The Accord is equipped with anti-collision steel beams, with a rear thickness of 1.3cm and a front thickness of 1.5cm. Below is extended information about the Accord's anti-collision beams: 1. They are designed to reduce repair costs during low to medium-speed collisions and, to some extent, mitigate injuries to passengers. The door anti-collision beams, made of steel or aluminum structures, are installed inside the doors. Some are arranged vertically, while others are diagonal, extending from the bottom of the door frame to the lower edge of the window glass. 2. The door anti-collision beams are designed as an additional energy-absorbing protective layer to reduce the external forces that occupants might experience. It has been proven that door anti-collision beams provide significant protection when the vehicle impacts a stationary object.

I've been driving an Accord for almost five years and have seen its crash beam structure during repairs. The Accord has crash beams both front and rear. The front one is made of aluminum alloy, installed between the bumper and radiator, about three fingers wide, mainly used to absorb low-speed impacts. The rear one is steel, slightly thinner but positioned more outward. Last time my friend rear-ended a tricycle, it was the crash beam that took the impact, only requiring a bumper replacement. The new car design also includes energy-absorbing boxes at the beam edges, like two folded pieces of tin foil, which better disperse impact forces. The Accord's good performance in North American crash tests is largely related to this, but in serious accidents, the body frame strength is what really matters.

Having studied the structural design of numerous car models, the Accord's collision protection system is worth mentioning. This vehicle comes standard with front and rear crash beams. The front beam utilizes lightweight aluminum alloy with an "eye-shaped" cross-section design to enhance bending resistance. The rear crash beam varies by model year, with North American versions typically using high-strength steel around 2mm thick. During a teardown of an older model, I discovered the true brilliance lies in the energy-absorbing boxes connecting the beam to the frame rails - they compress like an accordion during collisions, elongating the energy transfer path. While the new-generation Accord's automatic emergency braking system proves more practical in daily use, those crash beams really save significant repair costs in parking lot fender benders.

Just bought a 10th-generation Accord Hybrid, and I specifically asked the salesperson about the anti-collision beams during pickup. The salesperson showed me the cross-section of the display car, confirming that both front and rear have metal anti-collision beams, with the front beam being more robust. The salesperson mentioned that all Honda cars now come standard with these, and the Accord's aluminum alloy front beam also helps reduce vehicle weight. The maintenance manual states that the anti-collision beams are mainly designed for collisions under 15 km/h to protect critical components like the radiator. Compared to my neighbor's Lexus, I was surprised to find that his rear anti-collision beam is actually thinner than my Accord's, which made me feel the purchase was worth it. However, I recommend that friends buying used cars should carefully inspect the beams for any signs of deformation or repair.

In our repair shop, we frequently encounter damaged Accords, and the front and rear bumper beams have been removed multiple times. The front bumper beam is typically made of approximately 3mm thick aluminum alloy, mounted onto the energy-absorbing boxes of the frame rails, and can be seen once the bumper is removed. The rear bumper beam is positioned further inward, and the one we worked on from a 2016 model was about 2.5mm thick. It's important to note that when replacing bumper beams, only genuine OEM parts should be used, as aftermarket steel parts have significantly lower tensile strength. We've seen cases where owners replaced the bumper beam with a used one without adjusting the positioning accuracy, leading to false radar alerts. Nowadays, the new Accord models feature eight radar sensors mounted on the front and rear bumper beams, meaning even a minor rear-end collision might require replacing the radar brackets as well.

As a family car buyer, safety features are my key consideration for choosing the Accord. The salesperson demonstrated the body structure on-site, with thick front and rear anti-collision beams as standard. The front beam adopts a hollow design to reduce weight without compromising strength, while also protecting pedestrians' legs. I was pleasantly surprised to find that the rear beam and trunk floor form an integrated structure, reducing the risk of cargo impacting the cabin during a rear-end collision. Compared to the Camry in the same class, the Accord's aluminum alloy beams are more expensive but offer superior energy absorption. During daily school drop-offs in traffic jams, rear-end collisions are my biggest concern, and this configuration provides much-needed peace of mind. Regular maintenance should include checking for beam corrosion, especially in coastal cities.
