For enhanced safety, the front and rear seat shoulder belts of the Audi A4 Allroad 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 TourX doesn’t offer pretensioners for the rear seat belts.

The A4 Allroad’s pre-crash front seatbelts will tighten automatically in the event the vehicle detects an impending crash, improving protection against injury significantly. The Regal TourX doesn’t offer pre-crash pretensioners.

Both the A4 Allroad and Regal TourX have child safety locks to prevent children from opening the rear doors. The A4 Allroad has power child safety locks, allowing the driver to activate and deactivate them from the driver's seat and to know when they're engaged. The Regal TourX’s child locks have to be individually engaged at each rear door with a manual switch. The driver can’t know the status of the locks without opening the doors and checking them.

The A4 Allroad has a standard Audi Backguard System, which use a specially designed headrest to protect the driver and front passenger from whiplash. During a rear-end collision, the Audi Backguard System moves the headrests forward to prevent neck and spine injuries. At the same time the pretensioning seatbelts fire, removing slack from the belts. The Regal TourX doesn’t offer a whiplash protection system.

The A4 Allroad has a standard Secondary Collision Brake Assist, which automatically applies the brakes in the event of a crash to help prevent secondary collisions and prevent further injuries. The Regal TourX doesn’t offer a post collision braking system: in the event of a collision that triggers the airbags, more collisions are possible without the protection of airbags that may have already deployed.

When descending a steep, off-road slope, the A4 Allroad’s standard Hill Descent Control allows you to creep down safely. The Regal TourX doesn’t offer Hill Descent Control.

The A4 Allroad Prestige has a standard Top View Camera System to allow the driver to see objects all around the vehicle on a screen. The Regal TourX 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.

Both the A4 Allroad and the Regal TourX have standard driver and passenger frontal airbags, front side-impact airbags, driver and front passenger knee airbags, side-impact head airbags, height adjustable front shoulder belts, four-wheel antilock brakes, all wheel drive, traction control, electronic stability systems to prevent skidding, daytime running lights, rearview cameras, available lane departure warning systems, blind spot warning systems and rear cross-path warning.

For its top level performance in all IIHS frontal, side, rear impact and roof-crush tests, and its standard front crash prevention system, the Insurance Institute for Highway Safety grants the A4 Allroad the rating of “Top Pick” for 2017, a rating granted to only 184 vehicles tested by the IIHS. The Regal TourX has not been tested, yet.

For better traction, the A4 Allroad has larger tires than the Regal TourX (245/45R18 vs. 235/50R18).

The A4 Allroad’s tires provide better handling because they have a lower 45 series profile (height to width ratio) that provides a stiffer sidewall than the Regal TourX’s standard 50 series tires.

The A4 Allroad has a standard space-saver spare tire so you can replace a flat tire and drive to have the flat repaired or replaced. A spare tire isn’t available on the Regal TourX; it requires you to depend on roadside assistance and your vehicle will have to be towed.

The A4 Allroad has a standard 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 Regal TourX’s suspension doesn’t offer adjustable shock absorbers.

The A4 Allroad Prestige has a standard 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 Regal TourX doesn’t offer a heads-up display.

The A4 Allroad’s 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 TourX’s rear power window switches have to be held the entire time to close them fully.

If the windows are left open on the A4 Allroad 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 TourX can only operate the windows from inside the vehicle, with the ignition on.

The A4 Allroad’s 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 TourX’s manually variable intermittent wipers have to be constantly adjusted.

Heated windshield washer nozzles are standard on the A4 Allroad to prevent washer fluid and nozzles from freezing and help continue to keep the windshield clear in sub-freezing temperatures. The Regal TourX doesn’t offer heated windshield washer nozzles.

In poor weather, headlights can lose their effectiveness as grime builds up on their lenses. This can reduce visibility without the driver realizing. The A4 Allroad Prestige has standard headlight washers to keep headlight output high. The Regal TourX doesn’t offer headlight washers.

While driving with high beams on, sensitive light sensors standard on the A4 Allroad detect other vehicles which could be blinded and automatically switch to low beams. The Regal TourX doesn’t offer automatic dimming high beams.

To shield the driver and front passenger’s vision over a larger portion of the windshield and side windows, the A4 Allroad has standard extendable sun visors. The Regal TourX doesn’t offer extendable visors.

The A4 Allroad has standard heated front seats. Heated front seats are only available on the Regal TourX Essence. The A4 Allroad Premium Plus/Prestige also offers optional heated rear seats to keep those passengers extremely comfortable in the winter. Heated rear seats aren’t available in the Regal TourX.

Optional air-conditioned seats in the A4 Allroad Premium Plus/Prestige keep the driver and front passenger comfortable and take the sting out of hot seats in summer. The Regal TourX doesn’t offer air-conditioned seats.

The A4 Allroad Prestige’s Park Steering Assist can parallel park or back into a parking spot by itself, with the driver only controlling speed with the brake pedal. The Regal TourX doesn’t offer an automated parking system.
