Tesla’s in-house 4680 battery cells are underperforming in European Model Y vehicles. This performance draws scrutiny compared to cells from LG Energy Solution and Panasonic.
The 4680 packs reportedly reduce driving range by 52 kilometers. These cells feature lower energy density than LG’s alternatives.
Charging from 10% to 80% takes 40 to 45 minutes with 4680 batteries. LG batteries complete the same charge in 27 to 30 minutes.
These results highlight manufacturing challenges at scale. Experienced suppliers currently maintain a technological advantage.
