Compare the2025 Kia Sorento HybridVS 2025 Rivian R1S

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 Sorento Hybrid are reminded to check the back seat when a sensor determines the back seat is occupied. The R1S doesn’t offer a back seat reminder.

With its standard Forward Collision-Avoidance Assist, the Kia Sorento Hybrid is better at preventing collisions with pedestrians than the Rivian R1S, according to the Insurance Institute for Highway Safety:

In a Vehicle-to-Vehicle Frontal Crash Prevention 2.0 test conducted by the Insurance Institute for Highway Safety (IIHS), the Kia Sorento Hybrid achieved a “Good” rating - the highest possible - for its performance in forward collision warning and automatic braking systems, demonstrating its excellent capabilities in preventing collisions. The Rivian R1S has not been tested.

Over 200 people are killed each year when backed over by motor vehicles. The Sorento Hybrid SX Prestige has standard Parking Collision Avoidance-Rear that uses rear sensors to monitor for objects to the rear and automatically applies the brakes to prevent a collision. The R1S doesn’t offer backup collision prevention brakes.

When descending a steep, off-road slope, the Sorento Hybrid’s standard Downhill Brake Control allows you to creep down safely. The R1S doesn’t offer Downhill Brake Control.

Both the Sorento Hybrid and R1S have rear cross-traffic warning, but the Sorento Hybrid has Rear Cross-Traffic Collision-Avoidance Assist (automatically applies the brakes) to better prevent a collision when backing near traffic. The R1S’ Rear Cross-Traffic Warning doesn’t automatically brake.

Both the Sorento Hybrid and the R1S have standard driver and passenger frontal airbags, front side-impact airbags, driver 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, crash mitigating brakes, daytime running lights, lane departure warning systems, blind spot warning systems, rearview cameras, rear cross-path warning, driver alert monitors, available all wheel drive and around view monitors.

The Sorento Hybrid comes with a full 5-year/60,000-mile basic warranty, which covers the entire truck and includes 24-hour roadside assistance. The R1S’ 4-year/50,000-mile basic warranty expires 1 year or 10,000 miles sooner.

Kia’s powertrain warranty covers the Sorento Hybrid 2 years longer than Rivian covers the R1S. Any repair needed on the engine, transmission, axles, joints or driveshafts is fully covered for 10 years or 100,000 miles. Coverage on the R1S ends after only 8 years.

There are over 16 times as many Kia dealers as there are Rivian dealers, which makes it much easier should you ever need service under the Sorento Hybrid’s warranty.

From surveys of all its subscribers, Consumer Reports’ March 2025 Auto Issue reports that Kia vehicles are more reliable than Rivian vehicles. Consumer Reports ranks Kia 13 places higher in reliability than Rivian.

The Sorento Hybrid stops shorter than the R1S:

The Sorento Hybrid’s tires provide better handling because they have a lower 55 series profile (height to width ratio) that provides a stiffer sidewall than the R1S’ 65 series tires.

The Sorento Hybrid EX handles at .80 G’s, while the R1S Ascend Tri Max pulls only .77 G’s of cornering force in a Motor Trend skidpad test.

For better maneuverability, the Sorento Hybrid’s turning circle is 3.4 feet tighter than the R1S Quad Max Ascend’s (37.9 feet vs. 41.3 feet). The Sorento Hybrid’s turning circle is 5.4 feet tighter than the R1S’ (37.9 feet vs. 43.3 feet).

The Kia Sorento Hybrid may be more efficient, handle and accelerate better because it weighs about 2250 to 2450 pounds less than the Rivian R1S.

The Sorento Hybrid is 11.2 inches shorter than the R1S, making the Sorento Hybrid easier to handle, maneuver and park in tight spaces.

The Sorento Hybrid is 7.2 inches narrower than the R1S, making the Sorento Hybrid easier to handle and maneuver in traffic.

The Sorento Hybrid is 10.6 inches shorter in height than the R1S, making the Sorento Hybrid much easier to wash and garage and drive (lower center of gravity).

For excellent aerodynamics, the Sorento Hybrid has standard flush composite headlights. The R1S has recessed headlights that spoil its aerodynamic shape and create extra drag.

The Sorento Hybrid has .7 inches more front hip room, 4.1 inches more rear legroom, .9 inches more rear hip room and 1.9 inches more third row shoulder room than the R1S.

The Sorento Hybrid has a standard third row seat which folds flat into the floor. This completely clears a very large cargo area quickly. The R1S doesn’t offer seats that fold into the floor.

A standard locking glovebox (which can’t be accessed with the valet key) keeps your small valuables safer in the Sorento Hybrid. The R1S doesn’t offer locking storage for small valuables.

The Sorento Hybrid’s liftgate lifts up in one piece, completely out of the way of loading and unloading, while sheltering the cargo loading area. The R1S’ tailgate’s top part raises up, but the bottom part lowers, getting in the way of loading and making an uneven surface for sliding cargo.

To make loading groceries and cargo easier when your hands are full, the Sorento Hybrid’s liftgate can be opened just by waiting momentarily behind the back bumper, leaving your hands completely free. The R1S doesn’t offer a hands-free gesture to open its tailgate, forcing you to put cargo down if your hands are full.

The Sorento Hybrid’s standard side window demisters help clear frost or condensation from the side windows in the winter. The R1S doesn’t even offer side window demisters, so the driver may have to wipe the windows from the outside to gain side vision.

Manual rear side window sunshades are available in the Sorento Hybrid to help block heat and glare for the rear passengers. The R1S doesn’t offer rear side window sunshades.

When the Sorento Hybrid SX Prestige 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 R1S’ mirrors don’t automatically adjust for backing.

Compared to the Rivian R1S’ traditional radio, the Kia Sorento Hybrid equipped with standard SiriusXM satellite radio provides an unmatched listening experience. Its extensive coverage guarantees consistent, crystal-clear reception across the continental U.S., and access to over 100 channels dedicated to a multitude of genres, including music, news, sports, talk shows, and comedy, many with only limited commercial breaks.

The Sorento Hybrid is available in both front-wheel drive and four-wheel drive configurations. The R1S doesn’t offer a two-wheel drive configuration.

Consumer Reports® recommends the Kia Sorento Hybrid, based on reliability, safety and performance. The Rivian R1S isn't recommended.

The Kia Sorento outsold the Rivian R1S by almost four to one during 2024.
