The RDX Advance has a standard Surround-View Camera System to allow the driver to see objects all around the vehicle on a screen. The Seltos only offers a rear monitor.

Both the RDX and the Seltos 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, four-wheel antilock brakes, traction control, electronic stability systems to prevent skidding, rearview cameras, available all-wheel drive, blind spot warning systems and rear cross-path warning.

The Acura RDX weighs 466 to 1120 pounds more than the Kia Seltos. The NHTSA advises that heavier vehicles are much safer in collisions than their significantly lighter counterparts.

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 vehicle-to-vehicle front crash prevention system, its standard vehicle-to-pedestrian front crash prevention system, and its standard headlight’s “Good” rating, the Insurance Institute for Highway Safety grants the RDX its highest rating: “Top Pick Plus” for 2020, a rating granted to only 30 vehicles tested by the IIHS. The Seltos has not been tested, yet.

The RDX has 3.9 gallons more fuel capacity than the Seltos (17.1 vs. 13.2 gallons), for longer range between fill-ups.

The RDX has a standard cap-less fueling system. The fuel filler is automatically opened when the fuel nozzle is inserted and automatically closed when it’s removed. This eliminates the need to unscrew and replace the cap and it reduces fuel evaporation, which causes pollution. The Seltos doesn’t offer a cap-less fueling system.

For better traction, the RDX has larger standard tires than the Seltos (235/55R19 vs. 215/55R17). The RDX A-Spec’s tires are larger than the largest tires available on the Seltos (255/40R20 vs. 235/45R18).

The RDX A-Spec’s tires provide better handling because they have a lower 40 series profile (height to width ratio) that provides a stiffer sidewall than the Seltos Turbo’s 45 series tires.

For better ride, handling and brake cooling the RDX has standard 19-inch wheels. Smaller 17-inch wheels are standard on the Seltos 2.0L. The RDX A-Spec’s 20-inch wheels are larger than the 18-inch wheels on the Seltos Turbo.

The RDX has a standard easy tire fill system. When inflating the tires, the vehicle’s integrated tire pressure sensors keep track of the pressure as the tires fill and tell the driver when the tires are inflated to the proper pressure. The Seltos doesn’t offer vehicle monitored tire inflation.

For superior ride and handling, the Acura RDX has fully independent front and rear suspensions. An independent suspension allows the wheels to follow the road at the best angle for gripping the pavement, without compromising ride comfort. The Seltos 4x2 has a rear torsion beam axle, with a semi-independent rear suspension.

The RDX offers an optional 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 or off-road. The Seltos’ suspension doesn’t offer adjustable shock absorbers.

The RDX 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 Seltos doesn’t offer variable-assist power steering.

For a smoother ride and more stable handling, the RDX’s wheelbase is 4.8 inches longer than on the Seltos (108.3 inches vs. 103.5 inches).

For better handling and stability, the track (width between the wheels) on the RDX is 2.2 inches wider in the front and 2.3 inches wider in the rear than on the Seltos.

For greater off-road capability the RDX has a greater minimum ground clearance than the Seltos (8.2 vs. 7.3 inches), allowing the RDX to travel over rougher terrain without being stopped or damaged.

The RDX has a much larger cargo volume with its rear seat up than the Seltos with its rear seat up (31.1 vs. 26.6 cubic feet). The RDX has a much larger cargo volume with its rear seat folded than the Seltos with its rear seat folded (79.8 vs. 62.8 cubic feet).

Pressing a switch automatically lowers the RDX’s rear seats, to make changing between passengers and cargo easier. The Seltos doesn’t offer automatic folding seats.

To make loading and unloading groceries and cargo easier, especially for short adults, the RDX has a standard power liftgate, which opens and closes automatically by pressing a button, or on the RDX Advance, by just kicking your foot under the back bumper, completely leaving your hands free. The Seltos doesn’t offer a power liftgate.

When two different drivers share the RDX, the memory system makes it convenient for both. Each keyless remote activates different, customized memories for the driver’s seat position, outside mirror angle, climate settings and radio stations. The Seltos doesn’t offer a memory system.

The RDX’s standard easy entry system glides the driver’s seat back, making it easier for the driver to get in and out. The Seltos doesn’t offer an easy entry system.

The RDX Advance has a standard heads-up display that projects speed and navigation instruction readouts in front of the driver’s line of sight, allowing drivers to view information without diverting their eyes from the road. The Seltos doesn’t offer a heads-up display.

The RDX’s power parking brake sets with one touch and releases with one touch or automatically. The Seltos has a lever-type parking brake that has to be strenuously raised to engage properly. It has to be lifted up more and a button depressed to release it.

The RDX’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 Seltos’ power window switches have to be held the entire time to close them fully. Only its driver’s window opens automatically.

If the windows are left open on the RDX 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 Seltos can only operate the windows from inside the vehicle, with the ignition on.

The RDX’s standard speed-sensitive wipers speed up when the vehicle does, so that the driver doesn’t have to continually adjust the speed of the wipers. The Seltos’ manually variable intermittent wipers have to be constantly adjusted. The RDX Advance’s standard wipers adjust their speed and turn on and off automatically according to the amount of rainfall on the windshield.

The RDX’s standard outside mirrors include heating elements to clear off the mirrors for better visibility. Kia only offers heated mirrors on the Seltos S/EX/SX.

When the RDX 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 Seltos’ mirrors don’t automatically adjust for backing.

The RDX’s standard rear and side view mirrors have an automatic dimming feature. These mirrors can be set to automatically darken quickly when headlights shine on them, keeping following vehicles from blinding or distracting the driver. The Seltos offers an automatic rear view mirror, but its side mirrors don’t dim.

The RDX has standard heated front seats. Heated front seats cost extra on the Seltos, and aren’t available on the Seltos LX. The RDX Advance also has standard heated rear seats to keep those passengers extremely comfortable in the winter. Heated rear seats aren’t available in the Seltos.

Optional air-conditioned seats in the RDX keep the driver and front passenger comfortable and take the sting out of hot seats in Summer. The Seltos doesn’t offer air-conditioned seats.

On extremely cold winter days, the RDX’s optional heated steering wheel provides comfort, allowing the driver to steer safely and comfortably before the vehicle heater warms up. The Seltos doesn’t offer a heated steering wheel.

The RDX’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 Seltos doesn’t offer dual zone air conditioning.
