The electric-supercar arms race has produced plenty of outrageous numbers, but the Denza Z still makes most specification sheets look restrained. Revealed in production form at the 2026 Goodwood Festival of Speed, BYD’s premium-brand flagship combines three electric motors, four seats and charging speeds closer to laboratory equipment than today’s public charging network.

The Z will reach the UK first, with orders opening in late summer and initial deliveries scheduled before the end of 2026. Wider European expansion is confirmed, although launch dates and prices for continental markets remain unannounced.

Three versions, one wild powertrain

Denza will offer the Z as a Coupé, a folding-roof Spider and a track-focused Racing model with more aggressive aerodynamics, coil springs and optional semi-slick tyres. A more extreme Special Edition, reportedly targeting more than 2,000 PS and a sub-1.7-second sprint to 100 km/h, is planned for later.

All three current versions use a 500 kW front motor and two 340 kW rear motors. Combined output is 1,180 kW, or 1,604 metric horsepower—roughly 1,582 bhp—with 1,240 Nm of torque.

The Coupé reaches 100 km/h in 2.25 seconds, while the Spider takes 2.3 seconds. With optional semi-slick tyres, the Racing model cuts that to 1.96 seconds. Top speed is 300 km/h for the Coupé and Spider, rising to around 350 km/h for the Racing.

Those figures belong in hypercar territory. The less romantic detail is weight: every version carries more than 2.2 tonnes. The real test, then, will not be another launch-control video, but whether Denza can make that mass feel precise and enjoyable on an actual road.

A four-seat supercar, technically

Wolfgang Egger’s design team has resisted turning the Z into a collection of vents. It is low, wide and dramatic, but cleaner than many recent performance EVs. Its 2,780 mm wheelbase creates room for a 2+2 cabin, although the rear seats appear better suited to children, luggage or particularly optimistic adults.

Inside, the Z behaves more like a grand tourer than a stripped-out track car. Equipment includes massaging front seats, soft-closing doors, an 8.88-inch driver display and a 12.8-inch infotainment screen with Google built in. Devialet supplies 12 speakers in the Coupé and Racing and ten in the Spider.

There is also a configurable synthetic engine sound linked to the driving modes. Purists may object, but silence is not automatically character. Hyundai has already shown with the Ioniq 5 N that artificial feedback can add theatre when it is designed properly.

The charging claim is the real headline

Every Z uses a 76 kWh second-generation Blade Battery with lithium-iron-phosphate chemistry. Official WLTP range is 410 km for the Coupé, 400 km for the Spider and 380 km for the Racing. Those figures are modest for an expensive GT, especially beside electric saloons capable of comfortably exceeding 500 km.

Denza’s answer is Flash Charging. On a compatible 1,500 kW charger, the company says the battery can move from 10% to 70% in five minutes and from 10% to 97% in nine. Even at -30°C, a 20%-to-97% refill is claimed to take 12 minutes.

That sounds transformative, but there is an obvious asterisk: the performance depends on access to BYD’s dedicated ultra-high-power infrastructure. The company plans to build hundreds of Flash Charging locations in the UK, yet until that network becomes widespread, owners will have a car capable of drinking through a fire hose while often being handed a garden tap.

Pricing designed to provoke Porsche

UK prices start at £142,900 for the Coupé, £159,900 for the Spider and £172,900 for the Racing. Affordable? No. Aggressive within this market? Absolutely.

A Porsche 911 Carrera 4 GTS currently starts at £145,900 in the UK, produces 541 PS and reaches 100 km/h in 3.0 seconds. The Denza appears absurdly generous by comparison, but nobody buys a 911 by dividing horsepower by price. Porsche also sells decades of engineering credibility, a mature dealer ecosystem, stronger residual confidence and a driving experience refined over generations.

Electric alternatives make the choice more interesting. The Porsche Taycan Turbo starts around £135,200, while the 1,034 PS Taycan Turbo GT costs about £189,200. Maserati’s GranTurismo Folgore begins near £129,605 and offers less power but considerably more badge familiarity. At the extreme end, Rimac’s 1,914 hp Nevera remains faster and more exotic, although it occupies a very different financial universe.

The Denza will not suit everyone. Its limited range may frustrate long-distance GT buyers, while its weight and digital-heavy character are unlikely to charm drivers seeking a light, analogue sports car.

Denza Z electric supercar – final thoughts

The Denza Z is not merely trying to beat one Porsche. It is testing whether advanced technology can accelerate the creation of a premium brand.

On specifications, Denza has already made its point. The Z offers more power than a Taycan Turbo GT, costs roughly the same as a well-optioned 911 GTS and promises charging that makes current rivals look slow—provided the charger exists. Yet premium cars are not spreadsheets with leather seats. Porsche and Maserati still trade on heritage, confidence and recognisable driving character.

That is why the Z matters even before independent road tests deliver a verdict. Chinese manufacturers are no longer entering Europe only with cheaper family EVs; they are using halo cars to challenge the continent’s strongest brands on performance, software and charging.

Denza does not need to replace the 911 to succeed. It only needs enough European buyers to decide that history is desirable, but no longer compulsory.
