Matching the inspired Infiniti Q50 exterior design and new performance technology is an interior created to the same extraordinary standards. The interior environment offers a powerful blend of three-dimensional textures, highest craftsmanship and premium quality, combining modern luxury and user-focused advanced technology. The roomy interior space offers ample front and rear head room, ample rear knee room enhanced by the seatback design.

The front and rear seats are a new breakthrough in ergonomic design, developed to help distribute body pressure across a wider range of the upper seating surface. The new thin front seatback design provides for greater front seat slide and lift adjustability. Front and rear seat hip points have also been adjusted for greater support for the pelvis and the self-weight of the chest. The product of extensive research into human posture; it strikes an exquisite balance between beauty and comfort.

The Q50 is equipped with an 8-way power driver seat (slide, recline, lift, thigh support) with manual lumbar support and an 8-way power passenger seat (slide, recline, lift, thigh support). The Q50 also has standard leatherette seating surfaces and available leather seats (front and rear). The Q50 HEV has leather standard.

The Q50’s instrument panel utilizes Infiniti’s “double wave” design tradition, while updated with a new asymmetrical flow from the top of the center cluster to the wide center console. Access to all key operations and controls is designed so that the driver does not need to change driving posture, including use of hard switches, touch panels and drive mode selector controller.

Active Noise Control

The Q50 HEV’s quiet cabin is augmented by Active Noise Control.

Active Noise Control detects low-frequency engine sounds in the cabin and generates acoustically opposite sound waves to cancel the engine sounds.

The Active Noise Control system on the Q50 uses the front door woofer, rear door speaker and rear woofer on vehicles equipped with Bose® audio systems to generate anti-phase sound waves.

Anti-phase sound waves are in opposite phase to the undesirable engine sounds to be canceled. Undesirable engine sounds include low-frequency sounds created at low engine speed when optimizing performance for fuel economy and from exhaust back pressure during high-performance driving.

Based on signals detected by the front and rear microphones, the BOSE® amplifier generates antiphase sound waves weakening interior engine booming noise in real time. This is done according to a unique algorithm by a Digital Signal Processor (DSP) built in the BOSE® amplifier.

The BOSE® amplifier mixes the sound signal received from the AV control unit with the engine sound that is generated in the BOSE® amplifier and transmits the sound signal to each speaker. It is not white noise. It is not masking other noises. It is simply going head-to-head with the engine noise and canceling it, so the customer can hear what they really want to hear.

NOTE: Active Noise Control even works when the sound system is turned off.

Just as an audio system's speakers transmit sound in waves at various frequencies, so does the engine of the car. Active Noise Control monitors engine sound such as the 2nd and/or 3rd engine rev at 700-5000 rpm and then sends out a signal mixing the anti-phase sound that is directly opposite of the engine noise. Active Noise Control monitors engine speed to ensure that the system cancels only undesirable engine sounds. The noise-canceling is fine-tuned using the front and rear microphones.

Active Sound Control

The active sound control (if so equipped) generates sound levels according to engine speed and driving modes through the speakers and woofer to enhance the quality of the engine sound heard in the vehicle.

During driving, the active sound control uses two different types of sound volume. When SPORTS mode is selected with Infiniti Drive Mode Selector, the sound volume is turned up compared to that of other modes. The way it functions is the Display control unit receives the engine torque signal, accelerator pedal position signal and vehicle speed signal via CAN communication, and transmits them to the BOSE® amplifier via AV communication.

The BOSE® amplifier calculates the frequency of a canceling sound from the engine speed signal, engine torque signal, accelerator pedal position signal, and the vehicle speed signal. It the transmits the canceling sound signal to each speaker.

NOTE: The BOSE® amplifier judges the two types of sound tuning modes: SPORT and NORMAL modes.

When SPORT mode is selected, the more engine noise is allowed in the vehicle cabin.
