Previously the H platform designation was used for unrelated rear-wheel-drive compact cars.
Many H-bodies used GM'* large 3800 V6, and supercharged versions were available from 1991 to 1999. They originally came in both 2-door and 4-door versions, but the four-door sedans were dramatically more popular, and two-door models were dropped by 1992.
According to one source, the H-Body sedans were the next "big thing" for GM, and development cost more than $3 billion, which is on par with roughly how much Ford invested in the Ford Taurus. Both the H-body sedans and the Taurus (based on the D186 platform) were launched fully in 1986.
Starting in 2000, all H-body vehicles moved to the G platform, however GM continued to call it the H platform.
