The Lexus RX is a mi-size a crossover SUV produced by Toyota Motor Corporation. In North America, Europe, Oceania, and parts of Asia, including Singapore as a 2003 introduction and Japan as a 2008 introduction, it is sold by Lexus, Toyota's luxury division, as the Lexus RX series (such as the RX 300, RX 330 and RX 350). It is currently sold in Japan and previously in Singapore as the Toyota Harrier (until the RX introduced its second generation). The RX first premiered in 1997 as a Lexus concept, followed several months later by debut of the production RX 300/Harrier models. In 2003, the second generation RX debuted in the U.S., and the redesigned RX 330/Harrier went on sale shortly after. In 2004, the RX line added the world's first luxury-type hybrid, the RX 400h, and the RX 330 was upgraded to the RX 350 for model year 2007.
