looks like a good result, but i dont think thats the same crash as the one done with the QQ and landwind. i think the QQ and Landwind are both 60km/h and is a head on one. the crash with the lobo looks to be hit only on the drivers side. but hey for such a new company that looks pretty darn good.

An offset crash puts greater strain on the structure of a car than a full-width collision.

This 56km/h offset test is (looks like) a legislation specs test. If the car meets these requirements it's EU road legal.

The QQ and Landwind tests were done at 64km/h and are also offset. Those tests are EURO-NCAP spec. (the QQ did reasonably well, better than the chevy spark/daewoo matiz, but suffered from the lack of an airbag)

The extra 10km/h of the NCAP test makes quite a difference in crash energy, the Lobo wouldn't look so hot in one of those tests.
The 10km/h increase in speed results in 40% increase in crash energy!

Why do you ask, well the 'energy' of the crash is related to "speed squared":

0.5 * mass * speed squared...

So 20% extra speed = 40% extra energy.

lots of physics comming in here, hey oo4load are you talking about the kinetic energy= 0.5mvsquared? i dont think its that simple though, theres alot to do with the conservation of momentum and total mechanical energy, and lots of friction stuff when the car jumps back on its tires. if it was that simple cars would never fail crash test.

Of course it's not easy to design a crash proof car, but that 40% extra kinetic energy is a simple fact.
It simply illustrates that the 'small' difference in speed has a significantly reduced impact severity.

It looks like the safety of Chinese cars is improving rapidly though, more so than that of Chevrolet/Daewoo cars for sale in europe who haven't managed to improve the 1 star rating of the 1997 Daewoo Lanos by the 2006 Aveo
