Compare the2024 Hyundai ElantraVS 2023 Kia Rio

Over 200 people are killed each year when backed over by motor vehicles. The Elantra Limited has standard Reverse Parking Collision Avoidance Assist that uses rear sensors to monitor for objects to the rear and automatically applies the brakes to prevent a collision. The Rio doesn’t offer backup collision prevention brakes.

The Elantra’s standard lane departure warning system alerts a temporarily inattentive driver when the vehicle begins to leave its lane and gently nudges the vehicle back towards its lane. A lane departure warning system costs extra on the Rio and is only available on Rio S.

The Elantra’s blind spot warning system 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. The Rio doesn’t offer a system to reveal objects in the driver’s blind spots.

To help make backing out of a parking space safer, the Elantra’s standard Rear Cross-Traffic Collision Warning uses sensors in the rear to alert the driver to vehicles approaching from the side and Rear Cross-Traffic Collision-Avoidance Assist automatically engages the brakes to help avoid a collision. The Rio doesn’t offer a rear cross-path warning system.

Both the Elantra and the Rio have standard driver and passenger frontal airbags, front side-impact 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, daytime running lights, rearview cameras and available rear parking sensors.

The Hyundai Elantra achieved a “Top Safety Pick” rating from the Insurance Institute for Highway Safety (IIHS) for the 2024 model year. This recognition was based on its impressive performance in the small overlap frontal crash test, updated side impact crash test, headlight evaluations, and pedestrian crash prevention testing. The Rio is not a “Top Safety Pick” for 2024.

The Elantra’s corrosion warranty is 2 years and unlimited miles longer than the Rio’s (7/unlimited vs. 5/100,000).

Hyundai pays for scheduled maintenance on the Elantra for 3 years and 36,000 miles. Hyundai will pay for oil changes, tire rotations, air filter replacements, cabin filter replacement, brake fluid replacement, inspections, and any other required maintenance. Kia doesn’t pay scheduled maintenance for the Rio.

To reliably power the ignition and other systems and to recharge the battery, the Elantra has a standard 150-amp alternator. The Rio’s 130-amp alternator isn’t as powerful.

To reliably start during all conditions and help handle large electrical loads, the Elantra has a standard 760-amp battery. The Rio’s 640-amp battery isn’t as powerful.

A reliable vehicle saves its owner time, money and trouble. Nobody wants to be stranded or have to be without a vehicle while it’s being repaired. Consumer Reports rates the Elantra’s reliability 11 points higher than the Rio.

The Elantra’s 2.0 DOHC 4-cylinder produces 27 more horsepower (147 vs. 120) and 20 lbs.-ft. more torque (132 vs. 112) than the Rio’s 1.6 DOHC 4-cylinder.

In heavy traffic or at stoplights the Elantra SE’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. If the conditions warrant or the driver wishes, the system can be manually disabled at any time for the duration of a trip. The Rio doesn’t offer an automatic engine start/stop system.

In its Green Vehicle Guide, the U.S. Environmental Protection Agency (EPA) rates the Hyundai Elantra higher (7 out of 10) than the Kia Rio (3). This means the Elantra produces up to 24.5 pounds less smog-producing pollutants than the Rio every 15,000 miles.

The Hyundai Elantra has standard four-wheel disc brakes for better stopping power and improved directional control in poor weather. Rear drums are standard on the Rio. Drums can heat up and make stops longer, especially with antilock brakes that work much harder than conventional brakes.

The Elantra stops shorter than the Rio:

	Elantra	Rio

60 to 0 MPH (Wet)	139 feet	140 feet	Consumer Reports

For better traction, the Elantra has larger standard tires than the Rio (195/65R15 vs. 185/65R15). The Elantra’s optional tires are larger than the largest tires available on the Rio (225/45R17 vs. 185/65R15).

The Elantra’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 Rio’s 65 series tires.

For better ride, handling and brake cooling the Elantra offers optional 17-inch wheels. The Rio’s largest wheels are only 15-inches.

The Hyundai Elantra’s wheels have 5 lugs for longer wheel bearing life, less chance of rotor warping and greater strength. The Kia Rio only has 4 wheel lugs per wheel.

The Elantra 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 Rio doesn’t offer variable-assist power steering.

For a smoother ride and more stable handling, the Elantra’s wheelbase is 5.5 inches longer than on the Rio (107.1 inches vs. 101.6 inches).

For better handling and stability, the average track (width between the wheels) on the Elantra is 2.4 inches wider in the front and 2.6 inches wider in the rear than the track on the Rio.

Because it has more passenger and cargo room, the EPA rates the Elantra a Mid-size car, while the Rio Sedan is rated a Compact.

The Elantra has 9.5 cubic feet more passenger volume than the Rio Sedan (99.4 vs. 89.9).

The Elantra has 1.7 inches more front headroom, .2 inches more front legroom, .5 inches more front hip room, 2.4 inches more front shoulder room, 4.5 inches more rear legroom and 2.3 inches more rear shoulder room than the Rio Sedan.

The Elantra has a larger trunk than the Rio Sedan (14.2 vs. 13.7 cubic feet).

The Elantra’s available rear seats fold to accommodate long and bulky cargo. The Rio LX doesn’t offer folding rear seats.

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

To help each driver find a more comfortable driving position, the Elantra has a telescoping steering wheel. Much better than just a tilt steering wheel or adjustable seat, this allows a short driver to sit further from the steering wheel while maintaining contact with the pedals. The Rio doesn’t offer a telescoping steering wheel.

The Elantra SEL/Limited’s driver’s power window opens or closes with one touch of the window control. The Rio’s driver’s power window switch has to be held the entire time to close it fully.

The Elantra’s LED headlights produce a whiter, brighter light (up to 3x) using five times less power than the Rio’s standard halogen headlights. LED lights also light instantly and last over twenty times longer than halogen.

The Elantra (except SE) offers optional heated front seats, which keep the driver and front passenger extremely comfortable in the winter. Heated seats aren’t available in the Rio.

The Elantra offers an optional center folding armrest for the rear passengers. A center armrest helps make rear passengers more comfortable and it can provide a boundary between children. The Rio doesn’t offer a rear seat center armrest.

The Elantra SEL/Limited’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 Rio doesn’t offer dual zone air conditioning.

To keep a safe, consistent following distance, the Elantra (except SE) offers an optional Smart Cruise Control, which alters the speed of the vehicle without driver intervention. This allows the driver to use cruise control more safely without constantly having to disengage it when approaching slower traffic. The Rio doesn’t offer an adaptive cruise control.

The Elantra SEL/Limited’s standard GPS navigation system has a real-time traffic update feature that plots alternative routes to automatically bypass traffic problems. (Service not available in all areas.) The Rio’s available navigation system doesn’t offer real-time traffic updates.

With standard voice command, the Elantra Limited offers the driver hands free control of the radio, climate controls and the navigation computer by simply speaking. The Rio doesn’t offer a voice control system.

To quickly and conveniently keep personal devices charged without cables tangling and wearing out, the Hyundai Elantra (except SE) offers an optional wireless phone charging system (Qi) in the center console. The Rio doesn’t offer wireless personal charging.
