Safety

For enhanced safety, the front and rear seat shoulder belts of the Infiniti QX50 have pretensioners to tighten the seatbelts and eliminate dangerous slack in the event of a collision. The BMW 3 Series Gran Turismo doesn’t offer pretensioners for the rear seat belts.

For enhanced safety, the front seat shoulder belts of the Infiniti QX50 are height-adjustable to accommodate a wide variety of driver and passenger heights. A better fit can prevent injuries and the increased comfort also encourages passengers to buckle up. The BMW 3 Series Gran Turismo doesn’t offer height-adjustable seat belts.

Over 200 people are killed each year when backed over by motor vehicles. The QX50 Essential offers optional Backup Collision Intervention which use rear sensors to monitor and automatically apply the brakes to prevent a rear collision. The 3 Series Gran Turismo doesn’t offer backup collision prevention brakes.

To help make backing safer, the QX50 Essential’s optional cross-path warning system uses wide-angle radar in the rear bumper to alert the driver to vehicles approaching from the side, helping the driver avoid collisions. The 3 Series Gran Turismo doesn’t offer a cross-path warning system.

Both the QX50 and the 3 Series Gran Turismo have standard driver and passenger frontal airbags, front side-impact airbags, driver and front passenger knee airbags, side-impact head airbags, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, daytime running lights, rearview cameras, available all wheel drive, lane departure warning systems, blind spot warning systems and around view monitors.

Warranty

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 3 Series Gran Turismo’s 4-year/50,000-mile basic warranty expires 10,000 miles sooner.

Infiniti’s powertrain warranty covers the QX50 2 years and 20,000 miles longer than BMW covers the 3 Series Gran Turismo. Any repair needed on the engine, transmission, axles, joints or driveshafts is fully covered for 6 years or 70,000 miles. Coverage on the 3 Series Gran Turismo ends after only 4 years or 50,000 miles.

Reliability

J.D. Power and Associates’ 2018 survey of the owners of three-year-old vehicles provides the long-term dependability statistics that show that Infiniti vehicles are more reliable than BMW vehicles. J.D. Power ranks Infiniti fourth in reliability, above the industry average. With 7 more problems per 100 vehicles, BMW is ranked 8th.

Engine

The QX50’s 2.0 turbo 4 cyl. produces 20 more horsepower (268 vs. 248) and 22 lbs.-ft. more torque (280 vs. 258) than the 330i Gran Turismo’s standard 2.0 turbo 4 cyl.

Transmission

The QX50 has a standard continuously variable transmission (CVT). With no “steps” between gears, it can keep the engine at the most efficient speed for fuel economy, or keep it at its peak horsepower indefinitely for maximum acceleration. The 3 Series Gran Turismo doesn’t offer a CVT.

Brakes and Stopping

For better stopping power the QX50’s standard brake rotors are larger than those on the 3 Series Gran Turismo:

12.3 inches

Tires and Wheels

For better traction, the QX50 has larger standard tires than the 3 Series Gran Turismo (235/55R19 vs. 225/50R18). The QX50 Essential’s optional tires are larger than the largest tires available on the 3 Series Gran Turismo (255/45R20 vs. 225/45R19).

For better ride, handling and brake cooling the QX50 has standard 19-inch wheels. Smaller 18-inch wheels are standard on the 3 Series Gran Turismo. The QX50 Essential’s optional 20-inch wheels are larger than the 19-inch wheels optional on the 340i Gran Turismo.

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 3 Series Gran Turismo doesn’t offer vehicle monitored tire inflation.

Suspension and Handling

For better handling and stability, the average track (width between the wheels) on the QX50 is 3.6 inches wider in the front and 1.6 inches wider in the rear than the track on the 3 Series Gran Turismo.

For better maneuverability, the QX50’s turning circle is 4 feet tighter than the 3 Series Gran Turismo’s (36.4 feet vs. 40.4 feet).

Chassis

The Infiniti QX50 may be more efficient, handle and accelerate better because it weighs about 150 to 200 pounds less than the BMW 3 Series Gran Turismo.

The QX50 is 5.2 inches shorter than the 3 Series Gran Turismo, making the QX50 easier to handle, maneuver and park in tight spaces.

The QX50 uses computer-generated active noise cancellation to help remove annoying noise and vibration from the passenger compartment, especially at low frequencies. The 3 Series Gran Turismo doesn’t offer active noise cancellation.

Passenger Space

The QX50 has 2.7 inches more front shoulder room, .8 inches more rear headroom and 3 inches more rear shoulder room than the 3 Series Gran Turismo.

Towing

The QX50 AWD Essential offers up to a 3000 lbs. towing capacity. The 3 Series Gran Turismo has no towing capacity.

Ergonomics

The QX50 offers a 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 3 Series Gran Turismo doesn’t offer a remote starting system.

The QX50 Essential’s optional easy entry system raises the steering wheel and glides the driver’s seat back when the door is unlocked or the ignition is switched off, making it easier for the driver to get in and out. The 3 Series Gran Turismo doesn’t offer an easy entry system.

To improve rear visibility by keeping the rear window clear, the QX50 has a standard rear wiper. The 3 Series Gran Turismo doesn’t offer a rear wiper.

To shield the driver and front passenger’s vision over a larger portion of the windshield and side windows, the QX50 has standard extendable sun visors. The 3 Series Gran Turismo doesn’t offer extendable visors.

Optional air-conditioned seats in the QX50 Essential keep the driver and front passenger comfortable and take the sting out of hot seats in summer. The 3 Series Gran Turismo doesn’t offer air-conditioned seats.

Model Availability

The QX50 is available in both front-wheel drive and four-wheel drive configurations. The 3 Series Gran Turismo doesn’t offer a two-wheel drive configuration.
