The LS 600h L Hybrid: The Ultimate Lexus
Lexus Press Release
3 September 2008
The Lexus LS 600h L luxury sedan was the first vehicle to bring fuel-efficient gasoline-electric hybrid technology to the prestige luxury segment. The LS 600h L provides the brand’s highest level of performance and technology, and the truest expression of luxury.
Engine, Transmission, Drivetrain and Performance
The LS 600h L is powered by the ultra-quiet Lexus Hybrid Drive system, which was the world’s first to combine a V8 gasoline engine with an all-wheel-drive (AWD) hybrid drivetrain. The system combines a 5.0-litre V8 gasoline engine with two powerful electric motors and a large-capacity battery pack.
The hybrid powertrain generates a peak combined output rating of 438 horsepower and can effortlessly accelerate the LS 600h L from zero-to-60 mph in just 5.5 seconds. Mid-range acceleration is even more impressive. The system’s electric motor is capable of delivering maximum torque on demand and is most beneficial during passing manoeuvres. The LS 600h L can accelerate from 50-70 mph in a rapid 3.5 seconds. Its combined EPA fuel economy rating of 21 mpg is equal to or better than the combined fuel-economy ratings of some V6 all-wheel-drive mid-sized luxury sedans.
The innovative V8 features an electric motor-driven Variable Valve Timing with intelligence and Electrically controlled intake cam (VVT-iE). This combination of VVT-i with electric-motor driven intake and an oil controlled VVT-I exhaust system achieves superior engine-startup operation and high-output performance. A specially developed Hydrocarbon Adsorber and Catalyst (HCAC) system is linked to the two-way exhaust to help prevent hydrocarbons contained in the exhaust from being released into the atmosphere during cold start up when the catalysts are not up to temperature.
The LS 600h L meets the Super Ultra Low Emission Vehicle II (SULEV II) certification, meaning it has nearly 70 percent fewer smog-forming emissions than vehicles the average new car. Its emissions are cleaner than the ambient air in some major cities.
The NVH levels in the LS 600h L make it one of the quietest automobiles ever built. The LS 600h L is a full hybrid, capable of operating in electric-only mode or with a combination of the gas engine and electric motor. Lexus hybrid technology allows electric-mode-only operation at low speeds or stop-and-go driving conditions, reducing fuel consumption and noise.
A 288-volt DC Nickel Metal Hydride (Ni-MH) compact battery pack is installed behind the rear seat. The trunk also contains a 12-volt auxiliary battery that powers the audio, navigation, and other systems. The battery’s power is directed through a “boost converter” that efficiently raises voltage to a maximum 650V DC. An inverter changes this to AC, providing its elevated power to a 165-kW electric motor that turns at up to 10,240 rpm.
The LS 600h L powertrain uses two motor generators: MG1 and MG2. Each performs specific functions and can operate as either a motor or a generator, although MG1 is used as a starter motor and provides no motive force. The engine-driven generator, MG1, can charge the battery pack or provide additional power to the drive motor, MG2, as needed. A regenerative-braking system further boosts efficiency. When the vehicle is coasting or the brakes are applied, the electric motors function as generators, capturing kinetic energy that would normally be lost as heat through the brakes and transforming it into useable electricity to recharge the batteries.
A state-of-the-art full-time all-wheel drive system adapts to road surface conditions to help provide excellent vehicle stability during acceleration, high-speed driving and cornering. The AWD system employs a compact, ultra-quiet transfer case equipped with a TORSEN limited-slip differential (LSD) that is 30 percent lighter in size and weight than previous TORSEN systems. The LSD provides rear biased torque distribution of 40:60 under normal straight-line driving, automatically and continually adjusting power distribution according to changing speed and road conditions.
An eight-speed sequential braking mode, activated when the shift lever is in the “S” position, allows eight different stages of response. When up-shifting, engine speed is controlled by the selected range, offering an exhilarating boost in acceleration during each of the eight shift stages. When downshifting, brake-force increases to provide powerful deceleration.
The driver can select “hybrid” (normal), “power,” or “snow” options. The “hybrid” mode provides the smoothest operation and is ideal for city or suburban driving; “power” sharpens accelerator pedal response and “snow” mode softens accelerator pedal response, making it easier to accelerate on slippery road surfaces. By pushing an EV switch, power reverts to full electric mode for short-distance, slow driving situations such as residential areas or parking garages.
Chassis, Body, Suspension, Tyres and Brakes
Multi-link front and rear air-suspension systems help maintain superb vehicle posture and stable driving performance while maintaining the ultra-comfortable ride that has become synonymous with all Lexus vehicles. An Active Power Stabiliser Package is also available and features 19-inch summer tyres, and high-friction brakes and an active-stabiliser system to help reduce body roll.
The LS 600h L is equipped with large front- and rear-ventilated disc brakes and standard 19-inch, seven-spoke aluminium alloy wheels with all-season tyres. These special wheels receive extensive buffing, and their shape is meticulously analysed to create a form with shade depths that shift when the vehicle is in motion.
Electronic Power Steering (EPS) delivers a smooth steering feel and reduces parasitic losses to the engine. Variable Gear Ratio Steering (VGRS) optimises the steering gear ratio according to vehicle speed, enhancing responsiveness and driver control. Integrated with the Vehicle Dynamics Integrated Management (VDIM) system, VGRS can make minor adjustments to the front-wheel angle to help provide improved stability in challenging road conditions.
Safety and Security Features
The Vehicle Dynamics Integrated Management (VDIM) stability system assimilates and manages all of the car’s dynamic handling sub-systems, including: the Electronically Controlled Brake (ECB) system, EPS, Vehicle Stability Control (VSC), Antilock Braking System (ABS), Electronic Brake-force Distribution (EBD) and engine torque via the electronically controlled throttle. Monitoring a variety of sensors, the system anticipates the onset of a vehicle skid or slide while cornering, and then helps correct the situation with a combination of braking, throttle and steering control in a way that is essentially transparent to the driver. VSC can be turned off by experienced drivers via the Trac Off button.
In addition to the active safety features, the LS 600h L is standard-equipped with eight standard airbags, with a maximum of 11 airbags available through option packages. The world’s first low-beam LED headlamps provide superior road illumination, and the standard Adaptive Front lighting System (AFS) helps to illuminate a turn or curve as the driver steers into it.
The Advanced Pre-Collision System (APCS) on the Pebble Beach Edition LS 600h L is the world’s first system designed to help detect pedestrians in the vehicle’s path. Using two small cameras mounted at the front of the car that work in conjunction with millimetre-wave radar, APCS is sensitive enough to detect certain nonmetallic objects.
As part of APCS the LS also offers the world’s first Driver Monitor System. A third camera, mounted on the steering column, monitors the orientation of the driver’s face. If the camera detects that it appears the driver is not looking directly ahead for a few seconds or more, and if an obstacle is detected ahead, then it alerts the driver first with a warning chime and a flashing light. As the car gets closer to the obstacle, APCS can begin to gently apply the brakes on its own. To assist the driver in manoeuvring around the obstacle, the system reprograms the steering ratio, amplifying the intensity and quickness of the steering response. At the same time, the system automatically retracts the front seatbelts and prepares the brake system to respond with full force when activated by the driver in anticipation of a possible impact.
Luxury, Comfort and Convenience
The LS600h L is based on the long-wheelbase LS chassis, delivering nearly five inches more legroom than the standard LS 460. This flagship model provides the highest level of comfort and convenience features in the LS series. Standard features include a hard disk drive (HDD) Lexus Navigation system with a backup camera and Bluetooth technology with voice activation, plus XM factory-installed satellite radio with real-time traffic displays and dynamic route guidance.
For theater-level entertainment, the LS 600h L features a standard 19-speaker 450-watt Mark Levinson Reference Surround Sound audio system. A portion of the HDD is dedicated to storing as many as 2,000 (128-bit) digital songs. An auxiliary jack located in the front center console allows for iPod or MP3 digital music players.
Additional standard features include a climate-controlled front seats, heated rear seats, a heated steering wheel, power rear sunshade, one-touch open/close power trunk, power door closers, headlamp washers, SmartAccess with push-button start and card key, electronic parking brake, Intuitive Park Assist, and laminated side glass.
The optional Advanced Parking Guidance System (APGS) is designed to assist with parallel and back-in parking. Once the driver has correctly positioned the car and identified the desired parking spot via the navigation screen, APGS utilises the rear back-up camera parking sonar sensors and electric power steering system to guide the car into the space, while the driver controls speed via braking.
The Premium Package includes climate comfort rear seats with a heat/cool knob, rear power seats with memory, rear power headrests, rear seat side airbags, Lexus Link and APGS. The rear power seats have a built-in 28-degree angle and recline up to 38 degrees; the rear seat moves front to back approximately three inches.
The Premium Package II includes all features in the Premium Package and a heater control panel, four-zone climate control, rear audio controls, additional wood trim, rear air purifier, rear cool box, rear headliner and side air ducts, power rear-door sunshades, and a rear seat entertainment system equipped with a power ceiling-mounted nine-inch screen for DVD viewing.
The Executive Class Seating Package II includes all features in the Premium Package II and includes a power right rear seat with ottoman that reclines up to 45 degrees with an upper-back recliner featuring a 17-degree angle adjustment. A multi-function massage feature for the right-rear seat recliner can be used separately or in conjunction with the seat heater and cooler.
The package also includes a rear-seat wood-trimmed table and the rear-seat entertainment system features wireless headphones. The rear climate control is upgraded with an infrared sensor located in the headliner that measures lap, upper body and seat surface temperatures on each side and then adjusts airflow accordingly.
The LS 600h L flagship hybrid luxury sedan showcases the brand’s L-finesse design philosophy, revealing a family resemblance that conveys elegance, refinement and a strong emotional appeal. Minimal body gaps, a low front grille and deep-drawn fenders all contribute to the car’s distinctive, muscular profile. Lexus’ attention to detail is seen in the integrated dual chrome exhaust tips and the one-piece chrome window surround.
Projector-type headlamps with blue crystal rings, which introduced the world’s first night-time LED low beams, provide excellent visibility and contribute to the design theme. Blue accents on the front headlamps, taillamps, badging, engine cover and the SmartAccess key fobs and Smart Card key are unique to the LS 600h L.
Passenger space and comfort were the primary focus of the interior cabin design. Genuine semi-aniline leather is featured throughout the cabin, its rich appearance softened and structured with additional stitching to create a relaxed atmosphere. The leather-trim extends beyond the seats and onto the instrument panel, upper front doors and door armrests. An Alcantara headliner adds a pleasing touch point, and the center console adds to passenger comfort and convenience through perfect angle placement for ease of use from either the driver or front passenger seat; it is placed at the same height as the door armrests for a comfortable balance. Additional luxury touches unique to the LS 600h L includes a wood-trimmed and chrome-plated shift knob and wood-trimmed assist grips.
