Kia Stinger vs Rivian R1S

What's the difference?

The Stinger GT-Line is a great machine. It looks good, feels good to drive and while it's not the cheapest large sedan, it's also not a Camry. With a strong European vibe, it's a nice bridge between boring-dependable and out-of-reach European. Boasting a strong link to Europe in its chassis DNA, it has it all apart, maybe, from the badge.

But Kia has a habit of doing unexpected things and the Stinger was a bold move worth making just for the halo effect of having such a cool car in the range. It has done good things for the company's reputation, as though the rest of the range isn't proof already.

While there are some obvious signs that the R1S is Rivian’s first mass-market vehicle, the good news for the company is that its problems are not impossible to overcome. The suspension needs retuning to improve the ride quality and the multimedia system’s software needs upgrading. But even with those issues the R1S left a positive impression.

This is a very stylish SUV with great space and excellent performance, that also happens to be electric, rather than relying on being electric as its primary selling point.

Rivian has put more effort into the design and finishes than many of its EV rivals and the result is a vehicle that can genuinely compete with the established premium players with more credibility.

The only catch is there’s no clear timeframe for when, or even if, this generation of R1S will make it to Australia. The brand has repeatedly spoken of its hopes of entering the market here without locking anything in, but given the current state of the EV sales it may pay off to wait until the conditions are right for a new, premium player to try its luck here.

The Stinger looks fantastic. I know the car has its detractors, but there's a massive Euro influence here that sits well in my visual cortex. It's maybe not as ooh-aah as the A5 or the outgoing BMW 4 Series Gran Coupe, but the Stinger can and should be mentioned in the same breath. It looks terrific, even if it is a bit fussier in the details.

From the signature grille, the low beltline, big wheels and sports coupe roofline, it looks sleek and sophisticated. 

Inside is a bit more conventional, with some real classic touches such as circular air vents, conventional-looking gear selector and a flat-bottomed steering wheel. It's cool, clean and, with the big new screen, a bit more techy-looking than before. There are lots of nice materials and the odd rogue one, but it's a good cabin that feels well put-together.

Design is another area where Rivian has carved out a unique position for itself. Whereas other brands, including Tesla, have focused on simplicity and aerodynamic efficiency, Rivian has given the R1T a unique style that looks interesting, different and most definitely not plain.

The oval daytime running lights make every R1S and R1T stand out from a mile away, even on LA’s busy freeways. The overall design is high quality and manages to strike a good balance between aesthetics, aerodynamics and practicality - even if it doesn’t suit everyone’s personal taste.

The cabin is worth highlighting in particular, because rather than go for the ‘minimalist’ look that so many brands are going for these days, with as little switchgear and different trims as possible to keep costs down, Rivian has opted for something more complex and, frankly, more impressive.

There’s a level of craftsmanship, a great mixture of premium materials (including some striking light wood options) that make the R1S feel like a stylish and relaxed environment inside the cabin. Our particular example had a great mixture of colours, textures and patterns that really elevated the cabin experience.

The technology is also nicely integrated into the design, rather than being the focal point, like so many other modern electric vehicles. It still offers the same level of technology - a pair of screens - but doesn’t rely on them to carry the design of the interior.

This is really a four-seater car. While there is good legroom in the rear, the falling roofline, small door aperture and huge transmission tunnel box you in a bit, almost rendering the middle seat useless for all but the shortest of folks. You do get your own air vents, though, which is generous.

The low roof also means limited headroom, made a little worse by the standard sunroof. I had room but taller people might brush the headlining. There are two cupholders front and rear for a total of four and each door has a bottle holder.

The boot is a modest-for-this-size 406 litres, rising to 1114 litres with the seats down. Access to the boot is good if not spectacular; the hatch opens wide but a slightly narrow aperture means loading and stowing flat packs and things like that could be a struggle.

The R1S comes standard as a seven-seat SUV, split across three rows (two in the first row, three in the second row and two in the third row). Space across the three rows is fairly typical for an SUV of this size, which is to say generous up front, good in the second row and a little bit tight in the back.

What is good though, is the length of the cabin allows for quite a spacious boot even with the third row in use, which is definitely not something all seven-seat SUVs can claim. Using a direct conversion from Rivian’s specifications that list cargo capacity in cubic feet, the R1S has a claimed 498 litres with the third row in use and up to 1331L with the third row folded down. There’s also 314L under the bonnet and another 144L underneath the boot floor (although that comes at the expense of a spare tyre).

As mentioned in design, Rivian has nicely integrated the technology into the cabin, with the 12.3-inch digital driver display and 15.6-inch central multimedia touchscreen feeling like a natural part of the car rather than a centrepiece. Rivian has also managed to incorporate eight USB-C charging ports spread around the cabin to keep everyone’s devices charged up.

However, while the technology is nice from an aesthetic design perspective, the same cannot be said about its useability. Like Tesla, Rivian has opted to go it alone with its multimedia system and has developed its own Google-based software that is not compatible with either Android Auto or Apple CarPlay. That would be acceptable, although still disappointing, if the system worked as well as Tesla’s, however the Rivian system is very slow. It repeatedly took several seconds to load between the various functions, which may not sound like long, but when you’re trying to get back to the navigation so you don’t miss your freeway exit a few seconds can make a big difference.

But, honestly, in this day-and-age, systems like this should work quickly and seamlessly, so it’s an area Rivian needs to improve.

On a positive note, Rivian does have some cool accessories for the R1S including what it calls a ‘Camp Speaker’ which is a US$400 option that it integrates into the sound system but is also removable, so you can pull it out of the centre console and listen to your music if you’re around the campfire or having a picnic.

When we drove the R1T in 2023 Rivian was still in the ramp up stage of production and was limited with what it could offer customers. Fast forward to 2025 and the brand now has both the R1T and R1S available with dual or tri motor powertrains, with a quad-motor powertrain expected by the end of the year.

The R1S Dual Standard begins the range at US$75,900 (approx. A$118,000), the R1S Dual steps it up to US$83,900 (A$130k) and the R1S Tri-motor completes the current line-up at US$105,900 (A$165k). While those prices are definitely in the premium end of the market the R1S is actually cheaper than the Tesla Model X, which is still on sale in the US market, and starts at US$86,630 (A$135k) and stretches to US$101,630 (A$158k).

For more context, the Audi Q8 e-tron starts at US$74,800, the BMW iX from US$87,250 and the Mercedes-Benz EQE from US$77,900.

Standard equipment across the range includes the 12.3-inch digital instrument display, 15.6-inch multimedia touchscreen, dual-zone climate control, heated and ventilated front seats, heated steering wheel, eight-way power adjustable driver and passenger seat and panoramic glass roof, so it certainly has premium levels of equipment.

We drove the range-topping RS1 Tri-motor which, aside from an extra motor, gets standard 22-inch alloy wheels, a dynamic glass roof, a soft-touch suede textile headliner as well as unique colour and trim options.

Under the GT-Line's bonnet is Kia's Theta II 2.0-litre four-cylinder turbocharged engine. It's the same as before, with a stout 182kW and 353Nm. Driving the rear wheels is an eight-speed automatic from the Hyundai-Kia empire.

It's pretty rapid, knocking out the 0-100km/h spring in just six seconds, a mere 1.1 seconds slower than its faster sibling's 4.9 for the benchmark.

As mentioned earlier, there are currently three versions of the R1S available, each with a different powertrain. 

The Dual Standard AWD has, unsurprisingly, dual motors (one at the front and one at the rear) which make a combined 397kW/827Nm. That’s enough for it to launch 0-60mph (0-96km/h) in just 4.5 seconds. The R1S Dual AWD has the same power, torque and acceleration figures, however it gets Rivian’s Large battery, which we’ll detail below.

The Tri-Motor AWD obviously has three motors, one on the front axle and two on the rear, which naturally provide more power, 633kW/1495Nm. With so much power and torque the Tri-motor is wickedly fast, taking just 2.9 seconds to launch 0-60mph.

If, for some reason, the Tri-Motor isn’t fast enough for you, Rivian has released the details on the Quad-Motor. It will have two motors on each axle providing a staggering 764kW (that’s 1025-horsepower!) and 1624Nm, enough to rocket it from 0-60mph in just 2.6 seconds and across the quarter mile in 10.5 seconds.

Kia's claimed combined cycle figure is 8.8L/100km. As the Stinger goes without trickery like stop-start or mild hybridness, it's no surprise that my week with it yielded an indicated 10.4L/100km, which isn't bad for a 1750kg sports sedan that was not molly-coddled and also spent some time in a resurgent case of crap traffic in Sydney.

It also drinks standard unleaded, which is a nice touch.

Rivian offers three different battery types across the three variants, each with a different driving range. The R1S with the Standard battery (92.5kWh) has a claimed 434km driving range, the R1S Dual with Large battery (109.4kWh) extends that to 530km, while the Tri-Motor comes standard with the Max battery (141.5kWh) that has an impressive 597km of range.

It is worth noting, though, that those range claims are based on US EPA estimates, rather than either the WLTP or NEDC methods usually used.

Charging times vary depending on the type of charger used, in the US Tesla has given access to its network to other EV brands and the Rivian is available with a plug adaptor to use a Tesla charger. The R1S is capable of charging up to 220kW, which means it takes approximately 40 minutes to take the battery from 10 to 80 per cent. 

I have driven and loved the Stinger GT. It's tremendous fun, goes like a rat running away from a cut snake, which itself is being chased by a mongoose with its bottom on fire, and it handles like a proper sports sedan.

The GT-Line is obviously not that quick, but it's not slow, either. But it does take a bit of the GT's DNA and delivers a driving experience eerily reminiscent of an E90 BMW 3 Series. That seems like an out-of-date reference, but it was a beautiful car to drive with a lovely balance of ride and handling.

The steering has good feel and you know what's going on underneath the front wheels. You sit towards the centre of the car, also a BMW trademark. Turn the wheel and the car goes with you, despite its bulk, and it's happy to dance a bit with its limited-slip diff.

The 2.0-litre turbo does a good job in most conditions but you feel it coming up short when you're hustling it. It's never breathless, but the torque deficit to the turbo six is clear. If you've not driven the faster Stinger, you may not notice, but there's a touch of lag in the 2.0 that contributes to the idea it's working hard to move the big sedan.

But back off a little and it becomes a fluid, fun drive. In town it's firm but very comfortable, gently bumping rather than crashing into potholes. The rear suspension is a complicated five-link set-up that costs money and eats into boot space but delivers the goods.

Given its length the Stinger is a bit tough to manoeuvre in tight spaces and its 11.2m turning circle isn't too flash either, but you soon get used to it.

The R1S and R1T are Rivian’s first mass-produced cars, and it shows. It’s not all bad news by any stretch, but there are some major issues the brand will need to address in the future if it wants to succeed globally (or even just in the US). 

The biggest issue is the ride, which just doesn’t feel as well resolved as the more established brands that have been designing, developing and building cars for decades. The R1S isn’t bad to drive by any stretch, but the ride is too firm at times and it also lacks control and feels too soft at others. 

All R1S grades come standard with Air Suspension that has multiple levels of firmness and can adjust the ride height. However, in the ‘normal’ setting the ride feels too busy, with the heavy (3096kg) SUV skittering over the imperfections in the road rather than absorbing them. The problem is, if you adjust the suspension to the softer setting it lacks control and has a tendency to bounce over bigger bumps and take a few seconds to settle. This was particularly noticeable on LA’s concrete freeways, but it would be an issue on any road with undulations or joints.

But while the ride needs improvement, the R1S has strengths in other areas - namely performance. The Tri-motor AWD we sampled had immense punch from its three motors and it certainly felt like 633kW and 1495Nm was on tap. We didn’t test its acceleration claim officially, but any take-off could be made into a rapid one with just a squeeze of the accelerator pedal. 

The R1S is also capable of towing up to 3500kg, so it’s a strong and capable SUV too, rather than just a speedy EV.

Another strength is the regenerative braking system. There are multiple settings but we found the lowest regen was the best option, as it still provides powerful regen but is more progressive than the more powerful modes.

The R1S comes loaded with safety equipment across the range, including eight airbags, adaptive cruise control, autonomous emergency braking, blind spot monitoring, forward collision warning, lane departure warning, lane keeping assist and rear cross-traffic alert.

It also comes with what’s called the ‘Rivian Autonomy Platform’ that includes 11 cameras and 12 ultrasonic sensors for mild-autonomous functionality in specific circumstances, such as freeway driving or on well-marked roads. 

Kia's ground-breaking seven year/unlimited kilometre warranty along with roadside assist for the first 12 months. Each time you service your car at Kia, you get an extension on your roadside assist for up to eight years.

Perhaps the only thing that makes you go, "Oh, what?" about the Stinger is the 12 months (Good)/10,000km (Oh...) service intervals. That's pretty common with Kia's turbo engines but is a little inconvenient. Then there's the cost - prices range from $312 to $685, which adds up to $3459 over the first seven services. If you stay under 10,000km/year, that's not bad going at under $500 per year for servicing, but if you're a high-miler, it will add up.

The servicing isn't outrageous - and the prices are capped - but it's not cheap, either.

Rivian offers a four-year/80,000km warranty for the R1S vehicle as a whole, as well as a separate battery pack and drivetrain specifically. The Standard battery is covered for eight years/190,000km while the Large and Max batteries are covered for eight years/240,000km.

As for servicing, Rivian uses an app-based system, which allows owners to schedule a service at any time via the app and then either have a Rivian technician come to your home for a small service or drop it off at a service centre if it’s a bigger job. The app is also connected to the car, so if the car’s own diagnostic system recognises a problem, it can prompt you to book a service proactively.
