Infiniti’s design team took on the refined elegance of the Q70™ and provided it with a long-wheelbase treatment, adding appeal for executive carriage. The long-wheelbase version of the Q70 adds 5.9 inches to the wheelbase (from 114.2 inches to 120.1 inches) and 5.9 inches to the overall length (from 196.1 inches to 202 inches). This allows for an additional 5.6 inches of rear seat legroom (41.8 inches total) and 5.9 inches of extra knee room (32.5 inches total) for rear passengers. Height, width, and track are the same for both models. Along with its first-class style, the Q70L is designed to provide smooth, luxurious ride comfort and spaciousness for all seating positions.

The Q70L provides evocative design, invigorating performance, innovative technology and superior craftsmanship, including a choice of 3.7-liter V6 or 5.6-liter V8 engine and rear-wheel or all-wheel drive.

The available advanced technologies include Predictive Forward Collision Warning, Around View® Monitor with Moving Object Detection, Backup Collision Intervention and Forward Emergency Braking.

Also offered are an advanced Infiniti Hard Drive Navigation System, Bose^® Studio Surround^® premium audio system, Blind Spot Warning, Blind Spot Intervention^®, Lane Departure Warning and Lane Departure Prevention systems, Enhanced Intelligent Key, Intelligent Cruise Control, Distance Control Assist and Front Pre-Crash Seat Belts.

EXTERIOR

Built on the foundation of the standard Infiniti Q70, the Q70L seamlessly integrates the additional length behind the B-pillars. The design greatly augments the athletic presence of the car by providing flowing, emotional lines and refined elegance that give the vehicle an even more upscale image. The extended dimensional length of the Q70L’s rear doors enhances rear seat ingress and egress, especially for taller passengers. Automatic power rear door cinchers are also standard. On top of offering rear door auto closure, the long wheelbase version of the new Q70 provides additional features for rear passengers, such as heated rear seats, extra reading lights, and a 12V power outlet.

At first glance, Infiniti’s signature LED headlights impress immediately. An Adaptive Front lighting System (AFS) with auto-leveling headlights is available as part of the Technology Package. The distinctive multi-mode, jeweled headlights accentuate the new double arch grille, giving it a more three-dimensional look due to the elaborate detail of the high-quality waved mesh finish and chrome surround. The same solid feel is echoed in the new front bumper with integrated LED fog lights and daytime LED running lights that give the Q70L a dignified presence on the road.

From the front, the fenders create strong body lines that rise from the grille and flow through the body side from concave to convex. At the rear, the shape of the new rear LED combination lights with the design of the taillights creates a horizontal flow in motion to provide a high-quality lighting signature.

The top line of the trunk lid has been flattened while the rear bumper has been slimmed down to create a longer and lower visual impression, further emphasizing the premium sedan’s sporty and powerful styling. The chrome rear finisher adds a touch of class to the entire rear view. Other standard exterior features include a power sliding tinted glass moonroof with one-touch open/close, tilt feature and sliding sunshade, power-folding heated outside mirrors with integrated LED turn signals with reverse tilt-down feature and rain-sensing variable intermittent front windshield wipers. Also standard are courtesy lamps built into the outside door handles, rear window defroster with timer, dual exhaust with polished tips.

Stretching the Q70 into a Q70L added less than 100 lbs total to the car’s weight and the Q70L retained a low coefficient of drag of just 0.27.

INTERIOR

Reflecting the sensuous lines of the exterior, the 2015 Infiniti Q70L’s well-appointed, plush and inviting premium package interior combines style with spaciousness awash in aniline leather and sparkling wood trim. With 110.6 cubic feet of interior room (versus 103.6 cubic feet for the standard Q70), the Q70L stretches the expectations for comfort in class – including the ability of most rear seat passengers to cross their legs.

As with the standard wheelbase Q70, the instrument panel features Fine Vision gauges, gear-like rings on the instrument cluster meters, a 7-inch color vehicle information display and Infiniti analog clock. Leatherette, heated 10-way power driver and front passenger seats, including 2-way power lumbar support, are standard – along with a dual occupant memory system for the driver seat, steering wheel and outside mirrors, which can be linked to the individual Infiniti Intelligent Key fobs.

In addition, each Intelligent Key remembers the last-used climate control, audio and navigation settings. An entry/exit assist system for the driver seat and steering wheel, sequential welcome lighting illuminated entry system and dual-zone automatic temperature also add to the Q70L’s exceptional level of standard premium appointments. The new Q70L is now quieter; the engine noise and vibration levels have been lowered, even at higher speeds. Infiniti engineers have added more sound-deadening insulation materials, increased the sealing, and stiffened the wheels, resulting in a reduction of road noise on urban roads. The isolation feel at highway speeds on the long wheelbase version is a class-leading 77%, further cementing the Q70’s lead among competitors.

Contributing to the cultivated in-car atmosphere, the Active Noise Control feature monitors cabin noise levels and generates canceling sound from four door speakers to reduce noise, so it is easier to hold conversations in the car or to better enjoy the music. Premium audio systems include the Bose® Studio Surround® sound system with digital 5.1-channel decoding and 16 speakers, two of which are mounted in the shoulders of each front seat.

Other interior highlights include power windows with one-touch up/down and auto-reverse features, power door locks with automatic locking feature, retained accessory power for windows and moonroof, 6-speaker audio system with AM/FM/CD, Radio Data System (RDS), USB connection port for iPod^® interface and other compatible devices, steering wheel audio controls and speed-sensitive volume control, rear reading lamps, and a 12V rear power outlet. Rear heated seats are available with the Premium Package.

Infiniti Q70L 5.6 models add an even higher level of standard equipment, including leather-appointed seats, Infiniti Hard Drive Navigation System with 8.0-inch WVGA color touch-screen display, NavTraffic with Real-Time Traffic Information, NavWeather with Real-Time Weather and 3-day forecast (SiriusXM subscription required, sold separately), Streaming Audio via Bluetooth^®, Bose^® 2-channel 10-speaker premium audio system, heated steering wheel, climate-controlled front seats, Front and Rear Sonar Systems and Around View® Monitor with Moving Object Detection.

MECHANICAL

Staying true to Infiniti’s roots of sporty precision, the new Q70L is the result of methodical calibration by Infiniti engineers who have utilized smart technologies to achieve the exact balance of ride comfort and handling, performance and fuel economy. The Q70L is offered with a range of powerful and efficient 3.7-liter V6 and 5.6-liter V8 engines. Both are equipped with Variable Valve Event and Lift (VVEL^®), which combines hydraulic-controlled variable valve timing and electronically controlled variable valve lift on the intake side to help improve performance and response.

Throttle response is enhanced by directly controlling the intake valve rather than using the traditional method of controlling intake with the throttle valve. The VVEL system also offers improved emissions and fuel efficiency (over non-VVEL designs) by substantially reducing the intake resistance that occurs when the engine’s throttle valve opening is narrowed and output is low.

The refined 3.7-liter aluminum-alloy DOHC 24-valve V6 is rated at 330 hp at 7,000 rpm and 270 lb-ft of torque at 5,200 rpm. It features rigid ladder frame construction, large crank journal and pin diameters, molybdenum coated lightweight pistons with asymmetric skirts, twin knock sensors, iridium spark plugs and a symmetric twin air intake system.

The Q70L’s powerful 5.6-liter V8 Direct Injection Gasoline (DIG) aluminum-alloy DOHC 32-valve V8 is rated at 416 hp and 414 lb-ft of torque at 4,400 rpm. The DIG system provides better wide-open throttle performance and improved fuel economy and emissions performance (compared to a non-direct injection system) by reducing engine knock, improving combustion stability and offering more precise injection control.

Both engines are matched to Infiniti’s advanced, electronically controlled 7-speed automatic transmission with Adaptive Shift Control (ASC). The driver-adaptive learning algorithm senses driving style and adjusts automatic shifting accordingly. Manual shift mode offers sequentially selectable manual gearshifts and Downshift Rev Matching (DRM). Solid magnesium paddle shifters are also available.

The 2015 Infiniti Q70L is offered with a choice of rear-wheel drive or Infiniti’s Intelligent All-Wheel Drive (ATTESA E-TS) system, which uses an advanced torque split control strategy that automatically redistributes torque to the wheels (0:100 up to 50:50 front-to-rear) according to road and driving conditions, ensuring sure-footed road holding at all times.

In line with the focus on the driver, the new Q70L features technologies that enable individuals to customize driving feel. The unique Infiniti Drive Mode Selector allows drivers to select from four driving modes – Standard, Eco, Sport or Snow – and the integrated control system will adjust throttle sensitivity and transmission mapping to help optimize performance.

The system also adjusts Active Trace Control and Eco Pedal settings (available with the Technology Package). To support eco-driving behavior, the available Eco Pedal provides feedback directly through the accelerator pedal by giving a slight pushback if the driver is driving inefficiently.

The 2015 Q70L utilizes the advanced Infiniti Front Mid-ship (FM) platform, which positions the engine behind the front axle, resulting in an optimized front-to-rear weight balance. Laser welding is carried out at critical locations to help enhance lateral bending stiffness, torsion stiffness and suspension mounting point stiffness, which provides surefootedness and helps eliminate road harshness.

Precise handling is provided by an independent double-wishbone design at the front and multi-link independent suspension in the rear along with front and rear stabilizer bars. The rear suspension geometry has been designed to provide a quiet, comfortable ride. To increase ride comfort, Infiniti engineers have changed the shape of the oil seal lip in the shock absorbers to minimize shaking and bobbing as well as help reduce vibrations when driving on uneven roads.

The Infiniti Q70L’s large diameter wheels and tires are positioned out near the corners of the vehicle, helping to enhance performance. Standard 18-inch aluminum-alloy wheels – uniquely designed for the Q70L – and 245/50R18 all-season performance tires are offered on all models. In addition, the Performance Tire & Wheel Package offers split 5-spoke 20-inch aluminum-alloy wheels mounted with 245/40R20 all-season performance tires.

Each 2015 Q70L utilizes standard 4-wheel power-assisted vented disc brakes with Anti-lock Braking System (ABS), Electronic Brake force Distribution (EBD) and Brake Assist (BA). Sport brakes with larger rear rotors with 4-piston front/2-piston rear opposed calipers are included with the Performance Tire & Wheel Package.

The Q70L’s steering system utilizes an electronically controlled speed-sensitive variable-assist power rack-and-pinion system. Helping the driver to maintain control of the vehicle is Infiniti’s advanced Vehicle Dynamic Control (VDC) with Traction Control System.

ACTIVE TRACE CONTROL SYSTEM

The Active Trace Control system, available with the Technology Package, also adjusts engine torque and braking at each wheel to help enhance cornering performance.

INNOVATIVE TECHNOLOGIES

The 2015 Q70L’s long list of safety and security systems, which are available with the Technology Package, include the Predictive Forward Collision Warning (PFCW) system, which helps warn the driver of risks are obscured from the driver’s field of view by the vehicle traveling in the lane ahead. PFCW uses a sensor on the front of the vehicle to analyze not only the relative velocity and distance of a vehicle directly ahead, but also of a vehicle traveling in front of the preceding one. When the system detects potential risks, the system gives an alert to encourage the driver to decelerate in advance with a signal on the display, audible warning and also by tightening the seat belt. These functions work to help prevent collisions that may be caused by late brake application by the driver.

Another advanced Q70L technology is the Around View Monitor system, which helps with parallel parking. This feature shows a bird’s-eye view of the vehicle in relation to parking lines, using four vehicle-mounted cameras that create a virtual 360-degree view of what surrounds the vehicle and display it via the in-dash screen. The system includes Moving Object Detection, which helps alert the driver to moving objects around the vehicle when pulling out of a parking space or backing up.

The Backup Collision Intervention (BCI) system is a pioneering technology which intelligently helps detect crossing traffic as well as large, stationary objects behind the vehicle when in reverse. When an approaching vehicle is detected, the BCI system will provide an audible alert and a flashing light that indicates the approaching vehicle’s oncoming direction when the BSW/BSI indicator light on the side of the approaching vehicle flashes. As the vehicle gets closer, the driver hears three beeps and a red frame indicator on the in-dash display appears as an additional warning. If the driver fails to act, the system will counteract by pushing back on the accelerator pedal and even engaging the brakes momentarily.

Forward Emergency Braking (FEB) helps detect potential forward obstacles and assists the driver in avoiding or mitigating collisions within a 5-to-50 mph range.

A camera installed in the front of the vehicle monitors the presence of vehicles or pedestrians ahead and the distance to them.

If the system determines that there is a high risk of collision, it initially warns the driver with a visual signal and an audible alert. If the driver fails to decelerate, the system will apply partial braking. If the risk of a collision becomes imminent, the Forward Emergency Braking system applies harder braking automatically.

Other driver assist systems include the Lane Departure Warning (LDW) and Lane Departure Prevention (LDP) systems, which help keep the Q70L from unintentionally drifting into an adjacent lane. Using a small camera behind the windshield to detect lane markers ahead, the technologies calculate the vehicle’s position relative to those lane markers and help warn the driver of a potential unintended lane departure with visual and audible cues. If the driver does not steer the vehicle back toward the center of the lane, the LDP system assists the driver with a gentle application of the brakes.

Two other Q70L safety technologies help target driver blind spots. Blind Spot Warning (BSW) helps alert the driver to vehicles detected in the blind spot area, while Blind Spot Intervention (BSI) actively intervenes by selectively braking if the driver ignores both visual and audible warnings and attempts to steer into the path of the vehicle in the blind spot. Other features include Intelligent Cruise Control (ICC) and Distance Control Assist (DCA).

In addition, all Infiniti Q70L models come equipped with the standard Infiniti Advanced Air Bag System (AABS) with dual-stage supplemental front air bags with seat belt sensors and occupant classification sensor; standard front seat-mounted side impact supplemental air bags; and standard roof-mounted curtain side impact supplemental air bags for front- and rear-seat outboard occupant head protection.

The 2015 Infiniti Q70L also includes standard 3-point front and rear seat belts, front seat belts with pre-tensioners and load limiters and front seat Active Head Restraints with 4-way manual adjustments along with the Lower Anchors and Tether for CHildren (LATCH) system.
