The heat radiating from the rear of the car is very normal, even with moderate driving. It can take quite some time to cool down after "spirited" play. It is not clear what you call a "hot smell"... but it is possible for roadway debris to get lodged under the car near the engine/muffler and cause this. My daily driver somehow got a plastic bag stuck to the exhaust pipe and it always smells like a molding shop when I put it into the garage...
