September 2006
 Filed under: LEXUS Car News | LEXUS Headlines
September 12, 2006 – Torrance, CA - Lexus integrates advanced technology in all its vehicles, with a focus on ease of use, more comfort, and more driving pleasure. The brand's reputation for quality applies to every vehicle feature and system, and any technology that the customer contacts must be easy to understand and use.
Following is a review of some of the advanced technology featured in 2007 Lexus models that enhances performance, comfort and convenience.

Performance

Engines That Think Big
All Lexus engines employ continuously Variable Valve Timing with intelligence (VVT-i), which eliminates the compromise between low-end torque and high-rpm horsepower by optimizing valve overlap throughout the engine's speed range, not just at one or two set speeds. The new-generation V6 engines in the Lexus ES 350, RX 350, GS 350 and IS models employ a new Dual VVT-i system that acts on the exhaust valves as well as the intake valves.

The 3.5-liter V6 in the GS 350 and IS 350 models augments port fuel injection with a direct-to-cylinder fuel injection system. The direct injection provides a cooling effect in the cylinders, allowing the higher compression ratio that results in greater efficiency and power and enhanced drivability. All Lexus models are certified as Ultra Low Emissions Vehicles or better (ULEV, ULEV II or SULEV).

Road-Sensing Throttle Control
Seeking to enhance driving smoothness at every level, Lexus equips the SC 430 model with Intuitive Powertrain Control. Working with the electronic throttle control, this system helps to smooth out acceleration from a standing start by very slightly delaying the throttle opening when the driver steps on the accelerator.

All-Wheel Drive Passenger Cars
The 2007 GS 350 and IS 250 models offer all-wheel-drive as an option. A planetary-gear center differential and a wet-type multi-disc clutch control front/rear power distribution. The system normally sends 70 percent of the power to the rear wheels to provide the traditional performance advantages of a rear-drive vehicle, but will vary the torque split ratio from 30:70 to 50:50 in response to driving conditions and driver input. The system's electronic control strategy takes inputs from steering and throttle angle, combined with vehicle signals from wheel speed and yaw rate sensors.

Vehicle Dynamics Integrated Management
The 2007 LS 460 and 460 L, GS 430, GS 450h, IS 350 and RX 400h models feature the advanced Lexus Vehicle Dynamics Integrated Management (VDIM) system. VDIM integrates and manages a host of handling technologies more quickly than other dynamic handling technologies can.

In the LS 460 and 460 L, RX 400h, GS 430 and GS 450h models, an important component of VDIM is the Electronically Controlled Brakes (ECB), a "brake-by-wire" system. ECB translates brake pedal pressure into electric signals that, via computer control, help provide precise and optimized braking in virtually any traction condition. Electronic control provides quick brake response when needed, helping the VDIM system to anticipate and help correct slides before they might occur. The ECB system is backed by conventional hydraulic brake control in case of the unlikely event of electronic failure.

VDIM integration strategy provides precise control for the ECB, Electric Power Steering (EPS), Vehicle Stability Control (VSC), ABS, Brake Assist (BA), Electronic Brakeforce Distribution (EBD) and engine torque via the electronically controlled throttle. On the LS 460 L, GS 430 and GS 450h models, VDIM also influences Variable Gear Ratio Steering (VGRS) to affect minor steering corrections when needed.

Electric Power Steering
Electric Power Steering (EPS) in VDIM-equipped Lexus models provides precise electric power assist using a DC motor built into the steering gear housing, rather than traditional hydraulic assist. Eliminating the hydraulic steering pump reduces engine drag, and the simplified steering system is lighter and more compact than hydraulic power steering systems.

The VGRS system in the LS 460 L, GS 430 and GS 450h models is a further development of the technology featured on the Lexus LX 470 luxury utility vehicle. VGRS electronically adjusts the steering ratio according to vehicle speed. In the LS 460 L,GS 430 and GS 450h, VGRS can vary the steering from 2.7 turns lock-to-lock for low-speed maneuverability to a slower 3.2 turns lock-to-lock for highway-speed stability. (By comparison, the GS 350's hydraulic power steering system uses a constant 3.2 turns lock-to-lock.) Additionally, VGRS provides differential steering control, which helps correct for a delay in steering response, something that occurs in all vehicles. This function helps enhance driving feel in lane changes and other transitional maneuvers.

Adaptive Variable Suspension
The Adaptable Variable Suspension (AVS) system is standard on the LS 460 L, GS 430 and GS 450h sedans and the GX 470 and LX 470 luxury utility vehicles. Responding to road conditions, driver input and vehicle speed, AVS continuously adjusts the shock absorber damping force to help provide the best balance of ride comfort and handling response. For the GX and LX, the driver can select from normal, comfort and sport settings; for LS 460 L, GS 430 and GS 450h, there are two selections: normal and sport.

Comfort and Convenience

Active-Control Engine Mount
In the ES 350 sedan and the RX luxury utility vehicles, an active engine mount helps keep even the smallest vibrations from reaching the passenger compartment. A solenoid-controlled diaphragm produces pulses equal-to-but-opposite those of the engine, helping to dampen vibration with every power stroke.

Rear Back-Up Camera
All 2007 Lexus models offer a rear back-up camera that provides an extra measure of confidence when reversing the vehicle. The rear back-up camera is standard in the LX 470 luxury utility vehicle, LS 460 L, and the GS 450h hybrid sedan. In all other models, it is part of the available navigation system. The camera gives the driver a view of what its lens can detect behind the vehicle, projecting a color image onto the central display screen when reverse gear is engaged.

Dynamic Laser Cruise Control
The RX 350 and RX 400h models offer available Dynamic Laser Cruise Control This system uses lasers to collect data from scanning points ahead and is designed to help the driver automatically maintain a set distance from the vehicle traveling in front.

Dynamic Radar Cruise Control
All new-generation Lexus sedans offer the Pre-Collision System (PCS), which integrates the Dynamic Radar Cruise Control system. In place of laser beams, as used in the Dynamic Laser Cruise Control system, a millimeter-wave radar system is designed to detect vehicles traveling ahead.

Intelligent Climate Control
All Lexus models come equipped with automatic climate control. The system in the LS 460 features temperature- and sun-sensing intelligent swinging registers. If sunlight is concentrated on one side of the car, the registers will automatically deliver more cooling air to that side. Seatbelt buckle sensors indicate the presence of passengers, and the system directs air accordingly.

The SC 430 hardtop convertible's climate control system adjusts airflow and temperature automatically, differentiating between top-up and top-down driving needs. For example, when driving in cooler weather with the top down, the system will direct warm air to the feet and lap areas. On warmer days, the system will circulate cool air to the same locations. The LS 460 offers a rear air conditioning system that supplements the standard cabin air filter with an optical deodorizer. The unit uses a catalyst-coated filter and an ultraviolet light to help break down odor-causing elements.

Power Rear Door
The LS 460 L luxury sedan, and the RX 350 and RX 400h luxury utility vehicles feature a standard power rear liftgate that can be activated either from inside the vehicle or by the in-key remote. Remote operation can be programmed for one-click opening. In addition, pushing a button located on the bottom edge of the door can close the liftgate. Touch sensors on the door are designed to detect obstacles and can stop the door from opening or closing. As an added precaution, a warning sounds when the door is opening or closing to alert people standing nearby.


Entertainment, Navigation and Security

XM Satellite Radio
An XM Satellite Radio system, which provides CD-quality sound and a wide selection of music and news/talk stations coast to coast, is available in most 2007 Lexus models. XM Satellite Radio helps ensure that the owner's preferred stations remain available continuously, eliminating the need to search for new stations when driving long distances. About half of the available stations broadcast without commercials. The audio system display can show the current song and artist.

DVD Navigation System
Lexus offers a DVD-based navigation system in all models for 2007 (standard in LX 470 and SC 430) except the LS sedans which feature HDD. In all DVD applications, a single DVD holds all of the map data for the contiguous United States and select areas in Canada. All Lexus navigation systems feature voice recognition.

The Lexus fifth-generation navigation system available in most models offers enhanced usability, particularly through the voice-recognition technology. Voice recognition allows the driver to input the destination by voice command, even while driving. The upgraded voice-recognition technology also allows the user to select the nearest point of interest (POI) as the destination.

The fifth-generation Lexus navigation system still incorporates features from previous systems that help make finding destinations easier. One such feature, building footprint display for several major cities, can provide a graphic representation of the buildings near the selected destination or along a route to help the driver identify surroundings. The system also shares the phone number-based business address location feature from other Lexus navigation systems.

The newest navigation system offers Spanish for the voice prompt feature, along with English and French. The user can select language preference at system start-up. All Lexus navigation systems use a high-speed computer that offers quick route calculation (an average of five seconds) and fast map scrolling.

Convenience features include multi-route calculation, route preview, simplified highway junction graphics and a dual-map screen mode. The Freeway Lane Guidance feature will alert the driver to the best lane for an upcoming exit. Additional functions of the navigation system vary by vehicle.

Bluetooth® wireless technology integrates with the navigation system to allow the transfer of personal phone books. The driver can make hands-free phone calls via its touch-screen control panel. Customers can place a handset-free call by either using the keypad on the navigation system to dial a number, selecting their handset phonebook stored in one of two phonebook settings, selecting a point of interest or by using the one-touch dial feature. To help reduce driver distraction, the one-touch dial feature is the only dialing function that a customer can access when the vehicle is in operation. The customer can also use controls on the steering wheel to answer and end calls as well as to adjust call volume.

Anti-Theft System
Lexus equips all its 2007 models with an advanced remote keyless entry and a security system with immobilizer. Only the correct key will start a Lexus vehicle. For convenience, Lexus integrated the remote lock/unlock unit into the key so there is no separate, bulky remote unit to crowd the customer's pocket or purse.

SmartAccess
Standard in the new-generation LS, ES 350, GS and IS sedans, SmartAccess allows the driver to unlock the car simply by pulling on the door handle (with the remote control carried in pocket or purse) and then start the vehicle at the touch of a button or twist of a knob. The SmartAccess key fob, carried in the driver's pocket, transmits a radio signal to onboard antennas, authorizing the security system to unlock the car and permit engine start. The system includes a SmartAccess key wallet card that allows the driver to unlock and start the car if the main key fob is lost.

Mark Levinson® Audio
Lexus is the only automaker to offer an OEM mobile audio system by Mark Levinson. Audiophiles have recognized the Mark Levinson brand as a leader in high-end home audio components since the early 1970s.

Mark Levinson Premium Audio is standard in the SC 430 and LX 470 and is available in all other Lexus models in conjunction with the optional navigation system. The Mark Levinson systems feature discrete amplifier design with ultra-low crossover distortion. All occupants enjoy optimal sound quality no matter where they are sitting.

The new-generation ES 350, IS and GS models offer a new Mark Levinson Premium Surround Sound audio system featuring a maximum of 300 watts of power for ES and IS and 330 watts on the GS's system. These models feature 14 speakers (including a center speaker and subwoofer) and 7.1-channel speaker architecture. Specifications vary by model. In the LX 470 and the ES 350, GS and IS sedans equipped with Mark Levinson audio systems, the display screen provides an in-car theater. With the transmission in Park and the parking brake set, passengers can view a DVD movie on the navigation screen.

The new LS 460 and LS 460 L offers a specially developed 19-speaker, 450-watt, discrete 5.1 Mark Levinson® Reference Surround sound audio system, creating a new benchmark for automotive sound systems with its theater-level entertainment experience.

Rear-Seat Entertainment
All Lexus SUVs offer an optional rear-seat DVD entertainment system, which plays movies on an LCD screen that deploys from the headliner in front of the second-row seats. Two sets of wireless headphones and a remote control are included with the option. For 2007, the system in the RX and GX models has been upgraded with a larger 9-inch wide-format screen.


All-Road/Off-Road Travel

Adjustable Suspension
The LS premium luxury sedans and the RX 350 luxury utility vehicle offer an optional air suspension system designed to enhance handling, driving comfort and versatility. Automatic load leveling helps to ensure generous suspension travel and preserve ride comfort. Four driver-selectable height settings allow the driver to tailor the RX 350 to specific driving conditions or needs.

The GX 470 features Rear Air Suspension for increased ride comfort over various road surfaces. In addition, the Rear Adjustable Height Control (RAHC) is included to lower the rear by 1.2 inches or raise it by 1.6 inches for easier loading and unloading.

The LX 470's standard hydraulic Adjustable Height Control (AHC) allows the driver to raise the vehicle to help handle rough off-road terrain and to lower it for easy entry and exit. A height-control switch and light indicate current suspension height and the light flashes when height changes occur.

For off-road travel, switching to high increases the angle of approach from 30 to 32 degrees and the angle of departure from 23 to 26 degrees to help the vehicle negotiate obstacles.

The LX 470 will go into extra high mode if it is in low range and traveling over rough terrain, with the height rising automatically by 1.2 inches at the front and approximately 1.8 inches in the rear.

If set in high mode, the suspension will automatically lower when the LX 470 exceeds 18.6 mph, a more than adequate speed for rigorous off-road conditions.

Kinetic Dynamic Suspension System (KDSS)
The GX 470's available Kinetic Dynamic Suspension System (KDSS) enhances the vehicle's on-road ride and handling and off-highway capability. Electronically controlled hydraulic cylinders help vary the degree of sway resistance provided by the front and rear stabilizer bars. KDSS helps provide more sway stiffness when needed for crisp handling response and less sway resistance to ensure comfort and traction over uneven road surfaces.

The GX 470 also features two systems to help control the vehicle in rugged driving conditions. Downhill Assist Control (DAC) augments the low-speed descending ability in low range by helping to hold the vehicle to a comfortably low target speed with no intervention from the driver. The Hill-start Assist Control (HAC) system helps provide additional control when starting up an incline by gently applying the brakes if the vehicle starts to roll backward.
