The roof featured twin targa tops made of carbon fiber that could be stowed behind the rear passenger seats. In addition, the rear window retracted into a compartment located behind the rear passenger seats. The Oldsmobile O4's doors have a manner of front conventional doors and rear small suicide doors.
The O4 was also noted for its "info ring" which replaced the traditional instrument cluster. The info ring was inspired by the Palm Pilot and similar devices.

The linked authority identifier is Q7085741. None of the 0 selected statements returned an explicit reference. The first chronological checks are 2001.
Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
