GCC specs are region-specific. Cars equipped with GCC specs will have air filters, radiators, and air conditioners suited to the GCC region. Think of these as customized cars designed to withstand the tough environmental conditions in the Gulf region.
For example, Dubai can get numerous sand storms throughout the year which easily exposes the car’s mechanical system to sand and dust. The air filters in GCC spec cars are modified to protect the engine and the radiators are designed to adapt to the extreme heat conditions.
