The new tech powering the EU Model Y are Blade Batteries, which offer a structural battery system for chassis design. The BYD cell-to-body (CTB) cells offer a reduction in weight as used in the BYD Seal model produced in China. But it seems at this point, it may be a hybrid of Tesla structure and BYD cells since no other changes to the Model Y have been revealed. However, the Model Y has lost some weight using the BYD battery tech.
The Model Y destined for the EU weighs in at 4,601 pounds (2,087 kg), which is a 145 pound (66 kg) reduction over the previous Tesla Model Y using 60-kWh battery tech. The base Model Y will be produced at the Tesla Gigafactory Berlin-Brandenburg plant and will be the only BYD-powered version on the line. Since the BYD tech is focused on the base Model Y, the Long Range AWD and Performance versions will still run the LG Energy 2170 cylindrical-type battery cells. But the next-gen 4680 battery tech is on the horizon and should be a game-changer for Tesla.
