2018 Jeep Wrangler Sahara Unlimited
Engineered to master the most challenging off-road tracks, Jeep Wrangler is the result of more than seventy-five years of leadership in the development of 4×4 systems. Two four-wheel drive systems are available: Command-Trac – on the Sport and Sahara trim levels, and Rock-Trac – standard on the Rubicon trim configuration, the most rugged and capable model for off-road driving. Both systems feature the new Selec-Trac full-time two-speed transfer case for a continuous monitoring and management of the torque sent to front and rear wheels.
In details, Command-Trac four-wheel drive system features a two-speed transfer case with a 2.72:1 low-range gear ratio, heavy-duty next-generation Dana front and rear axles with 3.45 rear axle ratio for the petrol version, and 3.73 for the diesel versions.
