I am a little unsure if i am reading this correctly but the 89 TTA with a 3.8L V6 was the fastest third gen produced or was it the GTA? could some one be so nice to clarify/explain it?



The fastest 3rd generation Trans Am was the 1989 20th Anniversary Turbo Trans Am. It was selected to pace the 1989 Indianapolis 500, and Pontiac marketed a pace car replica, designating all 20th Anniversary cars as such.
1989 20th Anniversary Turbo Trans Am T-Top(TTA)

The 20th Anniversary Turbo Trans Am Indianapolis 500 pace car replica, (TTA for short), was based on the GTA, but had a high pressure turbocharged and intercooled Buick 3.8L V6, originally developed for the Buick Regal Grand National. 1,555 TTA's were produced, including 39 hardtops and 3 convertibles. The TTA was the quickest Trans Am to date. With a 0-60 time of 4.6 seconds, and a quarter mile time of 13.4 seconds, it was "the quickest 0-60 sprinter available in any US production-car showroom – at any price."[7] The top speed reported by Motor Trend Magazine was 162 mph. It had the highest top speed of any American car available at any price, and the highest top speed of any Trans Am ever built.[8] With better acceleration than the Ferrari Testarossa and Lamborghini Countach, they were considered to be a performance bargain. They were however, the most expensive Trans Ams ever made. Including the option package discount, the MSRP was about $32,000 for a T-top model with leather seats. A buyer could buy three standard Firebirds or one Corvette for the cost of a Turbo Trans Am. The convertible Turbo Trans Am, of which only three were made, cost as much as $38,823.[9]
