Why do BYD cars all use twist-beam suspension?
2 Answers
Because the twist-beam suspension structure is simple and low-cost, while still providing acceptable handling. For general small and medium-sized vehicles, the twist-beam suspension has lower space and technical requirements compared to the complex spatial and technical demands of four-link or five-link suspensions. This is also an important reason why companies choose twist-beam suspension. Below is some relevant information about the BYD Qin Plus DM-i: 1. Fuel-efficient: The BYD Qin Plus DM-i is more fuel-efficient because it has plug-in hybrid functionality. 2. Quiet: The BYD Qin Plus DM-i achieves electric vehicle-level NVH, making it quieter. 3. Good power: The BYD Qin Plus DM-i has 2.0T-level 0-100km/h acceleration performance, delivering better power. 4. Dynamic styling: The BYD Qin Plus DM-i has a very dynamic appearance, and because it doesn't have a transmission, it possesses more reliable mechanical qualities.
Speaking of BYD's chopstick-style link design, it's primarily for cost control and lightweight considerations. I've studied many of their models before and found that this three-link structure can indeed ensure basic suspension functionality while significantly reducing production costs. Especially for models like the Qin PLUS, using high-strength stamped steel links reduces vehicle weight by over 20kg, which is crucial for EV range. Of course, it's somewhat thinner compared to five-link systems, but BYD compensates by thickening the ball joint bushings and applying special heat treatment processes. Owners who've driven the BYD Han all say they can't feel much difference in daily driving, though it feels slightly stiffer when going over continuous bumpy roads.
