The fifth-generation Pontiac Catalina is a full-size sedan built for space, a quiet ride, and long trips. If you are looking at this generation, you are looking at a traditional American four-door rather than a compact daily runner.
A Pontiac Catalina engine in this generation is the 6.6-liter gasoline unit in the 6.6 AT sedan. That powertrain uses an automatic transmission and rear-wheel drive, giving an unhurried drivetrain for highway work. It is a selected example, not every version offered.
