7. Pontiac Trans Am GTA
The Trans Am was the hottest version of the third generation Pontiac F-body. Pontiac introduced it in 1987 as their top-of-the-range Firebird offering. The package was available until 1992 in limited numbers. The secret weapons of the GTA were its engine and WS6 handling package.
The engine was a 350 V8 with 210 HP in early models and up to 245 HP in later versions. The rumor was the engine was the same as the Corvette. They used the same TPI fuel injection system and displacement, but not similar motors. The Corvette had aluminum heads while Pontiac used iron cast ones.
However, power and performance were similar. The WS6 package offered unmatched road holding and braking capabilities. It consisted of four disk brakes and a stiffer suspension. The WS6 also came with special wheels and performance tires.
