Denza Z9 GT: New EV Boasts 644-Mile Range & UK Launch Planned

BYD’s luxury brand, Denza, is making waves with the updated Z9 GT, claiming a range of up to 644 miles (1,036 km) on a single charge – positioning it as potentially the world’s longest-range electric vehicle. The refresh extends beyond range, with significant improvements to the plug-in hybrid variant as well, and plans are underway to bring both the Z9 saloon and the Z9 GT to the UK and Europe later this year.

The Denza brand has already found success in China, with its D9 MPV achieving 300,000 sales in under three years, according to Car News China. The Z9 GT builds on this momentum, leveraging technology from across the wider BYD group and focusing on a premium experience.

Understanding the Range: CLTC vs. Real-World Figures

Denza’s headline figure of 644 miles is based on the China Light-Duty Vehicle Test Cycle (CLTC). It’s crucial to understand that CLTC tends to be more optimistic than testing standards used in Europe (WLTP) or the United States (EPA). These different cycles account for varying driving conditions, speeds, and environmental factors. While a direct comparison isn’t possible without WLTP or EPA figures, the Z9 GT’s improvement – a 64% increase over the previous Z9 GT EV’s 391-mile (630 km) CLTC range – is substantial.

The updated Z9 GT will be available with two battery options: a 102 kWh pack offering up to 509 miles (820 km) of CLTC range, and a larger 122.5 kWh pack extending that to the claimed 644 miles. Interestingly, the standard Z9 sedan, utilizing the same battery packs, is listed with a potential CLTC range of up to 664 miles (1,068 km), potentially surpassing the Z9 GT. However, Denza has yet to officially confirm this figure.

Beyond Pure Electric: A Boost for the PHEV

The Z9 GT isn’t solely focused on battery-electric performance. The plug-in hybrid (PHEV) variant has also received a significant upgrade. A fresh 63.82 kWh battery pack now delivers an all-electric CLTC range exceeding 248 miles (400 km) – nearly double the 125 miles (201 km) offered by the previous model. This extended electric range blurs the lines between PHEV and full EV capability, offering drivers the flexibility of electric-only commutes with the reassurance of a gasoline engine for longer journeys. The PHEV powertrain combines a 2.0T engine with three electric motors, delivering a combined output of 858 hp (640 kW).

Performance and Dimensions

The Z9 GT maintains its sleek shooting brake silhouette, offering a blend of style, and practicality. Its dimensions are considerable – 197.6 inches (5,000 mm) long, 78.7 inches (1,990 mm) wide, and 58.3 inches (1,480 mm) high, with a wheelbase of 123.2 inches (3,125 mm). This places it in the same segment as the Porsche Panamera.

The Z9 GT will be offered in rear-wheel drive (RWD) and all-wheel drive (AWD) configurations. The RWD model boasts a 496 hp (370 kW) electric motor and a top speed of 155 mph (240 km/h). The AWD variant features a more potent setup with a combined output of 1,140 hp (850 kW) from a front motor of 308 hp (230 kW) and two rear motors of 416 hp (310 kW) each, achieving a top speed of 168 mph (270 km/h).

Fast Charging and Future Infrastructure

Denza is also exploring rapid charging solutions. The Z9 GT has been spotted utilizing BYD’s new flash-charging infrastructure in China, which features 1,500kW charging outlets capable of significantly reducing charging times. While the exact charging times haven’t been released, this technology promises to alleviate range anxiety and make long-distance EV travel more convenient.

What’s Next for Denza and Long-Range EVs?

The introduction of the Z9 GT and Z9 saloon to the UK and European markets will be a key test for Denza’s international ambitions. The success of these models will depend on how well their CLTC range translates to real-world driving conditions under WLTP testing.

Beyond Denza, the pursuit of extended range is a major trend in the EV industry. Mercedes-Benz, for example, has demonstrated solid-state battery technology capable of over 749 miles of range, as reported by TechRadar. The Volvo EX60 also claims over 500 miles of range on WLTP cycles. These developments suggest that 600+ mile ranges will become increasingly common in the coming years, potentially eliminating range anxiety for many drivers. However, it’s important to remember that range is just one factor; charging infrastructure, battery degradation, and overall vehicle efficiency will also play crucial roles in the widespread adoption of EVs.

The Z9 GT represents a significant step forward in EV range, and its arrival in Europe will be closely watched by both consumers and competitors. Whether it truly delivers on its 644-mile promise remains to be seen, but it undoubtedly raises the bar for electric vehicle performance.
