The well-equipped Lexus IS sedan receives technology updates for 2010 that build on the brand’s legacy of delivering state-of-art technology. Prices start at $31,845.

To further enhance the driving experience, iPod/USB connectivity, streaming audio via Bluetooth and an integrated satellite radio receiver are added to the standard Lexus Premium Sound System.

The optional Lexus Navigation system has been updated with Voice Command casual-language voice recognition and Bluetooth phonebook download capability. The navigation system also features an integrated XM NavTraffic, XMWeather and XM Sports/Stocks receiver and comes with a complimentary 90-day trial subscription.

Finally, two all-new telematics products are available with a complimentary one-year trial subscription. Safety Connect is standard on non-navigation equipped vehicles. Lexus Enform, which automatically comes with Safety Connect, is only available with navigation-equipped vehicles.

In addition to technology enhancements, the optional Luxury Package on the IS 250 AWD now includes front ventilated seats, perforated semi-aniline leather trim and wood trim. This package features other luxury amenities such as the Adaptive Front Lighting System (AFS), Bi-Xenon High-Intensity Discharge (HID) headlamps and a power tilt-and-telescopic steering column. Finally, Espresso Bird’s-Eye Maple replaces Golden Brown Bird’s-Eye Maple for vehicles equipped with Ecru leather trim.

Performance

The IS sedan line offers four models: The rear-wheel-drive (RWD) IS 350, the rear-drive IS 250, an all-wheel drive IS 250, plus the high performance RWD IS F. 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 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.

An advanced six-speed automatic transmission with steering-wheel-mounted paddle shifters is standard on the IS 350 and the IS 250 all-wheel drive model. The rear-wheel drive IS 250 comes standard with a crisp-shifting six-speed manual transmission, with the paddle-shift automatic offered as an option.

Convenience

Standard amenities for the IS models include a leather-trimmed interior with 10-way power front seats, dual-zone automatic climate control with rear-seat vents and a pollen filter (plus a 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. The IS 250 AWD model in addition features standard heated seats.

A multi-function switch allows the driver to set an adjustable speed warning and an adjustable RPM shift light in the tachometer. Paddle shifters function in D mode and multiple controls are designed to maximize convenience for the driver. The SmartAccess keyless entry and push-button-start ignition allows the driver to keep the access fob in a pocket or purse. The standard HomeLink programmable garage door opener also operates home security devices and other systems.

Exterior

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 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).
