Hopefully this puts the "what batteries are in the Model S Plaid?" To an end. From MotorTrend, and yes, I would think they asked Tesla when they dropped of the Model S Plaid.
"When the now
popular Tesla Model S electric car was first introduced in 2012, there were no Superchargers available. Today, there are 25,000 Tesla Superchargers around the world, and with
the Model S Plaid adopting a new powertrain, Tesla was able to re-design the battery to take advantage of the third-gen 250-kW Supercharger.
Despite Tesla still using the 18650 form-factor cylindrical battery cells, these now have improved chemistry to deliver higher performance and durability. (This is the fourth major chemistry improvement since the first Model S.) With it newest 100-kWh battery pack, Tesla claims the Plaid can recover 187 miles of driving range in 15 minutes of charging at a V3 Supercharger. But just how realistic is that claim in practice? "
Tesla says its new Model S can charge faster and run longer, so we put it to a real-world test.
