I explained in detail a while back here https://www.pakwheels.com/forums/civic/244530-10th-generation-civic-exclusive-pakistan-launch-712#post5151058
see below pics; Car rear ended as posted by the owner and later pushed and wedged at rear end of a SUV stopped at front. Car experienced major front damage . As I mentioned various time in my blogs as well, to many it looks like weak point as far as the car react to slow speed front crashes but this is how the car safety is designed and most of the new cars will behave in same manner.
Drive Safe. Guys
The Civic X has new advancement with its frame. As far as number of air bags, and active safety features PKDM might be low in numbers feature wise but the main frame is same which contribute to the passive safety which is more important than active safety features.
The new car is based on an advanced compatibility engineering (ACE) body structure that has a new crash stroke design. The frame rails are created and fixed in a manner that they plunge downwards in a front head-on collision. In high-speed collisions, this technique will decrease the risk of engine thrusting into the passenger cabin.
The new frame is about 30kgs less than the prior generation but has 25% more torsional rigidity. High-strength steel is used in major crash zones while there will be a single piece sub-frame in the rear as well as delicate frame areas to absorb the collision force.
In US Civic is equipped with front passenger and driver airbags, side airbags with rollover sensors and also rear airbags as standard along with side impact beams. Honda has been declared TOP SAFETY PICK+ by Insurance Institute For Highway Safety? after conducting the crash tests. To pass for the 2016 TOP SAFETY PICK+, a car must earn good numbers in the minor overlap front, medium overlap front, side, roof strength, and head restraint tests, as well as an advanced or excellent rating for front crash prevention.
When we were talking about the visible weld quality on PKDM, its very important to understand that welds is altogether a complete engineering. Don't think of a guy sitting on the street with welding gun joining together the panels together. An improper weld makes a big difference because forces transfer from one panel to another via welds and weak welds can be disaster . Civic on design don't have a single frame door design means there is weld between panels. The quality of the weld is very important. Also PKDM Civic don't have side air bags. So occupants safety totally rely on the welds in joints on side impacts.
The rear end is designed with soft zones to fold in case the Civic is being rear ended. In actual unfortaunate scenario, if you see a more rear ended damage to Civic, please understand its deigned to behave like that. Its a safety feature not a design flaw. Same goes for front end, if Civic goes into front end collision, you might see a decent damages by have physical bent panels including pushed out fenders as well as hood folding up to make a way to engine to move away from passenger compartment, again its for safety of the occupants. yes you can see a major body damage in case of even low speed front end crashes. This is due to safety design. Its not a design flaw. This is the reason there is 5 star crash rating for Civic X in frontal crash.
