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 impacts greater than 5MPH. 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 section of the rear bumper. 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 an 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.
