Jeep announced the Tenth Anniversary Jeep Wrangler Rubicon today. The 2013 Rubicon will arrive in showrooms in the spring of 2013 in both two-door and four-door versions. Based on the normal Wrangler Rubicon / Wrangler Unlimited Rubicon, it will be sold with a six-speed manual or optional five-speed automatic transmission.
As with the standard Rubicon, the part-time four-wheel-drive system has electronic-locking front and rear Dana 44 axles that receive power through a Rock-Trac transfer case with a “4-Low” ratio of 4:1. The standard axle ratio is 4.10:1; Tru-Lok locking differentials are standard. With the manual transmission, the Wrangler Rubicon Tenth Anniversary Edition has an impressive crawl ratio of 73.1:1. (Jeep also lists a 2013 Wrangler Rubicon with the automatic and an axle ratio of 3.73:1.)
The main difference appears to be the half-inch increase in ride height over the standard Rubicon provides the BF Goodrich KM2 265/70R17 tires more room to claw at rugged terrain. Black front and rear steel off-road bumpers toughen up the exterior; the front bumper has a winch-capable design. The removable front bumper end caps help the Wrangler climb obstacles without hindrance, and can prevent damage potential to the bumper system. A dual-intake Power Dome hood helps aid in engine cooling and appearance. Mopar rock rails give added protection from trail damage (Mopar also supplied the black fuel filler door and tail lamp guards). There will be an exclusive color along with silver and white.
