Toyota's purpose in creating the Lexus brand was to advance into the luxury market, which had long been a bastion of European manufacturers including Mercedes-Benz and BMW. The Lexus LS 400 was announced in January 1989 at the Detroit Motor Show, and was placed on the market in September in North America. The Japanese version of the LS 400, named the Celsior, was positioned as the top-grade sedan for private customers in Japan and was released in October 1989.

The Celsior/Lexus LS 400 came in three model grades (A to C), featuring different sets of equipment and accessories. Developed completely from scratch, the Celsior/Lexus LS 400 achieved the highest level of driving performance and comfort. Most notably, noise and vibrations were significantly reduced at the source, markedly improving ride comfort. The 4,000 cc V8 DOHC 32-valve engine produced an output of 260 PS. The suspension employed a 4-wheel double wishbone design, with coil springs for A and B grades and an electronically controlled air suspension scheme for the high-end C grade. The B grade featured the Piezo TEMS, an electronically controlled suspension that could instantly switch the damper settings from the normal "hard" mode to the "soft" mode in response to the road conditions.

Befitting the top-end sedan, the Lexus LS 400 not only featured superior performance, unusually high specs, and luxurious equipment, but also a superb finish down to the last detail. As a result, it quickly came to enjoy enormous popularity in the U.S. Its uncompromising quality daunted its competitors, setting a new benchmark and deeply affecting the subsequent design of luxury cars throughout the world.

The Celsior won the 1989-1990 Car of the Year Japan.
