BYD Sealion 7 — Owner’s Guide
Written and edited by Ethan Cole, Editor-in-Chief · ✓ Technically reviewed by Daniel Wei Chen — Senior Chinese Automotive Diagnostics & Repair Specialist, Sydney · 21 August 2026.
The electric SUV coupe — and the clearest test-cycle lesson in the family: the 2026 WLTP entries show the same hardware reading 27 km shorter and 23 Wh/km hungrier than the 2025 listings. The measuring stick changed; the car didn’t.

Figures from the Australian Government Green Vehicle Guide (21 August 2026); where entries mix NEDC and WLTP cycles we say so — never compare across cycles. Warranty: 6 years/150,000 km vehicle · 8 years/160,000 km battery (dealer-network published terms).
