The escape-system SuperDraco engines and the maneuvering thruster Draco engines share the same fuel source. To use the SuperDracos for escape use, it's possible the fuel system is "driven" in a different way, possibly pumped up to high pressure so they can immediately fire with high thrust. But they share the same fuel tanks.

I’m pretty sure the abort system on this capsule uses the same propellants as its control trusters and control trusters on the ISS.
*ping*
The Dracos have a perfect safety record, and, in general, hypergolics have decades of use in spaceflight. They are extremely stable when they are are in the tanks.
Fuel tank sizes, locations, and pressures may also make Dracos safer than Superdracos.
ChiCom sabotage.
So anytime our behemoth federal government touches anything, it automatically becomes a public concern, and must require transparency far greater than government ever provides? Sorry, no.
Good God, do you people ever look at context?!?!
Crewed Dragon Capsule visits hyper-expensive, human carrying International Space Station.
Soon after, during a ground test, for some yet unknown and/or unpublished reason, said capsule goes BOOM!, obliterating the entire capsule.
Crewed Dragon Capsule shares many systems with Cargo Dragon Capsule.
Cargo Dragon Capsule is about to revisit the hyper-expensive, human carrying International Space Station.
To not think some transparency and common-sense precaution is required in this situation is delusional.
Thanks fieldmarshaldj. Since they don't need the superdracos for propulsive landing any longer (NASA nixed that), they should consider slapping on a tower jet which is a proven way to safely abort. And I don't believe it ever had to be used. And it certainly didn't blow up for no apparent reason.
