The Lexus RX 450h luxury crossover is one of company’s hybrid models.

When the RX hybrid first launched in it was a pioneer in the luxury hybrid

For 2012, the Lexus RX 450h Nebula Gray Pearl to the color choices as Smoky Mica is discontinued.


The RX 450h’s Lexus Hybrid features a 3.5-liter V6 Atkinson-cycle electric motors, a small and power-control unit and other innovations. It offers performance to V8s, 295 total system and in many cases better fuel economy than the four-cylinder mid-size sedan.

The Wheel Drive (FWD) has EPA-estimated 32 mpg city and 28 mpg highway (30 mpg fuel economy ratings, the All-Wheel Drive (AWD) has estimates of 30 mpg city, 28 mpg highway, 29 mpg

As a full hybrid, the 2012 RX 450h can operate in electric-only or modes as well as a mode combines the power of both. electric-mode operation during or stop-and-go driving conditions reduce fuel consumption. certain circumstances, a driver-selectable EV can allow the vehicle to be driven distances using only the motors.

The gas alone produces 245 horsepower at rpm and 234 lb.-ft. torque at 4,800 The Atkinson cycle also exhaust temperature.

A cooled Gas Recirculation (EGR) system it further still, helping by eliminating the fuel enrichment needed to help prevent overheating under high

A compact 288V DC Nickel Hydride (Ni-MH) battery fits neatly under the seat. A boost converter raises voltage to 650V DC, and an changes this to 650V AC for the 123-kW electric motor-generator. The converter and inverter are enclosed in the unit, which also the condenser.

The RX 450h FWD model’s powertrain employs two motor-generators: the engine-driven generator, is a starter and can the battery pack or power electric motors as needed; MG2 is the motor. Power from the gas and MG2 is distributed to the drive wheels via a gear-type continuously variable MG1 controls the output speed of the through the planetary gear without clutches or a viscous MG2 delivers torque over a range for better response and performance. When the RX 450h is or braking, the electric motors as generators, capturing energy would normally be lost as through the brakes and transforming it electricity to recharge the batteries.

RX 450h AWD adds a third, motor-generator (MGR) to drive the wheels, eliminating the need for gearing or a driveshaft from the The hybrid system electronically front and rear torque depending on traction conditions. A flywheel damper absorbs torque fluctuations and also the vibration produced when the engine starts and stops. A mode slows accelerator-pedal to help reduce the possibility of spin.

Multi-Mode, a feature to the vehicle’s electronically controlled variable transmission, allows the to control engine braking for maneuverability on rough or winding The Intelligent Shift Control selects and holds the optimal when driving downhill or on providing a smoother driving

The 2012 RX 450h AWD uses a rear electric motor-generator to power to the rear wheels road conditions or throttle dictates. When accelerating, or off on a low-grip surface, torque is provided to all four wheels. At speeds, torque is sent to the front wheels, enhancing efficiency. For handling agility and the AWD system increases rear-wheel when the vehicle’s front start to lose traction and rear-wheel torque when the rear tires start to traction.

The RX 450h features Adaptive Front-lighting System for high beams of HID headlamp models, and for the low beams of the LED equipped When entering a corner, AFS where the vehicle will be on the vehicle speed and the angle of the and adjusts the lateral aim of the headlamps. AFS can be off by the driver if desired and includes an function.

Also available is an high beam system uses a camera mounted on the rear view mirror to between high and low beams in to oncoming vehicles and those in front, or when other sources are detected, helping driver inconvenience.

The optional Pre-Collision System with Dynamic Radar Control uses millimeter-wave to measure and help maintain a following distance from a traveling ahead. The radar can detect certain obstacles in of the car, and a PCS computer with speed, steering angle and inputs helps to determine a collision is highly possible. In a situation, PCS preemptively retracts seat belts and pre-initializes BA so increased braking will be the instant the driver depresses the

The RX 450h is equipped with a 10 standard airbags, including curtain airbags, front side airbags, rear airbags (for the outboard positions) and knee airbags for the and the front passenger. A roll signals the side curtain to inflate if a predetermined threshold of tip-up is detected.


An available 12-speaker system system comes with the Comfort Package or rear entertainment systems and includes tweeters and a compact, L-shaped in the rear-luggage compartment.

Lexus RX owners will also all of the typical RX benefits, including interior quality and an impressively and quiet ride. The cabin boasts a bevy of high-tech — both standard and — to please most enthusiasts, including a surprisingly mouselike electronics interface, a Mark Levinson sound and LED headlamps. The optional 15-speaker Levinson Surround Sound allows listeners to enjoy 330 at 0.01 percent THD through surround sound. The Mark system, a Lexus exclusive, a center channel coaxial metal-cone midrange speakers, and a 100-watt amplified subwoofer. A speaker built into D-pillar provides the right and surround-sound channels. The diffusion of provides each occupant the level of audio quality.

2012 Lexus RX 450h offers a telematics system, Enform with Safety available by subscription. Complimentary trial subscriptions are included on all of new Lexus vehicles equipped these features. Safety is standard on all vehicles while Enform with Safety is on all vehicles equipped with the Navigation system. The Lexus and the Safety Connect response operate 24 hours a day, 7 a weekevery day of the year.

Lexus Enform vehicles are ready for subscriptions to a variety of SiriusXM services including NavWeather, Sports, and Stocks. services include complimentary trial subscriptions and require audio and data subscriptions.

The Lexus RX 450h comes a 48-month/50,000-mile basic limited with roadside assistance for 48 miles. Powertrain and restraint coverage is provided for 72 months/70,000 Corrosion perforation protection is for 72 months, regardless of mileage. The components, including the HV battery, module, hybrid control and inverter with converter, are for eight years/100,000 miles.
