Used 2017 INFINITI QX50 SUV Trims Comparison

Standard features include 18-inch wheels, automatic headlights, foglights, a sunroof, heated mirrors, keyless ignition and entry, dual-zone automatic climate control, heated power front seats (eight-way-adjustable driver, four-way passenger), leather upholstery, a tilt-and-telescoping steering wheel, a 60/40-split folding rear seat, a rearview camera, Bluetooth phone connectivity, and a six-speaker sound system with a CD player, satellite radio and a USB port.

There are multiple option packages, but as you read the descriptions, keep in mind that they have to be ordered along with those that were previously described. There's no picking and choosing.

The Premium package adds driver memory settings, a power-adjustable steering wheel, an air purifier, roof rails, an auto-dimming interior mirror and an 11-speaker Bose sound system. The Premium Plus package can be added to that, and it includes Bluetooth streaming audio, a navigation system, voice controls, front and rear parking sensors and a 360-degree parking camera system. To those packages, the Deluxe Touring package can be added. It includes 19-inch wheels (available separately), adaptive xenon headlights, an eight-way power passenger seat, two-way power driver-seat lumbar adjustment, and a power-folding backseat. And finally, to all of that, you can add the Technology package. It includes adaptive cruise control, lane departure warning and intervention, forward collision warning and automatic braking, and a blind-spot monitoring system.

There is only one engine option in the 2017 Infiniti QX50: a 3.7-liter V6 that produces 325 horsepower and 267 pound-feet of torque. A seven-speed automatic transmission and rear-wheel drive are standard, and all-wheel drive is an option.

All of that power means the QX50 is quick to accelerate, but it does come with a fuel economy penalty. EPA-estimated fuel economy is 20 mpg combined (17 city/24 highway) regardless of whether you get rear- or all-wheel drive. For comparison, the BMW X1 is substantially more fuel-efficient at 26 mpg combined, while Infiniti's new QX30 is good for 27 mpg combined.
