BMW

BMW started out as a builder of aircraft engines, before moving to motorcycles and finally, cars. Its aircraft engines set speed records in the '30s and its sports cars were stylish, elegant and fast. The horizontally-opposed engines on BMW's motorcycles caught the eye of the U.S. Government and this led to Harley Davidson being ordered to copy them for wartime use. After the war, BMW fought to reclaim its status as a producer of world-renowned sports cars and motorcycles. Today, it's clear that this company has carved out a place among the builders of unique and fast vehicles that many proclaim are the "ultimate driving machine."
