Re: Is my jeep 4 wheel or all wheel drive?
Laredo 4wd have Quadra trac1 mp2010 (magna) full time 4wd 50/50 tq split all the time, no 4-lo
limited, overland, summit have quadra trac 2, mp3023 t-case. in auto it is 60/40 split, snow 50/50, when in sport 80/20. t-case has low range and can change the ratios to match conditions ie loss of traction.
per qd2 rear diff, only available on 2015(not sure on the other years) on hemi or diesel. standard on Summit but added cost on the others. I sprung for it as stand alone, was 782$, could also get OR2 with it included but I wanted the 20" wheels.
Anyhow, these rigs use the abs sensors to detect loss of traction and differences in wheel speeds to apply brake traction control,and adjust amount of tq front to rear and side to side on the rear axle if QD2.
Very advanced system, but tires make all the difference.
