Lexus is Toyota's luxury vehicle division established in 1989. Toyota conducted extensive market research in the US and concluded a separate luxury brand was needed. After a development process involving over 1400 engineers and $1 billion, the Lexus LS 400 was unveiled in 1989 and aimed to expand Toyota's product line upwards. Lexus has since grown to be sold globally and aims to grow 10% annually, especially in emerging markets like China and Vietnam while maintaining growth in its largest market, the US. Lexus differentiates itself from competitors through its vehicles' quality and technology to attract buyers in the luxury segment.
