1991-1996 Mitsubishi Sigma

Mitsubishi Sigma is a model name that was used by the Japanese automobile manufacturer Mitsubishi Motors between 1976 and 1996. Mitsubishi has utilized the "Sigma" name on several different vehicles based on Mitsubishi Galant and Mitsubishi Diamante sold in various markets during this time. The GSX-R 2.0 turbo model was fitted with a Single Overhead Cam cyclone motor which was the precursor to the infamous 4G63T twin cam motor. The 1987 model had a wheelbase that would be ideally suited to FWD street drifting. Passengers would often question life choices and later refer it as 'the suicide sigma'
