Compare the2024 Infiniti Q50VS 2024 Audi A3

Over 200 people are killed each year when backed over by motor vehicles. The Q50 has standard Back-up Collision Intervention that uses rear sensors to monitor for objects to the rear and automatically applies the brakes to prevent a collision. The A3 doesn’t offer automatic braking for stationary objects directly to the rear.

The Q50 has a standard Around View® Monitor to allow the driver to see objects all around the vehicle on a screen. The A3 only offers a rear monitor and front and rear parking sensors that beep or flash a light. That doesn’t help with obstacles to the sides.

The Q50 has a standard blind spot warning system that uses sensors to alert the driver to objects in the vehicle’s blind spots where the side view mirrors don’t reveal them and moves the vehicle back into its lane. A system to reveal vehicles in the A3’s blind spot costs extra.

To help make backing out of a parking space safer, the Q50 has standard Rear Cross Traffic Alert and Back-up Collision Intervention automatically engages the brakes to help avoid a collision. Audi charges extra for Rear Cross-Traffic Assist on the A3.

Both the Q50 and the A3 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, crash mitigating brakes, daytime running lights, lane departure warning systems, rearview cameras and available all wheel drive.

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 A3’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 A3. Any repair needed on the engine, transmission, axles, joints or driveshafts is fully covered for 6 years or 70,000 miles. Coverage on the A3 ends after only 4 years or 50,000 miles.

Infiniti pays for scheduled maintenance on the Q50 for 3 years and 36,000 miles. Infiniti will pay for oil changes, tire rotations, air filter replacements, cabin filter replacement, brake fluid replacement, inspections, and any other required maintenance. Audi only pays for the first scheduled maintenance visit on the A3.

J.D. Power and Associates’ 2023 Initial Quality Study of new car owners surveyed provide the statistics that show that Infiniti vehicles are better in initial quality than Audi vehicles. With 9 fewer problems per 100 vehicles, JD Power ranks Infiniti higher than Audi.

J.D. Power and Associates’ 2022 survey of the owners of three-year-old vehicles provides the long-term dependability statistics that show that Infiniti vehicles are more reliable than Audi With 4 fewer problems per 100 vehicles in the first three years of ownership, J.D. Power ranks Infiniti higher than Audi.

From surveys of all its subscribers, Consumer Reports’ January 2024 Auto Issue reports that Infiniti vehicles are more reliable than Audi vehicles. Consumer Reports ranks Infiniti 6 places higher in reliability than Audi.

The Q50’s standard 3.0 turbo V6 produces 99 more horsepower (300 vs. 201) and 74 lbs.-ft. more torque (295 vs. 221) than the A3’s 2.0 turbo 4-cylinder hybrid. The Q50 Red Sport 400’s standard 3.0 turbo V6 produces 199 more horsepower (400 vs. 201) and 129 lbs.-ft. more torque (350 vs. 221) than the A3’s 2.0 turbo 4-cylinder hybrid.

As tested in Consumer Reports the Infiniti Q50 3.0 is faster than the Audi A3:

The Q50 has 5.5 gallons more fuel capacity than the A3 (20 vs. 14.5 gallons), for longer range between fill-ups.

For better stopping power the Q50’s brake rotors are larger than those on the A3:

The Q50’s standard front and rear disc brakes are vented to help dissipate heat for shorter stops with less fading. The rear discs on the A3 are solid, not vented.

The Q50 stops much shorter than the A3:

For better traction, the Q50 Red Sport 400’s tires are larger than the largest tires available on the A3 (F:245/40R19 & R:265/35R19 vs. 225/45R17).

The Q50 Red Sport 400’s 265/35R19 rear tires provide better handling because they have a lower 35 series profile (height to width ratio) that provides a stiffer sidewall than the A3’s optional 40 series tires.

For better ride, handling and brake cooling the Q50 Luxe has standard 18-inch wheels. Smaller 17-inch wheels are standard on the A3. The Q50 Sensory/Red Sport 400 AWD’s 19-inch wheels are larger than the 18-inch wheels optional on the A3.

The Q50 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 A3 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 Q50 can be driven up to 50 miles without any air pressure, allowing you to drive to a service station for a repair. The A3 doesn’t offer run-flat tires.

The Q50 Sport’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 A3 doesn’t offer drift compensation steering.

For a smoother ride and more stable handling, the Q50’s wheelbase is 8.7 inches longer than on the A3 (112.2 inches vs. 103.5 inches).

For better handling and stability, the average track (width between the wheels) on the Q50 is 1.9 inches wider in the rear than the track on the A3.

Because it has more passenger and cargo room, the EPA rates the Q50 a Mid-size car, while the A3 is rated a Subcompact.

The Q50 has 13 cubic feet more passenger volume than the A3 (100 vs. 87).

The Q50 has 2.7 inches more front headroom, 3.3 inches more front legroom, 1.9 inches more front shoulder room, .2 inches more rear headroom and 3.1 inches more rear shoulder room than the A3.

The Q50 has a much larger trunk than the A3 (13.5 vs. 10.9 cubic feet).

With its sedan body style, valet key, locking rear seatbacks and remote trunk release lockout, the Q50 offers cargo security. The A3’s non-lockable folding seat and non-lockable remote release defeat cargo security.

The engine in the Q50 is mounted longitudinally (North-South), instead of sideways, as in the A3. This makes it easier to service and maintain, because the accessory belts are in front.

The Q50 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 A3 doesn’t offer a remote starting system.

The Q50’s standard Entry/Exit Assist raises the steering wheel and glides the driver’s seat back, making it easier for the driver to get in and out. The A3 doesn’t offer an easy entry system.

Consumer Reports rated the Q50’s headlight performance “Good,” a higher rating than the A3’s headlights, which were rated “Fair.”

To help drivers see further while navigating curves, the Q50 Red Sport 400 offers optional adaptive headlights to illuminate around corners automatically by reading vehicle speed and steering wheel angle. The A3 doesn’t offer cornering lights.

The Q50’s sun-visors swivel front-to-side to block glare from the side windows. The A3’s visors are fixed into the windshield header.

On extremely cold winter days, the Q50’s standard heated steering wheel provides comfort, allowing the driver to steer safely and comfortably before the car heater warms up. The A3 doesn’t offer a heated steering wheel.

Consumer Reports® recommends both the Infiniti Q50 and the Audi A3, based on reliability, safety and performance.
