IS 2009

The IS model line moves into 2009 with an impressive makeover: a revised exterior and interior revisions that enhance the overall design. New exterior features include a revised front bumper and grille, redesigned lower intake area, revised tail lamps and integrated turn-signal side mirrors. On the interior, the IS benefits from the addition of dark gray or espresso bird's-eye maple trim. This is complemented by contrast stitching which has been added to the seating, door panels and armrest.

Also new for 2009 is the adoption of Vehicle Dynamics Integrated Management (VDIM) [1] for the IS 250. Previously only available on the IS 350, VDIM has the capability to sense a loss of traction before it occurs, giving it an advantage over most conventional stability-control systems that only react after a loss of traction has occurred. Performance specifications remain the same for 2009. The IS 250 is equipped with a 2.5-liter V6 engine that puts out 204 hp [2] and 185 lb-ft of torque [2]. The IS 350 comes with a 3.5-liter V6 with 306 hp [2] and 277 lb-ft of torque [2].

[1]Vehicle Dynamics Integrated Management (VDIM) is an electronic system designed to help the driver maintain vehicle control under adverse conditions. It is not a substitute for safe driving practices. Factors including speed, road conditions and driver steering input can all affect whether VDIM will be effective in preventing a loss of control. See Owner's Manual for further details. [2]Ratings achieved using the required premium unleaded gasoline with an octane rating of 91 or higher. If premium fuel is not used, performance will decrease. [3]MSRP does not include delivery, processing and handling fee of $910. Excludes taxes, title, license and optional equipment. Dealer price may vary. Does not include accessory options installed by dealer. [4]Delivery, processing and handling fee is based on the value of the processing, handling and delivery services Lexus provides, as well as Lexus' overall pricing structure. Lexus may make a profit on the delivery, processing and handling fee. [5]Performance figures are for comparison only and were obtained with prototype vehicles by professional drivers using special safety equipment and procedures. Do not attempt. [6]EPA MPG Estimates. Actual mileage will vary. [7]Brake Assist is designed to help the driver take full advantage of the benefits of ABS. It is not a substitute for safe driving practices. Braking effectiveness also depends on proper brake-system maintenance, tire and road conditions. [8]17-in performance tires are expected to experience greater tire wear than conventional tires. Tire life may be substantially less than 20,000 miles, depending upon driving conditions. Back to top
