Question: The third generation Pontiac Firebird was introduced in late 1981 by Pontiac alongside its corporate cousin, the Chevrolet Camaro,  introduced by Chevrolet for what model year?
Context: Van Nuys Assembly was a General Motors automobile factory in Van Nuys, California.  The plant opened in 1947 producing Chevrolet Advance Design trucks.  Later it would produce several different models including Chevrolet full-size (Caprice, Impala, etc.), Chevrolet Corvair, Chevrolet Greenbrier, Chevrolet Chevelle, Chevrolet Nova/Buick Apollo/Oldsmobile Omega/Pontiac Ventura, and Chevrolet Camaro/Pontiac Firebird.  It also produced the Chevrolet Monte Carlo and the Buick Skylark.  The plant was closed in 1992 when Camaro/Firebird production moved to Sainte-Thérèse Assembly in Quebec due to air quality remediation efforts. The F platform, or F-body, was General Motors' small rear-wheel drive automobile platform from 1967 until 2002.  It was based partially on the GM X platform, which was used for compact applications instead of the sporting intent of the F-Body.  The only two vehicles to have been built using the F-Body platform are the Chevrolet Camaro and the Pontiac Firebird.  The fourth character in the Vehicle Identification Number for an F-body car is "F", on Fourth Generation vehicles.  Earlier Camaros and Firebirds had differing VIN codes, but are now commonly referred to as F-bodies. Boisbriand Assembly was a General Motors Canada automobile factory, which opened in 1966.  It was located in the Montreal suburb of Sainte-Thérèse, Quebec, now relocated to Boisbriand, Quebec.  It later was the site for production of the F-body Chevrolet Camaro and Pontiac Firebird.  The plant closed in 2002 and was demolished. The fourth-generation Chevrolet Camaro is an automobile which was produced by Chevrolet for the 1993 through 2002 model years; although the last 30 models were unofficially sold in 2003.  It was introduced on an updated F-body platform.  It would retain the same characteristic since the first-generation's introduction back in 1967; 2-doors, 2+2 seating, available as a coupe (with optional T-top roof) or convertible, rear-wheel drive, and a choice of pushrod V6 and V8 powerplants.  The 1998 model year was refreshed and revised with both exterior and engine changes.  The fourth-gen Camaro would last up through the 2002 model year when General Motors discontinued production due to slow sales, a deteriorated sports coupe market, and plant overcapacity. The Pontiac Firebird is an American automobile built by Pontiac from the 1967 to the 2002 model years.  Designed as a pony car to compete with the Ford Mustang, it was introduced 23 February 1967, the same model year as GM's Chevrolet division platform-sharing Camaro.  This also coincided with the release of the 1967 Mercury Cougar, Ford's upscale, platform-sharing version of the Mustang, The fifth-generation Chevrolet Camaro is a pony car produced by Chevrolet.  It is the fifth distinct generation of the Camaro to be produced since its original introduction in 1967.  Production of the new Camaro began on March 16, 2009 after several years on hiatus since the previous generation's production ended in 2002 and went on sale to the public in April 2009 for the 2010 model year. The Chevrolet Camaro is an American automobile manufactured by Chevrolet, classified as a pony car and some versions also as a muscle car.  It went on sale on September 29, 1966, for the 1967 model year and was designed as a competing model to the Ford Mustang.  The car shared its platform and major components with the Pontiac Firebird, also introduced for 1967. The sixth generation Chevrolet Camaro, produced by Chevrolet, was first revealed to the public on May 16, 2015.  Sales started in 2015 for the 2016 model year.  The sixth generation Camaro now utilizes the GM Alpha platform shared with the Cadillac ATS and CTS and features MacPherson struts in front, rather than the former Multi-link setup.  General Motors claims that 70 percent of architectural components in the new Camaro are unique to the car. The third generation Pontiac Firebird was introduced in late 1981 by Pontiac alongside its corporate cousin, the Chevrolet Camaro for the 1982 model year.  These were also the first Firebirds with factory fuel injection, four-speed automatic transmissions, five-speed manual transmissions, four-cylinder engines, 16-inch wheels, and hatchback bodies. The third-generation Chevrolet Camaro was introduced for the 1982 model year by Chevrolet.  It continued to use General Motors' F-body platform and produced a "20th Anniversary Commemorative Edition" for 1987 and "25th Anniversary Heritage Edition" for 1992.  These were also the first Camaros with factory fuel injection, four-speed automatic transmissions, five-speed manual transmissions, four-cylinder engines, 16-inch wheels, and hatchback bodies.  For 1987 a convertible Camaro was reintroduced, converted by ASC in relatively small numbers.  In 1989 Chevrolet introduced a IROC Z28 WS9 collectors edition in relative small numbers as well.  The third-generation Camaro continued through the 1992 model year.
