These curves are aggregated, owner-reported degradation data — not official manufacturer figures. Your own result above is the number that matters.

How to find these values on your BYD

Wh/mi or Wh/km

On the central rotating touchscreen, open "Vehicle" → "Trip Info" or "Energy". Average consumption in Wh/km or Wh/mi is shown in the trip data.

Estimated Range

Estimated range is displayed prominently on the instrument cluster (behind the steering wheel) and on the main screen dashboard widget.

Battery Percentage

Battery percentage is shown on the instrument cluster next to the range and on the main screen status bar.

About the BYD Seal

The BYD Seal is BYD's direct assault on the Tesla Model 3 — a sleek electric saloon that combines the Blade Battery's proven LFP chemistry with a more sophisticated driving experience than BYD's other models.

The 82.5 kWh battery delivers up to 354 miles WLTP, impressive for an LFP-based car. DC charging at up to 150 kW is a significant step up from the Dolphin and ATTO 3, taking 26 minutes for 10–80%. The AWD Excellence variant uses a dual-motor setup producing 523 bhp for a 3.8-second 0–62 mph sprint.

BYD developed a 'Cell-to-Body' technology for the Seal, integrating the battery into the vehicle structure for improved rigidity and handling. The interior is premium-feeling with a 15.6-inch rotating touchscreen. It's a genuine step up in driving dynamics from BYD's earlier offerings — more engaging, better composed, and with a tighter feel that European buyers expect.

What the press thinks

BYD's most accomplished EV yet. Reviewers praise the strong range, improved dynamics over other BYDs, and the appeal of LFP battery longevity at this price point. The infotainment learning curve, limited public brand awareness, and rear visibility are the noted downsides.
