By the late 1980s, Oldsmobile tried to differentiate itself from GM’s four other core brands (Chevrolet, Cadillac, Buick, and Pontiac) by promoting its technological advances, starting with the dual-overhead-cam 2.3-liter Quad 4 engine introduced for the 1988 Cutlass Calais. This 150-horsepower cast-iron block and aluminum head four-cylinder soon made its way into other GM products, but as it was designed by Oldsmobile, the brand decided to push it a whole lot further. What’s more, the Quad 4 was also supposed to evolve into a 5.0-liter V-8 called the Quad 8.

Killing Oldsmobile still stands as one of GMs most short-sighted mistakes in my mind.

70s & 80s Olds were hugely popular.

90s Olds were less common (but were they marketed/developed as much as say Saturn?), but examples outlasted peers by years. We still have the odd Intrigue kicking around here. Swiss-cheese rusted and refusing to die.
