Lexus LS430 Interior Review
Slip into one of the cushioned seats of the LS 430, and relax in one of the most luxurious environments in the automotive world. At the same time, the padded and protected passenger compartment is a sophisticated space, overflowing with high-tech gear and power-motivated gadgets to make the driving experience safe, comfortable, even sensuous and pleasurable.
There's ample space for heads and legs and elbows, and enough room in the rear seat to cross even long legs without touching the front seatback. The three-person rear bench has contoured spaces for two and a broad center fold-down armrest. The armrest features a padded storage drawer and a panel to control the heated seats, compact disc player and rear climate system. Extensive applications of leather and rich wood set an opulent mood.
The driver faces an adjustable steering wheel trimmed in wood and leather, mounted in front of a new instrument panel with vivid electroluminescent analog gauges that are among the best available. To the right and immediately above the console, a seven-inch touch screen incorporates controls for climate and audio, as well as the optional navigation system. All variables and instructions show up on the screen as bold and legible icons that simplify operations; you can also use voice commands to direct the action.
Again and again, the Lexus uses complex computer technology to simplify the driving experience. The automatic climate system, for example, reads temperature sensors around the cabin, and sun-sensing articulated air registers deploy in particular areas as needed to combat a solar heating.
Extensive safety measures begin with the strong structure, incorporating impact-absorbing crumple zones and steel reinforcements surrounding the passenger compartment. Seat-mounted side airbags help augment the required front-mounted bags to shield front-seat riders. Side-curtain airbags are mounted above the side windows, front and rear. High Intensity Discharge (HID) headlamps, rain-sensing windshield wipers and front side window glass that repels water enhance driver visibility.
Active safety controls include anti-lock brakes, which automatically apply extra braking force during emergency stops. An advanced vehicle skid control (VSC) system weds ABS and traction controllers with microprocessors to correct oversteer or understeer. These systems help the driver to maintain control of the LS 430 in emergency maneuvers even when he or she panics and makes mistakes.
Lexus LS430 Road Test
The Lexus LS 430 delivers excellent throttle response and impressive handling for a vehicle of its size and weight. Quick acceleration gives the LS 430 a lively feel. Yet it rides so smoothly and quietly that triple-digit speeds feel sedate, as we found at the 4.0-mile Road America road-racing circuit at Elkhart Lake, Wisconsin.
The 4.3-liter engine generates 290 horsepower and, more importantly, 320 foot-pounds of torque. That's enough to propel the big Lexus from 0 to 60 mph in about 6.7 seconds, according to Car and Driver magazine, and past the quarter-mile mark in about 15.3 seconds. That is quite quick. That means the Lexus LS 430 leaves the Acura RL in the dust. It's not as quick as a BMW 540i, Mercedes E430, or Jaguar S-Type 4.0, however. Top speed of the LS 430 is electronically limited at 131 mph.
Lexus builds one of the quietest cars available. The LS 430's engine is barely audible. Mechanical and road vibration is damped out as well. No other automaker does a better job than Lexus in creating such a serene and rattle-free zone for riders.
Technology helps ensure the driver keeps the LS 430 on the road in an emergency handling situation. Its Intuitive Powertrain Control module analyzes throttle position, vehicle speed and engine load before allocating torque to the rear wheels.
With power directed to the rear wheels and independent suspension all around, the LS 430 provides a classic chassis layout for driver control. Anti-lift and anti-squat suspension geometry reduces body pitch when accelerating or braking. Lateral roll, or body lean, is held to a minimum in hard corners. The Ultra Luxury Package includes adaptive suspension damping to further isolate the passenger compartment from uncertain road conditions.
A no-cost optional Euro-style touring suspension brings firmer shock settings for more sporting manners.
Another high-tech option puts a laser to work with the cruise control to maintain a pre-set distance between the Lexus and the vehicle in front of it. The smart system removes the last vestige of work associated with automatic cruise control, because it can detect a vehicle ahead and modulate speed to maintain a safe distance.
Lexus LS430 Lineup
The LS 430 retails for $54,405. That figure buys a premium, full-size sedan loaded with sophisticated mechanical equipment, extensive safety systems and luxurious appointments. The sole engine, a four-cam 4.3-liter aluminum V8, produces 290 horsepower and mates to an electronically controlled five-speed automatic transmission.
Opt for the aptly named Ultra Luxury Selection ($12,485) and the factory adds a list of hardware that reads like science fiction: laser-guided cruise control, a sonar-based parking guide, a navigation system that triangulates by satellites and coordinates with a DVD-powered data base, and an adaptive electronically controlled suspension that rides on air rather than springs. A fan inside the front seats circulates either heated or chilled air. Rear-seat passengers relax with their own air conditioning and air filtration system; plus heated seats, with electric seatback adjustment, memory control and a power lumbar massager. A power-operated sunscreen shades the backs of rear passenger's necks. Side-window screens are provided, but must be pulled down manually.
