1989 Pontiac Trans Am GTA

1989 PONTIAC TRANS AM CHANGES & IMPROVEMENTS
Visually, the '89 T/A was nearly identical to the 1988 model. New Lexan T-Tops with a 'bubble-top' profile replaced the former glass units. Many were replaced with glass T-tops under warranty because they didn't hold up well in the sun. GM introduced its Vehicle Anti-Theft System (VATS), essentially a computer chip embedded in the ignition key that had to send a signal to the ignition switch for the car to start. This made it much more difficult to steal the cars, it was very effective. The rear disk brakes increased in diameter and a new PBR calipers.
1989 PONTIAC 20th ANNIVERSARY TURBO TRANS AM
The Trans Am was selected to do Pace Car duty at the 1989 Indianapolis 500. To commemorate this, Pontiac came out with the 20th Anniversary Turbo Trans Am (TTA). Based on the 1989 Pontiac Trans Am GTA, the TTA used a 3.8-liter Buick V6 with turbo charger, similar to that used in the Buick Grand National. These were actually almost identical to the actual Indy Pace Cars, less the added safety equipment required to pace the Indy.


1989 Pontiac Trans Am GTA INTERIOR

1989 PONTIAC TRANS AM INTERIORS
The GTA editions all got the premium leather interior and all the best appointments. Standard 1989 Pontiac Trans Am interiors were also quite nice, with high-quality fabrics and carpeting.
1989 TRANS AM ENGINE OPTIONS
Of course, the big new was the hot new 3.8 Turbo. But on the V8-front, a new dual catalytic converter exhaust system was made available on top-line 5.0 and 5.7 V8 which improved flow enough to increase horsepower by 13%.
