If you like to see cars getting smashed and explosions, then you will have a field trip with the videos from Destruction Nation. They are adding realistic models in their simulator and then try to see how these cars behave in collision situations.
Of course, it is not exactly as in real life, but the effect is good enough for games or even for action movies. As you can see i the video from above, sometimes the engine falls off, othertimes the car bursts in fire or simply gets ripped apart.
Have a good 10 minutes of fun.
