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 Kia Stinger 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 Stinger doesn’t offer pre-crash pretensioners.

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

In its Green Vehicle Guide, the U.S. Environmental Protection Agency (EPA) rates the Mercedes A-Class higher (5 out of 10) than the Kia Stinger (3). This means the A-Class produces up to 16.5 pounds less smog-producing pollutants than the Stinger every 15,000 miles.

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 Stinger doesn’t offer an SMG or a conventional manual transmission.

In an emergency stopping situation, many drivers don’t press the brakes with enough force to stop the vehicle in the shortest distance. The A-Class has a standard brake assist system to detect emergency braking situations (by how hard and how quickly the brake pedal is pressed) and then automatically apply maximum braking immediately in order to help prevent a collision. The Stinger doesn’t offer a brake assist feature.

The A-Class stops much shorter than the Stinger:

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 Stinger doesn’t offer run-flat tires.

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 Stinger doesn’t offer drift compensation steering.

The A 220 4MATIC handles at .95 G’s, while the Stinger AWD pulls only .88 G’s of cornering force in a Car and Driver skidpad test.

For better maneuverability, the A-Class’ turning circle is .6 feet tighter than the Stinger’s (36.1 feet vs. 36.7 feet). The A-Class’ turning circle is 2.3 feet tighter than the Stinger AWD’s (36.1 feet vs. 38.4 feet).

The Mercedes A-Class may be more efficient, handle and accelerate better because it weighs about 350 to 650 pounds less than the Kia Stinger.

The A-Class is 11.1 inches shorter than the Stinger, making the A-Class easier to handle, maneuver and park in tight spaces.

The design of the Mercedes A-Class amounts to more than styling. The A-Class has an aerodynamic coefficient of drag of .27 Cd. That is lower than the Stinger (.3) and many sports cars. A more efficient exterior helps keep the interior quieter and helps the A-Class get better fuel mileage.

Unlike the driver-only memory system in the Stinger GT1/GT2, 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’ power parking brake sets with one touch and releases with one touch or automatically. The Stinger’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 Stinger’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 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 Stinger can only operate the windows from inside the vehicle, with the ignition on.

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 Stinger’s standard manually variable intermittent wipers have to be constantly adjusted.

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 Stinger doesn’t offer an automated parking system.
