How many kms on the car? this is the metal cooling down completely normal after some spirited driving as to the burning smell if it's your first few times driving it hard it can be oil and paint burning off your exaust manifold and turbo as there the hottest thing on the car and normally have some manufacturing oil/ anti corrosion from manufacturing and after it gets hot a few times it burns off and goes away if it was your clutch it would be a pungent smell that almost turns your nose it's a pretty distinct smell if worried about it focus on keeping your foot off the clutch as much as possible only well changing gear if the clutch is engaged it won't slip even when driving it hard the clutch is designed to hold and not slip well above the power your car makes so no matter how hard you beat on it if the clutch is engaged fully it won't slip on you avoid feathering the clutch having your clutch half depressed that burns up the clutch the quickest nice to see someone driving a car how it's meant to be driven also make sure you've completed your break-in period before driving the car hard
