 Essentially abandoning the intermediate designation in favor of becoming mid-size vehicles, the A-body vehicles adopted a footprint slightly smaller than the X-body compacts.In a reduction similar to the full-size model lines, the A-body downsizing shed approximately 12-15 inches of body length and 500-1,000 pounds of curb weight (depending on model configuration).In 1982, GM downsized several of its mid-size sedans, as the A-platform shifted to front-wheel drive; the remaining A-platform variants (two-door coupes and coupe utilities) were redesignated under the GM G-platform.
