ISO 1585:2020 is an international standard that provides guidelines for testing and determining the net power of road vehicle engines. The standard is essential for ensuring that engine power ratings are consistent, accurate, and compliant with international automotive standards. This standard applies to the measurement of engine power in road vehicles, which is a critical parameter for manufacturers, regulatory bodies, and consumers in assessing engine performance.
The standard’s full title, “ISO 1585:2020 Road Vehicles — Engine Test Code — Net Power”, describes the testing procedures to measure and evaluate the net power output of an engine in a way that is both standardized and reproducible. This allows for consistency across different manufacturers, engine types, and test conditions.
Net power refers to the usable power output of an engine after accounting for losses due to engine accessories such as the alternator, water pump, and air conditioning compressor. It is the engine’s power measured at the output shaft, typically expressed in horsepower (hp) or kilowatts (kW).
Net power is a key parameter for manufacturers as it helps define an engine’s performance, fuel efficiency, and suitability for specific vehicle applications. It is a critical factor that influences vehicle design, marketing, and regulatory compliance.
ISO 1585:2020 establishes a standardized test code for measuring net engine power in road vehicles. The standard aims to ensure that all testing is carried out under similar conditions, providing accurate, reproducible, and globally acceptable results. The test procedure outlined in this standard applies to both internal combustion engines and hybrid powertrains commonly found in road vehicles.
This test code is essential for ensuring that vehicle power ratings are consistent across markets and manufacturers. It helps regulatory bodies to assess compliance with emissions and performance standards, while also ensuring that consumers can trust the power ratings provided by vehicle manufacturers.

Benefits of ISO 1585:2020
- Standardization:
- The standard ensures that all vehicle manufacturers use the same testing methods for measuring net engine power. This helps eliminate discrepancies in test results and provides a clear, consistent way to compare the power ratings of different vehicles and engines.
- Global Acceptance:
- ISO 1585:2020 is recognized globally, enabling manufacturers to market their vehicles in international markets without the need for additional testing or certification. This is particularly important for multinational corporations that need to comply with regulations across different regions.
- Transparency and Consumer Confidence:
- By adhering to standardized testing methods, manufacturers provide consumers with accurate, reliable information about engine performance. Consumers can trust that the power ratings provided by manufacturers are comparable across different brands and models.
- Regulatory Compliance:
- ISO 1585:2020 helps ensure that manufacturers meet the regulatory requirements for vehicle performance and emissions in various countries. The standard is often used by regulatory authorities to verify that vehicle power ratings are in compliance with national or regional laws.
- Enhanced Performance Benchmarking:
- Manufacturers can use the data obtained from ISO 1585-compliant testing to improve engine performance. The standard allows for accurate benchmarking of net power, which is a crucial factor in designing engines with optimal fuel efficiency, emissions, and overall performance.
- Improved Vehicle Design:
- By following ISO 1585:2020, manufacturers can ensure that their vehicle designs are based on reliable and standardized power data. This helps in creating engines that meet the performance expectations of consumers while also being compliant with environmental regulations.
Who Should Use ISO 1585:2020?
- Vehicle Manufacturers: Automotive companies involved in the production of road vehicles will use ISO 1585:2020 to test and report the net power output of their engines.
- Engine Manufacturers: Companies that design and manufacture engines for road vehicles, including internal combustion engines and hybrid powertrains, will rely on this standard to measure and report their products’ performance.
- Testing and Certification Agencies: Regulatory bodies and third-party certification organizations can use ISO 1585 to verify that manufacturers comply with net power measurement standards.
- Automotive Engineers: Engineers involved in designing, developing, and testing vehicle engines will utilize this standard for accurate power measurement and performance benchmarking.
- Consumers and Automotive Enthusiasts: Consumers looking for standardized performance data can refer to the net power measurements as provided by manufacturers, knowing they are based on ISO 1585 standards.
ISO 1585:2020 is an essential standard for anyone involved in the design, production, testing, or certification of road vehicle engines. By providing clear and standardized testing protocols for measuring net engine power, this international standard ensures that power ratings are accurate, consistent, and globally acceptable. Manufacturers benefit from the ability to meet regulatory requirements, improve product performance, and build consumer confidence. As vehicle powertrains evolve and new technologies such as hybrids and electric vehicles become more common, standards like ISO 1585:2020 continue to play a key role in maintaining consistency and transparency across the automotive industry.
