starts around 35 minutes and ends around 30 minutes. That would mean just five minutes of improvement, or half of what it originally reported. Which one is it?

EV influencer Kyle Conner commented. "A 20% drop in 7 years is bad," adds another commenter. "Tesla vehicle charging is falling behind the competition in terms of speed and curve in a meaningful way," says another. "And outside North America in Europe and Asia waaaay behind. Tesla is obviously more reliable and prolific, but let’s get some real innovation around charging speed please." One notes that Tesla shared a similar graph with even better numbers in 2023 at its annual Investor Day, shown below. Here, the charge times show a big improvement with an even lower final number. The line drops 10 minutes, from 37.5 minutes in 2018 to 27.5 in 2023. Does this mean Tesla is backsliding over time? Recommended by Our Editors
