: When I'm driving at say 35 or 40 mph, then I decide to 'floor it', I notice that there is quite a bit of smoke coming out from the tailpipes, that my rear window gets all fogged up. Is this normal because of the sudden change in engine speed, or is there something wrong with the car?

I've seen white "smoke" a couple times, but the fact that my rear window fogged up lead me to believe it was hot water vapor being expelled from the exhaust.
Remember, the exhaust system on the coupe is relatively large, so it probably holds more condensation that the typical car. Even on a reasonably warm day, the hot air from the exhaust could quickly turn any condensed water into steam, which would rise and quickly re-condence on the rear window. If it were actual smoke, I don't think your window would fog up. And if the window DID fog up from actual smoke, i think you'd see dark stains on the window or bumper.
If it makes you feel better, get it checked anyway, but I'd dount there's anything wrong.
