In 1987 the Pontiac Firebird Trans Am GTA was unveiled, it was the American automaker’s top-of-the-line sports car with an engine borrowed from the C4 Corvette and the WS6 high-performance handling package fitted as standard.
Americans looking for a sports car in the 1980s had a broad selection to choose from including models made in Japan, Germany, Italy, Britain, and the USA. The Firebird Trans Am would be a popular choice, helped along by the fact that the model was used as KITT in the “Knight Rider” TV series.
The mid-to-late 1970s has been called the “Dark Ages of Horsepower” by some, it was a time when increasing emissions restrictions resulted in significant drops in horsepower, but by the mid-1980s that power was being slowly clawed back.
The GTA is powered by the 5.7 liter (350 cubic inch) Tuned Port Injection (TPI) V8, it’s very similar to the engine used in the C4 Corvette – the biggest difference being that the C4 got aluminum heads and the GTA got cast iron.
In 1987 Pontiac released the Firebird Trans Am GTA as their new halo model. It was based on the pre-existing Firebird Trans Am but it came with the 5.7 liter (350 cubic inch) Tuned Port Injection (TPI) V8 that was being used in the C4 Corvette.
The one key differences between the Corvette and Firebird versions was that the Corvette heads were aluminum and the Firebird heads were cast iron.
This engine would be mated to the TH-700R4 (4L60) automatic transmission which came as standard, air conditioning was included as were newly styled seats with inflatable lumbar and side bolsters, a GTA horn button, special badging, the WS6 performance handling package, and perhaps most noticeably, a color-colored body kit.
WS6 performance handling package included 36mm sway bars up front with 24mm sway bars in the rear, a quick ratio steering box, gas filled struts, and 16 inch wheels with 245/50R16 tires on all four corners.
The interior of this car is a retro dreamscape, with plenty of 80s-style buttons, sliding graphic equalizer adjusters on the stereo, and even an early car phone.
With 250 bhp and 315 ft lbs of torque the Pontiac Firebird Trans Am GTA wasn’t a particularly powerful car by modern standards but in the 1980s, as the world recovered from the extreme emissions-related horsepower losses of the 1970s, the power must have seemed like a breath of fresh air.
The car you see here is a Pontiac Trans Am GTA from 1988 – just the second year of production. t’s finished in red with a grey interior, two-piece gold/chrome wheels, and of course, that color-coded body kit.
This is a one-owner vehicle with 17,913 miles on the odometer and receipts to verify the mileage. It comes with the window sticker and it’s fitted with the automatic transmission – as most of them are.
