Despite Elon Musk’s bold predictions, the Cybertruck is, officially, a flop. Tesla is deliberately opaque about its sales numbers on specific models, so you have to squint to get a sense of just how badly the company’s unique pickup truck is performing in the real world. But we definitely have some idea. Here’s what we know, based on Tesla’s deliveries (a proxy for sales) released this week: The EV maker delivered about 384,000 vehicles in total, world-wide, between April and June this year — a record 13.5% decline from a year earlier. Zoom in, and it gets uglier for Tesla. Tesla doesn’t break out sales of the Cybertruck, one of its premium models that Musk says was inspired by the dystopian movie “Blade Runner.” It discloses just two categories — the Model 3 and Y in one category and, in the second, “other models,” which is almost entirely the company’s legacy Model S sedan, the Model X SUV and the Cybertruck. The company said it delivered about 10,400 “other” models in the second quarter, which itself is a huge problem for Tesla. In the same quarter last year, Tesla sold more than 21,500 “other” models. It’s hard to think of another word for a 52% decline other than a collapse. How many of those “others” are Cybertrucks, and how many are the Model S or X? That’s not entirely clear. But let’s look at the first three months of this year. Tesla sold about 12,900 “other” models, of which 7,100 were Cybertrucks, according to registration data from S&P Global Mobility. So a bit more than half. It’d be safe to estimate, then, that Tesla likely sold something in the ballpark of 5,000-6,000 Cybertrucks in the second quarter if consumer trends held steady. It might even be getting marginally outsold by the F-150 Lightning and GM’s electric pickups, rivals whose sales are also falling but weren’t nearly as hyped as Musk’s brainchild. The company didn’t respond to a request for comment. But even in a hypothetical world where all of those 10,400 deliveries in the second quarter were Cybertrucks, Tesla would still be massively underperforming the expectations set by Musk, who told investors two years ago that he expected Tesla to be churning out 250,000 a year by 2025. We’re halfway through the year, and Tesla has barely hit a fraction of that. Cybertruck sales have faced a number of challenges: Its $80,000-$100,000 price tag.
