2010 Lexus HS 250h Overview Part IV: Comfort and Convenience

Comfort and Convenience
When more than one driver uses the HS 250h, an available new memory system allows individual driver settings to be recalled automatically by individual keys, saving the drivers the trouble of recalling their particular setting. The system memorizes the steering-wheel position, seat position, exterior mirror positions and air conditioning settings associated with each key, translating to shorter preparation time prior to driving.

Leather-trimmed seating is standard with a 10-way power-adjustable front seat, including power lumbar, for the driver. The passenger receives a standard eight-way power-adjustable seat, with a 10-way power-adjustable option. Heated or heated/ventilated front seats trimmed in semi- aniline leather are available in premium grade vehicles.

Climate control in the HS 250h is designed to provide comfort and clean air for all passengers. A dual temperature control system is used for front seat occupants and a dedicated rear blower mounted in the center console promotes quick cool down for the rear passengers. A plasma cluster ion generator, A/C clean air filter and a pollen removal mode help purify air inside the cabin. The interior get a little extra help from the windshield, which has infrared-ray reduction properties that help keep the interior cool, allowing a smaller size air conditioning system than would otherwise be required.

A 10-speaker, 137-watt Lexus premium audio system featuring a six-disc CD changer, a subwoofer and center speaker is standard. The system uses two-way woofer and tweeter systems in both front and rear for rich, clear sound quality.

Audiophiles will appreciate the HS 250h’s available Mark Levinson® 5.1-channel Premium Surround Sound system. Power is rated at 330 watts at only 0.1% total harmonic distortion from 20-20, 00 Hz, and the system uses 15 strategically placed speakers for outstanding audio performance and sound quality.

The HS250h accommodates a variety of music sources, providing standard auxiliary and USB inputs, Bluetooth® Audio wireless connectivity and standard XM® satellite radio capability (requires subscription after a three-month trial). Standard voice recognition and Bluetooth technology allow phone calls to be made and received while driving. When an iPod® is attached via the USB port, information such names for the artist, track and album is displayed on the available navigation or audio screen.

Noise and Vibration
As the newest member of the Lexus family and in keeping with its environmentally advanced design, aggressive noise and vibration targets were set for the HS 250h. A comprehensive and painstaking approach was taken with particular efforts directed at engine and booming noise as well as wind noise.

Component solutions on the HS include acoustic windshield glass and an extensive package of optimally positioned sound insulation materials. Measures such as dynamic dampers for the engine mounts, dual intake resonators and optimized muffler capacity were employed to achieve a smooth, linear sound quality without unnatural peaks and valleys.

Extensive aerodynamic work was conducted with both computational fluid dynamic (CFD) analysis and wind tunnel evaluation to identify noise sources, assist designers to create appropriate design elements and prove countermeasures. For example, a smoother transition between the windshield and roofline (backed by a sound-insulating inner layer) has improved air-flow and turbulence, reducing wind noise in the process.

Also, strategically placed seals, barriers and insulation material are used throughout the HS to eliminate noise paths and insulate passengers from noise sources.
