Airwolf would defeat KITT
Remember in Star trek 2: The Wrath of Khan when Dr. Mccoy points out despite Khan's superior genes and brainpower and everything, all his military strategy is 2-dimensional.
KITT, being only a ground vehicle, is stuck witht he same limitations. he can only calculate combat strategies along the X,Y axis.
Airwolf, on the other hand, is an air-to-ground combat vehicle able to fight in the X, Y, and Z axis.
This gives Airwolf more maneuverability and speed. Able to duck & dodge, bob & weave to miss any assault from KITT. the car, however, can only go left, right, forward and reverse to avoid a 180-degree assault from from the air.
Besides, Airwolf (which is piloted by a human being) has much more firepower than KITT, which can pilot itself but was programmed NOT to take a human life.
The only known "weapon" on KITT is a cutting laser and perhaps the micro-jammer (which is basically an EMP -- electro magentic pulse. Suffice it to say that Airwolf is sheilded against EMPs, being that it is state-of-the-art technology more advanced than anything else anyone has. Hence, why the CIA hasn't been able to find her on its own)
As for KITT's molecular bonded shell, that has proven defensible against standard weapons and fire, but it has only been tested against military weapons such as distant (repeat, DISTANT) cannon fire and machine gun fire.
A close-order sustained bombardment of Stinger missiles, Hellfire missiles, nuclear-tipped Falcon missiles and 40mm Vulcan mini-guns could at the very least disable the car, rendering it useless.
KITT did go through an armored car course underfire once and an army missile range and did successfully defend against military hardware in both situations, they actually said that they were useing military hardware during the demo of the limo that was being tested at the same time KITT went through the course, and he was able to withstand close encounters with mines throughout the course of the show.
