They use the EVAP canister, located in the rear of the car. It's a completely different type of system, it purges and filters based on solenoid control as well as engine vacuum, and flow is dictated by fuel temperature, ambient temperature, and other factors. The basic charcoal canisters purge all the time based on vacuum only.
If the car has a charcoal canister under the hood, beside the airbox, it's OBD-I.
