The Q50 Red Sport 400’s optional pre-crash front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The Sonata doesn’t offer pre-crash pretensioners.

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 Sonata 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 Sonata only offers a rear monitor.

Both the Q50 and the Sonata 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, blind spot warning systems, rearview cameras, rear cross-path warning and available all wheel drive.

Engine

The Q50’s standard 3.0 turbo V6 produces 109 more horsepower (300 vs. 191) and 114 lbs.-ft. more torque (295 vs. 181) than the Sonata’s standard 2.5 DOHC 4-cylinder. The Q50’s 3.0 turbo V6 produces 10 more horsepower (300 vs. 290) than the Sonata N Line’s standard 2.5 turbo 4-cylinder. The Q50 Red Sport 400’s standard 3.0 turbo V6 produces 110 more horsepower (400 vs. 290) and 39 lbs.-ft. more torque (350 vs. 311) than the Sonata N Line’s standard 2.5 turbo 4-cylinder.

As tested in Consumer Reports the Infiniti Q50 3.0 is faster than the Hyundai Sonata 4 cyl.:

	Q50	Sonata
Zero to 30 MPH	2.4 sec	2.9 sec
Zero to 60 MPH	5.7 sec	7.5 sec
45 to 65 MPH Passing	4.2 sec	5.2 sec
Quarter Mile	14.2 sec	15.8 sec
Speed in 1/4 Mile	103 MPH	93 MPH

Fuel Economy and Range

The Q50 has 4.1 gallons more fuel capacity than the Sonata (20 vs. 15.9 gallons), for longer range between fill-ups.

Brakes and Stopping

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

	Q50	Q50 Red Sport 400	Sonata SEL	Sonata N Line
Front Rotors	12.6 inches	14 inches	12 inches	13.6 inches
Rear Rotors	12.1 inches	13.8 inches	11.2 inches	12.8 inches

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 Sonata are solid, not vented.

The Q50 stops shorter than the Sonata:

	Q50	Sonata
60 to 0 MPH	126 feet	127 feet	Consumer Reports
60 to 0 MPH (Wet)	131 feet	138 feet	Consumer Reports

Tires and Wheels

For better traction, the Q50 has larger standard tires than the Sonata (225/50R18 vs. 215/55R17).

The Q50 Luxe’s standard tires provide better handling because they have a lower 50 series profile (height to width ratio) that provides a stiffer sidewall than the Sonata’s 55 series tires. The Q50 Red Sport 400’s 265/35R19 rear tires have a lower 35 series profile than the Sonata N Line’s 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 Sonata.

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 Sonata 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 Sonata doesn’t offer run-flat tires.

Suspension and Handling

The Q50 offers an available 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 Sonata’s suspension doesn’t offer adjustable shock absorbers.

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 Sonata doesn’t offer drift compensation steering.

Chassis

The Q50 is 3.7 inches shorter than the Sonata, making the Q50 easier to handle, maneuver and park in tight spaces.

Cargo Capacity

To allow full utilization of available cargo room, the Q50’s trunk lid uses gas strut supported hinges that don’t intrude into the trunk. Its intrusive beam hinge reduces the Sonata’s useful trunk space.

Servicing Ease

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

J.D. Power and Associates surveys of service recipients show that Infiniti service is better than Hyundai. J.D. Power ranks Infiniti 9th in service department satisfaction (above the industry average). With a 31% lower rating, Hyundai is ranked 29th.

Ergonomics

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 Sonata doesn’t offer a remote starting system.

When two different drivers share the Q50, the memory system makes it convenient for both. Each setting activates different, customized memories for the driver’s seat position, steering wheel position, outside mirror angle, climate settings and radio stations. The Sonata doesn’t offer a memory 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 Sonata doesn’t offer an easy entry system.

The Q50’s front and rear power windows all open or close fully with one touch of the switches, making it more convenient at drive-up windows and toll booths, or when talking with someone outside the car. The Sonata’s rear power window switches have to be held the entire time to open or close them fully.

If the windows are left open on the Q50 the driver can close them all at the outside door handle. On a hot day the driver can lower the windows at the outside door handle or from a distance using the keyless remote. The driver of the Sonata can only operate the windows from inside the vehicle, with the ignition on.

The Q50’s rain-sensitive wipers adjust their speed and turn on and off automatically based on the amount of rainfall on the windshield. This allows the driver to concentrate on driving without constantly adjusting the wipers. The Sonata’s intermittent wipers change speed with vehicle speed, but can’t turn on and off or change speed based on changing rainfall.

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

When the Q50 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 Sonata’s mirrors don’t automatically adjust for backing.

The Q50’s standard rear and side view mirrors have an automatic dimming feature. These mirrors can be set to automatically darken quickly when headlights shine on them, keeping following vehicles from blinding or distracting the driver. The Sonata offers an automatic rear view mirror, but its side mirrors don’t dim.

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 Sonata doesn’t offer a heated steering wheel.

Both the Q50 and the Sonata offer rear vents. For greater rear passenger comfort, the Q50 has standard rear air conditioning vents to keep rear occupants cool in summer or warm in winter. The Sonata doesn’t offer rear air conditioning vents, only heat vents.

Recommendations

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