Lexus is the luxury car division of Japanese Import Car maker, Toyota Motor Corporation. The first Lexus was introduced in the United States in 1989. Lexus is now sold globally and has become Japan's largest selling make of luxury cars. Lexus is headquartered in Toyota, Aichi, Japan.

The Lexus LS was the flagship sedan project that began in 1983. The sedan was launched in 1989. Lexus added sedan, coupe, convertible and SUV models in later years. A hybrid version of the RX crossover debuted in 2005. Additional hybrid models were soon added to the Lexus lineup. In 2007, Lexus launched its performance division with the IS F sport sedan.

Lexus cars have  incorporated touchscreen navigation system interfaces, a smart key entry and startup system, SmartAccess, and  Optitron gauges. In 1989, Lexus became among the first luxury line to equip models with premium audio systems, in partnership with stereo firm Nakamichi. Optional surround sound systems are offered via high-end audio purveyor Mark Levinson. In 2006, the LS 460 climate control system included  the first ceiling air diffusers and infrared body temperature sensors in a car.

In 2006, Lexus incorporated the first eight-speed automatic transmission in an automobile with the LS 460. The gearbox was later adapted for the GS 460 and IS F models. Continuously variable transmissions, regenerative braking, and electric motors have been used on all Lexus hybrid models. Lexus executives in 2007 signaled intentions to equip further models with hybrid powertrains.

Safety features on Lexus cars include stability systems, backup cameras, swivel headlights, and sonar warning systems. The Lexus Pre-Collision System (PCS) integrates multiple safety systems. The first car safety systems with infrared and pedestrian detection capabilities, lane keep assist, a Driver Monitoring System with facial recognition monitoring of driver attentiveness, and rear pre-collision whiplash protection, were introduced by Lexus as part of the LS 460 PCS in 2007.
