Chinese electric vehicle maker BYD is conducting a high-profile long-distance test to highlight its improved battery chemistry and superfast charging systems, sending a fleet of upgraded Z9GTs on a roughly 15,000 km journey from Rome to Hong Kong.
What BYD is demonstrating
The cars, produced under BYD’s premium Denza brand, are fitted with the company’s Blade Battery 2.0 packs arranged for greater energy density and resistance to overheating. BYD says the Z9GT can travel up to 1,036 km on a single charge, positioning it among the longest-range mass-produced pure electric vehicles.
Route and timing
The convoy began the trip on June 13 and has been traversing multiple European countries — including Italy, Croatia, Serbia and Turkey — as part of a roughly 43-day expedition that also passes through the Vatican and several Eurasian states before reaching Hong Kong around July 25.
Why this matters
On its face, the event is a technical showcase: range claims and charging performance are direct indicators of battery energy density and thermal management. For buyers and fleet operators, longer single-charge distances reduce range anxiety and can shift charging infrastructure needs toward fewer, higher-capacity stops.
- Battery: Blade Battery 2.0 configured to boost energy density and heat resistance.
- Range claim: up to 1,036 km per charge for the Z9GT.
- Expedition: ~15,000 km route over ~43 days from Rome to Hong Kong.
Commercial signals
The trip comes as BYD reports a sharp rise in overseas deliveries: in the first half of the year the company said overseas shipments rose 82.5% year over year to 471,091 units, making up 42.5% of total deliveries compared with about 20% the prior year. That shift underlines BYD’s push beyond China and suggests growing global demand for its battery- and charging-oriented performance claims.
| Metric | Figure |
|---|---|
| Planned trip distance | ~15,000 km |
| Claimed single-charge range | 1,036 km |
| Overseas deliveries (H1) | 471,091 units (up 82.5% YoY) |
| Share of total deliveries (H1) | 42.5% |
BYD links the timing to broader market shifts: it says the global energy disruption tied to the Israel–Iran confrontation has accelerated demand for battery-powered vehicles in some markets. The expedition also has symbolic overtones, invoking the travels of Marco Polo to frame the company’s push across continents.
Technically, the test highlights two trends: automakers increasingly prioritize energy density and thermal resilience to extend real-world range, and manufacturers are using public demonstrations to build trust around charging speed and battery longevity. For policymakers and infrastructure planners, a higher effective range could change where and how fast-charging hubs are deployed, while for competitors it sets a benchmark to match or exceed.
Whether the claimed range and charging performance translate into consistent, reproducible results in everyday conditions will be a key question for drivers and fleet buyers watching the remainder of the route and subsequent real-world testing.
