The crew compartment - or Orbiter - which was blown clear of the main SRB's and fuel-tanks made water impact at approximately 207mph. It took a little over 2 and a half minutes to fall from the peak of its ballistic arc, which was around 65,000ft. The actual impact force was something around 200g, and in the unlikely event that any of the crew were still concious they would have been instantly killed - the speed with which it hit the Atlantic literally tore it apart. It took six weeks to discover its eventual location, 100ft below the surface.

About as fast as a regular Dodge Challenger vs a "regular car"...
Depends on the engine and transmission
