Mirroring the predominance of its parent company in the mainstream market, Lexus has become the most successful and biggest-selling of the three Japanese luxury brands in the U.S. Toyota managed to carve Lexus into a marque whose original slogan, "The Relentless Pursuit of Perfection," still provides an ideal and a mission that is both appreciated by and credible to American consumers. When Lexus launched in 1989, the first vehicle was the LS 400 sedan, which importantly shared no major elements with previous Toyota vehicles. It established the brand's continuing reputation for the market's best balance of quiet, ergonomics, engine performance, manufacturing quality and overall value. By 1991, Lexus was the top-selling luxury import in the U.S., and J.D. Power & Associates was ratifying its status with the highest marks in its survey of initial quality. Lexus launched the GS line in 1993. In 1998, Lexus introduced what arguably became its most ground-breaking vehicle: the RX 300 crossover. RX established a sleek styling template and overall platform dimensions and characteristics that would hugely influence generations of competitors. Lexus produced the first production hybrid luxury SUV, the RX 400h, in 2005. Dubiously flush with success, Lexus also launched the hybrid LS 600h recently, at a sticker price of more than $100,000.
