Mazda has begun production of its new generation I4 engine series. The new engines, which were jointly developed with Ford, feature all-aluminum construction and will be offered in 1.8-, 2.0-, and 2.3-L versions. The engines will first appear in the Mazda 6/Atenza sedans and some Ford models. Ford expects to need about 2,000,000 of the new engines over the next few years, which will also be built in Ford plants in the U.S., Mexico, and Spain. Mazda will produce 425,000 of the engines. Production of the Atenza sedan begins later this month for Europe. The Mazda 6, which will replace the 626 in the U.S. market, will be launched in the fall of this year and will appear in showrooms in 2003.
