The auto industry is very complicated these days, with constant change across all corners of the globe. The worldwide economic slowdown dictates widespread cost reductions, inspiring partnerships and changes in ownership. Further confusing the scene are past commitments between companies: For example, the new 2011 Jeep Grand Cherokee is based on a Mercedes-Benz platform–even though Chrysler and Mercedes are no longer joined at the hip.
