Lexus to release V8 hybrid limousine

Owing to the inherent noise, vibration and harshness (NVH) improvements offered by its hybrid powertrain, the LS 600h L is designed to set a new standard for silent running in the prestige-luxury sedan class. The depth and density of cabin quietness in the LS 600h L required extensive re-engineering of accessory motors and switches.

With "quiet-ride" ranking as one of the top five reasons for purchase of prestige-luxury vehicles, especially among current LS owners, the LS 600h L is well-situated in its class and poised to please the exacting luxury-car buyer. Its NVH levels are about half that found in conventional cars, making the hybrid LS one of the quietest automobiles ever built, if not the quietest.

High-Output V8 and World's First Eight-Speed Automatic Transmission

The LS 460 and LS 460 L will be powered by an all-new, highly advanced 4.6-liter V8 engine that will produce approximately 380 horsepower and 370 pound-feet of torque. Combined with a world-first eight-speed automatic transmission, these LS sedans will travel from zero-to-sixty miles per hour in less than 5.5 seconds—all without sacrificing fuel economy. Even with this level of performance, the new LS sedans are expected to receive a combined city/highway mileage in the low-20s as well as an Ultra-Low Emissions Vehicle II (ULEV II) rating.

Advanced Active Safety Technologies

Coinciding with the launch of the hybrid model is a newly developed, Advanced Pre-Collision System (APCS) that is like nothing ever before offered by Lexus. One element of APCS is a new system designed to help detect pedestrians in the vehicle’s path.

Two small cameras mounted at the front of the car, in conjunction with millimeter-wave radar, are sensitive enough to detect not just large metal obstructions such as cars but also smaller nonmetallic objects, such as humans.

A third camera, mounted on the steering column, monitors the orientation of the driver’s face. If the camera sees that 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, the system can begin to gently apply the brakes on its own. To assist the driver in maneuvering around the obstacle, the system reprograms the steering ratio, amplifying the intensity and quickness of the steering response.While all of this is happening, the system automatically cinches up the passenger restraints and prepares the brake system to respond with full force when activated by the driver in anticipation of a possible impact.
