In keeping with the most stringing quality standards, Mazda developed a new painting method dubbed the "Hi-Reflex" system for the Millenia.  The car was rotated as it was painted and dried with several layers.  This virtually eliminated the "orange peel" traditionally found on the vertical surfaces of cars while producing a highly durable paint surface.  This unique process also led to amazing depth and clarity in the paint - almost as if you could dip your finger into it!

Thorough wind testing and computer modeling were performed in order to achieve the amazingly low 0.29 coefficient of aerodynamic drag (same as Mazda's RX-7).  This result was exemplary in 1994 when the car was introduced, and it still is today.  Most sedans have a coefficient of drag around 0.32.  This helps the Millenia slice through the air and maintain stability at higher speeds while achieving up to 28 mpg on the freeway.
