The latter may be individual "bucket" seats, fold-downs, or a full-width "bucketed" bench seat, but always with less leg room than either the front or a standard 2-door car.
Other common characteristics for 2+2 cars include relatively little room for the rear passengers and a "streamlined" body with two doors.
Some vehicles (such as the TVR Cerbera and Toyota iQ) have been marketed as "3+1" due to their front passenger seat having more space for forward adjustment than the driver's, allowing for more leg room for one rear-seat passenger.
This is because the term 2+2 is most often used to distinguish cars with what typically amounts to "auxiliary" rear seating, at times enlarged from a 2-seat version of the same model to accommodate it, such as the Jaguar E-type fixed-head coupé 2+2.
Other similar examples of stretched 2-seaters include the Lotus Elan +2, Mazda RX-8, and Nissan 280ZX 2+2.
