Monotube shock absorbers employ larger pistons than conventional twin-tube shocks to provide superior damping-force response and control, especially at low piston speeds. The sophisticated shock-absorber design utilizes multileaf linear control valves to help improve damping force, plus rebound springs that offer improved body control without the typical ride comfort tradeoffs. Available sport suspension with 18-inch wheels further enhances handling response.

In the IS 250, VSC helps to control loss of lateral traction while cornering by using throttle intervention and applying individual wheel braking to help control any discrepancy between where the driver is steering and where the vehicle is heading. Lexus IS 350 is exclusively equipped with Lexus' innovative VDIM system to provide superior handling dynamics and traction control.

Lexus IS 350's sport-tuned version of VDIM allows a higher intervention threshold for more spirited driving. Combining input from a variety of sensors, VDIM is designed to anticipate the onset of a vehicle skid or slide and then help correct the situation with a combination of braking and throttle control in a way that is essentially transparent to the driver. VDIM integration provides precise management for Electric Power Steering (EPS), Vehicle Stability Control (VSC), Anti-lock Braking System (ABS), Brake Assist (BA), Electronic Brake force Distribution (EBD), and engine torque (via the electronically controlled throttle). New for 2007, the IS models includes the ability to disengage VSC or VDIM via the Trac off switch, which can be useful in certain handling situations or when trying to extricate the car from snow, for example.


Advanced Steering, Powerful Brakes

The Electric Power Steering (EPS) rack and pinion steering gear helps to provide linear steering response, precise control and better straight-line stability. In addition, the vehicle-speed-sensitive system helps offer more precise control of steering assist than a traditional hydraulic system can, eliminates parasitic loss from a hydraulic pump, and reduces weight and complexity.

The Lexus IS braking systems are commensurate with their performance capability. A variable ratio link-type pedal and tierod-type booster enhance brake-pedal rigidity and system response. Lexus IS 250 features ventilated front and solid rear rotors; the IS 350 steps up to larger ventilated front and rear rotors. In addition, the IS 350's aluminum four-piston front calipers aid in heat dissipation and stopping power and reduce unsprung weight.

Standard all-season performance tires measure 225/45R17 in front and 245/45R17 for the rear (225/45R17 on AWD). Available as a stand-alone option or as part of the sport suspension, performance-tread ("summer") 225/40R18 front tires and 255/40R18 rear tires reward the enthusiast driver with even higher cornering grip.


Comfort Through Ultimate Convenience

The brand's traditional attention to comfort and convenience is abundantly present in the overtly sporty IS. The luxurious and muscular cabin features intelligently designed displays and controls that are easy to see and use. Bright, clear Optitron gauges and smartly integrated metallic or available Bird's-eye Maple trim help create an elegant yet active environment. Premium interior materials and meticulous attention to detail strongly convey the Lexus identity.

Standard amenities include 10-way power front seats; dual-zone automatic climate control with rear-seat vents and pollen filter (plus smog filter on IS 350); power moonroof with one-touch open/close and seven open-position settings; manual tilt-and-telescoping steering wheel; all power windows with automatic up/down feature and jam protection, and an auto-dimming rear-view mirror.
