Mazda, originally the Toyo Cork Kogyo Co, was founded in 1920, although the name "Mazda" was not formally adopted until 1984. Ford became the major shareholder in the 1970's due to financial crisis, however the 70's and the 80's were to become the heyday for Mazda which catapulted them from a niche Japanese manufacturer to a major player in the world auto industry. Mazda was unique amongst car manufacturers by pioneering the rotary or "wankel" engine technology in their vehicles. Today Mazda are still using this rotary technology in their sports coupe the RX-7 and have committed serious investment in future technologies by the creation of the Mazda Research and Development of North America Inc. - a company with bases in Irvine, California and Flat Rock, Michigan. This is in addition to their main research and development HQ in Hiroshima, Japan. Mazda currently has a U.S. market share of just 1.5%. However Ford are reported as being concerned that Mazda, despite $20 billion of sales is continuing to lose money. The SUV range (CX-&, CX-9 and Tribute) consist of small to mid sized SUVs with highway economy ranging from 22-30 MPG with the most economical model being the 5 seat Mazda Tribute Hybrid. Despite good results in terms of reliability and customer satisfaction in surveys such as J.D. Power, the Mazda standard warranty is a pretty basic 3yrs/36,000 miles.
