context_page_description: The Lexus LS is a full-size luxury sedan serving as the flagship model of Lexus, the luxury division of Toyota. For the first four generations, all LS models featured V8 engines and were predominantly rear-wheel-drive. In fourth generation, Lexus offered all-wheel-drive, hybrid, and long-wheelbase variants. The fifth generation changed to using a V6 engine with no V8 option, and only one length was offered.
  As the first model developed by Lexus, the LS 400 debuted in January 1989 with the second generation debuting in November 1994. The LS 430 debuted in January 2000 and the LS 460/LS 460 L series in 2006. A domestic-market version of the LS 400 and LS 430, badged as Toyota Celsior, was sold in Japan until the Lexus marque was introduced there in 2006. In 2006, the fourth generation LS 460 debuted the first production eight-speed automatic transmission and an automatic parking system. In 2007, V8 hybrid powertrains were introduced on the LS 600h/LS 600h L sedans.
  Development of the LS began in 1983 as the F1 project, the code name for a secret flagship sedan.
context_section_description: Development on fourth generation LS began in 2001 under program code "250L", with the design process being done under Yo Hiruta from 2002 to late 2003, with the final production design being frozen in 2004. In October 2005, Lexus premiered a gasoline-electric hybrid concept car, the LF-Sh (Lexus Future-Sedan hybrid), at the Tokyo Motor Show, publicly previewing the next Lexus flagship with a concept version for the first time. Introduced at the January 2006 North American International Auto Show for the 2007 model year, the fourth-generation Lexus LS became the first Lexus model to be produced in both standard and long-wheelbase versions. Using an all-new platform, the LS 460 (USF40) uses the standard 2,969 mm (116.9 in) wheelbase, while the LS 460 L (USF41) features a stretched 3,091 mm (121.7 in) wheelbase. The fourth-generation models' technical specifications were shown in greater detail at the Geneva Motor Show in February 2006. A hybrid version, LS 600h L (UVF46), was previewed at the New York International Auto Show in April 2006. At its introduction in 2006, it won the Car of the Year Japan award for the second time.
  The LS 460 and LS 460 L are both equipped with a new 4.6-liter 1UR-FSE V8 producing 283 kW (380 hp) and 498 N⋅m (367 ft⋅lbf) of torque, coupled to the first production eight-speed automatic transmission. Acceleration from 0–100 km/h (62 mph) is listed at 5.7 seconds.
  The development of the LS 460 and its variants, led by chief engineer Moritaka Yoshida, began as Lexus was shifting its design strategy towards a more diversified product lineup, with new-vehicle launches largely focused on global markets. Plans called for the next-generation LS to differentiate itself further beyond previous models in terms of design and technology. A "Super LS" model, priced above the US$100,000 ultra-luxury category, was also considered. Externally, the Lexus LS received the styling cues of Lexus' new design direction, called L-finesse. First shown on the LF-Sh concept, the vehicle gained body forms running the length of the car, wheel arches, arrow-shaped chrome trim, a lower-set grille, and crystalline adaptive headlamps.
  The LS 460 interior gained a push-button start, thin-film transistor instrument display, and numerous luxury options, ranging from a hard disk drive-based GPS navigation system and song library to a heated steering wheel and XM NavTraffic. Standard equipment included power 16-way driver and 12-way front passenger seats with lumbar adjustment and seat heaters, leather upholstery, premium sound system, power moonroof, and trunk pass-through. The climate control offered the first infrared body temperature sensors in an automobile; it also featured ceiling air diffusers. An "Executive" seating package on the LS 460 L included a rear-seat DVD entertainment system, swivel tray table, and a shiatsu massaging ottoman seat.
  It was the first LS with continuous controlled Adaptive Variable Suspension (AVS). The addition of an automated parallel parking assist feature, the first of its kind in the U.S., allowed the LS 460 to steer itself into preselected parking spaces. Other drive-assist features included a brake-hold system, radar cruise control, electric variable gear ratio power steering, and electronically controlled braking. The new stability control system was improved to anticipate skids and alter steering assist and gear ratios. The suite of new safety features extended from an eye-tracking Driver Monitoring System to a lane departure warning system. The pre-collision system added the first production image processing chip in a car capable of identifying vehicles and pedestrians in real time, along with millimeter-wavelength radar, stereo cameras, and infrared night vision projectors. A rear pre-collision system with whiplash-preventing active seat headrests and dual-chamber front airbags was also introduced.
  The LS 460 and LS 460 L arrived at dealerships in Japan, the U.S., and Europe in late 2006, and the vehicle reached Australia, East Asia, and the Middle East in 2007. The U.S. base prices for the
