Safety Comparison

The Q50 V6’s optional pre-crash front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The A4 doesn’t offer pre-crash pretensioners.

The Q50 Premium/Sport offers optional Forward Emergency Braking, which use forward mounted sensors to warn the driver of a possible collision ahead. If the driver doesn’t react and the system determines a collision is imminent, it automatically applies the brakes at full-force in order to reduce the force of the crash or avoid it altogether. The A4 doesn't offer collision warning or crash mitigation brakes.

Over 200 people are killed each year when backed over by motor vehicles. The Q50 Premium/Sport offers optional Back-up Collision Intervention which use rear sensors to monitor and automatically apply the brakes to prevent a rear collision. The A4 doesn’t offer backup collision prevention brakes.

The Q50 V6’s optional lane departure warning system alerts a temporarily inattentive driver when the vehicle begins to leave its lane and gently nudges the vehicle back towards its lane. The A4 doesn’t offer a lane departure warning system.

The Q50 Premium/Sport offers an optional Around View ® Monitor to allow the driver to see objects all around the vehicle on a screen. The A4 only offers a rear monitor and rear parking sensors that beep or flash a light. That doesn’t help with obstacles to the front or sides.

To help make backing safer, the Q50 Premium/Sport’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 A4 doesn’t offer a cross-path warning system.

The Q50 offers optional Infiniti Connection, which uses a global positioning satellite (GPS) receiver and a cellular system to get turn-by-turn driving directions, remotely unlock your doors if you lock your keys in, help track down your vehicle if it’s stolen or send emergency personnel to the scene if any airbags deploy. The A4 doesn’t offer a GPS response system, only a navigation computer with no live response for emergencies, so if you’re involved in an accident and you’re incapacitated help may not come as quickly.

Both the Q50 and the A4 have standard driver and passenger frontal airbags, front side-impact airbags, side-impact head airbags, front seatbelt pretensioners, height adjustable front shoulder belts, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, daytime running lights, available all wheel drive and blind spot warning systems.

A significantly tougher test than their original offset frontal crash test, the Insurance Institute for Highway Safety does 40 MPH small overlap frontal offset crash tests. In this test, where only 25% of the total width of the vehicle is struck, results indicate that the Infiniti Q50 is safer than the A4:

For its top level performance in the IIHS moderate overlap frontal impact, side impact, rear impact, roof-crush crash tests, an “Acceptable” rating in the newer small overlap frontal crash test, and with its optional front crash prevention system, the Insurance Institute for Highway Safety grants the Q50 its highest rating: “Top Pick Plus” for 2015, a rating granted to only 69 vehicles tested by the IIHS. The A4 is not even a standard “Top Pick” for 2015.

Warranty Comparison

The Q50 comes with a full 4 year/60,000 mile basic warranty, which covers the entire car and includes 24 hour roadside assistance. The A4’s 4 year/50,000 mile basic warranty expires 10,000 miles sooner.

Infiniti’s powertrain warranty covers the Q50 2 years and 20,000 miles longer than Audi covers the A4. Any repair needed on the engine, transmission, axles, joints or driveshafts is fully covered for 6 years or 70,000 miles. Coverage on the A4 ends after only 4 years or 50,000 miles.

Reliability Comparison

J.D. Power and Associates’ 2015 Initial Quality Study of new car owners surveyed provide the statistics that show that Infiniti vehicles are better in initial quality than Audi vehicles. J.D. Power ranks Infiniti fifth in initial quality, above the industry average. With 18 more problems per 100 vehicles, Audi is ranked 16th, below the industry average.

Regenerative brakes improve the Q50 Hybrid’s fuel efficiency by converting inertia back into energy instead of wasting it. The A4 doesn’t offer a regenerative braking system.

In heavy traffic or at stoplights the Q50 Hybrid/2.0t’s engine automatically turns off when the vehicle is stopped, saving fuel and reducing pollution. The engine is automatically restarted when the driver gets ready to move again. (Start/Stop isn’t accounted in present EPA fuel mileage tests.) The A4 doesn’t offer an automatic engine start/stop system.

The Q50 Hybrid’s standard fuel tank has 1.7 gallons more fuel capacity than the A4 (17.8 vs. 16.1 gallons), for longer range between fill-ups. The Q50’s standard fuel tank has 3.9 gallons more fuel capacity than the A4 (20 vs. 16.1 gallons).

Consumer Reports

Tires and Wheels Comparison

Changing a flat tire near traffic can be dangerous and inconvenient. The run-flat tires available on the Q50 can be driven up to 50 miles without any air pressure, allowing you to drive to a service station for a repair. The A4 doesn’t offer run-flat tires.

Suspension and Handling Comparison

The Q50 offers an optional driver-adjustable suspension system. It allows the driver to choose between an extra-supple ride, reducing fatigue on long trips, or a sport setting, which allows maximum control for tricky roads. The A4’s suspension doesn’t offer adjustable shock absorbers.

The Q50’s optional drift compensation steering can automatically compensate for road conditions which would cause the vehicle to drift from side to side, helping the driver to keep the vehicle straight more easily. The A4 doesn’t offer drift compensation steering.

For a smoother ride and more stable handling, the Q50’s wheelbase is 1.6 inches longer than on the A4 (112.2 inches vs. 110.6 inches).

The Q50 handles at .95 G’s, while the A4 2.0T Quattro pulls only .83 G’s of cornering force in a Car and Driver skidpad test.

The Q50 executes Motor Trend’s “Figure Eight” maneuver 2.1 seconds quicker than the A4 2.0T Quattro (25.5 seconds @ .76 average G’s vs. 27.6 seconds @ .62 average G’s).

For better maneuverability, the Q50’s turning circle is 1 foot tighter than the A4’s (36.7 feet vs. 37.7 feet). The Q50 AWD’s turning circle is .3 feet tighter than the A4’s (37.4 feet vs. 37.7 feet).

Chassis Comparison

The Q50 Hybrid uses computer-generated active noise cancellation to help remove annoying noise and vibration from the passenger compartment, especially at low frequencies. The A4 doesn’t offer active noise cancellation.

Passenger Space Comparison

Because it has more passenger and cargo room, the Q50 is rated a Mid-size car by the EPA, while the A4 is rated a Compact.

The Q50 has 10.9 cubic feet more passenger volume than the A4 (101.9 vs. 91).

The Q50 has 2.2 inches more front headroom, 3.2 inches more front legroom, 1.2 inches more front shoulder room and 1.8 inches more rear shoulder room than the A4.

Cargo Capacity Comparison

The Q50 has a much larger trunk than the A4 with its rear seat up (13.5 vs. 12.4 cubic feet).

Ergonomics Comparison

The Q50 Premium/Sport’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 A4 doesn’t offer an easy entry system.

If the windows are left down on the Q50 the driver can raise them all using the key in the outside lock cylinder. On a hot day the driver can lower the windows from outside the vehicle using the key in the outside lock cylinder or the keyless remote. The driver of the A4 can’t use the remote to operate the windows.

The Infiniti Intelligent Key standard on the Q50 allows you to unlock the driver’s door, trunk and start the engine all without removing a key from pocket or purse. This eliminates searching for keys before loading groceries, getting in the vehicle in bad weather or making a hurried start to your trip. The Audi A4’s available Audi Advanced Key doesn’t unlock the trunk.

While driving with high beams on, sensitive light sensors available for the Q50 Premium/Sport detect other vehicles which could be blinded and automatically switch to low beams. The A4 doesn’t offer automatic dimming high beams.

To help drivers see further while navigating curves, the Q50 Premium/Sport offers optional adaptive headlights to illuminate around corners automatically by reading vehicle speed and steering wheel angle. The A4 doesn’t offer cornering lights.

To shield the driver and front passenger’s vision over a larger portion of the windshield and side windows, the Q50 has standard extendable sun visors. The A4 doesn’t offer extendable visors.

When the Q50 Premium/Sport with available tilt-down mirrors is put in reverse, both rearview mirrors tilt from their original position. This gives the driver a better view of the curb during parallel parking maneuvers. Shifting out of reverse puts the mirrors into their original positions. The A4’s mirrors don’t automatically adjust for backing.

On extremely cold Winter days, the Q50’s optional heated steering wheel provides comfort, allowing the driver to steer safely and comfortably before the car heater warms up. The A4 doesn’t offer a heated steering wheel.

The Q50 has a standard dual zone air conditioning allows the driver and front passenger to choose two completely different temperatures so people with different temperature preferences won’t have to compromise. This makes both the driver and front passenger as comfortable as possible. Dual zone air conditioning costs extra on the A4.

To keep a safe, consistent following distance, the Q50 V6 offers an optional Intelligent Cruise Control, which alters the speed of the vehicle without driver intervention. This allows the driver to use cruise control more safely without constantly having to disengage it when approaching slower traffic. The A4 doesn’t offer an adaptive cruise control.

Standard InTouch Apps for the Q50 allows the driver and passengers access to select programs on their smartphones, including reading text messages aloud, playing internet radio stations, searching the internet and other connected activities without taking their eyes off the road or their hands from the wheel. The A4 doesn’t offer factory integrated smartphone program access.

Economic Advantages Comparison

Insurance will cost less for the Q50 owner. The Complete Car Cost Guide estimates that insurance for the Q50 will cost $195 less than the A4 over a five-year period.

Recommendations Comparison

The Infiniti Q50 won two awards in Kiplinger’s 2015 car issue. The Audi A4 only won one award.
