I was on my lunch and I saw a lot of smoke. Turns out it was coming from the exhaust of this late model, last gen to be exact 550i. When it took off even more smoke came out of the exhaust. I found it weird because the car was pretty nice. It just had an embarrassing amount of smoke coming out of the back:

Could it be running too rich? Or does the V8 in this gen of 5 Series have problems to make it smoke like this?
