If you have no oil or any other leaks on your engine that are burning off when you drive hard then this the the cat in the exhaust system re-burning the unburned fuel that the engine did not. This will happen on all of today`s cars and is nothing to worry about. That is also why that when someone in front of you goes wide open or is also driving very hard with there car the person behind them will also smell this. Probably like the people behind you, lol. have it checked for leaks, if no leaks, All normal, no worry`s. Keep on driving it hard, more people should.

When a catalytic converter starts to fail it puts off a "rotten egg" smell. This can also sometimes be caused by a bad Oxygen sensor. Your car should not "smell bad" when being strongly accelerated -- there is definitely something wrong. Find a mechanic and get it on a computer, even if you do not have a "check engine" light, something is certainly close to failure.
Good luck.
