The Sentia was marketed by Mazda as having a "front midship" layout: the V6 engine sits behind the front axle, while the fuel tank rests above the rear axle. This iteration of the Sentia also debuted Mazda's speed-sensitive four-wheel steering system. At speeds of lower than 35kph, the rear wheels steer in an opposite (toe out) direction from the front wheels, in order to reduce the turn radius. At higher speeds they steer in the toe in direction to improve stability.
Solar ventilation system is a setup where amorphous solar cells in the sunroof panel powers small ventilation fans located in the trunk area, in order to cool the cabin while the car's parked in the sun. This setup would later be found on the Eunos800/Millenia.
There are two engines available. Both have their roots in prior Mazda V6s, and have no relation to the aluminum KL series found in the 626-platformed Mazdas. The 3-liter JE-ZE receives a new variable intake manifold to boost its power rating to 200PS. The 2.5-liter J5-DE is also available, rated at 160PS.
