There are a few key differences between the Rubicon and Sahara models of the Jeep Wrangler. The Rubicon is designed for off-road performance, with features like Dana 44 front and rear axles, electronic locking differentials, and 32-inch tires. The Sahara is more geared towards on-road driving, with features like a body-colored hardtop and fender flares, 18-inch wheels, and automatic climate control. Both models come with a 3.6L V6 engine and four-wheel drive, but the Rubicon has a slightly higher ground clearance and towing capacity.
