The new Denza N8 has over 1,000-km range thanks to BYD’s 130 kWh battery

Only three years ago, if you wanted four figures of driving range, you had to drag an internal combustion engine along for the ride. When BYD launched the original Denza N8 back in 2023, the electric variant came with a respectable 108.8 kWh battery pack. Buyers who suffered from chronic distance anxiety had to go for the plug-in hybrid model to hit 640 miles of combined range.

But three years in the Chinese EV industry is a lifetime. The latest regulatory filings from China's Ministry of Industry and Information Technology (MIIT) reveal that automotive goalposts haven't shifted - they have been completely uprooted. The new revised battery-electric Denza N8 has cracked 623 miles on a full charge, delivering the kind of cross-country endurance that matches its hybrid predecessor outright.

The secret weapon behind this endurance run is a massive 130.15 kWh lithium iron phosphate (LFP) pack. That is a colossal slab of cells to squeeze into a passenger vehicle, and BYD continues to refine LFP - historically dismissed by Western automakers as the heavy, budget-friendly alternative to nickel chemistry - into genuine high-end hardware.

For drivers who don't need enough stored juice to illuminate a small village during a blackout, Denza has also homologated a smaller 105.792 kWh battery. Depending on your chosen powertrain and motor count, official CLTC driving ranges are as follows: 497 miles, 522 miles, 603 miles, and that headline-grabbing 623 miles. Even after factoring in real-world driving conditions, the energy density at play here pretty much guarantees long highway legs.

Packaging a battery of that physical magnitude needs a serious footprint, and Denza is giving buyers two sizes of the SUV to choose from. The standard N8 measures 202.8 inches from snout to tail, stretches 78.7 inches across the hips, and stands 71.7 inches tall on a 121.1 inches wheelbase.

If you want a fraction more trunk volume for family expeditions, the stretched Denza N8L extends total vehicle length to 204.7 inches while maintaining the identical 78.7 inches beam and 121.1 inches wheelbase. Due to a slight bump in body mass and aerodynamic drag, the 130.15 kWh battery in the N8L yields a still-monumental CLTC rating of 597 miles.

The standard N8 is a fraction larger than the Li Auto L8, which checks in at 200 inches long with a 118.3 inches wheelbase. It also stretches well past European contenders like the Volvo EX90 at 198.3 inches. The elongated N8L nudges right up against full-size luxury haulers like the NIO ES8 at 207.9 inches and the Li Auto L9 at 205.4 inches. Visually, BYD's design team opted for clean restraint over dramatic overhauls: the new model keeps the sleek family front end while sporting tidied-up, parallel slim taillights that frame the rear badge.

The sensible entry point is a rear-wheel-drive single-motor setup available with either 320 kW (429 hp) or 370 kW (497 hp) - plenty of muscle for however demanding scenarios. But if somehow you find that inadequate, Denza will happily sell you a triple-motor all-wheel-drive brute. This configuration deploys a 270 kW (362 hp) motor on the front axle and pairs it with two separate 310 kW (416 hp) motors powering each rear wheel. That adds up to a combined output of 890 kW - or 1,193 hp - instantly turning what should be a sensible, three-row luxury cruiser into a street rocket.

A decade ago, Denza was a sleepy 50:50 joint venture between BYD and Mercedes-Benz, making awkward compliance cars that wouldn't move off dealer lots. It all changed when BYD took majority control, changed the styling direction, and launched the successful D9 luxury MPV. With Mercedes taking back seat, Denza has become BYD's technological showcase - a brand where the group debuts its best drivetrains and flagship battery tech.

That shift is paying off - Denza crossed a major barrier in June by delivering over 20,000 vehicles in a single month. July followed closely with 19,196 deliveries - a modest month-on-month dip of 5.7% amid typical summer sales lulls, but an impressive year-on-year jump of 68.8%. Achieving nearly 70% growth in the premium luxury bracket suggests that buyers are responding to genuine substance over marketing tricks.

But all that horsepower madness isn't what makes the updated N8 so compelling - it is the elimination of the classic EV compromise. The prevailing wisdom insisted that large, heavy SUVs needed a petrol generator under the hood to handle true long-distance touring. 130 kWh of LFP chemistry in a full-size hauler that casually cruises past the 620 miles barrier puts pressure on traditional luxury rivals. And it renders the hybrid crutch obsolete.
