In a self-aggrandizing statement FCA has claimed that the all-new 2018 Jeep Wrangler is the most capable and recognized vehicle in the world that builds on its legendary history.
FCA said that the 2018 Jeep Wrangler delivers unmatched combination of off-road capability, authentic Jeep design, open-air freedom, advanced fuel-efficient powertrains, superior on- and off-road dynamics, and a host of innovative safety and advanced technology features.
The 2018 Jeep Wrangler 2-door model is available in three different trim configurations: Sport, Sport S and Rubicon. Wrangler 4-door models are available in four different trim configurations: Sport, Sport S, Sahara and Rubicon.
The 4×4 capability
The all-new 2018 Jeep Wrangler delivers legendary off-road capability courtesy of two advanced 4×4 systems, and for the first time in Wrangler’s history, a two-speed transfer case with full-time four-wheel drive and a 2.72:1 low-range gear ratio that is available on Sahara models. This new Selec-Trac full-time two-speed transfer case is intuitive and allows the driver to set it and forget it, while constantly sending power to the front and rear wheels.
The Command-Trac 4×4 system features a two-speed transfer case with a 2.72:1 low-range gear ratio, and next-generation solid Dana front and rear axles with a 3.45 rear axle ratio.
On Wrangler Rubicon, a Rock-Trac 4×4 system features heavy duty next-generation Dana 44 front and rear axles with a “4LO” ratio of 4:1. A 4.10 front and rear axle ratio is standard as are Tru-Lok locking differentials.
Wrangler Rubicon models offer improved articulation and total suspension travel versus the previous generation with help from an electronic sway-bar disconnect. With the standard six-speed manual transmission, Wrangler Rubicon has an impressive and improved crawl ratio of 84.2:1, and 77.2:1 on Rubicon models equipped with the new eight-speed automatic transmission – both of which makes scaling any obstacle on the trail easy.
Both Command-Trac and Rock-Trac systems offer full-time torque management, enabling optimal grip in low-traction conditions.
An available Trac-Lok limited-slip rear differential provides extra torque and grip during slippery, low-traction situations, such as driving over sand, gravel, snow or ice.
