The Bible has no word on whether there are still Egyptian chariot remains at the bottom of the Red Sea.  Some very interesting and sophisticated amateur archeology has surveyed the sea bottom at the proposed Nuweiba beach Red-sea crossing. (This area is on the gulf of Aqaba between the Sinai Peninsula, now controlled by Egypt, and Saudi Arabia on the opposite shore.) The investigations have brought back video showing coral-covered forms that reasonably could be interpreted as possible Egyptian chariot remains.  We await further confirmation by the professional archeological community. However, due to the current political climate, and the stakes involved, we do not anticipate such verification anytime soon.
