Toyota is the biggest seller of hybrid autos on the market. Their Prius is best-selling hybrid car in the wolrd. Now Toyota is introducing two new modified Prius gas-electric hybrids at the 2009 SEMA Show. The Prius Aerius (Latin for "belonging to the air") is a show car  and the Prius Aemulus (meaning "envious imitation") is a drivable close replica of the first one, which has been donated to the Environmental Media Association (EMA) for a charity auction.

The base for Aerius and Aemulus is a third-generation 2010 Prius. Five Axis Design designed custom created a four-piece Aero Kit from polyurethane and recycled carbon materials. The Aero Kit includes a front lip spoiler, side skirts, and a rear lower valance. The result is just amazing - a remarkable 0.25 coefficient of drag.

The custom paint for both vehicles comes from Nippon Color Design Studio America (CDSA).

The car also got side and rear glass on both vehicles receive a Crystalline Automotive Window Film, which blocks up to 99.9 percent of UV light and has a SPF rating equivalent to well over 1,000.

Another feature of Aerius is the audio entertainment system installed in the car. It is provided by Pioneer and maximum output is 900 watts from 10 speakers, which includes two 10-inch subwoofers, 6.75-inch front and 5.25-inch rear component speakers and two Vizualogic 7-inch DVD headrest rear entertainment units.
