For 1974 a 1.8-liter engine replaced the 1.7 and had a new type of electronic fuel injection called AFC (air flow control), or ‘L’ Jetronic. This same basic injection was used on 911s in the late-’80s. Unfortunately, due to emissions regulations, the 1.8 made just 76 hp, less than the smaller engine it replaced. The standard steel wheels were changed to 5.5-inch wide VW units. Rubber bumper guards now adorned the rear and the headlight surrounds were changed from white to black plastic. US cars got the infamous ignition seat-belt interlock buzzer. This was also the year of the limited edition series.
