Colorado Emissions

[Leon R]

Most states exempt AWD vehicles from the roller test, because it isn't as safe to perform. Was CO actually testing VX on 2WD rollers?

No, Colorado has a lot of AWD vehicles so they have a couple of lanes that are specifically made for AWD. It depends on the vehicle what method they use though. I've got a Subaru WRX that goes on the rollers but my VX they took to the side and ran the no load tests.

Just FYI for Colorado peeps with large tires.

Q.
Tire Sizes and Dynamometers?
A.

Front wheel and all wheel drive vehicles with low profile tire sizes 17 inches or larger in diameter, or vehicles with tire sizes larger than 34 inches cannot be safely tested on the dynamometer.

Only vehicles with manufacturer-equipped undersized or oversized tires that do not fit safely on the dynamometer will be authorized by the state to undergo an idle test instead of a dynamometer test. Vehicles with tires larger or smaller than original equipment that do not fit safely on the dynamometer must be returned to stock condition for testing. Vehicles with non-original undersized or oversized tires will not receive authorization from the state for an idle test.

I had to take the Vulva to the AWD lane but I'm pretty sure the wheel base in it is longer then a VX.

That's why I register the VX in Colorado Springs where they happily accept your money without emissions.
