👋 Introduction

Market Position:

The 2015 Jeep Wrangler (JK) solidified its position as the quintessential go-anywhere, do-anything off-road vehicle, catering to adventure enthusiasts, off-roaders, and those seeking a rugged, iconic American utility vehicle.

Model Evolution:

The JK generation, introduced for the 2007 model year, represented a significant evolution for the Wrangler. It transitioned to a coil-spring suspension for all models (previously front torsion bars on some variants), adopted the modern Pentastar V6 engine in 2012, and offered both 2-door and 4-door (Unlimited) configurations, expanding its appeal. The 2015 model year saw minor updates and trim packaging refinements.
