Engine: The primary powerplant was a 7.0L (425 cubic inch) V8, which replaced the massive 500 cubic inch engine of previous years.
• Transmission: It featured the reliable Turbo Hydra-Matic 3-speed automatic transmission.
• Fuel Economy: While not "fuel-efficient" by modern standards, the weight reduction significantly improved its MPG compared to the mid-70s behemoths.
• Suspension: It utilized a coil-spring suspension designed for a "boulevard ride"—extremely soft, absorbing almost all road imperfections.
Notable Design Features
The 1977 model is often praised by collectors for its clean, crisp lines that defined Cadillac’s aesthetic for the next decade.
