1989 Pontiac Firebird 20th Anniversary Trans Am

To combat the rising thefts targeting Firebirds and Camaros, GM introduced a 'pass key' security system in all 1989 models, inspired by the GTA. This system required a resistor pellet in the key to match the ignition lock's coding; otherwise, the starter would be deactivated temporarily. However, this was just one of the many advanced features of the 1989 Pontiac Firebird 20th Anniversary Trans Am.

High-performance coupes were equipped with four-wheel disc brakes. Formula and Trans Am Firebirds now featured air conditioning as standard. GTA tires were upgraded to "Z" rating (capable of speeds over 149 mph) from the previous "V" rating (130 mph), though the tire size remained unchanged at 245/50R16. The GTA was available in both hatchback and notchback styles, with the latter being a $700 add-on. Additionally, a compact-disc player became an optional feature.

In 1989, the Trans Am marked its 20th anniversary with a special edition featuring a turbocharged 3.8-liter V-6 engine under the hood. This powerful 250-horsepower turbo, previously seen in Buick's Grand National and GNX, delivered an impressive 340 pounds-feet of torque, enabling 0-60 mph acceleration in just five seconds or less. This thrilling performance came at a premium, costing $10,000 more than the GTA, yet approximately 1,500 enthusiasts were willing to pay for the experience.

The 20th Anniversary Trans Am, one of the most powerful models ever produced, was exclusively available with an automatic transmission. Its sleek white body was free of flashy racing stripes, featuring only understated "20th Anniversary" cloisonne emblems and "Turbo Trans Am" badges. A standard Anniversary edition was chosen as the pace car for the 73rd Indianapolis 500.
