Kia Sorento vs Rivian R1T

What's the difference?

The Kia Sorento GT-Line PHEV is a sumptuously equipped seven-seater that delivers comfort, tech and an easy-going drive. It presents well on the surface, and for the right buyer (one who can make the most of its plug-in capabilities ) it could be a smart, low-emissions option for family life.

But for all its polish, it doesn’t quite do enough to justify itself as the best Sorento in the range. The electric-only driving range isn’t especially generous, and the higher price tag , combined with its lower towing capacity, may leave some families wondering whether the diesel variant is the more practical choice.

It’s not a bad car by any means, but the flagship GT-Line PHEV feels more like a stepping stone than a standout.

Having finally experienced the Rivian R1T from the driver's seat I think this is a ute that would have plenty of appeal in the Australian market. Not as a competitor to a Toyota HiLux Workmate or similar working-class ute, but as an alternative to the likes of the HiLux Rogue, Ford Ranger Raptor or even the new Ranger Platinum.

This is a high-end, luxury ute that also happens to be electric, which only expands its appeal. It has seriously impressive performance and, while we didn't get to test them first-hand, strong off-road credentials. Add to that a premium look and feel to the cabin and loads of practicality and it's easy to see this finding an audience here.

The biggest question will be cost, because even at a direct price conversion (which isn't a clear reflection of shipping and local tariffs) the R1T will start well over $100,000. Even by today's standards of six-figure US utes like the Chevrolet Silverado 1500 and incoming Ford F-150, that will be a hard sell and could restrict its chances.

Which would be a shame because while Tesla has a clear head start in Australia, it's possible for Rivian to follow in its wheel tracks and have plenty of mainstream success.

Note: CarsGuide attended this event as a guest of the manufacturer, with travel, accommodation and meals provided.

The Sorento looks exactly how a modern SUV should - confident, capable, and well-proportioned without feeling bulky. It wears its size well, delivering that commanding presence families often want in a seven-seater, without coming across as too aggressive.

I especially like the 19-inch alloy wheels as they suit the vehicle’s stance perfectly. I also like the striking LED lighting signatures front and rear, which really come to life after dark.

Step inside and the cabin strikes a neat balance between tech-forward and user-friendly. You’re greeted by dual 12.3-inch widescreen displays that make a strong first impression, but thankfully Kia hasn’t gone all-digital! You still get physical buttons and dials where they matter, making everything feel intuitive and easy to navigate.

Material quality is a highlight. There’s quilted Nappa leather upholstery, soft-touch surfaces throughout, and even a luxe suede headliner. These premium touches, coupled with the panoramic sunroof, lift the ambience and it's a cabin that feels genuinely upmarket, but not at the cost of family friendly functionality.

There's a lot to say about the design of the R1T. Unlike Tesla, which has gone radical in the design of its Cybertruck, Rivian clearly made a decision not to be too polarising but also leverage the advantages of electrification. The result is a ute that stands out even amid the glut of pick-ups on American roads.

Rivian also opted not to compete directly with the massively popular Ford F-150, Ram 1500 and Chevrolet Silverado in the US, instead sizing the R1T in what's considered the 'compact pick-up' market in the US. That makes it pretty much on par with the likes of the Ford Ranger and Toyota HiLux that we flock to in Australia. The R1T measures 5514mm long, 2077mm wide and 1986mm tall, which compares to 5446mm, 1852mm and 1977mm for the Ranger dual-cab.

Inside, like so many modern cars (and not just EVs), Rivian has opted for a minimalist design aesthetic, running almost every function through the central multimedia touchscreen, with only two physical buttons in the entire cabin, a pair of dials/buttons on the steering wheel and a pair of stalks behind the wheel (left for the indicators and right for the gear selector).

There isn't even a button to alter the power adjustable steering column, instead steering wheel position and mirrors are controlled via the touchscreen and the dials on the wheel. You have to select what function you want and that activates the wheel switches, allowing you to adjust for both reach and height.

It's arguably an unnecessarily complex system for something that should be simple, but for owners that can most likely do it once and then save their preferred position it's ultimately not a big deal; still, would one small button set on the steering column have been that complicated?

As you should expect for the price, the R1T quad-motor has a premium look and feel to its interior. The synthetic leather and dark ash wood make for a luxury car feeling, feeding to that simplistic but very hi-tech and polished design aesthetic.

Space up front is generous, with excellent seat comfort thanks to wide seat bases, extendable under-thigh support and heating and ventilation. Getting in and out is easy, too, helped by wide door openings and a manageable 176mm ground clearance.

Storage throughout the cabin is thoughtful and abundant. Up front, there’s a large glovebox, a spacious centre console with a removable shelf, two cupholders, door bins with bottle holders, and a handy phone cubby beneath the dash.

The second row adds its own bottle holders and storage bins in each door, map pockets, four cupholders (including one cleverly placed on each door) and a removable floor shelf in front of the centre seat.

Even the third row isn’t forgotten, with a snack cubby and cupholder built into each wheel arch.

Tech-wise, the dual 12.3-inch displays look sharp, and the media system is intuitive and quick to respond. The instrument cluster isn’t particularly customisable, and I’m not a huge fan of the layout, but it displays the essentials clearly. You also get a head-up display, satellite navigation with over-the-air updates, and both wireless and wired Apple CarPlay and Android Auto.

Charging options are solid across all three rows, with multiple USB-C ports, a 12-volt socket in the second row and boot, and a wireless charging pad up front.

The second row offers ample legroom, though headroom is slightly reduced due to the panoramic sunroof. The lack of a transmission tunnel is a win for middle seat comfort, and the bench is wide enough to accommodate three child seats side-by-side. There are three top-tether points and ISOFIX anchors on the outboard seats.

Comfort and convenience features in the second row include heated outboard seats, device pockets, directional air vents, and the same handy storage and charging options mentioned earlier. My son especially loves the retractable sunblinds and the cupholders built into the door handles as they’re easy to reach and super practical. I am, however, disappointed that there’s no separate climate control zone for this row.

As for the third row, it’s best treated as a sometimes seat for adults. Access is more child-sized, and amenities are limited, but you do get directional air vents and a fan control, which are definitely appreciated.

Boot space is tight with all three rows in use, at just 175L, but that was still enough for the odd errand during the week. Fold the third row down and you get a much more usable 604L. Both rows fold completely flat, making it easy to slide in larger items, and the GT-Line includes a powered tailgate and a rare full-size spare wheel for extra convenience.

This is one of the areas that Rivian has excelled at and it makes the R1T a real standout in its class. Because it's a bespoke design there are a number of clever practical features around the cabin.

Starting with the Bluetooth speaker that slides out of the centre console. So you can play your music through the car's speakers or, when you leave the car, take your tunes with you. The sound system is another in-house Rivian set-up, like the multimedia, with the company splitting with original partner, audio specialist, Meridian.

Other clever interior touches include the charging pad (complete with tiny Rivian logo pattern), a sizable centre console box and a torch recessed in the door. There are also a power outlets in the cabin, rather than just USB ports, so you can charge your electronics on the move.

Rivian has also developed a 'Pet Mode' for the cabin, which the company claims allows owners to safely leave their pets in the car. The system allows the air-conditioning to keep running, even while the ignition is off, so your pet doesn't get overheated or freeze, and the media screen displays a message saying that your pet is okay (so no good Samaritan smashes your window to save your animal friend).

The R1T's other major party trick is the 'cargo tunnel' that runs the width of the car, taking advantage of the empty space between the cabin and the tray. This is a unique feature for the R1T, allowing for an extra 331 litres of lockable storage, which can be accessed on both sides or through the cabin via the rear seats.

Rivian even showed off a 'Camp Kitchen' that could slide in and out of the tunnel. This elaborate accessory was designed to make camping easier, featuring an induction cooktop, sink and crockery, but it has since been removed from the company's website as it is reportedly redesigned. Hopefully it's available again by the time the R1T makes it to Australia.

This would work in tandem with the 'Camp Mode' function that lets the ute self-level its suspension so the body is flat on uneven ground and turns off the exterior lights and sounds not to distract others, while still allowing you to use the power outlets in the tray and cargo tunnel.

As for the space in the cabin, it's good in the front and rear. With a 3449mm wheelbase there's generous room for the rear occupants that allows for two adults to sit in comfort, and Rivian claims it's wide enough for three child seats.

As for storage, in addition to the cargo tunnel, there's under bonnet storage measuring 314 litres, so there's plenty of out-of-sight space despite it being a ute.

The tray measures quite square, at 1374mm long and 1297mm wide, but Rivian has designed the tailgate to sit flush with the tray bed, which can extend the usable length to 2131mm.

The tray itself has several handy features. These include multiple power outlets and an air-compressor, so you can add extra pressure to your tyres if you let them down to go off-roading or pump up camping equipment.

Underneath the tray is the housing to keep the spare tyre on the off-road package, but as a spare isn't available on all models as standard, it can be used as storage for wet or dirty items because it's washable and has a drainage hole.

As many of these new car companies have found, including Tesla with its long-gestation periods for the Model 3, Model Y and now Cybertruck, mass-producing motor vehicles isn't an easy task. So, to simplify things and help get its business up and running, Rivian has focused on a single R1T variant for the US market initially.

This is the range-topping quad-motor R1T, with four electric motors (two per axle), which is priced from US$89,000 (approx. A$139,000)

That should give you an idea of where Rivian has positioned the R1T in the US market. This isn't a 'working-class ute'. This is one of the new breed of lifestyle vehicles that have become increasingly popular in the US and Australia.

Rivian has plans for a more affordable dual-motor (one per axle) model, which will start at US$73,000 (approx. A$114,000), and be able to be upgraded with a 'Performance' motor package for US$5000 or the choice of a 'Large' battery for US$6000 (approx. A$9000) or the 'Max' battery for US$16,000 (approx. A$25,000). We'll explain the technical difference between those motors and batteries below.

As for standard equipment, the R1T comes with a 21-inch alloy wheel and 'road' tyre, a built-in air-compressor, 'Gear Guard' security cable (again, we'll explain in-depth later), synthetic leather trim, dark ash wood inlays, heated and ventilated seats and a heated steering wheel.

Notably absent is Apple CarPlay and Android Auto, with Rivian preferring its own bespoke Google-powered system.

There is an 'All-Terrain' package available, too, which swaps out 20-inch alloys with all-terrain tyres, underbody protection and a full-size spare, that's stored under the tray.

Rivian also offers a variety of accessories including MaxTrax recovery boards, first aid kits for humans and pets and an off-road recovery kit that includes straps, hitch link and gloves.

The company has also partnered with Yakima, an American company that specialises in adventure accessories, to offer a roof-mounted tent for the R1S (but doesn't currently offer it on the R1T configurator).

And if that's not enough accessories for you, Rivian sells a huge array of branded merchandise via its website, including shirts, hats, chargers, bike mounts, drink bottles and even pet gear.

Powering this GT-Line variant is a plug-in hybrid system that pairs a 1.6-litre turbocharged four-cylinder petrol engine with a small electric motor and battery. Combined, the system delivers up to 195kW of power and 350Nm of torque, which is plenty to get this sizeable SUV moving with confidence.

It’s a part-time all-wheel-drive set-up with a lock mode for extra traction when needed, and it’s paired with a smooth-shifting six-speed automatic transmission.

Around town and on the highway, the power delivery feels seamless and refined, with the electric motor doing a nice job of smoothing out stop-start driving.

One key trade-off, however, is towing capacity. While the diesel Sorento can tow up to 2000kg braked, the PHEV’s figure drops to just 1010kg. That’s a significant reduction and could be a deal-breaker for families who regularly tow a camper, trailer or boat.

There are three main powertrain options for the R1T - Dual-Motor AWD, Performance Dual-Motor AWD and Quad-Motor AWD.

Even as the entry-level model the Dual-Motor AWD makes 397kW/827Nm and can sprint from 0-60mph (96km/h) in just 4.5 seconds.

The Performance Dual-Motor AWD steps things up to 495kW/1123Nm and a sprint time of 3.5 seconds, while the Quad-Motor makes a very potent 622kW/1231Nm and takes just 3.0 seconds to run 0-60mph.

The Quad-Motor we tested comes standard with eight 'Drive Modes' that adjust the ride height, suspension stiffness, brake regeneration, stability control and torque distribution. The eight modes are - 'Sport', 'Off-Road Drift', 'All Purpose', 'Off-Road Auto', 'Off-Road Rock Crawl', 'Off-Road Rally', 'Conserve' and 'Towing'.

The ability to change torque distribution is the key function, as it allows for a wide variety of driving characteristics. For example, in Sport and Off-Road Drift it can send the majority of the power to just the rear wheels, allowing the R1T to perform like a rear-wheel drive vehicle. While in the Conserve setting it can send power only to the front motors to save energy. Or in the Rock Crawl setting it can send power to individual motors to help climb over obstacles.

The Sorento GT-Line PHEV offers a WLTP-rated electric-only driving range of up to 57km - not huge, but enough to cover most daily commutes or school runs without dipping into the petrol tank.

When driven as intended and regularly charged, it’s capable of a combined fuel consumption figure as low as 1.6L/100km and this is paired with a 67-litre fuel tank. That means you could go a seriously long time between fill-ups if you’re topping up the battery daily.

In my week of testing, which included a mix of highway stints and urban errands, the trip computer reported an average of 7.2L/100km.

That’s well above the official figure, but still pretty reasonable considering the type of driving I was doing.

Charging is simple enough. The Sorento uses a Type 2 charging port, and on a standard 3.3kW AC charger, the 14kWh battery can be charged from 15 to 95 per cent in about three hours and 26 minutes.

Kia includes a portable AC charger with this grade, which is a handy bonus for charging at home or on the go.

The range of the R1T depends on how much you're willing to spend. The standard battery provides 435km for the Dual-Motor AWD but if you pay for the Large battery that extends to 560km while the Max battery buys you a range up to 640km.

The Performance Dual-Motor comes standard with the Large battery, so it has a range of 560km with the option of 640km with the Max battery.

The Quad-Motor comes equipped with the Large battery as standard and has a 530km range, but it isn't available with the Max battery.

Rivian claims the R1T has a 220kW max charging rate on a DC fast charger. The company is rolling out its own network of charging stations in the US but crucially it also recently signed a deal with Tesla. 

A new 'Magic adapter' is now available so Rivian owners can access Tesla's network of more than 12,000 chargers in the US. Hopefully that deal carries across to the Australian market when Rivian arrives here.

The Sorento PHEV hits most of the right notes when it comes to power delivery and gear shifts. Occasionally, there's a slight hesitation between whether the engine or electric motor should take the lead - like a dance partner who’s just a touch out of step. It’s noticeable, but not disruptive.

Most of the time, the transition between power sources is smooth, and there’s more than enough grunt for overtaking or merging confidently.

The suspension has a springy, soft edge to it and you’ll feel some movement over bumps but it’s never harsh or uncomfortable. It corners surprisingly well for a large SUV, with responsive, albeit lighter, steering. Body roll is present if you push into tight bends, but that's par for the course in a seven-seater.

Regenerative braking is subtle, almost too subtle. There’s not much feedback, and it can feel a bit heavy underfoot in stop-start traffic. It’s not a deal-breaker, but worth noting if you’re expecting the more pronounced regen feel you get in some other hybrids or EVs.

The cabin remains quiet at both urban and highway speeds, making it easy to hold a conversation across all three rows. Visibility is generally good, though the thicker pillars take a little getting used to. The digital rearview mirror is a great touch when the back seats are loaded with people or gear.

Parking is refreshingly simple thanks to a crisp 360-degree camera and front and rear sensors. One of my favourite features is the remote smart parking, which lets you move the car forwards or backwards via the keyfob, a lifesaver in tight parking spots. Just don’t teach your eight-year-old how to use it ...

Like all EVs the R1T manages to combine rapid performance with a whisper-quiet powertrain, but what stands out is how refined the Rivian feels. For a car company's first effort the level of isolation you feel from the outside world is impressive. It doesn't have any of the squeaks, rattles and mechanical groans that plagued some other start-up EV car companies in their early days.

Instead, the R1T feels like a very complete and well resolved package. Like many modern EVs, starting it up is as simple as climbing into the driver's seat, with a sensor immediately preparing the car for you to head on your way without needing to press a 'start/stop' button.

Tap the gear selector stalk down for 'Drive' and you immediately experience the immense torque from Rivian's quad-motor powertrain. Even at suburban speeds you get a sense of the power that lurks beneath the surface of this ute.

Once we found a safe spot to unleash the full potential of the four motors they did not disappoint. It has the kind of sickening acceleration that we've come to expect from electric vehicles, with Rivian's 0-60mph (0-96km/h) claim of just 3.0 seconds feeling completely legitimate.

The regenerative braking is extremely powerful, and that's a pro and a con. That's because there are only two modes - standard and strong - but even in the lower setting there's powerful retardation as soon as you release the accelerator. This is very much an EV that can be driven on one pedal, which is fine, but it does take some getting used to.

A number of carmakers have begun offering much lower levels of regen braking, which allow you to drive more like a conventional internal combustion engine vehicle by using both the accelerator and the brake pedal, so perhaps a lower setting is something Rivian will have to consider in the future.

It also doesn't help that adjusting the regen braking is another function that requires you to dive back into the touchscreen menu, rather than using steering wheel-mounted paddles like other EVs have adopted.

The ride felt quite firm on the streets of Los Angeles, but that's not entirely surprising for what is a very heavy vehicle (it tips that scales at just over 3250kg) that's riding on 21-inch alloy wheels. However, given air suspension is standard across the range, it feels like it could be tweaked to make for a more compliant ride, especially on Australia's choppy roads.

The standard air suspension also allows for a variety of ride heights for improved off-road performance, with R1T able to adapt from as low as 241mm in 'Sport' mode all the way up to 378mm in its 'rock crawl' setting.

The R1T comes fitted with the usual array of airbags and passive safety systems, but Rivian founder Scaringe spent years working on autonomous vehicles as he built up his company so there's an array of active safety features that make the ute semi-autonomous.

Rivian calls this system 'Driver+' and it features all the now-normal active safety items like autonomous emergency braking, adaptive cruise control, lane change assist, lane keeping assist and blind-spot warning. The combination of these systems allows for some mild autonomous functions under the right circumstances.

Another interesting safety feature is called the 'Gear Guard' system. It's a complex system that includes a camera array, an external warning system and a physical cable in the tray.

Rivian calls it a 'family' of technologies but in simple terms it uses five of the pick-up's 11 cameras to monitor the surrounding area and sound an alarm if people are getting too close. If it sets off the alarm, the car will also send you a text message alert so you can check what's happening.

It also includes the Gear Guard cable, which is a braided steel cable with a nylon cover that you can thread through anything - such as a bike or other sporting equipment - and then lock into a connection built into the tray. Again, it uses the cameras to record anyone getting too close so you know who's tried to pinch your stuff.

The system also includes a cute monster mascot that pops up on the media screen to let people know they are being recorded. Plus it gives Rivian something to put on t-shirts to sell on their website.

The Sorento is backed by Kia’s seven-year/unlimited-kilometre warranty, which keeps the Sorento competitive in a market that is slowly starting to offer seven/year plus terms as standard.

You’ll also benefit from capped-price servicing for up to seven years or 70,000km, with an average cost of $764 per visit. That’s on the pricier side, especially when compared to some rivals.

Service intervals are every 12 months or 10,000km, whichever comes first, so if you’re someone who racks up the kilometres quickly, that could mean more frequent trips to the service centre than you’d like.

It’s also worth noting that the GT-Line PHEV requires a minimum of 95 RON premium unleaded petrol, which is something to factor into your ongoing running costs, particularly if you're already trying to offset fuel usage with regular charging.

In the US Rivian offers a five-year/60,000-mile (approx. 96,000km) warranty for the quad-motor models and a four-year/50,000-mile (approx. 80,000km) warranty for the rest of the range. But the battery and drivetrains are covered for up to eight years.
