ULEV-2 CARB Emissions Rating
The V-6 engine in the Odyssey meets California's Ultra-Low-Emission Vehicle (ULEV-2) standard for light trucks. Fuel efficiency remains a high priority, as the outstanding city/highway ratings of the Odyssey confirm.
 ULEV-2 (Ultra-Low-Emission Vehicle) models as certified by the California Air Resources Board (CARB).
 19 city/28 highway/22 combined mpg rating for Touring models. 18 city/27 highway/21 combined mpg rating for EX-L and below models. Based on 2013 EPA mileage ratings. Use for comparison purposes only. Your actual mileage will vary depending on how you drive and maintain your vehicle.
Variable Cylinder Management (VCM®)
The VCM® engine is programmed to run on three, four or six cylinders, based on the power requirement (compared to only a 3- or 6-cylinder mode in the previous-generation VCM engines). Powered by the intelligence of i-VTEC® technology, VCM quickly and seamlessly activates or deactivates two or three cylinders. So you get the best of both worlds: V-6 power when accelerating or climbing, and the efficiency of a smaller engine while cruising.
