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.

The A-Class offers an optional Surround View System to allow the driver to see objects all around the vehicle on a screen. The Sonata only offers a rear monitor and rear parking sensors that beep or flash a light. That doesn’t help with obstacles to the front or sides.

The A-Class’ driver alert monitor detects an inattentive driver then sounds a warning and suggests a break. According to the NHTSA, drivers who fall asleep cause about 100,000 crashes and 1500 deaths a year. The Sonata doesn’t offer a driver alert monitor.

Both the A-Class and the Sonata have standard driver and passenger frontal airbags, front 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, daytime running lights, rearview cameras, available lane departure warning systems and blind spot warning systems.

The A-Class’ 2.0 turbo 4-cylinder produces 10 more horsepower (188 vs. 178) and 26 lbs.-ft. more torque (221 vs. 195) than the Sonata Eco’s standard 1.6 turbo 4-cylinder. The A-Class’ 2.0 turbo 4-cylinder produces 3 more horsepower (188 vs. 185) and 43 lbs.-ft. more torque (221 vs. 178) than the Sonata’s standard 2.4 DOHC 4-cylinder.

On the EPA test cycle the A 220 FWD Auto gets better fuel mileage than the Sonata Limited 2.0T 2.0 turbo 4 cyl. (24 city/35 hwy vs. 23 city/32 hwy).

In heavy traffic or at stoplights the A-Class’ 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. (Start/Stop isn’t accounted in present EPA fuel mileage tests.) The Sonata doesn’t offer an automatic engine start/stop system.

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/Eco’s standard 65 series tires. The A-Class’ optional tires have a lower 40 series profile than the Sonata 2.0T’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/Eco. The A-Class’ optional 19-inch wheels are larger than the 18-inch wheels on the Sonata 2.0T.

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 pulls only .80 G’s of cornering force in a Car and Driver skidpad test.

The A 220 executes Motor Trend’s “Figure Eight” maneuver 1.6 seconds quicker than the Sonata Eco (26.5 seconds @ .68 average G’s vs. 28.1 seconds @ .58 average G’s).

The A-Class is 12 inches shorter than the Sonata, making the A-Class easier to handle, maneuver and park in tight spaces.

A low lift-over trunk design makes loading and unloading the A-Class easier. The A-Class’ trunk lift-over height is 26.1 inches, while the Sonata’s liftover is 28.6 inches.

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.

The A-Class 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.

Unlike the driver-only memory seat and mirrors 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 offers an optional heads-up display that projects speed and other key instrumentation 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 A-Class’ power parking brake sets with one touch and releases with one touch or automatically. The Sonata’s parking brake has to released manually.

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/Sport/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.

The A-Class’ power window, power lock, power mirror and cruise control switches are lit from behind, making them plainly visible and easier to operate at night. The Sonata’s power mirror switches are unlit, making them difficult to find at night and operate safely.

The A-Class’ 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 manually variable intermittent wipers have to be constantly adjusted.

When the A-Class is put in reverse, the passenger rearview mirror tilts from its original position. This gives the driver a better view of the curb during parallel parking maneuvers. Shifting out of reverse puts the mirror into its original position. The Sonata’s mirror doesn’t automatically adjust for backing.

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/Sport/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.

The A-Class’ optional Active Parking Assist can parallel park or back into a parking spot by itself, starting, stopping and changing direction automatically. The Sonata doesn’t offer an automated parking system.
