According to UNECE Regulation No. 42, when struck at a speed of 4 km / h, the performance of lighting equipment and the tightness of engine systems, for example, cooling, must not be impaired. The car is beaten with three passengers, then, moving the pendulum at least 300 mm to the side, it is empty. And how does the bumper feel in this situation?

You must admit that in the age of tight parking and minor accidents, the ability to "keep punch" for the bumper is very relevant. We chose Lada Kalina as one of the most popular and modern domestic cars that need plastic bumpers not only as an element of decor. Which product has more stock? What should be preferred when searching for spare parts - a tuning product, a non-native spare part or a regular bumper?

WARNING TUNING

Honestly, the language does not dare to call this bespoke hack bumper. Oh, it’s not without reason that the seller, in spite of persuasion, did not name the true manufacturer: anti-advertising would be very helpful.

The bumper of Nizhny Novgorod "Technoplast" is distinguished not only by a moderate price - 2000 rubles, but also by good performance. Above is a honeycomb structure designed to absorb shock energy.

A piece of crooked, untidy plastic, completely covered with shells and scratches, is curved by a snake under its own weight. The corners are bristling with poorly crafted edges, the "sports" grids covering the slots seem to be borrowed from truck air filters. The cracks after installing the product are terrifying, but with it the feeling is growing that the editorial 4000 rubles have been spent for good reason. A negative result is also known to be useful.

He does not even try to resist. After the characteristic “banging!” A long crack runs through the bumper, several self-tapping screws and some small brackets get enough sleep. A fiasco, in which, in general, they did not doubt. It’s only a shame that, I repeat, according to the methodology, we have to hit each of the bumpers twice: with and without passengers in the cabin, shifting the impact location by at least 300 mm. The second attempt adds another crack and puts a bunch of “extra” parts on the floor.

At the time of the impact, it seems that the bumper from Nizhny Novgorod will now fly to pieces, because the speed of the pendulum is two times higher than planned.

PERSISTENT

Despite the absence of markings, the bumper, manufactured, according to the seller, at the Technoplast enterprise looks solidly. The price is also attractive: 2, 000 rubles - half the price of a failed tuning. Here is a flat surface, elastic and durable-looking plastic. In appearance, it may well compete even with its main competitor, a VAZ product.

"Native" bumper … overtaxed! "Native" bumper … overtaxed!

The bumper is a bit more naughty than I wanted, when installing, not wanting to fit into the side latches-latches. But effortlessly withstands the first blow, then the second, with an offset. Only slightly change the gaps between the body and the bumper and … right there, right before our eyes they are restored. Wow! But do not try to hit at 8 km / h - by American standards?

Such a blow is much more serious, therefore there is nobody in the cabin, the spectators are 10-15 meters in order to catch the Kalina rolling away by inertia in time. The loud crunch is obvious: this time the bumper could not stand the bullying. But apparently … everything is fine! Just removing the product, we find a pair of cracked brackets. In addition, the honeycomb structure is slightly damaged and, alas, the front shield is slightly deformed. They went too far, of course, but damage to the shield with an actually living energy-absorbing system looks strange: it would be better if it were the other way around. Nevertheless, the bumper withstood the European tests with flying colors.

SURPRISE Sneaked UNKNOWNLY

There was no doubt that the factory Togliatti (judging by the markings) product will withstand a certification impact. Thought to beat or not to hit the "American" 8 km / h? The machine itself, after two previous tests, is already causing an alarm: the sound signal does not show signs of life, and there has been a leak in the radiator. We will postpone the repair, but for now … Native bumper worth 3, 000 rubles. easily and naturally falls into place.

Alas, the “standard” 4 km / h was enough for the bumper. A vertical crack ran in a sullen wrinkle at the site of the impact. Something is wrong? We repeat the strike without passengers. All the same - a little more furrow appears on the side, an exact copy of the first. Recall: by standards, the bumper should not remain unscathed. Its task is to protect lighting equipment and the radiator. But the result is still unpleasant, because the previous product behaved much better.
