We’re working towards a greener future.

Here’s how you can help.

In-Use Verification Program

Your Toyota or Lexus may be eligible to participate in our emissions and fuel economy test program. If your vehicle gets selected, we'll pick it up, give you a loaner vehicle, and return it to you washed and with a full tank of gas. We'll even pay you for your time. Learn more about our In-Use Verification Program (IUVP) below or contact us at iuvp@toyota.com.

Why do we test?

All in-use testing is performed at one of three facilities in the United States: California, Colorado and Michigan. Third-party contract companies are used to procure owner vehicles on behalf of Toyota and Lexus.

What are we testing?

Exhaust Testing

All selected vehicles are placed on a chassis dynamometer, also known as a dyno. The dyno simulates various driving styles, and allows the vehicle to be driven while remaining stationary, like a person running on a treadmill.

During each drive cycle, analyzers are connected to the tailpipe to measure exhaust gases and fuel economy.

City driving is simulated by a cycle called the Federal Test Procedure (FTP). The cycle has an average speed of 21.2 mph, lasts approximately 30 minutes, and is conducted in three phases.

Highway driving is simulated by the Highway Fuel Economy Test (HFET or HWY). This test has an average speed of 48.3 mph and lasts just under 26 minutes.

The US06 cycle was created to test vehicles under high speeds and acceleration conditions that more closely resemble modern driving habits. The test lasts 20 minutes with an average speed of 48.4 mph and a brief high speed of 80.2 mph.

<h3>Evaporative Testing<h3> image
Some vehicles are also tested for evaporative emissions, or vapors off-gassed by the vehicle. This testing simulates two scenarios: parked and refueling.


We'll take care of everything.

Toyota performs a vehicle inspection for eligible vehicles that are selected for testing. If a vehicle is accepted, it is insured by Toyota or the procurement company until it is returned to the owner. All vehicles are stored inside for the duration of the program when not being tested. On average, vehicles are returned within 1-2 weeks with an additional 100-150 miles on the odometer.

A monetary incentive is provided based on make, model and sales volume.

The vehicle is cleaned, washed and returned with a full tank of gas.

A comparable loaner vehicle is provided for the duration of the program.

Frequently
Asked
Questions

  • Do I have to participate in the program?

    No, participation in the program is completely voluntary.

  • Why should I participate?

    Along with the incentives (free tank of gas, car wash, monetary incentive ($$$), potential replacement parts and a loaner vehicle with a full tank of gas), you will also be helping Toyota, Lexus, and the EPA improve air quality by monitoring emissions.

  • When will I receive my incentive check?

    The incentive check is issued to you when the vehicle is returned.

  • How long will the testing take?

    Testing usually lasts between 1-2 weeks depending on the required number of tests. Vehicles are generally returned within one business week (5 days).

  • What happens to the information collected during testing?

    The results of this program are submitted to the EPA and used to determine the emissions performance of in-use vehicles. If a major issue is found for a specific vehicle or group, further investigation may be required.
