With respect to engine type, "NA" indicates "Naturally Aspirated" -- in other words, the engine doesn't rely on forced induction (supercharging, turbocharging or turbosupercharging -- regardless whether an intercooler and/or aftercooler is used).

In automotive applications, most gasoline (aka "petrol") engines are naturally aspirated; most diesel (aka "fuel oil") engines rely on forced induction.

Typically, gasoline-fueled engines using forced induction are marketed as high-performance vehicles.

NA stands for Naturally Aspriated, meaning no forced induction, as in a supercharger/turbocharger. There are at least 10 times more cars that are NA than super/turbocharged.

Pretty sure NA just refers to naturally aspirated, meaning not super-charged or turbo-charged. If I am correct then most cars are. Do you mean carburated? If so, not many new cars are anymore. Most are fuel-injected.

Googled NA and Wikipedia says same.
