Rumors are swirling in the electric vehicle (EV) community about an exciting development on the horizon for Tesla’s Model 3. Reports from China suggest that Tesla is planning to upgrade the base battery of the Model 3 as part of its ambitious Project Highland. The upgrade is said to involve replacing the existing 60 kWh battery pack with a more advanced 66 kWh battery pack, potentially resulting in a 10% increase in the EV’s driving range. This speculation has sparked anticipation among Tesla enthusiasts and industry experts alike.

One key aspect of this battery upgrade is the reported collaboration between Tesla and Contemporary Amperex Technology Co. Limited (CATL). It is believed that Tesla will utilize CATL’s M3P lithium iron phosphate (LFP) battery packs for the Model 3 upgrade. This battery technology not only promises improved energy storage capabilities but also aligns with Tesla’s ongoing commitment to enhancing production efficiencies and reducing costs. By incorporating CATL’s LFP battery packs into the Model 3, Tesla can provide a significant boost in driving range while potentially lowering production costs.

The history of the Model 3’s battery upgrades is worth noting. In its early stages, the base variant of the Model 3, the Rear-Wheel Drive, featured a 55 kWh battery, which was later upgraded to 60 kWh. The rumored 66 kWh battery upgrade would add another 6 kWh, potentially extending the driving range by approximately 30 miles (50 km). This enhanced range would not only benefit Tesla owners but also attract more potential customers who prioritize longer trips and reduced charging frequency.

However, the benefits of this battery upgrade extend beyond the driving range. CATL’s M3P battery packs are expected to be more cost-effective, potentially resulting in a reduction in the Model 3’s production costs. This move could lead to more competitively priced Tesla vehicles, making them more accessible to a broader demographic of environmentally conscious drivers. A more affordable Model 3 with an extended driving range would undoubtedly appeal to a larger customer base, further solidifying Tesla’s position as a leader in the EV market.

The timing of this battery upgrade is crucial for Tesla. While the Model 3 has achieved remarkable sales figures. However, the anticipated changes under Project Highland, including the battery upgrade, could serve as a catalyst for revitalizing the Model 3’s popularity and maintaining Tesla’s dominance in the EV market. Tesla’s consistent strategy of upgrading batteries with every model redesign has been instrumental in establishing its competitive advantage. By continually pushing the boundaries of EV technology and introducing higher-capacity batteries, Tesla sets new standards for range and performance.


All eyes are undoubtedly on Tesla as it continues to drive the future of electric vehicles. The anticipated range boost, combined with other potential improvements under Project Highland, has the potential to reinforce Tesla’s market position and further elevate its reputation as a trailblazer in the EV industry. As Tesla pushes the boundaries of innovation, the upgraded Model 3 will likely garner significant attention and attract new customers eager to experience the future of sustainable transportation.
