smartway logoSmartWay Opportunities for Manufacturers

Original equipment manufacturers (OEMS) of long-haul tractors and trailers can request that EPA evaluate their equipment to assess whether it meets certain environmental and efficiency specifications established by the EPA SmartWay program. Tractors and trailers that meet SmartWay's specifications are eligible to use a EPA-designated SmartWay logo that signified their efficiency and improved environmental performance.

EPA has also determined that certain idling reduction, aerodynamic, retrofit and tire technologies provide verifiable fuel saving and/or emission reducing benefits when used properly in their designed applications. For such tractor/trailer components, EPA uses test procedures to verify that fuel savings and emissions benefits match equipment manufacturers claims.

This page provides detailed information about getting tractors/trailers tested and deisgnated SmartWay or have componenents verified by EPA.

What are EPA-designated SmartWay Tractors and Trailers?

They are long-haul truck components which significantly lower emissions and fuel consumption. EPA and leaders in the freight equipment-manufacturing industry worked together to develop these performance specifications.

When manufacturers equip long-haul tractors and trailers with these specifications, they are designated and labeled as "US EPA Designated SmartWay." The US EPA Designated SmartWay label may be used at point-of-sale and applied to the interior of the tractors and trailers by the equipment manufacturers.

What are the basic specifications for an EPA-designated SmartWay Tractor?

Interim requirements for designated SmartWay Tractors, and interim guidance and an interim test method for verifying SmartWay components are available. Basic qualifications for a designated SmartWay Tractor include:

  • Model Year 2007 or later engine;
  • Integrated sleeper cab high roof fairing;
  • Tractor-mounted side fairing gap reducers;
  • Tractor fuel-tank side fairings;
  • Aerodynamic bumper and mirrors;
  • Options for reducing periods of extended engine idling (auxiliary power units, generator sets, direct fired heaters, battery powered HVAC system, and automatic engine start/stop system); and
  • Options for low-rolling resistance tires (single wide or dual), with aluminum wheels encouraged but optional
What are the basic specifications for an EPA-designated SmartWay Trailer?

New long-haul van trailers can be ordered, and existing trailers can be upgraded, to qualify as an EPA-designated SmartWay Trailer provided that they are equipped with:

  • Side skirts;
  • Weight-saving technologies;
  • Gap reducer on the front or trailer tails (either extenders or boat tails); and
  • Options for low-rolling resistance tires (single wide or dual), with aluminum wheels encouraged but optional

Technology Manufacturers: Verify Your Equipment as SmartWay

The Technology Verification Program evaluates the performance of vehicles, technologies and equipment that are intended to reduce greenhouse gases and other air pollutants when submitted by manufacturers. The verification process includes a thorough review of the technologies and/or strategies as well as test data from prescribed test protocols to establish credible performance and ensure efficiency improvement.

"You will need Adobe Reader to view some of the files on this page. See EPA's PDF page to learn more."

Considerations before applying for verification:

  • Manufacturer Representative: The applicant for verification must be a manufacturer representative with detailed knowledge of the technology, its manufacture, in-use operation, performance, durability and prior testing. The manufacturer representative is responsible for attesting to EPA that information is correct and that the technology will be manufactured, installed and perform as described.
  • Regulatory Requirements: Some technologies may not qualify for verification as the product may have regulatory requirements that supersede verification.
  • Availability: The technology submitted for verification must be commercially available for installation. No products still in the research and development stage will be verified.
  • Health Effects and Safety: Concerns with health effects or safety may need to be addressed prior to EPA review of a technology for verification.

Verification Process:

  1. Apply for Verification: This is a two-step verification process. To begin the verification process, manufacturers must first complete Part 1 of the application (5 pp, 567K, February 2012) and submit it to Tech_Center@epa.gov.
    Part 1 of the application is used by EPA as an initial review of the verification request. If the technology or strategy falls under one of the categories listed below, EPA will follow up with Part 2 of the application requesting specific information for further review. The application forms outline the information required for verifying a technology or strategy. EPA has determined the following types of technologies provide fuel saving and/or emission reducing benefits when used properly in their designed applications for class 8 long-haul trucks:
        • Aerodynamics
        • Idle Reduction
        • Low Rolling Resistance Tires
  2. Application Acceptance: Once the manufacturer has submitted the two-part application and addressed the follow-up questions from EPA, the application will be accepted.
  3. Verification Test Protocols: A test protocol will be used for the specific technology for its intended applications. The testing protocols are listed as following:
  4. Testing: For aerodynamic and tires technologies, the manufacturer must follow the verification protocols provided above and submit the test results to EPA. For idle technologies, the manufacturer must submit product information and test results to EPA for review.
  5. Test Information and Results: Once testing is complete, test results must be sent to EPA in formats described by EPA. EPA will review the data to determine if the technology qualifies for verification.
  6. Notice of Verification Letter: Upon verification of the technology, the manufacturer will receive a Verification Letter. Sample Verification Letter (PDF) (2 pp, 458K, March 2012)
  7. Verified Technologies List: Once the technology has been verified, EPA will add it to the Verified Technologies Lists (Aerodynamic Technologies List, Idle Reduction Technologies, and Low Rolling Resistance Tires). The list describes the technology and other information contained in the Verification Letter so that potential customers may determine if they wish to purchase the technology. The SmartWay Verified Technologies Communication Guidelines provide information on communicating your organization's involvement in the U.S. EPA SmartWay Transport Partnership.
  8. Verified Technologies and Changes: Products sold as verified technologies must be produced and installed as described to EPA. If a manufacturer changes a verified technology or implements changes relative to information provided to EPA, the manufacturer must update the documentation with the Verification Program. If EPA determines the changes may impact performance or the changed technology may not be represented by the original verification, EPA may require further testing or conclude the changed product requires a separate verification.

    SmartWay Truck Emissions Test Protocol

    EPA's SmartWay Transport Partnership is collaborating with the transportation industry to develop a SmartWay Truck Emissions Test Protocol that effectively quantifies the benefits of various heavy vehicle designs and technologies. The goal is to create a standard test protocol that compares the emissions and fuel-efficiency of heavy-duty vehicles.

    Right now, no such standard test protocol exists. Without an objective, stand-alone test protocol, it is difficult to develop a common understanding of how to assess criteria air pollutants, greenhouse gases, and fuel-efficiency of heavy-duty vehicles, including advanced vehicle designs and components. Having this information would help the Agency establish performance-based eligibility criteria for the next generation of SmartWay trucks, and to quantify the benefits of hybrid vehicles.

    EPA has developed the SmartWay Truck Emissions Test Protocol (PDF) (76 pp, 900K, EPA-420-P-07-003, November 2007)as a starting point for discussion among stakeholders. This working draft is a first step toward a performance-based specification that would be technology-neutral, able to quantify a broad range of heavy vehicle configurations and applications, and able to measure technical innovations as they emerge. EPA is soliciting additional information and critical input to address areas of uncertainty and clarify outstanding issues.  

    Technical Presentations from the March 19-20, 2008 Testing Protocol Workshop

    EPA held a public workshop in Washington, DC, on March 19-20, 2008, to discuss the protocol. The purpose of the workshop was to present the current working draft, provide highlights of comments received to date, and to invite further collaboration with interested parties to further develop and validate the test procedure. The Agency appreciates the valuable oral and written comments it received before and during the workshop.

    To provide for the broadest public input, EPA accepted comments, test data, analyses, and other input through April 30, 2008.
