Fire, explosions, cars splitting in half, you name it. Wouldn't be fun to have your car explode in beamng? Or multiple car exploding? >
Explosions have been discussed to death. I'm no great fan of the search engine built into this site, but try to use it before posting. The consensus is that, since cars seldom if ever really explode in real life, and since this is a simulator, cars will not likely be capable of exploding. There's even some doubt that explosions could be aptly simulated. At the most extreme, fire may be implemented, though the community might find a way to mod explosions in someday. As for cars tearing in half, it was once possible, but when BeamNG made the switch from Cryengine-centric to modular (now using Torque), a few features had to be sacrificed. They plan on adding this back in, as far as I know. Just don't hold your breath.
