The 92-X was available in 2005 & 2006.

The 92X Linear is the non turbo, 2.5l H-4. 2005 92-X Aero is a turbocharged 2.0l H4. The 2006 92-X Aero might be a 2.5l turbocharged H4.

The Saab 92X is a reskinned Subie Impreza.

Differences:

Seats. The seats in the 92x are less sporty than the WRX, less side bolstering.

Sound Deadening. The 92x has tons of foam sound deadening. At idle, I can't tell if my 92x's engine is running or not.

The 92X-Aero is the same as the WRX except for the steering rack. The steering rack on the 92X-Aero is from the WRX-Sti.
