Chevrolet Camaro Z28
The Z28 was re-introduced to the buying public in the spring of 1977 as a 1977½ in response to dramatically increasing sales of Pontiac's Trans Am, which sold over 46,000 units in 1976 and accounted for half of all Firebird sales that year. Like the Trans Am, the revived Camaro Z28 was an instant hit and was powered by a 350 cubic-inch V8 with four-barrel carburetor and 185 horsepower (175 horses with California emissions equipment), with most cars sold equipped with air conditioning and an automatic transmission for a comfort-oriented public. The cars were also available with a Borg-Warner Super T-10 4-speed manual transmission and minimal option packaging for those buyers interested in a performance-oriented vehicle. The half-year model was one of the few American performance vehicles available at the time. The car was capable of turning in quarter-mile times comparable to many of the 1960s muscle cars, and the chassis was developed to reward the driver with a first-class grand touring experience, capable of outstanding handling, especially in the hands of a competent high-performance driver.
More than one Z28 was sold as a stripped performance car, and in this trim the Z28 could outperform Pontiac Trans Ams and Corvettes on highways and canyon roads.
In other developments, intermittent wipers were offered as a new option and the 250-6 became the standard engine for both the sport coupe and luxury LT models. The 145-horsepower 305 continued as the base V8 and the four-barrel 350 optional on sport coupe and LT models was uprated to 170 horsepower (130 kW). However, due to a controversial engine sharing program whereby 350CID Chevrolet engines found their way into Oldsmobile models, this particular engine was in short supply. In fact, for a significant period of time the only way a potential Camaro owner could purchase it was to either order a 4-speed manual transmission or upgrade to the Z28 model. This year the optional "Bumperettes" were offered for the LT models (front bumper only) and were mandatory for all Camaro models sold in the state of California.
Output set a record for the second-generation Camaro, with 218,853 coupes produced. And, Camaro outsold Ford's Mustang for the first time ever.
