Downsizing arrived in a big way at GM in 1977. In light of fuel prices, foreign competition that was smaller and more efficient, and a consumer base that was trending away from land yachts, GM downsized its full-size cars. Underneath, there was a notable mechanical change for 1977: the engine.
The Eldorado was Cadillac’s last model to downsize, after the rest of the brand bowed to the interests of fuel economy and cleaner styling in 1977. There was of course another big downsizing coming in just a few years, but nobody was focused on that yet. The engine was also smaller, as the big block era faded from view.
