NIO ET5: Cheaper than hundreds of thousands, the front and rear anti-collision beams are still aluminum alloy!
For NIO's cheapest sedan, the ET5, everyone must be concerned about its internal workmanship and materials? Today we will take it apart and start with the anti-collision beam to find out.
envelope
Aluminum alloy front cover
Except for the front hood, which is made of aluminum alloy, the rest of the skin is stamped steel.
This car is in line with international practice, there is a high-voltage interlocking rescue line near the top of the tower, and the whole car can be cut off in case of an accident.
Front impact beam
Aluminum alloy
Removing the front bumper, there is a very thick aluminium front impact beam with a thickness of 4.49 mm and a width that covers 72.34% of the front of the car.
The ET7 aluminum alloy front impact beam is 5.82 mm thicker, which is a bit thicker than the ET5, and there are two more extensions on both sides for a wider range of protection.
There is black pedestrian protection foam between the front bumper and the impact beam.
The ACC radar is mounted on the anti-collision beam, and the fixed bracket is made of plastic, which is easy to break if a low-speed collision occurs, which plays a role in protecting the radar.
Millimeter-wave radars are installed on both sides of the fenders for side monitoring.
The radiator is equipped with an active air intake grille to better control the temperature of the system.
There is an aluminum alloy secondary impact beam below the main impact beam to prevent pedestrians from being involved.
The secondary anti-collision beam energy-absorbing box is also made of aluminum alloy, which is connected to the front subframe, which is much stronger than the secondary anti-collision beam of the ET7.
Extending from the A-pillar to the front of the car, the Shotgun has a wrap-around design that not only absorbs energy in 25% crash tests, but also in actual deflection crashes.
The front energy-absorbing box is also a stout aluminum alloy with a detachable structure with collapse folds.
Rear impact beam
Aluminum alloy
The rear impact beam is also made of aluminium alloy and has a thickness of 3.33 mm, which can cover 72.34% of the rear of the car.
The ET7 has an aluminum alloy rear impact beam with a thickness of 3.05 mm, and the structure is similar to that of the ET5.
The rear energy-absorbing box is also made of aluminum alloy, and the weld seam is regular and dense, with collapse folds.
The rear impact beam does not protrude from the trunk lid.
Crash test
The NIO ET5 was sold in the European market, participated in the E-NCAP crash test, and received a good score of 5 stars. Because NIO does not have a factory in Europe, and the models sold in Europe are all domestic exports, the reference value of the collision results is very high.
summary
There is no cost reduction and efficiency increase
The front and rear impact beams of this NIO ET5 are basically similar to those of the ET7, and the front and rear are made of aluminum alloy that should be expected of a luxury car, and the cost has not been reduced because it is the cheapest car in NIO. Aluminum alloy auxiliary anti-collision beam, active air intake grille... These have been preserved. In addition, the car has undergone crash tests at the European E-NCAP and achieved a good score of 5 stars. From the current point of view, although it is cheaper than ET7 by more than 100,000 yuan, it has not reduced costs and increased efficiency.
So what about the chassis of this car? Please stay tuned for the follow-up dismantling content. (The conclusion of the measurement data in this article and video is only responsible for the vehicle, and the measurement data is responsible for the published experimental method.) ）
