Editing Quad 4 engine (section)

==Reception==
Following the engine's release in 1988, Oldsmobile promoted the Quad&nbsp;4 name with cars like the [[Oldsmobile Aerotech]]. Although the engines in the Oldsmobile Aerotechs were purpose-built and turbocharged, they were meant to showcase the design's capability. At the 1988 [[Indianapolis 500]], the [[pace car]] was an Oldsmobile [[Cutlass Supreme#Fifth generation|Cutlass Supreme]] convertible powered by a [[Turbocharger|turbocharged]] production Quad&nbsp;4.

After positive reviews for the first few years of sales, the automotive press began to criticize the Quad&nbsp;4 for its NVH levels when compared to turbocharged four-cylinders, [[V6 engine|V6]]es, and occasionally [[V8 engine|V8]]s.

The design gained a minor following in [[hot rod]]ding circles due to its resemblance to a 1930s [[Offenhauser]] engine once the ribbed aluminum cover was removed, exposing the tall cam towers and deep valley between them holding the spark plugs.<ref name="hemmings-mar2012"/><ref name="srm-mar2007"/>
