The 3.5-liter V6 supplying power to the EX is the famed VQ — the engine that WardsAuto.com placed on their list of "10 Best Engines" 14 years in a row.[1] The engine block is crafted aluminum alloy to help reduce weight and increase responsiveness. Air is fed through a high-flow dual intake to help the engine breathe more freely.

Without being removed from your pocket or purse, the Infiniti Intelligent Key communicates with the Infiniti EX as you approach, signaling the vehicle to unlock your door or trunk when you touch the sensor. Once inside, the Infiniti Intelligent Key lets you start the engine with a touch of the Push Button Ignition, then signals the seat, steering wheel and mirrors to adjust to your personalized memory settings.

The Infiniti Controller ? along with the steering wheel, pedals and shifter ? is how you communicate with your EX. Audio, information and available navigation systems can be controlled by either the multi-function control knob, standard push buttons or steering wheel controls, allowing you to choose the method of interaction that best suits your needs. With available Infiniti Voice Recognition, you can even use the sound of your voice.

In certain rear collisions, front-seat Active Head Restraints move upward and forward to help cushion the head, and to help assist in reducing whiplash-type injuries.

Lower anchor points are located in the lower rear outboard seating positions where the seatback and seat cushion meet, and top tether anchors are located on the back of each rear seatback. These allow the placement of LATCH System child-restraint seats in the rear seat. LATCH System seats allow easy installation and secure attachment without the need for ALR seat belts or locking clips. They meet the new federal standards.

Infiniti integrated Traction Control System (TCS) senses wheelspin while accelerating and automatically reduces engine output and/or brakes the spinning wheel to help regain traction.

To help optimize braking performance for a variety of vehicle loads, EBD adjusts the amount of brake force applied to the front and rear wheels for improved braking performance, reducing front-end dive under braking, and producing more even brake wear.

In emergency braking situations, some drivers may not brake hard enough, soon enough. Brake Assist monitors how you apply the brakes and, sensing emergency braking, works with the standard ABS system to apply maximum brake pressure for potentially shorter stops.

Infiniti large, 4-wheel ventilated disc brakes include a 4-wheel, 4-channel Anti-lock Braking System (ABS) to help the driver maintain steering control while braking.

Acting in tandem with the Traction Control System, VDC[1] compares actual vehicle cornering performance to the driver?s input, adjusting power levels and/or applying appropriate brake pressure to individual wheels to help correct oversteer or understeer.

The Infiniti Vehicle Immobilizer System embeds an encoded transponder chip into the Infiniti Intelligent Key. The engine control computer will not allow the engine to start without the correct key and transponder.

The Vehicle Security System, which is activated and deactivated using the Infiniti Intelligent Key, will sound the alarm if intrusion via doors, hood or trunk is detected.

[1] Air bags are only a supplemental restraint system; always wear your seat belt. Even with the occupant-classification sensor, rear-facing child restraints should not be placed in the front-passenger?s seat. Also, all children 12 and under should ride in the rear seat properly secured in child restraints, booster seats, or seat belts according to their size. Air bags will only inflate in certain accidents; see your owner?s manual for more details.
