Part 3/7:
Tesla may be preparing to upgrade the battery pack for the entry-level Model 3 and possibly the Model Y. The new battery pack, called the 6M or E1A, is expected to have a 4% capacity increase from the current 60 kWh pack, reaching 62.5 kWh.
This battery pack could initially be introduced on the 2025.5 Model 3 rear-wheel-drive variant, potentially launching as soon as mid-November in Europe. The WLTP range is expected to increase by about 4 miles, and the pack is expected to weigh 2.2 lbs less.
