The F-16's max speed is far greater than Mach 1.2, I thought, or at least it used to be before they added on weight to the thing.
It's also well known that the designers optimized the F-16's ability to quickly lose/gain kinetic energy, what they call "dump and pump". This is hard to quantify.
Some of the "nextgen" fighter capabilities widely touted are "supercruising" (i.e. supersonic flight without afterburner) and thrust vectoring, i.e. changing directions quickly by nozzling engine thrust off center. Amusing, the original YF-16A prototype could supercruise, and execute a "buttonhook turn" maneuver, without the fancy 21st century engines.
Imagine what the F-22's P&W F119 engine could do in a modernized F-16 airframe....
