The Oldsmobile 4-4-2 was a muscle car produced by the Oldsmobile division of General Motors.
Introduced in 1964 model year as an option package, it became a model in its own right from 1968 to 1971, then reverted to an option through the mid-1970s, and at several times during the 1980s and 1990s.
The "4-4-2" name (pronounced "Four-four-two") derives from the original car's four-barrel carburetor, four-speed manual transmission, and dual exhausts.
It was originally written "4-4-2" (with badging showing vertical bars between the numbers), and remained hyphenated throughout Oldsmobile's use of the designation. As early as 1965, 4-4-2s were available with 3-speed automatic transmissions, but were still referred to and badged as "4-4-2"s. By 1968 badging was shortened to simply "442", but Oldsmobile brochures and internal documents continued to use the "4-4-2" model designation.
