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 Buick Regal Sportback 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 Regal Sportback doesn’t offer pre-crash pretensioners.

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

Both the A-Class and the Regal Sportback have standard driver and passenger frontal airbags, front and rear side-impact airbags, driver and front passenger 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 all-wheel drive, lane departure warning systems and blind spot warning systems.

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

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 Regal Sportback 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 Regal Sportback doesn’t offer drift compensation steering.

The A 220 4MATIC handles at .95 G’s, while the Regal Sportback GS pulls only .87 G’s of cornering force in a Car and Driver skidpad test.

For better maneuverability, the A-Class’ turning circle is 2.9 feet tighter than the Regal Sportback’s (36.1 feet vs. 39 feet). The A-Class’ turning circle is 4.9 feet tighter than the Regal Sportback’s (36.1 feet vs. 41 feet).

The Mercedes A-Class may be more efficient, handle and accelerate better because it weighs about 450 to 900 pounds less than the Buick Regal Sportback.

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

A standard locking glovebox (which can’t be accessed with the valet key) keeps your small valuables safer in the A-Class. The Regal Sportback doesn’t offer locking storage for small valuables.

To make loading groceries and cargo easier when your hands are full, the A-Class’ available trunk can be opened just by kicking your foot under the back bumper, leaving your hands completely free. The Regal Sportback doesn’t offer a hands-free gesture to open its liftgate, forcing you to put cargo down if your hands are full.

The A-Class’ standard easy entry system glides the driver’s seat back, making it easier for the driver to get in and out. An easy entry system costs extra on the Regal Sportback, and is not available on all models.

The A-Class’ front and rear power windows all open or close with one touch of the switches, making it more convenient at drive-up windows and toll booths, or when talking with someone outside of the car. The Regal Sportback’s rear power window switches have to be held the entire time to 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 Regal Sportback 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 Regal Sportback’s manually variable intermittent wipers have to be constantly adjusted.

While driving with high beams on, sensitive light sensors available for the A-Class detect other vehicles which could be blinded and automatically switch to low beams. The Regal Sportback doesn’t offer automatic dimming high beams.

The Regal Sportback (except Base)’s optional cornering lamps activate a lamp on the front corner when the turn signal is activated. The A-Class’ optional adaptive cornering lights turn the actual headlight unit up to several degrees, depending on steering wheel angle and vehicle speed. This lights a significant distance into corners at any speed.

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 Regal Sportback doesn’t offer an automated parking system.
