1969 Chevelles were billed as "America's most popular mid-size car." They showed only minor changes for 1969, led by revised front-end styling. A single chrome bar connected quad headlights (which became a familiar Chevrolet trademark) with a revised front grille, now cast in ABS plastic, and a slotted bumper held the parking lights. Taillight lenses were larger and more vertical, flowing into the quarter panels. Smaller side marker lighting bezels were phased in (shared with the Camaro and using the lens assembly as the previous year). Front vent windows (hardtop and convertibles only) began to fade away now that Astro Ventilation (first introduced on the 1966 Buick Riviera which was used a year earlier on the Camaro and Caprice) was sending outside air into several Chevelle models. The Chevelle lineup slimmed down to Nomad, 300 Deluxe/Greenbrier, Malibu/Concours, and Concours Estate series, and the base 300 series was history. No longer a series of its own, the SS 396 turned into a $347.60 option package for any two-door model. That meant not just a convertible, sport coupe, or pickup, but even the pillared coupe and sport coupe in the lower-rent 300 Deluxe series (except the base 300 Deluxe El Camino pickup). Fewer SS396-optioned 300 Deluxe coupes and sport coupes were built than their Malibu counterparts and they are solid gold for collectors. The Super Sport option included a 325-horsepower 396-cubic-inch V8 beneath a double-domed hood, along with a black-out grille displaying an SS emblem and a black rear panel. More potent editions of the 396 engine also made the options list, developing 350 or 375 horsepower (280 kW). SS396s produced from this point on shared the same VIN prefix with the Malibu sport coupe (136), with the exception of the 300 Deluxe based SS396s using (134), where the original buildsheet and/or Protect-O-Plate (which is an aluminum tag included with the original sales invoice from Chevrolet dealers) can ID a genuine SS (especially for a numbers matching original which is unaltered); however, the VIN number alone cannot ID a genuine SS as in previous years. Around an estimated 323 Chevelle 2-door hardtops were fitted with an L72 427 cu in (7.0 L) rated at 425 bhp (431 PS; 317 kW) at 5,800 rpm and 460 lb⋅ft (624 N⋅m) at 4,000 rpm of torque, where some Chevrolet dealers used the Central Office Production Order (this also included some Camaros and Novas of the same model year) - some COPOs were sold through select Chevrolet dealerships and out of the 323 COPO orders, a confirmed 99 were sold through the Yenko Chevrolet dealership in Canonsburg, PA. During the 1969 model year a police package (RPO B07) was available on the Chevelle 300 Deluxe 4-door sedan where some were optioned with the RPO L35 (396) motor along with a boxed frame (also shared with fleet orders e.g. taxicabs and rental cars); at the time the police option was reintroduced since the 1964/65 model years (at the time midsize squads came with economy powertrain usually in the case of the Chevelle a third generation Chevrolet inline six. The 300 Deluxe squads was not a sales success since the market was dominated by rival manufacturer Chrysler Corporation where its B platform (and its full sized sedans) outsold its competitors. Chevelle station wagons came in three levels: Concours, Nomad, and Greenbrierthe last a badge formerly used on the Corvair van. A new dual-action tailgate operated either in the traditional manner or as a panel-type door. Wagons stretched 208 inches (5,300 mm) overall versus 197 inches (5,000 mm) for coupes. Also the Concours option package (ZK5, ZK6, and ZK7) from the previous year was continued. New round instrument pods replaced the former linear layout. Chevelle options included headlight washers, power windows and locks, and a rear defroster. Chevy's midsize production rose this year. About seven percent of all Malibus had a six-cylinder engine, while about 86,000 came with the SS 396 option. All 1969 Chevelles had a new locking steering column one year ahead of the Federal requirement, and headrests required for all cars sold in the U.S. after January 1, 1969.
