Tesla Added 2,500 Supercharger Stalls in Q1 — and Quietly Ended the V3 Era
5 min read read
Tesla's Supercharger network keeps expanding while almost no one talks about it. Q1 2026 added 2,500 stalls globally, an increase of 19% year-over-year. The bigger story is structural: on March 16, 2026, Gigafactory New York produced its last V3 Supercharger cabinet.
The V3 cabinet had been Tesla's flagship charging hardware since 2019. Every new Supercharger going up now uses V4.
Why the V4 Transition Matters to Owners
| Spec | V3 Cabinet | V4 Cabinet |
|---|---|---|
| Peak power per stall | 250 kW | 500 kW |
| 800V vehicle support | No | Yes (native) |
| Cable length | Standard | Longer (fits other-brand ports) |
| Cabinet design | Fixed installation | Foldable for rapid deployment |
The 500 kW number is the headline. Today's Tesla vehicles top out around 250 kW peak charging, so V4 doesn't unlock new speeds for a current Model 3 or Y. But the Cybertruck, the next-gen Roadster, and any future Tesla running on an 800V architecture will charge meaningfully faster on V4 — and so will Lucid, Porsche Taycan, and Hyundai E-GMP vehicles using NACS adapters.
Non-Tesla Pricing Premium Is Real and Visible
Tesla charges non-Tesla EVs more per kWh at the same Supercharger. The price spread varies by site, but a frequently cited example is Taylorsville, Utah V4: $0.27–0.37/kWh for Tesla owners versus $0.38–0.52/kWh for non-Tesla owners — a roughly 40% premium.
The premium softens for non-Tesla drivers who buy Tesla's Supercharger Membership ($12.99/month), which closes most of the gap. But the default price difference exists by design: Tesla's network was built with Tesla customers' subsidies, and non-Tesla pricing helps recover the original capital cost.
Adoption: Almost Everyone Is on NACS Now
By early 2026, nearly every major automaker selling EVs in North America has either committed to NACS or shipped vehicles using adapters. Ford, Rivian, GM, Hyundai, Kia, Mercedes, Volvo, Polestar, and others have access tiers. The hold-outs are shrinking, and the holdout case ("we'll build our own network") looks worse every quarter.
"The Supercharger network is now also a bridge connecting Tesla to other automakers' customers and to a broader energy ecosystem."
What This Looks Like in 18 Months
If Tesla holds the 2,500-stalls-per-quarter run rate, the global network will pass 80,000 stalls by the end of 2027. That's roughly twice the next-largest dedicated EV charging network. Combined with the 500 kW V4 hardware, Tesla is positioning Supercharging as a standalone profit center — energy revenue, not just a customer-acquisition cost for the car business.
The Bottom Line for Owners
If you've been at the same Supercharger for two years and the cabinet still says 250 kW, your peak charging speed isn't getting an upgrade unless Tesla replaces the cabinet (which is happening at heavily-trafficked sites). For new builds, you'll see V4 cabinets and longer cables — better for driving in with low battery and finding any open stall, regardless of which side the port is on.
