(Rollover Example)

Vehicle rollover accidents are among the most perilous in traffic incidents. Studies reveal that rollovers account for 35% of all traffic fatalities. For medium and large SUVs, their weight, high center of gravity, and large inertia significantly increase the risk of fatal rollovers, making them about 9 times more likely than ordinary sedans. Hence, the rollover prevention capabilities of these vehicles are crucial for ensuring driving safety.

How do we gauge an SUV's ability to prevent rollovers? The most authoritative test is the fishhook test, certified by NHTSA as an "accident-prone curve" and regarded as the "ultimate test field" for assessing a vehicle's rollover prevention. At 80km/h, 99% of vehicles roll over, making it a stern challenge. SUVs that pass smoothly demonstrate exceptional rollover prevention capabilities.

International Fishhook Test Standard: This test simulates high-speed obstacle avoidance and sharp turns to verify a vehicle's resistance to rollover. Vehicles must enter the test area at speeds ranging from 56km/h to 80km/h, swerve 270° to one side, and then quickly reverse the steering wheel by 540° within 2 seconds at maximum roll angle. The required steering speed of 720°/s is difficult even for experienced drivers, necessitating control by a steering robot to ensure objectivity.

(Denza N9 Successfully Challenges Fishhook Test at 160km/h)

For five years, the Porsche Cayenne held the record for the highest speed in the fishhook test among mass-produced SUVs at 82.4km/h. Denza N9, a large full-size SUV with a length of 5.25 meters, height of 2.03 meters, high center of gravity, and total mass exceeding 3 tons, faced greater challenges than the Porsche Cayenne. However, Denza N9 doubled the international standard speed, passing the fishhook test at 160km/h. During the test, Denza N9 remained stable, with all four wheels on the ground, meeting the passing standard of wheel ground clearance not exceeding 5.08cm. This extreme performance underscores Denza N9's ultimate handling stability and redefines safety standards for large SUVs.

(Denza N9 Sets New Benchmark for Safety)

Denza N9's achievement in the fishhook test at 160km/h is attributed to two core technologies. The CloudRide-A intelligent air suspension control system adjusts suspension damping and stiffness in real-time, optimizing support performance and effectively preventing rollovers. The i3T technology independently adjusts wheel torque during extreme steering, combined with the rear steering angle, to generate precise reverse yaw moments, maintaining vehicle stability. These technologies' intelligent coordination enabled Denza N9 to excel in the high-speed fishhook test, demonstrating its exceptional handling and safety.

From BYD Atto 3's industry-first high-speed tire blowout test to Denza Z9 GT topping the elk test with the highest score (93.6km/h), to Denza N9's full-scene "tire blowout show" on high-speed straight roads, curves, and snowy roads, and now Denza N9 setting the most extreme global record in the fishhook test (160km/h), BYD consistently uses technology to deliver the most reassuring driving experience and set new safety benchmarks!

On March 21, Denza N9 was officially launched. Beyond its unparalleled safety performance, it also comes standard with BYD's Heaven's Eye advanced intelligent driving system and boasts the largest third-row space in its class. This versatile SUV, safe, intelligent, and comfortable in every aspect, is poised to become a dark horse in the SUV market within the 500,000 yuan range.
