The 2017 Infiniti QX70 stands out as a performance-oriented midsize luxury crossover powered by a robust 3.25-horsepower 3.7-liter V6 engine. Built on a sports-car-derived rear-wheel-drive platform, the final-year QX70 delivers engaging driving dynamics and bold styling, though it trades off fuel efficiency, rear cargo capacity, and modern infotainment integration compared to more practical rivals.
Overview and Legacy of the 2017 Infiniti QX70
The 2017 model year marked the end of an era for Infiniti. As the final production year of the second-generation QX70 lineup—originally introduced in 2009 as the Infiniti FX37 and FX50—the 2017 QX70 represents the peak refinement of Infiniti's performance crossover concept. When Nissan’s luxury division launched the original FX series in the early 2000s, it pioneered the "coupe-style crossover" segment long before European competitors embraced sloping rooflines on utility vehicles.
Unlike traditional SUVs that rely on truck-based ladder frames or front-wheel-drive passenger car platforms, the 2017 QX70 is built on Nissan’s famed Front Midship (FM) platform. This shared architecture—also utilized by performance vehicles like the Nissan 370Z and Infiniti G37/Q50—places the engine further back behind the front axle center line. The result is an optimized front-to-rear weight distribution that endows the QX70 with handling characteristics uncommon for a vehicle in its class.
For 2017, Infiniti streamlined the QX70 lineup into a single primary trim powered exclusively by its naturally aspirated 3.7-liter V6 engine, dropping the earlier 5.0-liter V8 option. However, to give the vehicle a distinct send-off, Infiniti introduced an exclusive Limited Package, which added bespoke exterior styling accents, upgraded lighting elements, and high-contrast interior trim.
Powertrain, Performance, and Driving Dynamics
Under the sculpted aluminum hood of every 2017 Infiniti QX70 lies the naturally aspirated 3.7-liter VQ37VHR V6 engine. Recognized for its linear power delivery and high-revving nature, this engine incorporates Nissan’s Variable Valve Event and Lift (VVEL) system to optimize throttle response, fuel burn, and high-rpm output.
Engine and Transmission Specifications
- Engine Type: 3.7-Liter 24-Valve DOHC V6 (VQ37VHR)
- Horsepower: 325 hp @ 7,000 RPM
- Torque: 267 lb-ft @ 5,200 RPM
- Transmission: 7-Speed Electronically Controlled Automatic with Adaptive Shift Control (ASC) and Manual Shift Mode
- Redline: 7,500 RPM
The 7-speed automatic transmission pairs effectively with the V6 engine. Drivers seeking manual gear selection can utilize the optional solid-magnesium paddle shifters mounted to the steering column. Downshift Rev Matching automatically blips the throttle during manual downshifts to smooth out gear changes and maintain chassis balance during aggressive deceleration.
RWD vs. ATTESA E-TS All-Wheel Drive
The 2017 QX70 was offered in standard Rear-Wheel Drive (RWD) or with Infiniti’s ATTESA E-TS (Advanced Total Traction Engineering System for All Terrains Electronic Torque-Split) Intelligent All-Wheel Drive system.
Unlike front-biased AWD systems found in competitors like the Acura MDX or Lexus RX, the QX70’s ATTESA system operates with a 100% rear-wheel bias under normal dry driving conditions. When sensors detect wheel slip, the system’s electro-magnetic clutch can divert up to 50% of available engine torque to the front wheels. This preserves the rear-drive steering feel and agility while providing low-traction capability in rain, snow, or mud.
Suspension and Handling Character
The suspension architecture of the QX70 relies on a independent double-wishbone setup at the front axle and a multi-link configuration at the rear, combined with front and rear stabilizer bars. Twin-tube shock absorbers with dual-flow valves damp body movement over bumps.
On twisty roads, the QX70 exhibits minimal body roll and precise turn-in response. However, this athletic tuning comes with a clear trade-off: the ride quality is decidedly firm. Buyers accustomed to plush, floating luxury SUVs may find the QX70’s ride overly stiff, particularly when equipped with the optional 20-inch or 21-inch alloy wheels.
Interior Design, Ergonomics, and Technology
Stepping inside the 2017 QX70 reveals a cabin that blends classic luxury craftsmanship with mid-2010s technology. The front seats feature a deep "cockpit" layout, wrapping the driver in leather and physical control switchgear.
Cabin Comfort and Materials
Infiniti used high-touch materials throughout the interior. Leather-appointed seating surfaces came standard, with power-adjustable 10-way driver seats and 8-way front passenger seats. Available equipment included climate-controlled (heated and cooled) front seats and real wood interior trim, such as Black Lacquer or Open-Pore Maple.
However, passenger space highlights the design compromise of the QX70's dramatic silhouette:
- Front Legroom: 44.7 inches (Generous for tall drivers)
- Rear Legroom: 34.6 inches (Tight for a midsize crossover)
- Cargo Volume (Seats Up): 24.8 cubic feet
- Cargo Volume (Seats Folded): 62.0 cubic feet
The sloped rear hatch penalizes vertical cargo space significantly compared to boxier midsize SUVs. Loading large furniture or bulky dog crates can prove challenging due to the narrow opening and high liftover height.
Infotainment and Driver Assistance Tech
Infotainment represents the most dated aspect of the 2017 QX70. The vehicle utilizes Infiniti's hard-button-based InTouch navigation system with an 8-inch color display.
- Standard Tech: Bluetooth hands-free phone integration, rear view monitor, USB input port, keyless entry, and push-button ignition.
- Audio Options: An available 11-speaker Bose Premium Audio System engineered specifically for the cabin layout.
- Missing Features: Factory Apple CarPlay and Android Auto were never offered on the 2017 QX70. Buyers who want smartphone projection must rely on aftermarket head-unit modifications or standalone Bluetooth receivers.
Driver assistance features were progressive for 2017 when equipped with the Technology Package. Systems include Intelligent Cruise Control, Distance Control Assist, Forward Emergency Braking, and Lane Departure Warning / Lane Departure Prevention. Additionally, Infiniti's pioneering Around View Monitor (AVM) uses four exterior cameras to create a 360-degree top-down view for low-speed parking maneuvers.

Used Market Assessment: Pros, Cons, and Reliability
Evaluated as a pre-owned vehicle, the 2017 Infiniti QX70 occupies a distinct spot in the luxury crossover market. It appeals to buyers seeking mechanical longevity, performance-focused handling, and distinct style over modern digital screens and fuel efficiency.
Key Pros
- Proven Mechanical Reliability: The 3.7L VQ37VHR V6 engine and JATCO 7-speed automatic transmission are mature, durable components. By 2017, Infiniti resolved earlier issues with galley gasket leaks found on 2008–2012 VQ37 engines by using reinforced metal gaskets from the factory.
- Distinctive Performance Handling: Thanks to its rear-biased FM platform, the QX70 drives more like a sports sedan than a high-riding SUV.
- Timeless Exterior Styling: The long hood, aggressive stance, and bulbous wheel arches give the vehicle a striking presence that has aged remarkably well.
- Value for Money: Compared to midsize German luxury crossovers of the same era (such as the Porsche Macan, BMW X5, or Audi Q7), a pre-owned 2017 QX70 often carries lower maintenance overhead and higher component longevity.
Key Cons
Poor Fuel Economy: Achieving an EPA-estimated combined rating of 18–19 MPG (and often lower in urban traffic), the QX70 is thirsty. It also requires premium unleaded gasoline (91 octane or higher).
Outdated Interior Interface: The lack of modern smartphone mirroring (CarPlay/Android Auto) and the presence of a button-heavy dash reveal the platform's mid-2000s roots.
Firm Ride Quality: The sports-tuned suspension communicates road imperfections directly into the cabin, especially models fitted with 20- or 21-inch rims.
Compromised Utility: Narrow rear legroom and limited cargo height make it less practical for family hauling duty than rivals like the Acura MDX or Lexus RX 350.

Pre-Purchase Inspection (PPI) Checklist for Used Buyers
When evaluating a used 2017 Infiniti QX70, pay close attention to the following component areas:
- Suspension and Bushings: Inspect the front lower control arm bushings and rear differential bushings for cracks or hydraulic fluid leakage. Heavy vehicle weight wears suspension rubber faster.
- Brake Wear: Check rotor thickness and brake pad wear. Aggressive driving and heavy curb weight lead to accelerated brake wear on stock rotors.
- Tire Wear Patterns: Check for uneven tread wear on models equipped with 20-inch or 21-inch wheels, which can indicate alignment drift or worn struts.
- Transfer Case & Differential Fluids: Ensure AWD models have documented fluid changes for the front/rear differentials and transfer case, ideally performed every 30,000 to 45,000 miles.
- Exhaust System Rust: Inspect the Y-pipe and rear mufflers for corrosion, particularly in cold-climate vehicles exposed to road salt.
Frequently Asked Questions
Is the 2017 Infiniti QX70 reliable?
Yes, the 2017 Infiniti QX70 is widely regarded as very reliable. Because 2017 was the final year of production, Infiniti had ironed out most mechanical vulnerabilities. The VQ37VHR engine features upgraded metal galley gaskets, and the 7-speed automatic transmission is robust when properly maintained with fluid drain-and-fills.
Does the 2017 Infiniti QX70 have Apple CarPlay or Android Auto?
No, factory Apple CarPlay and Android Auto were not offered on any 2017 QX70 models. The vehicle relies on Infiniti's legacy InTouch infotainment system. However, owners can install third-party aftermarket integration modules behind the OEM dash to add wireless CarPlay and Android Auto capabilities while retaining the factory display screen.
How much can the 2017 Infiniti QX70 tow?
The 2017 Infiniti QX70 has a maximum towing capacity of 2,000 pounds for both RWD and AWD configurations when properly equipped with a factory-approved hitch receiver and trailer harness. This is lower than some midsize luxury SUVs, reflecting its car-based FM platform and performance-focused suspension.
What model replaced the Infiniti QX70 after 2017?
Infiniti discontinued the QX70 after the 2017 model year without a direct front-midship successor. The brand redirected its focus toward the smaller, front-wheel-drive-based Infiniti QX50 (redesigned for 2019) and later introduced the QX55 coupe-crossover. However, neither vehicle shares the rear-drive architecture or V6 engine layout of the original QX70.
What is the difference between the standard QX70 and the 2017 Limited Package?
The 2017 Limited Package is primarily a visual and equipment upgrade package. Exterior enhancements include a special front fascia with integrated LED daytime running lights, a dark-mesh grille, body-color side vents, dark tail lamps, and unique 21-inch dark aluminum-alloy wheels. Inside, the Limited Package features graphite and stone leather seats with high-contrast pillow quilting, a dark headliner, and contrast stitching on the dash surfaces.
Final Verdict: Is the 2017 Infiniti QX70 Right for You?
The 2017 Infiniti QX70 remains an enticing option for enthusiast buyers seeking a stylish, reliable luxury crossover with authentic sports sedan driving dynamics. Its high-revving 3.25-horsepower V6 engine, rear-biased AWD system, and aggressive styling separate it from a sea of bland, appliance-like family haulers.
However, buyers must be comfortable with its compromises: high fuel consumption, a stiff ride, limited cargo utility, and an older interior infotainment system. If practical family transport, max cargo capacity, and low fuel costs are your top priorities, options like the Lexus RX 350 or Acura MDX are better suited. But if you value driving engagement, mechanical durability, and distinctive styling over high-tech screen real estate, the 2017 QX70 represents one of the best pre-owned luxury crossover values available on the used market.
Recommended Next Steps:
- Target 2017 models with full maintenance records, prioritizing vehicles equipped with the Technology Package for active driver safety features or the Limited Package for peak visual appeal.
- Schedule a detailed pre-purchase inspection with an independent technician specializing in Nissan/Infiniti vehicles to verify suspension bushing health and driveline fluid condition.
