BYD Linghui M9 (known internationally in various forms as the BYD Xia or eMax 9) represents the pinnacle of BYD’s DM-i 5.0 technology. By launching the Linghui sub-brand in early 2026, BYD is effectively "firewalling" its B2B operations.
The Linghui M9 is the physical manifestation of BYD’s "dual-track" ambition: dominating the high-volume commercial sector with Linghui while chasing Porsche-level prestige with its other sub-brands. M9 offers a staggering 1,163 km of combined range. It uses a 1.5L turbocharged engine as a generator, paired with the latest Blade Battery technology. This ensures that commercial operators never face downtime at a charger during a cross-city transfer.

The M9 is roughly 50% cheaper than the Denza D9, yet it retains nearly 90% of the visual presence.
Space Management: By using a slightly shorter wheelbase (3,045mm), BYD makes the M9 more maneuverable in dense city traffic—a critical "pro" for professional drivers—while still offering a cavernous 7-seat layout.
The Hardware Trade-off: The M9 skips the expensive air suspension (DiSus-A) and high-end hydraulic systems (DiSus-P) found in the Denza, opting for the DiSus-C system. This provides a comfortable ride for passengers without the high long-term maintenance costs associated with air bellows in high-mileage fleet use.
The Range Advantage: Interestingly, the M9’s focused 1.5T DM-i 5.0 system is tuned for absolute efficiency over raw performance, allowing it to edge out the heavier, more powerful Denza in total cruising range.
Expert Verdict: If you are a fleet operator or a high-mileage commuter who values "cost-per-kilometer" over "brand-per-interaction," the Linghui M9 is arguably the most rational vehicle BYD has ever built.
