A Porsche 911 has two doors.
The 911 is a two-door sports-car family, most commonly built as a coupé, convertible, Targa or Speedster. Its classic layout places the engine behind the rear axle and typically provides either two seats or a compact 2+2 arrangement. The small rear seats in many versions do not make the car a four-door vehicle; they are accessed through the same two side doors.
The model debuted in 1964 as Porsche’s successor to the 356 and has remained in continuous production through multiple generations. Despite major changes—including the move from air-cooled to water-cooled engines with the 996 generation—the core two-door format has stayed central to the 911 identity.
The main potential confusion comes from counting seating capacity rather than doors. A 2+2 911 can carry four people in principle, while some variants are strictly two-seaters, but both configurations still use two doors. The 911’s front luggage compartment and rear engine cover are also not passenger doors.
