Mitsubishi Galant GTO
To fight other Japanese companies in the profitable compact sports car market, Mitsubishi introduced the Galant GTO in 1970 as their affordable sports coupe. The car was built on a Galant sedan platform, sharing all critical components and dimensions (via Mitsubishi Motors).

However, the Galant GTO had its own range of four-cylinder engines ranging from the diminutive 1.6-liters to 2.0-liters fed through multiple carburetor setups. The power output was only a mere 100 HP. However, it looks cool and is somewhat desirable to collectors.
