The engine in my car was steaming and smoking the last time it was driven. There was also a strange smell.
The problem you describe is a blown leaking coolant hose or one of the cooling system components have started leaking. The strange smell may be the coolant burning off. This is a sweet smell. The cooling system has a leak and would need to be checked by a qualified mechanic to pressurize the system and locate the leak or reason for overheating.
