the base Sport Coupe, Type LT, Z28, and the return of the Rally Sport. The Rally Sport (not badged RS as in previous years) featured a standard two-tone paint treatment. The Z28 models included a stripe package that was not deletable and featured the LM1 a V8 with a four-barrel Quadrajet carburetor that produced and of torque coupled to either a 4-speed manual or a TH-350 3-speed automatic. Another first for 1978 was T-Tops, although they were a regular production option on the 1977 Pontiac Firebird and were introduced on the 1976 Pontiac Trans Am 10th Anniversary Limited Edition. 1979 The biggest changes for 1979 were the introduction of the luxury-oriented Berlinetta model, replacing the Type LT, and a restyled instrument panel with a much flatter appearance than the previous wraparound design (although the gauges themselves remained in the same places as before). The base models, RS and Z28 remained, the Z28s now came with a front spoiler and fender flares much like its Pontiac Trans Am twin had, and now came with "Z28" decals that ran from the beginning of the front flares to the bottoms of the doors. Electric rear window defroster became optional this year, replacing the old blower type. Sales for 1979 were the highest ever for any generation Camaro before or since, numbering 282,571 units. Engine choices remained with the 250 I6 standard in the base and RS models, with the 305 2bbl being an option and standard on the Berlinetta. 1980 For 1980 the aged inline-six was replaced with a V6 engine, in California, a first for Camaro. The (4.4 L) 267 cu in V8 engine became an option on the base, RS and Berlinetta models this year. The Z28 hood included a rear-pointing raised scoop (air induction) with a solenoid operated flap which opened at full throttle, allowing the engine to breathe cooler air. A federally mandated speedometer also debuted this year, down from 130. Z28s had new optional grey 5-spoke rims (later used on the 1986–1988 Chevrolet Monte Carlo SS), a unique upper and lower front grill and smaller revised graphics on its doors. The side scoops were also changed from a louvered design to a flatter one with a single opening. The V8 was now only available on the Z28 this year. 1981 The 1981 model was nearly unchanged from 1980 and would be the last model year for the second-generation
