In 1993 the Mazda626 saw big changes in body style and powerplants since the 626 moved to an entirely different platform, moving it to the mid-size class, the same time Nissan launched the mid-sized Altima (replacing the Stanza compact car) to compete with the redesigned 626.
Mazda's new 4-cylinder is a much-improved 2.3 L 4 with 160 hp (119 kW); the V6 is a 3.0 L, 220 hp unit based on Ford's Duratec engine block, but with completely reworked cylinders and valvetrain components.
Mazda was the last of the Japanese to increase its entry to "midsize" status; the 6 is still the smallest (and most agile) of the bunch.
