The 3.5-liter V6 supplying power to the M35 is the famed VQ—the engine that Ward's 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. Airflow is optimized for both low- and high-speed operation with a variable-flow induction system. The lightweight titanium intake and exhaust valves allow for even quicker response.

Without being removed from your pocket or purse, the Infiniti Intelligent Key communicates with the Infiniti M 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.

This technology seamlessly links your compatible cell phone to the Infiniti M's onboard computer system the moment you touch the vehicle's Push Button Ignition. Access phone numbers, answer and make calls through the vehicle's audio system. All without taking your hands off the wheel, or your eyes from the road.

*Requires compatible cellular phone.

You like the cabin a bit cooler. Your companion prefers it a touch warmer. The Infiniti M quickly accommodates both of you by allowing each front occupant to choose his or her very own micro-climate. The double curve of the dash also aids in creating separate climate zones.

Quickly achieving the desired cabin temperature no longer requires a blast of air to the face or hands. Mild-flow vents circulate air over and around passengers, quickly but gently cooling or warming the entire cabin.

The Infiniti Controller ? along with the steering wheel, pedals, and shifter ? is how you communicate with your Infiniti M with Bluetooth® Hands-Free Phone System. It features a high-resolution screen, easy-to-understand manual controls and optional voice input. The optional voice input allows you to control navigation, audio and climate control systems. Some systems can also be individually controlled by either the multi-functional control knob, standard push buttons or steering wheel controls, letting you choose the method of interaction that best suits your needs.

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.

Anchor points are located in the rear lower outboard seating positions where the seatback and seat cushion meet and a top tether anchor is located on the parcel shelf. They allow the placement of LATCH System compliant 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.

Infiniti M's 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.

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.

[1] VDC cannot prevent accidents caused by abrupt steering, carelessness, or dangerous driving techniques. Always drive safely.

The Vehicle Security System, which can be activated and deactivated using the remote control keyfob, will sound the alarm if intrusion via doors, hood, or trunk is detected.

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.

Infiniti M's 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.

[2] 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.
