The electric grand tourer segment just gained a serious contender. The BYD Denza Z9 GT in its Ultimate trim arrives with a staggering 710 kW output and a claimed 0–100 km/h time of just 3.4 seconds.
Developed under BYD’s premium Denza brand, this flagship EV combines ultra-fast 800-volt charging, large battery options, and a technology-rich cabin. It’s designed not only to impress on paper, but to redefine what a luxury electric GT can deliver in daily use.
800-Volt Architecture Brings Faster Charging
High-Voltage Efficiency
The Z9 GT rides on an advanced 800V electrical platform. Compared with conventional 400V systems, this higher-voltage setup improves energy efficiency and reduces heat during high-speed charging.
That translates into shorter charging stops and more consistent performance during long-distance driving.
DC Fast Charging Capability
Official figures indicate DC fast charging rates of up to around 270 kW, depending on battery configuration. For drivers covering highway miles, that means meaningful range can be added in a relatively short time.
The system is engineered to support both high performance and everyday practicality.
Massive Battery Options and Claimed Long Range
The Denza Z9 GT is offered with battery packs starting at approximately 100–102 kWh, with larger versions reaching up to about 122.5 kWh.
Under the CLTC test cycle, range claims extend from 900 km to as much as 1,068 km. That equates to roughly 650 miles in ideal laboratory conditions.
Real-world range will vary depending on speed, temperature, terrain, and driving habits. Still, the large battery capacity positions the Z9 GT among the longest-range electric grand tourers currently available.
Tri-Motor Performance in the Ultimate Trim
710 kW Combined Output
The Ultimate version features a tri-motor setup that produces up to 710 kW, or approximately 952 horsepower. This level of output places it firmly in high-performance EV territory.
Power delivery is immediate, with strong acceleration at both city and highway speeds.
3.4-Second Acceleration
With all motors working together, the Z9 GT can sprint from 0 to 100 km/h in about 3.4 seconds. That’s comparable to many established performance EVs, while still maintaining grand touring comfort.
Multiple drive modes allow drivers to switch between relaxed cruising and more dynamic responses.
Luxury-Focused Cabin and Smart Cockpit
Step inside, and the Z9 GT emphasizes technology and refinement.
The dashboard integrates multiple large displays for the driver and front passenger. An augmented reality head-up display projects key driving information directly into the driver’s line of sight.
A high-performance smart-cockpit chip supports advanced connectivity, real-time navigation, and over-the-air software updates. The result is a digital environment built for seamless daily use.
Premium materials, supportive seating, and a spacious layout enhance comfort for long journeys. For families or professionals who travel frequently, the blend of performance and practicality is a key strength.
Design and Driving Experience
The exterior design reflects its grand touring mission. A low stance, aerodynamic lines, and sculpted body panels give the Z9 GT a sporty yet elegant presence.
Adaptive suspension is expected in higher trims, helping balance ride comfort with handling precision. On smooth highways, the focus is on quiet, stable cruising. In sportier modes, steering and throttle responses become sharper.
