The GS or Gran Sport originally denoted a high-performance optional package available across many vehicles from Buick. Eventually the Buick GS became a standalone model and this later 1972 example features the 455-cubic-inch engine rated at 255 hp. This particular model is located in Dubai United Arab Emirates as part of a Vintage Car Collection.
The Buick GS 455 was the luxury performance car of the muscle car era from the early 1970’s, noted for its industry-leading high-torque power plant. The 455 ‘Big Block’ engine originally produced 350 hp on its introduction in 1970 and a ‘Stage 1’ upgrade to 360 hp was also an available option. New laws on emissions controls in 1971 saw compression, and with it engine power, reduced that year, before being reduced even further for 1972 models.
The major appeal of the GS 455 was as a Gentleman’s Hot Rod, more likely to be equipped with numerous comfort features and power options than the competitors of the day.
