Buick GSX 2 Door Hardtop (1970)

The Buick Gran Sport name was first introduced on the 1965 Skylark as a competitor to the Pontiac GTO. The first Gran Sport had a Wildcat 325 horsepower 401 cid “nailhead” V8 and was known as a “gentleman’s Hot Rod”.

At the of the muscle car wars, torque was king and no competitor could dethrone the 510 lb.-ft. (678 Nm) of twist generated by the GSX’s available 455 Stage I V-8 engine. In a 1970 road test, Motor Trend went from 0 to 60 mph in 5.5 seconds and covered the quarter-mile in 13.4 seconds. The GSX’s combination of raw power and Buick’s signature luxury prompted many to describe the car as a “velvet hammer.”

In 1970 the Gran Sport GSX packed a 350 horsepower 455 cid V8 with 510 ft-lbs of torque beneath its Ram-Air hood. A special “tight” suspension, 3.64 rear end, front/rear spoilers and graphics with only two available color schemes. 678 GSX model were built in 1970 and only 178 were painted Apollo White, with the balance being Saturn Yellow.
