For enhanced safety, the front and rear seat shoulder belts of the Acura TLX have pretensioners to tighten the seatbelts and eliminate dangerous slack in the event of a collision and force limiters to limit the pressure the belts will exert on the passengers. The Hyundai Sonata doesn’t offer pretensioners for its rear seat belts.

The Acura TLX has standard driver and front passenger side knee airbags mounted low on the dashboard. These airbags helps prevent the driver and front passenger from sliding under their seatbelts or the main frontal airbags; this keeps them better positioned during a collision for maximum protection. Knee airbags also help keep the legs from striking the dashboard, preventing knee and leg injuries in the case of a serious frontal collision. The Sonata doesn’t offer a front passenger side knee airbag.

The TLX Type S has a standard Surround View Camera System to allow the driver to see objects all around the vehicle on a screen. The Sonata only offers a rear monitor.

Both the TLX and the Sonata have standard driver and passenger frontal airbags, front side-impact airbags, driver knee airbags, side-impact head airbags, front wheel drive, 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, driver alert monitors and available all wheel drive.

For its top level performance in IIHS driver and passenger-side small overlap frontal, moderate overlap frontal, side impact, roof strength and head restraint tests, its standard vehicle-to-vehicle front crash prevention system, its standard vehicle-to-pedestrian front crash prevention system, and its standard headlight’s “Good” rating, the Insurance Institute for Highway Safety grants the TLX its highest rating: “Top Safety Pick Plus” for 2022, a rating granted to only 129 vehicles tested by the IIHS. The Sonata has not been tested, yet.

Reliability

A reliable vehicle saves its owner time, money and trouble. Nobody wants to be stranded or have to be without a vehicle while it’s being repaired. Consumer Reports rates the TLX’s reliability 22 points higher than the Sonata.

From surveys of all its subscribers, Consumer Reports’ January 2024 Auto Issue reports that Acura vehicles are more reliable than Hyundai vehicles. Consumer Reports ranks Acura fourth in overall reliability. Hyundai is ranked 11th.

Engine

The TLX’s standard 2.0 turbo 4-cylinder produces 81 more horsepower (272 vs. 191) and 99 lbs.-ft. more torque (280 vs. 181) than the Sonata’s standard 2.5 DOHC 4-cylinder. The TLX Type S’ standard 3.0 turbo V6 produces 65 more horsepower (355 vs. 290) and 43 lbs.-ft. more torque (354 vs. 311) than the Sonata N Line’s standard 2.5 turbo 4-cylinder.

As tested in Consumer Reports the Acura TLX turbo 4 cyl. is faster than the Hyundai Sonata 4 cyl.:

	TLX	Sonata
Zero to 60 MPH	6.5 sec	7.5 sec
45 to 65 MPH Passing	4.2 sec	5.2 sec
Quarter Mile	15.1 sec	15.8 sec
Speed in 1/4 Mile	98 MPH	93 MPH

Fuel Economy and Range

An engine control system that can shut down some of the engine’s cylinders helps improve the TLX Type S’ fuel efficiency. The Sonata doesn’t offer a system that can shut down part of the engine.

In heavy traffic or at stoplights the TLX’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. If the conditions warrant or the driver wishes, the system can be manually disabled at any time for the duration of a trip. The Sonata doesn’t offer an automatic engine start/stop system.

The TLX has a standard cap-less fueling system. The fuel filler is automatically opened when the fuel nozzle is inserted and automatically closed when it’s removed. This eliminates the need to unscrew and replace the cap and it reduces fuel evaporation, which causes pollution. The Sonata doesn’t offer a cap-less fueling system.

Transmission

A 10-speed automatic is standard on the Acura TLX, for better acceleration and lower engine speed on the highway. Only an eight-speed automatic is available for the Sonata.

Brakes and Stopping

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

	TLX	TLX Type S	Sonata SEL	Sonata N Line
Front Rotors	13 inches	14.3 inches	12 inches	13.6 inches
Rear Rotors	13 inches	13 inches	11.2 inches	12.8 inches

Tires and Wheels

For better traction, the TLX has larger tires than the Sonata (255/35R20 vs. 215/55R17). The TLX Type S’ tires are larger than the largest tires available on the Sonata (255/35R20 vs. 245/40R19).

The TLX’s standard tires provide better handling because they have a lower 40 series profile (height to width ratio) that provides a stiffer sidewall than the Sonata’s 55 series tires. The TLX Type S’ tires have a lower 35 series profile than the Sonata N Line’s 40 series tires.

For better ride, handling and brake cooling the TLX has standard 19-inch wheels. Smaller 17-inch wheels are standard on the Sonata. The TLX Type S’ 20-inch wheels are larger than the 19-inch wheels on the Sonata N Line.

The TLX 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.

Suspension and Handling

The TLX 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.

For a smoother ride and more stable handling, the TLX’s wheelbase is 1.2 inches longer than on the Sonata (113 inches vs. 111.8 inches).

Chassis

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

Passenger Space

The TLX has 1.2 inches more front hip room, .3 inches more front shoulder room, .1 inches more rear legroom and .2 inches more rear hip room than the Sonata.

Cargo Capacity

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

Servicing Ease

J.D. Power and Associates surveys of service recipients show that Acura service is better than Hyundai. J.D. Power ranks Acura 6th in service department satisfaction (above the industry average). With a 40% lower rating, Hyundai is ranked 29th.

Ergonomics

The TLX 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 Sonata doesn’t offer a remote starting system.

When two different drivers share the TLX, the memory seats and mirrors make it convenient for both. Each setting activates different, customized memories for the driver’s seat position and outside mirror angle. The Sonata doesn’t offer a memory system.

The TLX’s standard easy entry system 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 TLX Type S has a standard heads-up display that projects speed, warning and navigation instruction readouts in front of the driver’s line of sight, allowing drivers to view information without diverting their eyes from the road. The Sonata doesn’t offer a heads-up display.

The TLX’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 TLX 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 TLX Type S’ standard wipers adjust their speed and turn on and off automatically according to the amount of rainfall on the windshield. 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 TLX’s headlight performance “Good,” a higher rating than the Sonata’s headlights, which were rated “Fair.”

When the TLX 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.

Standard air-conditioned seats in the TLX A-Spec/Type S keep the driver and front passenger comfortable and take the sting out of hot seats in Summer. The Sonata doesn’t offer air-conditioned seats.

On extremely cold winter days, the TLX’s optional 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 TLX and the Sonata offer rear vents. For greater rear passenger comfort, the TLX 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.

To quickly and conveniently keep personal devices charged without cables tangling and wearing out, the Acura TLX has a standard wireless phone charging system (Qi) in the center console. Wireless charging costs extra on the Sonata.
