The QX70 lineup starts with the 3.7 Core Model, which delivers the vehicle’s main appeal: sport-sedan-like driving, strong V6 power, a low-slung shape, and an upscale cabin. The Performance model, sold as the 5.0 AWD, adds a stronger V8, standard all-wheel drive, larger brakes, richer seating, and more built-in convenience and parking technology.
The Core Model trim level — the 3.7 — is the standard QX70 experience, blending a sporty, driver-focused character with everyday luxury.
Best for: Drivers who want the QX70’s distinctive style, strong performance, and upscale cabin without making the V8 and extra technology the priority.
Highlights
The Performance trim level — the 5, sold as the 5.0 AWD — is the fully equipped, V8-powered version focused on stronger acceleration and added luxury.
Best for: Drivers who want the QX70’s strongest engine, standard all-wheel drive, upgraded brakes, and key comfort and parking features without relying on option packages.
Highlights
Over the Core Model, the Performance trim adds a 390-hp V8, standard all-wheel drive, larger brakes, quilted climate-controlled front seats, driver memory settings, navigation, and a surround-view parking camera system.

They identify the engine size. The 3.7 uses a 3.7-liter V6 with 325 hp, while the 5.0 AWD uses a 5.0-liter V8 with 390 hp. The V8 version appeared under the QX70 name for 2014.
INFINITI mainly identified QX70 versions by engine size rather than familiar labels such as base, midlevel, and luxury. Many upgrades on the V6 were grouped into option packages, while the 5.0 AWD bundled more equipment as standard.
The 3.7 is the core V6 model with 325 hp. The 2014 5.0 AWD adds a 390-hp V8, standard all-wheel drive, larger performance brakes, navigation, parking cameras, upgraded leather seats, front-seat cooling, and driver memory.
No. Beyond its stronger V8, the 2014 5.0 AWD includes larger performance brakes and equipment often bundled separately on V6 models, including navigation, a surround-view camera, cooled front seats, and driver memory.
In recent years, the 3.7 includes heated leather-appointed front seats, power adjustments for both front seats, an 11-speaker Bose audio system, a power moonroof, and a power liftgate. It uses a 325-hp V6 and seven-speed automatic.
The 3.7 is the sensible everyday pick for most shoppers. It retains the QX70’s 325-hp V6, leather-appointed heated seats, Bose audio, moonroof, and power liftgate without the V8 model’s performance-focused hardware.
Look for the 2014 5.0 AWD. Its 390-hp V8 is the strongest QX70 engine, and it pairs standard all-wheel drive with larger brakes designed for stronger stopping performance.
The 2014 5.0 AWD includes climate-controlled front seats, which provide heating and cooling. The core 3.7 includes heated front seats, while additional V6 equipment depends on the option packages fitted to that used vehicle.
The 2014 5.0 AWD includes an 8-inch navigation screen, a surround-view camera, moving-object detection, and front and rear parking sensors. On V6 examples, these features depend on the installed option packages.
Not as a rule across the full run. The 5.0 AWD includes all-wheel drive by definition, and the final 2017 lineup was sold as a 3.7 AWD. Check the badge and vehicle details because earlier V6 configurations varied.
The 2014 5.0 AWD has the upgraded braking hardware. It uses larger performance brakes with four-piston front and two-piston rear calipers, distinguishing it from the core 3.7 beyond the engine change.
No. In the final model year, Limited was an appearance and equipment package for the QX70 rather than a separate engine-based trim. Check the individual vehicle’s equipment instead of treating Limited as another powertrain model.
Only if the V8, stronger acceleration, larger brakes, and bundled luxury equipment are priorities. The 5.0 AWD was limited to the 2014 QX70 lineup; the more common 3.7 still delivers 325 hp and the model’s core sporty character.
