Amerigon Climate Control Seat(R) System Selected as Option For Front and Rear Seats of Redesigned 2010 Hyundai Equus

Popular Heated and Cooled Seat System Offered in Equus for Korean Market Since 2004 Model Year

NORTHVILLE, Mich., April 29 /PRNewswire-FirstCall/ — Amerigon Incorporated (Nasdaq: ARGN), a leader in developing and marketing products based on advanced thermoelectric (TE) technologies, today announced that its proprietary Climate Control Seat(R) (CCS(R)) system will continue to be offered as an option for the front and rear seats in the redesigned 2010 Hyundai Equus luxury sedan. The Equus, Hyundai’s flagship luxury model sold in Korea, has offered the heating and cooling comfort of CCS as an option since the 2004 model year and was the first luxury sedan in the world to offer the seat system in both front and rear seats. The sedan will be available in showrooms by the end of summer.

The 2010 Hyundai Equus is a technologically advanced luxury sedan equipped with a broad range of standard and optional value enhancing features including CCS, all-leather seats, rich wood trim, a lane departure warning system and many more luxury, comfort and safety enhancing features.

CCS, the premier actively heated and cooled seat system in the global automotive seat market, delivers year-round comfort to automotive seat occupants by providing both active heating and cooling. The system is completely independent of the automobile’s heating and air conditioning system and does not reduce power available to the engine. It also emits no CFCs or other gases and is completely friendly to the environment.

Amerigon President and Chief Executive Officer Daniel R. Coker commented, “Hyundai’s continuing to offer CCS in its next generation Equus, which is its largest and most luxurious sedan, is a strong endorsement of our heated and cooled seat technology. CCS has been well-received in the Korean market and we expect it will continue to play a key role in helping to capture the discriminating Korean buyer in an increasingly competitive automotive market.”

Hyundai also offers CCS in the Hyundai Genesis luxury sport sedan sold in the U.S., Asian and European markets.

About CCS

In the CCS system, which is built around Amerigon’s highly-efficient, solid-state thermoelectric device, air is forced through the heat pump and thermally conditioned in response to electronic switch input from the seat occupant. The conditioned air circulates by a specially designed fan through ducts in the seat cushion and seat back, so that the surface can be heated or cooled. Each seat has individual electronic controls to adjust the level of heating or cooling. CCS substantially improves comfort compared with conventional air conditioners by focusing the cooling directly on the passenger through the seat, rather than waiting until ambient air cools the seat surface behind the passenger.

Amerigon is the largest supplier of TE systems for cars, with more than 4.5 million thermoelectric-based seat systems sold.
