Lexus IS 350, 2009
Inside the Lexus IS,
Lexus enhanced form and function with a revised instrument panel center cluster. The paddle shifters now function in D mode, and some controls have been changed for improved convenience. The rear seat headrests are now foldable to aid rear visibility. New interior colors include Ecru (replacing Cashmere) and Light Gray (replacing Sterling), both accented by new contrast stitching on the seats, door panels, and console lid.
Engine/Transmission/Drivetrain/Performance
The 2009 Lexus IS line offers three models: The rear-wheel-drive Lexus IS 350, the rear-drive Lexus IS 250 and an all-wheel drive Lexus IS 250. The IS 250's 2.5-liter V6 engine delivers 204 horsepower at 6,400 RPM and 185 lb.-ft. of peak torque at 4,800 rpm. The Lexus IS 350's 3.5-liter V6 delivers 306 horsepower at 6,400 RPM along with 277 lb.-ft. of torque at 4,800 rpm and can accelerate the car from zero-to-60 mph in just 5.3 seconds. Both engines use aluminum cylinder blocks and heads and employ dual Variable Valve Timing with intelligence (VVT-i), which controls timing on both the intake and exhaust camshafts.
A direct-type fuel-injection system provides a cooling effect in the cylinders, enabling the high compression needed to extract maximum energy from the fuel. Aside from its larger displacement, the 3.5-liter V6 differs chiefly 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, increasing power and efficiency. A dual exhaust system reduces backpressure at higher engine speeds. All 2009 Lexus IS models meet the Ultra-Low Emission Vehicle II (ULEV II) certification
Chassis/Body/Suspension/Tires/Brakes
The Lexus IS is engineered to provide for a sporty driving experience. Its double-wishbone front suspension features a high-mount upper control arm, and the lower arm uses a large, liquid-filled bushing at the rear to minimize vibration and harshness. The multilink rear suspension emphasizes precise control of geometry in all dynamic conditions, helping make the Lexus IS sport sedans ultra-stable for confident driving. High-strength steel and aluminum suspension components reduce unsprung weight, helping the Lexus IS remain stable on bumpy surfaces and improving ride comfort.
Safety/Security Features
Passive-safety technology in the Lexus IS begins with a reinforced passenger compartment that helps protect the occupants with front- and rear-crush structures. Seatbelt pre-tensioners and force limiters are used for the front and outboard rear seats.
In addition to the dual-front airbags and front seat-mounted side airbags, the Lexus Supplemental Restraint System (SRS) for the Lexus IS includes side-curtain airbags that extend from A-pillar to C-pillar, and a knee airbag for both the driver and the front passenger. Advanced dual-stage front airbags are designed to deploy at one of two speeds, according to impact force. The driver's front airbag also includes an extra low stage designed to deploy based, in part, on the seat's position on its track. The front passenger airbag features two chambers, creating an indentation in the center impact area that helps to disperse the force of the bag.
Luxury/Comfort/Convenience
Standard amenities for the Lexus IS models include 10-way power front seats, dual-zone automatic climate control with rear-seat vents and a pollen filter (plus a smog filter on Lexus 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. The Lexus IS 250 AWD model in addition features standard heated, leather-trimmed seats.
Luxury Options
A Premium Plus Package that is optional for all Lexus IS models includes wood trim, perforated leather seating trim and heated and ventilated front seats. The comprehensive "Sport" and "Luxury" option packages also include three-position memory for seats, steering wheel and outside mirrors, rain-sensing wipers, power tilt and telescopic steering column and auto-dimming outside mirrors.
Exterior Design
The Lexus IS sedans show a strong family resemblance to the Lexus GS models while establishing their own distinctively sporty identity. A notably wide stance and long wheelbase, coupled with tightly drawn bodywork, give the Lexus IS an athletic, road-hungry yet sophisticated style. Carefully shaped body contours, a subtle ducktail-curved trunk lid and "air kick" tail lamps contribute to a low 0.28 coefficient of drag (Cd).
Interior Design
The Lexus IS models' luxurious cabin features intelligently designed displays and controls that are easy to see and use. Bright, clear Optitron gauges and smartly integrated metallic trim, or available Bird's-eye Maple trim, help create an elegant yet sporty environment. Premium interior materials and meticulous attention to detail convey the Lexus identity.
