1978 Camaro Spotters Guide & New Features
After 4 years of the extruded aluminum bumpers, an all-new body color urethane front & rear fascia was finally added to the car. Intended to debut in 1976, production delays held up the restyle until this year. Now hidden behind the sleek new nose was the impact absorbing crash structure able to withstand greater than 5MPH impacts. The rear tail lights were redesigned as well, now incorporating 3-color lenses on either side of the fuel door in the center. The license plate was relocated to a molded in section of the rear bumper.
The Camaro wasn’t just continuing to blow the competition away on the street, but it pasted the rival Mustang in the showroom again, outselling the Ford 247,437 to 179,039. There was no competition.
Removable smoke glass T-tops (CC1) were now available. The Type LT and Rally Sport were back, with the RS a separate model as opposed to a RPO. Z28 sales were going up, up & away… The only things slowing down were the cars themselves with the higher gear ratios (except in the Z28). This was in the effort to improve fuel economy. Other things that were improved in 1978 included….

  • Rally Sport offered as a Camaro Model, not RPO.
  • 305 gets a 4 speed manual as standard
  • non-corroding nylon brake pressure switch replaces steel switch
  • lower control arm bracing to improve chassis stiffness.
  • redesigned rear spring shackles improve stability
  • brake line charcoal filter
  • Z28 gets decorative hood scoop and functional fender vents
  • Manual transmissions not available in California.
  • Fenders redesigned to mate with new fascia
  • Removable glass tops (CC1) debut
  • New color-Keyed Aluminum Wheels (YJ8)
