‘When the Lexus LS400 was introduced then years ago it created a new luxury car benchmark by which its competitors were judged, says Johan van Zyl, Toyota’s Managing Director Marketing. The opposition may have been caught a little off guard but it did not take long for the competition to fight back and raise the stakes in the luxury car market.

In essence, Lexus, the luxury car division of Toyota Motor Corporation can be credited with promoting a revolution in the world luxury car market to lift it out of a relatively conservative existence. Today Lexus is in the process of once again redefining the benchmarks in the luxury car market with the all new LS430. New in appearance and with notable mechanical improvements the Lexus LS430 represents another leap forward in this exclusive market segment.

Super-Sleek Body Virtually Eliminates Win d Noise

While retaining the flavour of the original and second-generation LS 400s, the new third generation top of the range Lexus exudes a more muscular presence. The sleek exterior offers a lower drag coefficient and exceptional aerodynamics. To prove out the aerodynamics of the LS430, Lexus engineers tested the prototype in the same wind tunnel used in the development of Japan’s legendary bullet trains.

Fine tuning of airflow around bumpers, fenders, and mirrors, and over the floorpan, contributed to the LS 430’s high level of aerodynamic efficiency. Even the angle of the radiator grille bars was fine tuned for optimum aerodynamics. The result, a clean shape that generates virtually no wind noise as it cuts its way through the air, making the LS 430 even quieter inside than its benchmark predecessors.

In addition, the ultra-low Cd helps keep fuel consumption at much the same level as that of the LS400 even though the new LS430 has an increased engine capacity and performance and has a higher profile than the LS400.

To increase interior room in the LS 430, Lexus lengthened the wheelbase by 75mm but kept overall length the same. Compared to the latest arrival in the segment, an externally larger car (Mercedes-Benz S-Class) the LS 430 offers more front leg- and headroom, slightly more cabin volume, and a larger boot.

In building the new LS 430, Lexus used a supercomputer to digitise the precise surface design of the body. The unit of measure used was 1/1000 of a millimetre, ten times more precise than the typical 1/100 of a millimetre unit used by other car companies. The result is more-precisely stamped sheet metal for better fit and assembly quality.

While Lexus has won the J.D. Power and Associates five-year Vehicle Dependability Study in its major market – the United States – every year it has been eligible, the company made what it considers 57 substantial improvements for even greater durability.

In Search of True Luxury

Before designing the LS 430, Lexus designers and engineers studied luxury and craftsmanship outside the automotive realm. They visited luxury hotel rooms, including presidential and royal suites for national guests, and surveyed first class aircraft cabins and luxury jet interiors. They also observed high-end jewellery and watch makers and guitar makers at work.

This all in the search for perfection in imparting a luxury environment and feel to the new LS430.

The LS 430 adds new, higher grades of leather and wood as trim materials. The climate control system features temperature and sun-sensing articulating air registers. If, for example, sunlight is concentrated on one side of the car, the registers will automatically deliver more cooling air to that side.

Additional adjustments for the driver’s seat include dual lumbar controls and adjustable cushion length for greater thigh support.

The standard combination wood/leather steering wheel features controls for the audio system, which includes as standard an in-dash, single-feed six-disc CD changer. The new CD changer location allows for a larger dual glove box, and expanded interior storage includes compartments in the centre console and under the front seats.

High Performance With Ultra-Low Emissions

The original Lexus LS 400 prescribed a V8 engine as the price of entry in the premium luxury segment more than 10 years ago, when European luxury models typically offered less powerful six-cylinder engines. The new 207 kW 4.3-liter V8 in the LS 430, mated to a computer-controlled five-speed automatic transmission, will rocket the Lexus flagship sedan from 0-100 km/h in just over 6 seconds.

Its 417 Nm of torque and enhanced torque curve outclass some larger-displacement engines, thanks in large part to Variable Valve Timing with intelligence (VVT-i). VVT-i eliminates the traditional compromise between low-end torque and high-rpm horsepower by optimizing valve overlap throughout the engine’s speed range. Lexus tuned the LS 430 engine to produce more torque across a broad engine speed range, making the car feel more responsive under all driving conditions.

The LS 430 introduces the industry’s first torque-activated powertrain control, which governs the throttle, based not just on pedal position, but on vehicle speed and engine rpm, as well. When climbing a hill, for example, the controller will increase the throttle opening to provide more power without the driver having to floor it.

The car will behave more smoothly because unwanted up-shifts and down-shifts are avoided, and the driver does not have to keep depressing and releasing the accelerator pedal to maintain a set pace over varying road conditions. Even with the increased performance, the Lexus LS 430 V8 produces very low levels of engine emissions.

Taking Safety To The Next Level

The LS 430 features a strong passenger cell protected by front and rear crumple zone structures. The Supplemental Restraint System in the LS 430 adds advanced variable-force front airbags and side curtain front and rear airbags. Sensors determine the force with which to deploy the front airbags, helping to maximize occupant restraint performance.

The front seats and rear outboard seats feature seatbelt pretensioners with force limiters.

Lexus believes in giving the driver the technology to help avoid danger on the road. The LS 430 includes Brake Assist. Brake Assist interprets a quick, hard push of the brake pedal as emergency braking and, if the driver has not stepped hard enough on the brake pedal to activate the anti-lock brake system, Brake Assist supplements the applied braking pressure.

Vehicle Skid Control (VSC), first introduced by Lexus in 1998 on the LS 400 helps maintain traction control under demanding conditions by detecting and helping to correct for understeer and oversteer. The VSC system integrates traction control to help limit rear wheel spin on slippery surfaces. Both VSC and Brake Assist employ the sensors and actuators of the standard four-channel anti-lock brake system (ABS).

The new Lexus LS430 offers a superb blend of luxury, safety and performance that is set to once again redefine the luxury car segment, says Johan van Zyl. Toyota South Africa is proud to be amongst the select group of Toyota affiliated organisations around the world accredited with marketing and supporting the exclusive Lexus franchise and the flagship LS430.
