For enhanced safety, the front and rear seat shoulder belts of the Mercedes A-Class 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 the rear seat belts.

The A-Class’ 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.

The A-Class 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 A-Class and the Sonata have standard driver and passenger frontal airbags, front and rear side-impact airbags, driver knee airbags, side-impact head airbags, front-wheel drive, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, rearview cameras, driver alert monitors, available lane departure warning systems, blind spot warning systems and around view monitors.

The A-Class’ 2.0 turbo 4-cylinder produces 8 more horsepower (188 vs. 180) and 26 lbs.-ft. more torque (221 vs. 195) than the Sonata SEL Plus/Limited’s standard 1.6 turbo 4-cylinder. The A-Class’ 2.0 turbo 4-cylinder produces 40 lbs.-ft. more torque (221 vs. 181) than the Sonata’s standard 2.5 DOHC 4-cylinder.

The A-Class 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.

The A-Class’ 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 A-Class’ optional 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 A-Class has standard 17-inch wheels. Smaller 16-inch wheels are standard on the Sonata SE. The A-Class’ optional 19-inch wheels are larger than the 18-inch wheels on the Sonata SEL Plus/Limited.

Changing a flat tire near traffic can be dangerous and inconvenient. The run-flat tires available on the A-Class 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.

The A-Class 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 Sonata’s suspension doesn’t offer adjustable shock absorbers.

The A-Class’ 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.

The A 220 4MATIC handles at .95 G’s, while the Sonata Limited pulls only .89 G’s of cornering force in a Car and Driver skidpad test.

The A-Class is 1 foot, 1.8 inches shorter than the Sonata, making the A-Class easier to handle, maneuver and park in tight spaces.

To allow full utilization of available cargo room, the A-Class’ 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.

Unlike the driver-only memory system in the Sonata Limited, the A-Class has standard driver and passenger memory, so that when drivers switch, the memory setting adjusts the driver’s seat and outside mirror angle and the front passenger seat also adjusts to the new passenger’s preset preferences.

The A-Class’ 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 A-Class the driver can close them all at the outside door handle or from a distance using the remote. On a hot day the driver can lower the windows 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.

To help drivers avoid possible obstacles, the A-Class offers optional cornering lights to illuminate around corners when the turn signals are activated. The Sonata doesn’t offer cornering lights. The A-Class also offers optional adaptive headlights to illuminate around corners automatically by reading vehicle speed and steering wheel angle.

The A-Class’ 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 A-Class offers optional automatic dimming rear and side view mirrors which 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 A-Class 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 A-Class and the Sonata offer rear vents. For greater rear passenger comfort, the A-Class 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.
