- Standard Leather-Trimmed 10-Way Power Front Seats
- Available 3.5L V6 Offers 306 Horsepower
- Available F Sport Package Offers Exclusive Upgrades for IS 250/350 Rear-Wheel Drive Models
Aside from its larger displacement, the 3.5-liter V6 also differs in that it augments the direct fuel injection with port fuel injectors. In light- and medium-load conditions, these additional injectors help produce a precise burn, optimizing power and efficiency. A dual exhaust system reduces backpressure at higher engine speeds.
An advanced six-speed automatic transmission with steering-wheel-mounted paddle shifters is standard on the IS 350 models and the IS 250 AWD. The IS 250 RWD comes standard with a crisp-shifting six-speed manual transmission, with the paddle-shift automatic offered as an option.
Aiding the IS models’ traction and control is Vehicle Dynamics Integrated Management (VDIM). More advanced than other traction and stability systems, VDIM is designed to anticipate the onset of a vehicle skid or slide and help correct the situation with a combination of braking and throttle control. VDIM integration provides precise management for Electric Power Steering (EPS), Vehicle Stability Control (VSC), the Anti-lock Braking System (ABS), Brake Assist (BA), Electronic Brake force Distribution (EBD), and engine torque (via the electronically controlled throttle). The driver can disengage VSC via the "TRAC off" switch, which can be useful in certain situations.
The IS 350’s brake system is equipped with larger ventilated front and rear rotors and aluminum four-piston front calipers. Standard all-season performance tires are 225/45R17 in front and 245/45R17 for the rear (225/45R17 on IS 250 and IS 350 AWD). Eighteen-inch wheels are available.
The IS 250 offers optional High Intensity Discharge (HID) headlamps with LED daytime running lamps. IS 350 models feature standard HID headlamps with LED daytime running lamps and headlamp washers. The rear back-up camera, included with the optional navigation system, automatically projects an image of what its lens can detect behind the car onto the navigation screen when the transmission is in reverse gear. The exterior mirrors integrate turn signals.
The optional Intuitive Park Assist (IPA) system uses ultrasonic sensors to detect objects close to the car's front and rear bumpers, helping to alert the driver and showing distance to objects in the multi-information display within the speedometer. When any IS model is also equipped with the optional navigation system, information on objects detected is shown in greater detail on that system's seven-inch touch screen display.
The standard Lexus Premium Audio System features a six-disc, in-dash CD changer, 194 watts (max.) total power, 13 speakers, iPod®/USB connectivity, Bluetooth® hands free phone and music streaming and an integrated satellite radio receiver. The Automatic Sound Levelizer (ASL) maintains consistent sound levels at varying vehicle speeds.
Inside, special F Sport heated front seats feature a microfiber insert and leather side bolsters to provide more grip for the driver and passenger during cornering. The package also adds F Sport badging to the steering wheel, shift knob and doorsill scuff plates.
An optional Luxury Plus Package includes wood trim, perforated leather seating trim and heated and ventilated front seats, plus three-position memory for Driver’s seat, steering wheel and outside mirrors, rain-sensing wipers, power tilt and telescopic steering column and auto-dimming outside mirrors.
Like all Lexus models, the IS offers its own version of the Mark Levinson® Premium Surround Sound Audio system, which is available in conjunction with the optional DVD touch-screen navigation system. This 14-speaker audio system features discrete 5.1 multi-channel playback with 7.1-channel speaker architecture. Its 10 amplifier channels provide 300 watts total output at 0.1 percent total harmonic distortion (THD). The Mark Levinson system plays conventional CDs and DVDs, plus MP3/WMA-formatted CDs. DVD movies can be viewed on the optional navigation system's color seven-inch touch screen when the parking brake is engaged.
The Lexus IS also offers a telematics system, Lexus Enform® with Safety Connect®, available by subscription. Complimentary one-year trial subscriptions are included on all purchases of new Lexus vehicles equipped with these features. Safety Connect is standard on all vehicles, while Lexus Enform with Safety Connect is on vehicles equipped with the optional Navigation system. The Lexus Enform and the Safety Connect response centers operate 24 hours a day, 7 days a week—every day of the year.
Lexus Enform vehicles are factory ready for subscriptions to a variety of innovative SiriusXM services including NavTraffic, NavWeather, Sports, and Stocks. SiriusXM services offer complimentary 90-day trial subscriptions and require separate audio and data subscriptions.
A highly rigid body structure is the starting point for controlling noise intrusion. Strategically placed noise-suppression materials, including special window and door seals, acoustic windshield glass and asphalt sheeting, take over from there.
The multi-information display located within the speedometer integrates a trip computer and an oil-maintenance reminder and system warnings, all grouped in one convenient location. When equipped with the available Intuitive Park Assist (IPA), the display can show a car icon with the location and distance of objects detected near the bumpers.
