Pontiac Trans Am 20th Anniversary
In 1989, Pontiac was celebrating the 20th anniversary of its favorite muscle car – the Trans Am. What was a better way than to introduce a very limited run of 1500 cars to commemorate the occasion? But, the anniversary editions have to have a twist and not be just another decal and paint job. Pontiac decided to install Buick’s 3.8-liter turbo V6 from GNX and create the fastest Trans Am of the decade (via Motorious).
The white commemorative edition could accelerate 0.1 seconds faster from 0 to 60 mph than GNX at 4.6 seconds. The reason was pretty simple, better weight distribution and gearing from the Pontiac gearbox.
