The TLX offers all-wheel drive to maximize traction under poor conditions, especially in ice and snow. The Sonata doesn’t offer all-wheel drive.

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 seatbelt pretensioners, 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, rearview cameras, available blind spot warning systems, around view monitors and rear cross-path warning.

The TLX’s standard 2.4 DOHC 4-cylinder produces 26 more horsepower (206 vs. 180) than the Sonata SEL Plus/Limited’s standard 1.6 turbo 4-cylinder. The TLX’s 2.4 DOHC 4-cylinder produces 15 more horsepower (206 vs. 191) and 1 lbs.-ft. more torque (182 vs. 181) than the Sonata’s standard 2.5 DOHC 4-cylinder. The TLX’s optional 3.5 SOHC V6 produces 99 more horsepower (290 vs. 191) and 86 lbs.-ft. more torque (267 vs. 181) than the Sonata’s standard 2.5 DOHC 4-cylinder.

An engine control system that can shut down some of the engine’s cylinders helps improve the TLX V6’s fuel efficiency. The Sonata doesn’t offer a system that can shut down part of the engine.

The TLX has 1.3 gallons more fuel capacity than the Sonata (17.2 vs. 15.9 gallons), for longer range between fill-ups.

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.

A nine-speed automatic is standard on the Acura TLX V6, for better acceleration and lower engine speed on the highway. Only an eight-speed automatic is available for the Sonata.

The TLX offers a standard sequential manual gearbox (SMG). With no clutch pedal to worry about and a fully automatic mode, an SMG is much more efficient than a conventional automatic but just as easy to drive. The Sonata doesn’t offer an SMG or a conventional manual transmission.

For better traction, the TLX has larger standard tires than the Sonata (225/55R17 vs. 205/65R16). The TLX A-Spec’s tires are larger than the largest tires available on the Sonata (245/40R19 vs. 235/45R18).

The TLX’s standard tires provide better handling because they have a lower 55 series profile (height to width ratio) that provides a stiffer sidewall than the Sonata SE’s standard 65 series tires. The TLX A-Spec’s tires have a lower 40 series profile than the Sonata SEL Plus/Limited’s 45 series tires.

For better ride, handling and brake cooling the TLX has standard 17-inch wheels. Smaller 16-inch wheels are standard on the Sonata SE. The TLX A-Spec’s 19-inch wheels are larger than the 18-inch wheels on the Sonata SEL Plus/Limited.

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.

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.

As tested by Car and Driver while under full throttle, the interior of the TLX V6 SH-AWD is quieter than the Sonata Limited (74 vs. 78 dB).

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

With its sedan body style, valet key, locking rear seatbacks and remote trunk release lockout, the TLX offers cargo security. The Sonata’s non-lockable remote release defeats cargo security.

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 standard passenger windows don’t open or close automatically. With the Sonata SEL/SEL Plus/Limited’s power windows, only the front windows open or close automatically.

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’s standard outside mirrors include heating elements to clear off the mirrors for better visibility. Hyundai only offers heated mirrors on the Sonata SEL/SEL Plus/Limited.

The TLX’s standard rear view mirror and optional 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.

The TLX has standard heated front seats. Heated front seats are only available on the Sonata SEL/SEL Plus/Limited. The TLX Advance also has standard heated rear seats to keep those passengers extremely comfortable in the winter. Heated rear seats aren’t available in the Sonata.

The TLX 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 is only available on the Sonata SEL/SEL Plus/Limited.

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.
