Most vehicles have significantly more fan noise in recirculate than in normal/outside air mode. Although the noise is greatly increased, I don't know of any cars that actually have a higher fan speed that is limited to recirculation mode.
A number of cars that will change fan speed to high automatically when you switch to recirculate. The PT does not do that. Is that what you mean?
