Moving forward. With your help.
The In-Use Verification Program (IUVP) tests the emissions of road-driven Mercedes-Benz vehicles like yours so we can help improve our environmental impact.
Volunteering Your Vehicle
By allowing us to test your Mercedes-Benz, you'll be helping us deliver cleaner air and a smaller carbon footprint. We've made our process as convenient as possible
Safe and Easy Transport
Don’t live near a testing center? We can transport your vehicle.
Upgraded Loaner Vehicle
You’ll enjoy the use of a newer, upgraded Mercedes-Benz vehicle.
Complementary Service
We’ll clean your vehicle inside and out and top up the gas.
Gift Card
At the end of the process, we'll send you a gift card — our way of saying thanks.
Eligible Vehicles
We’re looking for Mercedes-Benz or Mercedes-AMG vehicles that meet the following criteria:
- Vehicles with around 50,000 miles or more and 4 years of service
- Vehicles with around 10,000 miles or more and 1 year of service
- Bluetec and diesel vehicles with around 100,000 miles
Interested in participating?
Check for eligibility by emailing us with the link below, and we’ll be in touch. You can also email us with any questions you might have.
How Testing Works
The emissions test measures emissions performance against standards set by the U.S. Environmental Protection Agency (EPA) and the California Air Resource Board (CARB). Testing is designed to simulate real-world conditions and covers two areas: 1. exhaust testing; and 2. evaporative testing.
Exhaust Testing
We test emissions while simulating different driving conditions. Your vehicle sits on a dynamometer (basically a treadmill for vehicles), and we connect a hose to the exhaust pipe to monitor different speeds and acceleration patterns. In some cases, your vehicle may be driven on the road. We’ll notify you in advance if we need to test your vehicle on the road.
City
Simulates stop-and-go driving, with an average speed of 20 mph and maximum of 60 mph. Runs about 30 minutes.
Highway
Simulates steady driving, with an average speed of 50 mph and a maximum of 60 mph. Runs about 15 minutes.
Supplemental
Tests against the Federal US06 Test Cycle, with an average speed of 50 mph and a maximum of 80 mph. Runs about 10 minutes.
Evaporative Testing
These tests cover scenarios where your vehicle is parked, e.g., when the vehicle is not in use or when refueling. Two different types of chambers are used to measure these emissions.
SHED
The Sealed Housing Evaporative Determination chamber measures the level of vapors given off by the vehicle and any of its components.
ORVR
The On-board Refueling Vapor Recovery chamber measures vapors given off while refueling.
