Safety

The Mazda 3 has standard Whiplash Reducing Headrests, which use a specially designed headrest to protect the driver and front passenger from whiplash. During a rear-end collision, the Whiplash Reducing Headrests system moves the headrests forward to prevent neck and spine injuries. The Regal TourX doesn’t offer a whiplash protection system.

Over 200 people are killed each year when backed over by motor vehicles. The Mazda 3 offers optional Rear Smart Brake Support that uses rear sensors to monitor and automatically apply the brakes to prevent a rear collision. The Regal TourX doesn’t offer backup collision prevention brakes.

The Mazda 3 offers an optional 360-Degree Monitor 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.

The Mazda 3 =’s 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 TourX doesn’t offer a driver alert monitor.

Both the Mazda 3 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, front seatbelt pretensioners, height adjustable front shoulder belts, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, daytime running lights, rearview cameras, available all wheel drive, crash mitigating brakes, lane departure warning systems, blind spot warning systems and rear cross-path warning.

An engine control system that can shut down half of the engine’s cylinders helps improve the Mazda 3 Premium/Hatchback/AWD’s fuel efficiency. The Regal TourX doesn’t offer a system that can shut down part of the engine.

To lower fuel costs and make buying fuel easier, the Mazda 3 uses regular unleaded gasoline. The Regal TourX requires premium for maximum efficiency, which can cost 20 to 55 cents more per gallon.

Transmission

The Mazda 3 offers a manual transmission for better acceleration, control and fuel economy. The Regal TourX doesn’t offer a manual transmission.

Tires and Wheels

The Mazda 3’s optional 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 50 series tires.

The Mazda 3 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.

Suspension and Handling

For better maneuverability, the Mazda 3’s turning circle is 5.2 feet tighter than the Regal TourX’s (34.8 feet vs. 40 feet).

Chassis

The Mazda 3 may be more efficient, handle and accelerate better because it weighs about 600 to 700 pounds less than the Buick Regal TourX.

The Mazda 3 Hatchback is 1 foot, 8.7 inches shorter than the Regal TourX, making the Mazda 3 easier to handle, maneuver and park in tight spaces.

Ergonomics

The Mazda 3 Premium has a standard heads-up display that projects speed and warning light 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 Mazda 3’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.

The Mazda 3 Hatchback/Select/Preferred/Premium’s standard wipers adjust their speed and turn on and off automatically according to the amount of rainfall on the windshield. The Regal TourX’s manually variable intermittent wipers have to be constantly adjusted.

While driving with high beams on, sensitive light sensors standard on the Mazda 3 (except Base Sedan) detect other vehicles which could be blinded and automatically switch to low beams. The Regal TourX doesn’t offer automatic dimming high beams.

The Regal TourX Preferred/Essence’s optional cornering lamps activate a lamp on the front corner when the turn signal is activated. The Mazda 3 Premium’s standard 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.

To shield the driver and front passenger’s vision over a larger portion of the windshield and side windows, the Mazda 3 has standard extendable sun visors. The Regal TourX doesn’t offer extendable visors.

Model Availability

The Mazda 3 is available in both front-wheel drive and all-wheel drive configurations. The Regal TourX doesn’t offer a two-wheel drive configuration.

Recommendations

The Mazda 3 outsold the Buick Regal by almost five to one during 2018.
