1978 Pontiac Trans Am

1978 was a record year in sales for the Pontiac Firebird and Trans Am, hitting a whopping 187,285 units sold between them. So what made this car so special that it pleasantly surprised many with its sale numbers? The 1978 model itself was largely unchanged from the previous year, but under the hood, the story was a little different. The horsepower increased for the 1978 model year. Previously, new regulations on fuel economy and emissions had made adding horsepower difficult for many car companies, but some were beginning to get the hang of incorporating more power, even with those regulations.
