Safety

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 seatbelt pretensioners, 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.

Car and Driver

Tires and Wheels

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.

Suspension and Handling

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).

Chassis

The Mercedes A-Class may be more efficient, handle and accelerate better because it weighs about 450 to 850 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.

Cargo Capacity

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.

Servicing Ease

J.D. Power and Associates surveys of service recipients show that Mercedes service is better than Buick. J.D. Power ranks Mercedes 6th in service department satisfaction (above the industry average). With a 18% lower rating, Buick is ranked 9th.

Ergonomics

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’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 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 costs extra on the Regal Sportback.

The A-Class’ optional Active Parking Assist can parallel park or back into a parking spot by itself, with the driver only controlling speed with the brake pedal. The Regal Sportback doesn’t offer an automated parking system.
