The third generation of Mazda's compact sedan had been introduced in 1988. The 4-door (notchback or hatchback) was still called 626, but the related coupe, named MX-6, now rode a shorter wheelbase. For 1990, antilock braking was newly optional on the mid-range 626 LX model, and also on the more costly hatchback GT Touring Sedan. Also new was a fresh grille and new taillamps. DX and LX sedans carried a 110-horsepower, 2.2-liter 4-cylinder engine. A turbocharged rendition of that 2.2-liter was installed in the GT model, developing 145 horsepower.
