Kia Optima vs Rivian R1T

What's the difference?

If you travel long distances, want a good amount of space and don’t want to pay big bucks for a new car, then yeah, maybe there is a reason sedans like this will hang around for a while longer.

Sure, the appeal of sedans mightn’t be as strong as it once was, but models like the Kia Optima prove they still have a reason to exist.

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.

Cosmetic changes for the facelifted 2018 Kia Optima include new headlights and tail-lights with revised LED signatures (but still halogen lamps in the base model), and there are newly sculpted bumpers and new wheel designs across the two-model range. 

We had the base model Si, which doesn’t look as good as the GT model, because it has smaller wheels, the sporty body kit and misses out on the LED headlights, but the LED daytime running lights are still present.

The GT has a more aggressive look, and the side skirts, front spoiler and rear diffuser fit it better - there are dual exhausts, but not sporty quad exhaust tips.

In fact, this model is a bit like the old-man version of the Optima. No offence intended to old men, of course. The GT is just heaps sportier, and I reckon it’s considerably more attractive as a result. 

Still, the inherent sleek styling of the Optima remains - the chrome highlighting along the window line is a bit too sheeny for me, but the angles and stance of this model are quite gracious. I really dig the fact the top of the windscreen mirrors the ‘Tiger Nose’ grille shape.

I'm no exterior designer, but I liked the existing Optima more - it just looked a bit neater, even though it had a decent amount of bling with its Mercedes-like diamond-pattern grille, as opposed to the cheese grater look seen here.

There’s not quite as much bling inside the cabin of the Si, either, but it is still a well-designed space - just not as special as the premium package offering of the GT (which gets leather trim - not nappa leather, but still a quality cowhide finish, and more). Check out our interior photos to see if you agree - but size and interior dimensions of the Optima are hard to argue against.

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.

I really like the way Kia designs its cabins. Sure, there’s a lot of black in here, but there’s also a lot of thought put into the usability of the space.  

The high-mounted 7.0-inch infotainment and multimedia touch screen in the Si is simple to use, and for 2018 the Optima range gets Apple CarPlay and Android Auto - you couldn’t get that in the Optima up to this point. 

Also included are a reversing camera, USB input, Bluetooth phone and audio streaming and six speakers. The Si model misses out on sat nav - you’ll have to use the maps app on your phone. No DVD player either.

Storage is well thought out in here, with big bottle holders in the doors, a good sized pair of cup holders up front, and a nice little storage bin for your phone, wallet, keys and so on.

There’s a driver info screen with a digital speedo, and even on this base model you get a dual-zone climate control air conditioner. The updated Optima gets a new steering wheel, too.

Now, what about the back seat?

It may be considered a ‘mid-sized’ sedan, but there’s limo-like space. With the driver’s seat in my position (I’m about six feet tall) there was still heaps of rear legroom in the rear seat, with ample knee room, good foot room and decent shoulder space, too - three of me could slot across the back bench comfortably, which means kids will fit easily, too. There are three top-tether points and two ISOFIX points as well.

Kids and adults alike will be happy with the rear air vents back here, and there’s a flip down armrest with cupholders, too. Again, big bottle holders appear in the doors, and there are map pockets in the back seats.

What about boot space? With so many people choosing SUVs over sedans because they’re theoretically more practical, the Optima offers good food for thought - it has enough luggage capacity for a bunch of suitcases (510 litres VDA in size) and there’s a full-size alloy spare under the boot floor. If you need more, you could always invest in a roof rack setup?

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.

The Si model is powered by a 2.4-litre four-cylinder petrol engine, which has seen no changes to its specifications for this mid-life update.

Engine specs remain at 138kW of power at 6000rpm, while torque is rated at 241Nm at 4000rpm. It makes use of a six-speed automatic transmission only - there’s no manual transmission here, but you do get paddle shifters - and it's front wheel drive (the Optima isn't available with AWD, or as a 4x4, or in rear wheel drive - the latter is left to its bigger brother, the Stinger).

The GT gets a zestier drivetrain with more horsepower - it has a 2.0-litre turbo four-cylinder engine with 180kW/350Nm, which is much more desirable, but also louder than the Si’s 2.4. It also has a six-speed auto transmission, and is FWD. If you're into ratings and statistics, that 2.0-litre with a turbocharger is one of the perkier offerings for its engine size in the class.

There is no hybrid model available, despite a plug in hybrid petrol version (allowing you to run in EV mode) being sold in European markets. No diesel here, either, while other markets get a 1.7-litre turbo diesel. No LPG model here, or anywhere else, for that matter.

Towing capacity for Optima models is 750kg unbraked and 1700kg braked for the 2.4-litre, and 700kg/1400kg for the 2.0-litre turbo. Tow bar down-weight is capped at 80kg.

If you're concerned about engine problems, suspension problems, clutch and transmission issues, be sure to check out our Kia Optima problems page.

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.

Kia claims a very realistic fuel economy rating of 8.3 litres per 100 kilometres for the Si model, and we saw damn close to that consumption during our week of testing. On the highway it will sit at around 6.5L/100km, ensuring good mileage, while city driving will push usage above 12.0L/100km. Our overall average was 8.5L/100km, which is good. Use the eco mode, and you'll get a little better use.

The turbocharged GT model uses a little more, according to Kia’s 8.5L/100km combined average claim, but we guarantee you’ll actually use more than that because it’s more eager to please.

Fuel tank capacity is 70 litres - plenty of size for long distance drives.

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 Optima has some really good elements to the way it drives, but sadly  some less impressive bits as well.

Let’s start with the not-so-great stuff - the 2.4-litre engine in this Si model just isn’t as enjoyable as the turbo unit, and the fact that Kia still doesn’t offer a hybrid version here, despite doing so elsewhere, is a bit of a downer.

The drivetrain isn’t terrible - the six-speed auto is smart enough, and there’s usable power if you boot it. The two more sedate drive modes, 'Eco' and 'Comfort', mean the transmission will aim to save fuel and limit throttle response, with a bit more of a lazy feel to the drive experience. But in 'Sport' mode it is definitely more rewarding in terms of acceleration and performance, offering a bit more pep and urgency (we didn't do a 0-100 km/h speed test, but take our word for it); it undoubtedly at the cost of fuel consumption.

It’s just a bit of a shame Kia doesn’t offer the turbo in this spec, too. Fuel use for the Si model is better than the turbo, however, so it could be ideal for buyers who are more worried about the bottom line than design and a sportier drive.

The thing I like most about the Optima is its road manners - the steering and suspension have been tuned for local conditions, just like all Kia products, and it shows. 

The electric power steering is really well sorted, making for easy parking moves and good assuredness at higher speeds. And the turning circle is decent, too - 10.9m (so, the turning radius is 5.45m). 

Plus the ride comfort is really good. On the highway it coasts along with very little fuss, and around town it deals with lumps and bumps impressively. Sharp edges can upset things a tad, and mid-corner bumps can make it jitterbug a little bit, but not to a degree that would rule it out of contention if you want a mid-sized sedan.

It’s pretty quiet on the open road, too, and the adaptive cruise control makes long-distance driving a simple task. The GT does suffer a little bit more road noise, though.

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.

Kia remains a shining light in terms of its new-car-ownership promise, with a very strong seven-year/unlimited kilometre warranty. It makes a lot of sense if you plan to hang onto the car for a while. There's no extended warranty available, which is understandable.

That plan also includes a roadside-assist plan for the same seven-year period, provided you maintain your car with Kia Australia. So, given you get one year to start with, then you get an extra year of cover every time you go back to Kia to get your car serviced, you could end up with eight years of coverage. Nice!

Servicing is due every 12 months or 15,000km, with the first seven years covered by a capped-price-service cost / maintenance cost plan. The costs are: service one - $289; two - $466; three - $360; four - $559; five - $325; six - $599; seven - $345. That makes a total cost of $2943, which is competitive for its class. Keep your owners manual or logbook up to date, and your resale value should hold up better.

If you have concerns about common problems, issues, reliability ratings and durability, you should check out our Kia Optima problems page.

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.
