As of May 2026, the global electric vehicle market is witnessing a historic breakthrough: the 1,000 km range club. Chinese manufacturers have moved beyond “city commuters” to build long-range grand tourers that officially outperform most petrol and diesel cars in terms of distance per “tank.”
By leveraging solid-state battery tech and massive 150 kWh packs, brands like BYD and Xiaomi are effectively ending range anxiety. We have analyzed the leading long-range contenders, from the Denza Z9’s record-breaking efficiency to the Xiaomi SU7’s tech-first approach, to bring you the ultimate breakdown.
BYD Denza Z9 (Sedan & GT)
The Denza Z9 series is the first mass-production luxury lineup to consistently cross the 1,000 km threshold. The sedan version currently holds the record with a CLTC range of 1,068 km.
-
The Powerhouse: It uses BYD’s “Yi San Fang” tri-motor system, producing a staggering 1,140 hp.
-
Charging Tech: Despite the massive battery, it supports dual-gun fast charging, allowing a 10% to 80% top-up in under 15 minutes.
-
Aerodynamics: A sleek, low-drag silhouette helps maintain high-speed efficiency, which is usually the weakness of electric cars.
Yangwang U7 EV
Yangwang is BYD’s ultra-luxury division, and the U7 is designed to be the “S-Class of EVs.” It carries a massive 150 kWh Blade battery, one of the largest ever fitted to a passenger sedan.
-
Range: 1,006 km (CLTC).
-
Smart Features: It features a world-leading drag coefficient of 0.195 Cd and a quad-motor “e4” platform that allows the car to perform a “tank turn” or keep driving even if a tire blows out.
-
Performance: 0–100 km/h in just 2.9 seconds, rivaling dedicated supercars.
Xiaomi SU7 EV
Xiaomi has proven that a smartphone manufacturer can build a world-class car. The SU7 isn’t just about range; it’s about the “Human x Car x Home” ecosystem where your car and house devices talk to each other seamlessly.
-
Range: Up to 900 km (CLTC) in the Max/Ultra variants.
-
Design: A sporty, Porsche-inspired aesthetic that has made it a viral sensation.
-
Intelligence: Features Xiaomi Pilot, an AI-driven autonomous system that uses 508 TOPS of computing power to navigate complex city traffic.
Pros & Cons
| Pros | Cons |
| Zero Anxiety: 1,000 km range means you can drive across states without stopping. | Weight: These massive batteries make the cars extremely heavy, affecting tire wear. |
| Fast Charging: 900V architectures allow for adding 500+ km of range in 10-15 mins. | Price: Luxury long-range EVs remain expensive flagship products. |
| Performance: Instant torque and high horsepower figures (often 1,000+ hp). | Range Realism: CLTC figures are optimistic; real-world range is usually 25% lower. |
| Interior Tech: Massive OLED screens and AI-driven cabins. | Environmental Cost: Larger batteries require more raw materials (Lithium, Cobalt). |
Is Range Anxiety officially dead?
-
Yes, for the Premium Segment: With 1,000 km (CLTC) translating to a solid 750–800 km in real-world conditions, these cars can finally outlast a full tank of petrol. The Denza Z9 is currently the best “all-rounder” for those who want both luxury and distance.
-
Not Quite for the Mass Market: While these flagships are impressive, the technology is still trickling down. Most affordable EVs are still in the 400–500 km bracket.
