Why is the "Belgian block road" test for the YU7 called that? What does it test?
The name "Belgian block road" comes from the cobblestone roads commonly found in Europe, where there are gaps and height differences between the stones. The wheels are continuously pushed up and dropped irregularly, generating high-frequency impacts, which specifically tests the chassis's vibration filtering capability. The Belgian block road simulates the worst daily road conditions—speed bumps, potholes, and unpaved roads. It tests the suspension's ability to filter continuous bumps as the vehicle passes through.
This test was conducted on the T13 comprehensive performance road in Yancheng, featuring 25 characteristic road surfaces and 4 S-curves. In addition to the Belgian block road, it also covers granite roads, long-wave jump roads, and S-shaped roads, comprehensively evaluating the chassis's performance across four dimensions: support, handling, safety, and durability. During the Belgian block road test, the YU7 Standard Edition and YU7 GT were set to Comfort mode and driven at a speed of around 60 km/h. The suspension's bump filtering effect was excellent, and both models were able to quickly dissipate road impacts.
The YU7 Standard Edition is equipped with the Xiaomi Jiaolong Chassis and continuous damping variable shock absorbers, balancing vibration filtering comfort with sporty driving. The YU7 GT features the Xiaomi Jiaolong Chassis Master Edition, equipped with a closed dual-chamber air suspension and dual-valve CDC® continuous damping variable shock absorbers, tuned by a European team. Comfort mode softly dissipates impacts, while Sport mode reduces body roll and sway. A good chassis isn't just about being as soft as possible; it's about being able to filter vibrations when needed and support the body when required.
