Nissan Datsun 260Z (1974 to 1978)

The Datsun 260Z was sold in the United States for the 1974 model year only, but was available in other countries until 1978. As compared to the Datsun 240Z, the engine was enlarged .2 L to 2.6 L by lengthening its stroke. In the US, federal emissions regulations forced a reduction in ignition timing and compression ratio, resulting in a lower power output (140 hp) for the 260Z despite the additional displacement, whereas in other countries the power output increased to 165 hp (123 kW; 167 PS). There was also a 1974.5 model sold through the second half of 1974 in the US that had the full 165 hp and the addition of larger safety bumpers. In the US, for the 1975 model year, the 240Z was replaced by the Datsun 280Z. It would continue in production for other markets until 1978.
