Came across the latest technical details on Owner Discussion: BYD CTB (Cell-to-Body) Technology Explained: 40,500 Nm/deg Torsional Stiffness & Lower Cabin Floor — Thoughts & Specs Breakdown and thought I'd start a thread so we can compare notes and see what fellow owners think:
1. Key Highlights & What Stood Out to Me
How does Cell-to-Body (CTB) integration in the BYD Seal and Sealion 7 improve both handling and interior space?
- Instead of placing a separate battery box underneath the chassis floorpan, the top cover of the Blade Battery pack acts as the structural cabin floor itself.
- Saves 15 mm of vertical cabin height (giving lower sports-sedan seating posture) and boosts torsional rigidity to 40,500 Nm/degree—matching supercars!

3. What Do Fellow BYD Owners Think?
How do you see this fitting into your garage or next EV upgrade over the next 12–24 months? Keen to hear real-world thoughts from Atto 3, Seal, Dolphin, Sealion, and Shark 6 owners!
