SUBJECT: Permanent All-Wheel Drive
MODEL: 325iX
A high-powered, permanent All-Wheel Drive model, based on the rear-wheel drive 325i, has been developed with only slight modifications to the standard body.
In general, the new 325iX provides improved handling performance via superior transmission of engine power to the road. Directional stability and traction, even under extreme operating conditions, have been improved over those already appreciated in rear-wheel drive cars. The power output is now distributed to a doubled tire contact area.
A transfer case is attached to the rear of the transmission and transmits power to the front and rear axle final drives. The standard 260/5 transmission has a modified output cover with connections for the new single arm shift lever mount as well as attaching points for the transfer case. An opening between the two units provides access to the flexible joint coupling flange connections.
