Gran Sport Statistics

The Buick Gran Sport or GS was a high-performance option package available on Buick’s intermediates from 1965 until 1974.

Sale were never as large as some of the other traditional muscle cars like the chevelles, and Road Runners but performance was always impressive. Some of the bext performaing cars of the entire muscle car era sported a Gran Sport badge.

For example, GSX performance was equal to that of the ‘Hemi’ ‘Cuda with a much more luxurious car. This was partly due to the light weight build of the 455 which weighed roughly 150 lbs less than the Chevrolet 454. Quarter mile times in the 13.30s were reported in numerous magazines in 1970.
