For 2001, Toyota's luxury division introduced the successor to the 1990-2000 LS 400 sedan, which had been known for hushed accommodations, V8 muscle, and Camry-like dependability. Named for its new 4.3-liter V8, the new second-generation LS 430 sedan offered greater interior space, thanks to a taller roofline and a wheelbase 3 inches longer than its predecessor's. Horsepower remained at 290, but the new LS engine delivered more torque for improved throttle response. A five-speed automatic transmission was used. Rather than continuing the prior one-model lineup, Lexus offered a base model, a base sedan with sport suspension, and an Ultra-Luxury variant. All had side curtain airbags, front lower-body side airbags, high-intensity-discharge headlights, leather upholstery, and an antiskid control system. An available Lexus Line assistance service was provided, in conjunction with the similar GM OnStar system. Antilock four-wheel disc brakes were standard. Sport-suspension versions of the rear-drive four-door got tauter suspension tuning and 17-inch wheels, instead of the usual 16-inchers. Ultra-Luxury models included a dual-mode air suspension, navigation system, Mark Levinson audio system, laminated side glass, power door closers, heated/cooled front seats, and upgraded leather/wood trim with a suede headliner. In addition, the LS featured rear audio and climate controls, a refrigerated armrest, power sunshade, and manual side window shades. Seat adjusters included memory, heat, and massage functions. The LS 430 also offered front and rear parking assistance and laser-operated cruise control, which could maintain a set distance from the vehicle ahead.
Year to Year Changes
2002 Lexus LS: Lexus's flagship sedan got a new lower-priced luxury package for 2002. A firm Euro-tuned suspension was a no-charge option, but required available 17-inch wheels. The new $6895 Custom Luxury Package included a navigation system, heated/cooled front seats, heated rear seats, rear-seat audio controls, and cruise control that automatically maintains a safe following distance. This equipment had been in the $12,505 Ultra Luxury Package, which returned for 2002 at $12,485 and added rear-seat climate controls, massaging rear seats, a self-adjusting air suspension, and Lexus Link service. Both packages required optional upgraded leather upholstery.
2003 Lexus LS: Larger (17-inch) wheels went on all 2003 models, which got some revisions to available features. A firmer Euro-tuned suspension was now a no-charge option. So were all-season tires, to replace the performance treads. The available Custom Luxury Package included a navigation system, heated/cooled rear seats, rear audio controls, and "Smart" cruise control. The Ultra Luxury Group added rear climate controls, massaging seats, a self-adjusting rear suspension, and Lexus Link. Both packages also had heated/cooled front seats and front/rear obstacle-detection systems, each newly available as a separate option.
2004 Lexus LS: Lexus' flagship sedan retains a 4.3-liter V8, but swaps a 5-speed automatic transmission with a 6-speed with manual shift gate. Suspension, steering, and ABS systems are also revised. Driver and front-passenger knee airbags were added as were a tire-pressure monitor, steering-linked headlights, and a power rear sunshade. New options included heated/cooled rear seats, satellite radio, and a rearview camera that uses the navigation system's screen to display a image of the area directly behind the car when backing up. Front and rear styling were also revised slightly.
2005 Lexus LS: An assistance and concierge service is no longer available on Lexus' LS 430 for 2005. A firmer Euro-Tuned Suspension option substitutes 18-inch wheels for the standard 17s. Gone is the optional Lexus Link service, which provided assistance through GM's OnStar network.
2006 Lexus LS: No changes of note for the LS 430 in 2006.
