What is the strength of the front anti-collision beam of the Qin Plus DM-i?
3 Answers
The strength of the front anti-collision steel beam of the Qin Plus DM-i is 1180DP. Here is more information about the Qin Plus: 1. Power: The Qin PLUS 2021 DM-i 55KM Premium model is equipped with a 1.5L naturally aspirated engine, with a maximum horsepower of 110Ps, maximum power of 81kW, maximum torque of 135N·m, paired with an E-CVT continuously variable transmission, and also equipped with an electric motor with a maximum horsepower of 179Ps and maximum power of 132kW. 2. Body dimensions: The Qin PLUS 2021 DM-i 55KM Premium model has a body length of 4765(mm), width of 1837(mm), height of 1495(mm), and a wheelbase of 2718(mm). As a compact car, the body dimensions of this model are moderate.
I've been driving this car for a while now, and I must say the front crash beam feels exceptionally sturdy. According to BYD's official data, it's made of ultra-high-strength hot-formed steel with a tensile strength reaching around 1,500 MPa, which is quite high for a compact car. During minor scrapes on urban highways, it barely shows any deformation, which gives me great peace of mind. The crash beam not only protects occupants but also absorbs impact forces to prevent engine damage. The key structural steel undergoes hot-pressing treatment, making it several times harder than regular steel. However, specific strength values vary slightly by trim level—the base model might be a bit lower, while higher trims upgrade to 1,700 MPa, all referenced in crash test reports. I chose BYD primarily for safety, and in one actual collision, the front end sustained minimal damage while I walked away unharmed, proving the crash beam's reliability. I'd advise against modifying it recklessly—the factory design balances lightweight and strength, and tampering could compromise safety.
As someone who frequently works on car repairs, we've tested the strength of front crash beams many times. The BYD Qin PLUS DM-i uses hot-formed boron steel, with a nominal tensile strength between 1400 and 1600 MPa, far exceeding the 300 MPa level of ordinary steel. The structure is simple but effective—the core frame is composed of multiple ultra-high-strength steel plates welded together, about 2 mm thick, capable of absorbing 70% of the impact force during a collision. If it gets damaged and needs replacement, it's best to choose genuine parts, as their strength is certified. Otherwise, aftermarket crash beams may drop below 1000 MPa, compromising safety. I've also noticed that the anti-rust coating on the material is well done; even after years in the humid southern regions, there's no sign of corrosion, which is a relief. Regularly check for loose clips or brackets during maintenance, as any deformation could affect the overall strength value. During repairs, we always verify the specifications against the VIN first to avoid misjudgment.
