2014 Lexus RX 450h hybrid continues the evolution of the groundbreaking vehicle, which offers an impressive fuel economy and off-road capabilities. Case in point, the RX 450h hybrid offers the performance of 295 combined system horsepower, with substantial torque at all speeds.

Convenience and ease of use make another leap in the 2014 Lexus RX 450h with the addition of available Siri Eyes Free Mode technology licensed from Apple. Compatible with the iPhone 4S and iPhone 5 models forward, Siri lets you call contacts, select and play music from iTunes, get turn-by-turn navigation through Siri and Apple maps, and much more. To help you keep your eyes on the road and hands on the wheel, Siri can read notifications and calendar information and allow you to add reminders, calendar appointments and notes.

The standard extras include 10-way power front seats, ebony or espresso bird's eye maple and dual-zone automatic climate control, a premium audio including 9-speaker Lexus Premium Audio System offers a multitude of music source choices, Bluetooth audio streaming, USB/iPod® control and SiriusXM® Satellite Radio.

The standard SmartAccess system combines push-button starting and touch-sensitive exterior door handles. When the driver turns off the ignition, the seat automatically slides up to two inches rearward and the power tilt/telescoping steering wheel tilts upward and slides forward to ease exit. The next time the driver is seated and pushes the "On" button, the seat and steering wheel return to their preset positions automatically.

The standard Vehicle Dynamics Integrated Management (VDIM) anticipates loss of vehicle control and governs all of the vehicle's dynamic handling systems – the Anti-lock Braking System, Brake Assist (BA), Vehicle Stability Control (VSC) and Traction Control (TRAC) – coordinating with the electronic throttle control system. VDIM employs these systems collectively and seamlessly to help make corrections while allowing higher dynamic capability. The system also provides a limited slip differential effect.

The optional Pre-Collision System (PCS) with Dynamic Radar Cruise Control uses millimeter-wave radar to measure and help maintain a pre-set following distance from a vehicle traveling directly ahead. The radar sensor can detect certain obstacles in front of the car, and a PCS computer with vehicle-speed, steering angle and yaw-rate inputs helps to determine whether a collision is imminent. In such a situation, PCS preemptively retracts front seat belts and pre-initializes Brake Assist so that increased braking will be applied the instant the driver depresses the pedal.
