2013 Infiniti QX70 3.7 V6 (320 Hp) Automatic AWD

The Infiniti QX70 3.7 V6 Automatic AWD, introduced in 2013, is a mid-size luxury crossover SUV that distinguished itself with a focus on style and performance. Positioned as an alternative to more conventional SUV designs, the QX70 blended a coupe-like silhouette with the practicality of an all-wheel-drive system. This specific variant, featuring the 3.7-liter V6 engine paired with a seven-speed automatic transmission and all-wheel drive, was a core offering within the QX70 lineup, aiming to strike a balance between power, comfort, and all-weather capability. It played a key role in Infiniti’s strategy to attract buyers desiring a more dynamic and visually appealing SUV.

Technical Specifications

Powertrain & Engine Architecture

The QX70 3.7’s powertrain centers around the VQ37VHR 3.7-liter V6 engine. This engine is part of Nissan/Infiniti’s renowned VQ engine family, celebrated for its smooth operation and durability. The “VHR” designation indicates Variable Valve Timing and lift control, which optimizes engine performance throughout the rev range. Direct fuel injection further enhances both efficiency and power output. The engine generates 320 horsepower at 7000 rpm and 265 lb-ft of torque at 5200 rpm. The seven-speed automatic transmission, sourced from Aisin, delivers smooth and relatively quick shifts. The all-wheel-drive system is primarily rear-biased, channeling power to the rear wheels during normal driving and engaging the front wheels when traction is compromised. This configuration contributes to a more engaging driving experience than a full-time all-wheel-drive system.

Driving Characteristics

The QX70 3.7 Automatic AWD provides a responsive and confident driving experience. While not a dedicated sports vehicle, the 320 hp engine delivers sufficient power for everyday driving and confident passing. The seven-speed automatic transmission is well-calibrated, offering smooth gear changes and quick downshifts when needed. Compared to potential base models or future turbocharged options, this engine provides a more linear power delivery, lacking the immediate low-end torque of a turbocharger but offering a more predictable and engaging feel. The all-wheel-drive system ensures excellent traction in various weather conditions. The QX70’s weight prevents it from feeling particularly agile, but the steering is precise and well-weighted, providing a good sense of control.

Equipment & Trim Levels

The QX70 3.7 Automatic AWD generally came well-equipped, reflecting its luxury positioning. Standard features typically included leather upholstery, power-adjustable front seats, a premium audio system, a navigation system, and a rearview camera. Higher trim levels, such as the Technology Package, added features like adaptive cruise control, lane departure warning, and a blind-spot monitoring system. Optional extras included a panoramic sunroof, heated and cooled front seats, and upgraded interior trim materials. The interior design prioritized a driver-centric layout with a comfortable and spacious cabin.

Chassis & Braking

The QX70 features a robust chassis with a double wishbone front suspension and an independent multi-link rear suspension. This setup provides a comfortable ride while maintaining good handling characteristics. Ventilated disc brakes are used on all four wheels, providing ample stopping power. An anti-lock braking system (ABS) is standard, enhancing safety and control during emergency braking. The suspension tuning prioritizes comfort, but it effectively manages body roll during cornering. Stabilizer bars are present at both the front and rear to further minimize body roll.

Market Reception & Comparison

The Infiniti QX70 3.7 V6 Automatic AWD was generally well-received by automotive reviewers. It was praised for its stylish design, powerful engine, and comfortable ride. However, some critics noted its relatively high fuel consumption compared to competitors. Compared to other luxury crossovers like the Acura RDX or BMW X3, the QX70 offered a more distinctive and aggressive styling. The Acura RDX, with its turbocharged engine, offered better fuel economy, while the BMW X3 provided a more sporty driving experience. The QX70 carved out a niche by appealing to buyers who prioritized style and performance over ultimate fuel efficiency.

Legacy

The VQ37VHR engine, in general, has proven to be a reliable and durable powerplant. The seven-speed automatic transmission has also demonstrated good long-term reliability. However, as with any vehicle, regular maintenance is essential for longevity. Common issues reported with the QX70 include oil consumption (a characteristic of the VQ engine family) and potential problems with the timing chain tensioners. On the used car market, the QX70 3.7 Automatic AWD remains a popular choice for buyers seeking a stylish and capable luxury crossover. Its distinctive design and powerful engine continue to appeal to those who want an SUV that stands out. Its relative affordability compared to newer luxury crossovers also makes it an attractive option.
