The HVAC scoop is still present along with the scupper vents on the enclosed models. The Burgundy Metallic color has been dropped. Stainless steel wheel covers are available to give the wheels a little flash. HID lights are also available along with the usual roof rack, tire carriers, and winch.

Technical Article

Gear Reduction
October 1, 2005

Summary: The purpose of this series of articles was to examine the mechanics of how our vehicles more around. They are made up of several interesting elements that combine to give us torque, speed, power, and linear force.
