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 Ioniq Hybrid 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 Ioniq Hybrid doesn’t offer backup collision prevention brakes.

The Mazda 3 offers all-wheel drive to maximize traction under poor conditions, especially in ice and snow. The Ioniq Hybrid doesn’t offer all-wheel drive.

The Mazda 3 offers an optional 360-Degree Monitor to allow the driver to see objects all around the vehicle on a screen. The Ioniq Hybrid 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 Mazda 3 and the Ioniq Hybrid have standard driver and passenger frontal airbags, front side-impact airbags, driver knee airbags, side-impact head airbags, front seatbelt pretensioners, front wheel drive, height adjustable front shoulder belts, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, rearview cameras, available crash mitigating brakes, lane departure warning systems, blind spot warning systems, rear cross-path warning and driver alert monitors.

Reliability

From surveys of all its subscribers, Consumer Reports’ December 2018 Auto Issue reports that Mazda vehicles are more reliable than Hyundai vehicles. Consumer Reports ranks Mazda third in reliability. Hyundai is ranked 10th.

Engine

The Mazda 3’s 2.5 DOHC 4 cyl. produces 47 more horsepower (186 vs. 139) than the Ioniq Hybrid’s 1.6 DOHC 4 cyl. hybrid.

Fuel Economy and Range

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 Ioniq Hybrid doesn’t offer a system that can shut down part of the engine.

The Mazda 3 FWD’s standard fuel tank has 1.3 gallons more fuel capacity than the Ioniq Hybrid (13.2 vs. 11.9 gallons).

Brakes and Stopping

For better stopping power the Mazda 3 AWD’s brake rotors are larger than those on the Ioniq Hybrid:

Tires and Wheels

For better traction, the Mazda 3 has larger standard tires than the Ioniq Hybrid (205/60R16 vs. 195/65R15).

The Mazda 3 Sedan’s standard tires provide better handling because they have a lower 60 series profile (height to width ratio) that provides a stiffer sidewall than the Ioniq Hybrid’s standard 65 series tires.

For better ride, handling and brake cooling the Mazda 3 Sedan has standard 16-inch wheels. Smaller 15-inch wheels are standard on the Ioniq Hybrid. The Mazda 3’s optional 18-inch wheels are larger than the 17-inch wheels optional on the Ioniq Hybrid Limited.

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 Ioniq Hybrid; it requires you to depend on roadside assistance and your vehicle will have to be towed.

Passenger Space

The Mazda 3 Sedan has .1 inches more front legroom and .8 inches more front hip room than the Ioniq Hybrid.

Ergonomics

The Mazda 3 Auto offers a remote vehicle starting system, so the vehicle can be started from inside the driver's house. This allows the driver to comfortably warm up the engine before going out to the vehicle. The Ioniq Hybrid doesn’t offer a remote starting system.

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 Ioniq Hybrid doesn’t offer a heads-up display.

The Mazda 3’s 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 Ioniq Hybrid’s standard passenger windows don’t open or close automatically. With the Ioniq Hybrid Limited’s power windows, only the front windows open or close automatically.

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 Ioniq Hybrid’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 Ioniq Hybrid doesn’t offer automatic dimming high beams.

When the Mazda 3 Preferred/Premium is put in reverse, both rearview mirrors tilt from their original position. This gives the driver a better view of the curb during parallel parking maneuvers. Shifting out of reverse puts the mirrors into their original positions. The Ioniq Hybrid’s mirrors don’t automatically adjust for backing.

The Mazda 3 offers optional automatic dimming rear and side view mirrors which automatically darken quickly when headlights shine on them, keeping following vehicles from blinding or distracting the driver. The Ioniq Hybrid offers an automatic rear view mirror, but its side mirrors don’t dim.

Model Availability

The Mazda 3 comes in sedan and four door hatchback bodystyles; the Hyundai Ioniq Hybrid isn’t available as a sedan.

Recommendations

The Mazda 3 outsold the Hyundai Ioniq by over four to one during 2018.
