Both the K5 and Corolla have child safety locks to prevent children from opening the rear doors. The K5 EX/GT offers optional 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 Corolla’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.

In the past twenty years hundreds of infants and young children have died after being left in vehicles, usually by accident. When turning the vehicle off, drivers of the K5 are reminded to check the back seat if they opened the rear door before starting out. The Corolla doesn’t offer a back seat reminder.

Over 200 people are killed each year when backed over by motor vehicles. The K5 EX/GT offers optional Parking Collision Assist that uses rear sensors to monitor and automatically apply the brakes to prevent a rear collision. The Corolla doesn’t offer backup collision prevention brakes.

The K5 1.6T offers all-wheel drive to maximize traction under poor conditions, especially in ice and snow. The Corolla doesn’t offer all-wheel drive.

The K5 EX/GT offers an optional Surround View Monitor to allow the driver to see objects all around the vehicle on a screen. The Corolla only offers a rear monitor.

The K5 has a standard blind spot warning system which uses sensors to alert the driver to objects in the vehicle’s blind spots where the side view mirrors don’t reveal them and moves the vehicle back into its lane. A system to reveal vehicles in the Corolla’s blind spot costs extra.

To help make backing out of a parking space safer, the K5 has a standard rear cross-path warning system, which uses sensors in the rear bumper to alert the driver to vehicles approaching from the side, helping the driver avoid collisions. Rear cross-path warning costs extra on the Corolla.

Both the K5 and the Corolla have standard driver and passenger frontal airbags, front and rear side-impact airbags, driver knee airbags, side-impact head airbags, front seatbelt pretensioners, front wheel drive, height adjustable front shoulder belts, plastic fuel tanks, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, crash mitigating brakes, daytime running lights, lane departure warning systems, rearview cameras and driver alert monitors.

The National Highway Traffic Safety Administration does 35 MPH front crash tests on new vehicles. In this test, results indicate that the Kia K5 is safer than the Toyota Corolla:

	K5	Corolla
	Driver
STARS	5 Stars	5 Stars
Neck Injury Risk	21%	27%
Neck Stress	180 lbs.	243 lbs.
Neck Compression	21 lbs.	50 lbs.

The National Highway Traffic Safety Administration does side impact tests on new vehicles. In this test, which crashes the vehicle into a flat barrier at 38.5 MPH and into a post at 20 MPH, results indicate that the Kia K5 is safer than the Toyota Corolla:

	K5	Corolla
	Front Seat
STARS	5 Stars	5 Stars
Hip Force	264 lbs.	330 lbs.
	Into Pole
STARS	5 Stars	5 Stars
Spine Acceleration	32 G’s	32 G’s
Hip Force	589 lbs.	623 lbs.

New test not comparable to pre-2011 test results. More stars = Better. Lower test results = Better.

For its top level performance in IIHS driver and passenger-side small overlap frontal, moderate overlap frontal, side impact, roof strength and head restraint tests, its standard front crash prevention system, and its headlight’s “Good” rating, the Insurance Institute for Highway Safety grants the K5 its highest rating: “Top Safety Pick Plus” for 2019, a rating granted to only 126 vehicles tested by the IIHS. The Corolla is only a standard “Top Safety Pick” for 2019.

Warranty

The K5 comes with a full 5-year/60,000-mile basic warranty, which covers the entire car and includes 24-hour roadside assistance. The Corolla’s 3-year/36,000-mile basic warranty expires 2 years or 24,000 miles sooner.

Kia’s powertrain warranty covers the K5 5 years and 40,000 miles longer than Toyota covers the Corolla. Any repair needed on the engine, transmission, axles, joints or driveshafts is fully covered for 10 years or 100,000 miles. Coverage on the Corolla ends after only 5 years or 60,000 miles.

Reliability

To reliably start during all conditions and help handle large electrical loads, the K5 has a standard 760-amp battery. The Corolla’s standard 295-amp battery and largest (SE/XSE) 360 amp battery aren’t as powerful.

J.D. Power and Associates’ 2022 Initial Quality Study of new car owners surveyed provide the statistics that show that Kia vehicles are better in initial quality than Toyota vehicles. J.D. Power ranks Kia fourth in initial quality, above the industry average. With 16 more problems per 100 vehicles, Toyota is ranked 14th.

J.D. Power and Associates’ 2022 survey of the owners of three-year-old vehicles provides the statistics that show that Kia vehicles are more reliable than Toyota vehicles. J.D. Power ranks Kia first in reliability, above the industry average. With 13 more problems per 100 vehicles, Toyota is ranked fifth.

Engine

The K5 1.6T’s standard 1.6 turbo 4-cylinder produces 11 more horsepower (180 vs. 169) and 44 lbs.-ft. more torque (195 vs. 151) than the Corolla’s 2.0 DOHC 4-cylinder. The K5 GT 2.5T’s standard 2.5 turbo 4-cylinder produces 121 more horsepower (290 vs. 169) and 160 lbs.-ft. more torque (311 vs. 151) than the Corolla’s 2.0 DOHC 4-cylinder.

As tested in Car and Driver the Kia K5 is faster than the Toyota Corolla:

	K5 1.6T	K5 GT 2.5T	Corolla
Zero to 60 MPH	7 sec	5.1 sec	8.2 sec
Zero to 100 MPH	18.8 sec	12 sec	22.8 sec
5 to 60 MPH Rolling Start	7.4 sec	5.5 sec	8.8 sec
Quarter Mile	15.5 sec	13.7 sec	16.4 sec
Speed in 1/4 Mile	92 MPH	106 MPH	87 MPH
Top Speed	128 MPH	12 MPH	118 MPH

Fuel Economy and Range

In heavy traffic or at stoplights the K5 LX’s engine automatically turns off when the vehicle is stopped, saving fuel and reducing pollution. The engine is automatically restarted when the driver gets ready to move again. The Corolla doesn’t offer an automatic engine start/stop system.

To lower fuel costs and make buying fuel easier, the Kia K5 uses regular unleaded gasoline. The Corolla requires premium for maximum efficiency, which can cost 20 to 55 cents more per gallon.

The K5 has 2.6 gallons more fuel capacity than the Corolla (15.8 vs. 13.2 gallons), for longer range between fill-ups.

Brakes and Stopping

For better stopping power the K5’s brake rotors are larger than those on the Corolla:

	K5	K5 GT	Corolla
Front Rotors	12 inches	13.6 inches	10.8 inches
Rear Rotors	11.2 inches	12.8 inches	10.2 inches

The K5 stops much shorter than the Corolla:

	K5	Corolla
70 to 0 MPH	172 feet	179 feet	Car and Driver
60 to 0 MPH	116 feet	128 feet	Motor Trend
60 to 0 MPH (Wet)	140 feet	143 feet	Consumer Reports

Tires and Wheels

For better traction, the K5 GT’s tires are larger than the largest tires available on the Corolla (245/40R19 vs. 225/40R18).

For better ride, handling and brake cooling the K5 GT has standard 19-inch wheels. The Corolla’s largest wheels are only 18-inches.

Suspension and Handling

The K5 has vehicle speed sensitive variable-assist power steering, for low-effort parking, better control at highway speeds and during hard cornering, and a better feel of the road. The Corolla doesn’t offer variable-assist power steering.

For a smoother ride and more stable handling, the K5’s wheelbase is 5.9 inches longer than on the Corolla (112.2 inches vs. 106.3 inches).

For better handling and stability, the average track (width between the wheels) on the K5 is 3.5 inches wider in the front and 3.1 inches wider in the rear than the track on the Corolla.

The K5 GT-Line AWD handles at .86 G’s, while the Corolla XSE pulls only .81 G’s of cornering force in a Motor Trend skidpad test.

The K5 GT executes Motor Trend’s “Figure Eight” maneuver 1.8 seconds quicker than the Corolla XSE (26.3 seconds @ .69 average G’s vs. 28.1 seconds @ .58 average G’s).

Chassis

The design of the Kia K5 amounts to more than styling. The K5 has an aerodynamic coefficient of drag of .27 Cd. That is significantly lower than the Corolla (.31) and many sports cars. A more efficient exterior helps keep the interior quieter and helps the K5 get better fuel mileage.

As tested by Car and Driver, the interior of the K5 EX is quieter than the Corolla:

	K5	Corolla
70 MPH Cruising	67 dB	71 dB

Passenger Space

Because it has more passenger and cargo room, the EPA rates the K5 a Large car, while the Corolla is rated a Compact.

The K5 has 16.7 cubic feet more passenger volume than the Corolla (105.3 vs. 88.6).

The K5 has 1.9 inches more front headroom, 4.1 inches more front legroom, 2.7 inches more front hip room, 4 inches more front shoulder room, .7 inches more rear headroom, .4 inches more rear legroom, 5.3 inches more rear hip room and 4.4 inches more rear shoulder room than the Corolla.

Cargo Capacity

The K5 has a much larger trunk than the Corolla (16 vs. 13.2 cubic feet).

To make loading groceries and cargo easier when your hands are full, the K5’s trunk can be opened just by waiting momentarily behind the back bumper, leaving your hands completely free. The Corolla doesn’t offer a hands-free gesture to open its trunk, forcing you to put cargo down if your hands are full.

Servicing Ease

The K5 uses gas struts to support the hood for easier service access. The Corolla uses a prop rod to support its heavy hood. It takes two hands to open the hood and set the prop rod, the prop rod gets in the way during maintenance and service, and the prop rod could be knocked out, causing the heavy hood to fall on the person maintaining or servicing the car.

Ergonomics

When two different drivers share the K5 EX/GT, the optional memory seats and mirrors make it convenient for both. Each setting activates different, customized memories for the driver’s seat position and outside mirror angle. The Corolla doesn’t offer a memory system.

The K5 EX/GT’s optional easy entry system glides the driver’s seat back when the door is unlocked or the ignition is switched off, making it easier for the driver to get in and out. The Corolla doesn’t offer an easy entry system.

The K5’s power window, power lock, power mirror and cruise control switches are lit from behind, making them plainly visible and easier to operate at night. The Corolla’s power window (except driver window) and power lock switches are unlit, making them difficult to find at night and operate safely.

Consumer Reports rated the K5’s headlight performance “Good,” a higher rating than the Corolla’s headlights, which were rated “Fair.”

The Insurance Institute for Highway Safety (IIHS) conducts detailed tests on headlights for their range both straight ahead and in curves and to be certain they don’t exceed acceptable amounts of glare to oncoming drivers. The K5’s headlights were rated “Good” by the IIHS, while the Corolla’s headlights are rated “Acceptable.”

The K5’s standard outside mirrors include heating elements to clear off the mirrors for better visibility. Toyota charges extra for heated mirrors on the Corolla.

The K5’s optional rear view mirror has an automatic dimming feature. This mirror can be set to automatically darken quickly when headlights shine on it, keeping following vehicles from blinding or distracting the driver. The Corolla doesn’t offer the luxury of an automatic dimming rear view mirror.

Optional air-conditioned seats in the K5 (except LXS/GT-Line) keep the driver and front passenger comfortable and take the sting out of hot seats in Summer. The Corolla doesn’t offer air-conditioned seats.

On extremely cold winter days, the K5’s optional (except LXS) heated steering wheel provides comfort, allowing the driver to steer safely and comfortably before the car heater warms up. The Corolla doesn’t offer a heated steering wheel.

The K5’s 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. The Corolla doesn’t offer dual zone air conditioning.

Both the K5 and the Corolla offer rear vents. For greater rear passenger comfort, the K5 EX/GT has standard rear air conditioning vents to keep rear occupants cool in summer or warm in winter. The Corolla doesn’t offer rear air conditioning vents, only heat vents.

Recommendations

J.D. Power and Associates rated the K5 first among midsize cars in owner reported satisfaction. This includes how well the vehicle performs and satisfies its owner’s expectations. The Corolla isn’t in the top three in its category.
