The Vios is equipped with a rear anti-collision beam. The anti-collision steel beam is a U-shaped channel pressed from cold-rolled steel plates and connected to the frame longitudinal beam. As the first barrier of passive safety in automobiles, the anti-collision steel beam is an important safety device that absorbs and mitigates external impact forces, protecting the front and rear parts of the vehicle body. The Vios is a compact car with dimensions of 4435mm in length, 1700mm in width, and 1490mm in height, a wheelbase of 2550mm, and a curb weight of 1070kg. The front suspension of the Vios is a MacPherson independent suspension, and the rear suspension is a torsion beam non-independent suspension. It is powered by a 1.5L naturally aspirated engine with a maximum power of 81kW and a maximum torque of 138Nm, paired with a 5-speed manual transmission.

Having driven several Vios models from different years, I noticed that the older base versions often lacked a rear anti-collision beam, which was only added in crash tests or higher trim levels. Once, when my car was rear-ended, the mechanic pointed at the rear and said it was empty inside. Without this beam for cushioning, not only were the repair costs higher, but the vehicle damage was also more severe. I recommend checking behind the rear bumper liner yourself or clarifying the configuration before buying a car. If it's really missing, you can install an aftermarket product later, costing just a few hundred yuan. Always be extra cautious about the distance behind you while driving and avoid tailgating—safety comes first, and the absence of this beam increases the risk.

While servicing cars, I've encountered many Vios owners and noticed that the absence of a rear anti-collision beam is common in most base models. Mid-to-high trim levels might have it, but it's often not thick enough. This beam plays a significant role in dispersing impact forces during a rear-end collision to protect the vehicle's frame. If owners suspect their car lacks this component, a simple method is to lift the car and have a technician remove the rear bumper for inspection—no need for guesswork. If it's indeed missing, don't hesitate to invest in a new bumper with the beam assembly to enhance protection. Developing good habits like regular maintenance checks on wiring and using mirrors to gauge distance when parking can make a big difference.

I remember when I first bought my Vios, I didn't pay any attention to the rear anti-collision beam at all. It wasn't until a friend's rear-end accident repair bill showed the absence of this beam that I got a shock. Some models indeed don't come with it as standard, cutting costs by omitting it. New car owners should be more vigilant—don't just focus on the appearance and performance when buying a car; ask the seller more about the safety features. If it really isn't installed, you can compensate with driving skills, like reversing slowly and installing a radar for assistance. After driving for a few years, I've come to think that a Vios without a rear beam is still drivable; the key is to stay alert and not let your guard down.
