The only change Mazda made to its lineup of Millennia sedans for 1998 was to discontinue the L Sedan. That left only two versions of the Millennia available to buyers -- the Base sedan and the higher-end S sedan. The Base Millennia was powered by a 170-horsepower 2.5-liter V6, and came with such standard features as a four-speed automatic transmission, air conditioning, power windows, power door locks, a tilt steering wheel with a memory feature, cruise control, automatic climate control, dual airbags, and a lighted entry system. The S version received a supercharged 2.3-liter V6, which pushed horsepower up to 210. It was equipped with an upgraded list of standard features that included leather seats, a power sunroof, and traction control. Generally, drivers were very positive about the Millennia sedan, praising it for its quiet engine, smooth handling, luxury features, and good value, especially when compared to other luxury automobiles. On the downside, some noted that power was adequate but not spectacular, and that gas mileage was not as good as expected.
