Over 200 people are killed each year when backed over by motor vehicles. The QX50 has standard Rear Automatic Braking that uses rear sensors to monitor and automatically apply the brakes to prevent a rear collision. Backup collision prevention brakes cost extra on the RX.

Both the QX50 and the RX have standard driver and passenger frontal airbags, front and rear side-impact airbags, driver and front passenger knee airbags, side-impact head airbags, front seatbelt pretensioners, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, lane departure warning systems, blind spot warning systems, rearview cameras, rear cross-path warning, available all wheel drive and around view monitors.

The QX50 comes with a full 4-year/60,000-mile basic warranty, which covers the entire truck and includes 24-hour roadside assistance. The RX’s 4-year/50,000-mile basic warranty expires 10,000 miles sooner.

The QX50’s corrosion warranty is 1 year longer than the RX’s (7 vs. 6 years).

Infiniti pays for scheduled maintenance on the QX50 for 2 years and 26000 miles longer than Lexus pays for maintenance for the RX (3/36,000 vs. 1/10,000).

The QX50’s 2.0 turbo 4-cylinder produces 22 more horsepower (268 vs. 246) and 47 lbs.-ft. more torque (280 vs. 233) than the RX 350h’s standard 2.5 DOHC 4-cylinder hybrid.

On the EPA test cycle the QX50 gets better mileage than the RX:

The QX50 has a standard easy tire fill system. When inflating the tires, the vehicle’s integrated tire pressure sensors keep track of the pressure as the tires fill and tell the driver when the tires are inflated to the proper pressure. The RX doesn’t offer vehicle monitored tire inflation.

Changing a flat tire near traffic can be dangerous and inconvenient. The run-flat tires standard on the QX50 can be driven up to 50 miles without any air pressure, allowing you to drive to a service station for a repair. The RX doesn’t offer run-flat tires.

For greater off-road capability the QX50 has a greater minimum ground clearance than the RX 350 (8.6 vs. 8.1 inches), allowing the QX50 to travel over rougher terrain without being stopped or damaged. The QX50’s minimum ground clearance is .4 inch higher than on the RX 350h (8.6 vs. 8.2 inches).

The Infiniti QX50 may be more efficient, handle and accelerate better because it weighs about 300 to 550 pounds less than the Lexus RX.

The QX50 is 7.8 inches shorter than the RX, making the QX50 easier to handle, maneuver and park in tight spaces.

The design of the Infiniti QX50 amounts to more than styling. The QX50 has an aerodynamic coefficient of drag of .32 Cd. That is lower than the RX (.35) and many sports cars. A more efficient exterior helps keep the interior quieter and helps the QX50 get better fuel mileage.

The QX50 uses computer-generated active noise cancellation to help remove annoying noise and vibration from the passenger compartment, especially at low frequencies. The RX doesn’t offer active noise cancellation.

The QX50 has 1.5 inches more front headroom, .5 inches more rear headroom, 1.3 inches more rear legroom and .6 inches more rear shoulder room than the RX.

The QX50 has a much larger cargo volume with its rear seat up than the RX with its rear seat up (31.4 vs. 29.6 cubic feet). The QX50 has a much larger cargo volume with its rear seat folded than the RX with its rear seat folded (65.1 vs. 46.2 cubic feet).

The QX50 has a standard remote vehicle starting system, so the vehicle can be started from inside the driver's house. This allows the driver to comfortably warm up the engine before going out to the vehicle. The climate system will also automatically heat or cool the interior. The RX doesn’t offer a remote starting system.

To quickly and conveniently keep personal devices charged without cables tangling and wearing out, the Infiniti QX50 has a standard wireless phone charging system (Qi) for the front seat. Wireless charging costs extra on the RX.
