Vehicle mass: What effet does it have in an accident?

[NC_Lane]

Hey all,

Been seeing all these articles on how a lot of the new small safe cars are better to be in a crash than in say a 4wd and I have question...

so we say for example that a there is a collision between a small say 1Ton car and a 3Ton 4wd at say 100kmph does it mean that the force encountered is the same for both vehicles?

From what I can gather, wouldn't there be say 3 times more force applied to the car than the 4wd? I would expect the 3Ton 4wd to slow down to a stop in this collision and the car to end up going backwords..

Does this sound right/can someone clarify?

Cheers,
