GHG Vehicle Test Group

GHG Vehicle Test Group

GHG Vehicle Test Group means vehicles that have identical test group, vehicle make and model, transmission class and driveline, aspiration method (e.g. naturally aspirated, turbo-charged), camshaft configuration, valvetrain configuration and inertia weight class.

Since the 2001 model year, light-duty vehicle engine families are known as "test groups". [ http://www.eere.energy.gov/afdc/afv/conversion101.html] There are many different test groups; for example, the Ford F-150 could have 10 or more test groups, depending on the engine size, gross vehicle weight, and drivetrain of the vehicle.
