The 1942-1948 Pontiac Streamliner was the last prewar Pontiac and its postwar continuations in the division's upper-priced series. Fresh pontoon-fender styling was changed only in detail during these years. Top-line Chieftain models are the pick among the rare 1942’s; only 11,041 Eights and 2,458 Sixes were built.

Choicest of the choice would be the wood-body wagon and the slick sedan-coupe. The convertible was relegated to the Torpedo line. Postwar hallmarks were triple chrome fender strips and a full-width grille on 1946’s, a simpler grille for 1947’s, and a top-of-the-grille nameplate on 1948’s.

The last Streamliners appeared with "Silver Streak" chrome script, a term earlier applied to Pontiac styling. DeLuxe versions of the four-door sedan, wagon, and sedan-coupe were offered for 1948 only. The 1948’s were also the first Pontiacs to offer Hydra-Matic automatic transmission.
