A bigger battery pack appears to be included in the refreshed model.
Last month, we reported on Tesla refreshing the 2021 Model 3. Despite prices remaining the same, the updated version of the brand's smallest sedan offering received a host of visual and performance upgrades, improved features, and, crucially, improved range. The dual-motor Model 3 Long Range model got the biggest boost of all, increasing its range by 31 miles for an EPA-confirmed 353-mile range. There was previously speculation as to what resulted in the increase, with theories bandied about including improved efficiency, heat pumps, and other ancillaries that all made the Model 3 better than ever. But an updated European registration document sourced by Electrek has confirmed the reason for the increase is a larger 82-kWh battery pack.
But how can there be registration documents when these vehicles haven't been delivered yet? Well, according to numerous forum users in Europe, European Tesla dealers issue the paperwork to customers well before the vehicles actually arrive, allowing buyers to register the vehicle beforehand, making the pick-up process a fuss-free affair. One Reddit user posted a picture of the registration information, confirming the newly increased battery capacity. Before the update, the Model 3 shipped with a 79-kWh pack in Long Range form.
For those who might think this is a sign of things to come from Tesla's new 4,680 cells announced at Tesla's Battery Day, it isn't. Instead, this correlates with previous reports from back in August, when Panasonic, Tesla's battery partner, confirmed it would be increasing its energy density by between 5 % and 10 % on all cells produced at the Nevada Gigafactory. The increase in battery capacity will result in more than just increased range, though, as Panasonic has subsequently confirmed that the cells for Gigafactory Nevada are also going to charge quicker than the previous battery packs. It stands to reason that this statement applies to all the 82-kWh battery packs.
