A Datsun 280ZX, specifically the 1979 model, has an engine rated at 135 horsepower.
The 1979 Datsun 280ZX Horsepower Rating
The Datsun 280ZX, which debuted for the 1979 model year, was engineered to produce 135 horsepower from its inline-six engine. This power output was a direct result of design choices and regulatory requirements of the era.
Key factors contributing to this rating included:
- Emissions Compliance: The addition of a catalytic converter was a significant change made to meet evolving environmental regulations.
- System Recalibration: To integrate the new emissions equipment effectively, the ignition and fuel-injection systems were recalibrated. These adjustments ensured the vehicle met required standards while optimizing performance within those constraints.
Horsepower in the Z-Car Lineage
The 280ZX continued the legacy of the popular Datsun Z-car series, building on the foundation laid by models like the 240Z, 260Z, and 280Z. While the 280ZX evolved to offer more luxury and refinement, its performance remained a defining characteristic.
To provide context for the 280ZX's output, consider the comparison with its immediate predecessor:
| Model Year | Horsepower (hp) | Notes |
|---|---|---|
| 1979 Datsun 280ZX | 135 | Engine rating for this model year, influenced by emissions control additions and system recalibration. |
| Datsun 280Z (earlier) | Approximately 149 | This estimate is based on the 1979 280ZX's output being 14 horsepower less than the previous 280Z model. |
The slight reduction in horsepower for the 280ZX compared to the 280Z was primarily a consequence of these necessary modifications to comply with the stricter emissions standards of the late 1970s. Despite this, the Datsun 280ZX was well-regarded for its balance of performance, style, and comfort.
