The Pontiac 2+2 is a full size automobile that was manufactured by Pontiac, built on the B-body chassis. It debuted for the 1964 model year as a trim-only option for the Pontiac Catalina, with special door panels, bucket seats with a center console, and exterior badging. Pontiac marketed the 2+2 as the "big brother" to the popular Pontiac GTO. Beginning in 1965 the name Catalina was no longer found on the car, although it was still an option on the Catalina. The 2+2 was equipped with a V8 engine, dual exhaust, heavy-duty front springs as well as unique exterior body trim. It continued on the same platform, but became a separate Pontiac series for the 1966 model year. The 2+2 reverted to an option on the Catalina for 1967 and was discontinued in the United States the same year due to poor sales. It continued as a series in Canada until 1970. All Canadian-built 2+2's were equipped with a Pontiac body on a Chevrolet chassis, with the full range of Chevrolet engines available from inline 6-cylinder to big-block V8. The name 2+2 reappeared briefly in 1986 on the Pontiac Grand Prix 2+2 G-body "aerobody" coupe, of which 1,225 were built. Design The designation 2+2 was borrowed from European sports car terminology, for a seating arrangement of two in front plus two in the rear. It was designated officially at Pontiac as a "regular performance" model, a thoroughly confusing designation for a vehicle that was clearly intended to be to the Catalina platform what the GTO was to the A-body Lemans: the standard drivetrain was a 2-barrel carburetor version of Pontiac's V8 coupled to a floor-mounted 3-speed manual transmission; 3-speed automatic and 4-speed manual were options, as were a 4-barrel and Pontiac's 3x2 Tri-Power configuration. The suspension was stiffened with heavy-duty springs and a sway bar for improved handling. Starting in 1965 the 389 was replaced by a high-compression V8, with displacement increased to the 428 CID in 1967. Although the 2+2 was discontinued by 1968, all options (except the Tri-Power, which Pontiac discontinued after 1966 under a mandate from GM) were still available, and units could be ordered with what amounted to a 2+2 without the badges. Exterior The 2+2 was only available as a hardtop coupe or convertible. Distinguishing a 2+2 visually from a Catalina were faux louvers on the fenders or quarter panels. Annual changes meant the look
