The two-door Wrangler is configurable in either X, Sahara and Rubicon trim with standard four-wheel drive. The standard 3.8-liter V-6 engine produces 202 horsepower, and the standard transmission is a six-speed manual with overdrive. An optional four-speed automatic with overdrive is available. Electronic stability control with roll control, traction control, brake assist and hill hold control are standard on all Wranglers. The Sahara offers body colour flares, Infinity speakers, remote keyless entry, power window, security alarm and 18-inch wheels. The Rubicon features equipment that off-road enthusiasts usually add anyway, including heavy duty axles, front and rear electronic locking differentials, 32-inch BF Goodrich mud tires, sway bar disconnect system, rock rails and a heavy-duty transfer case with 4:1 low-gear ratio. The available Freedom Top three-piece modular hardtop allows panels to be removed above the driver or passenger. Other options include Dual Top Group, half doors, remote start system, front seat-mounted side air bags, and MyGIG infotainment system with navigation. For 2009, the Sahara receives power windows and power door locks with remote keyless entry as standard equipment.
