Rivian R1S vs Chevrolet Silverado

What's the difference?

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.

This is a serious truck with load-carrying and towing capabilities far beyond Australia’s ubiquitous Ranger/HiLux-sized one-tonne utes. However, those vehicles thrive in urban use due to their relatively compact dimensions so, in that context, this pick-up is simply too large to be a practical alternative. However, if you have more specialised work and recreational requirements, like GCMs as high as 12 tonnes with spacious comfort for a crew of five, this big American would be tough to top.

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.

MY24 brings a freshened front-end appearance with new fascia, headlights, body-coloured bumpers and grille garnish, black body highlights and more.

With a traditional ladder-frame truck chassis and sprawling 4036mm wheelbase, this behemoth measures almost 6.4 metres in length (6387mm) and more than 2.2 metres in width (2263mm).

It also stands more than 2.0 metres tall (2039mm) and has a vast 16.1-metre turning circle. So, multi-storey car parks, drive-thru takeaways etc are best avoided. And domestic driveways (if wide and long enough to accommodate it) may suffer under its weight over time.

It rides on 20-inch high-gloss black alloys with LT275/65 R20 Goodyear Wrangler all-terrain tyres and carries a full-size spare.

New Z71 off-road suspension includes skid plates and Rancho twin-tube dampers, offering 251mm of ground clearance and 28.5 degrees approach/19 degrees ramp breakover/23.6 degrees departure angles.

However, its 4x4 capabilities would be better suited to accessing rugged worksites, pulling a large caravan out of a boggy campground or towing a large boat trailer up a slimy boat ramp, than hardcore bush-bashing on narrow tracks.

The Silverado’s extensive remanufacturing to RHD, performed on a dedicated production line in Melbourne, exudes OEM standards of fit and finish. The dashboard module is particularly impressive, in providing a mirror image of the LHD original in appearance and function.

The leather-appointed cabin is a highlight, offering palatial space and comfort for all. It features a tasteful blend of contrasting materials and surface treatments, including silver-grey woodgrain inserts on the doors, dash and centre console plus exposed stitching along seams and subtle splashes of chrome.

The entry pathway to the rear seat is expansive, thanks to wide-opening doors and a flat floor with no transmission hump to straddle. There’s executive-lounge rear head and legroom, even for tall people, combined with enough shoulder room to ensure a crew of five can travel in comfort.

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.

With its towering 3762kg kerb weight, the 2500 HD offers a choice of ADR load ratings (NB1 or NB2) which must be specified by the customer at the time of ordering (at no extra cost) to ensure the correct certification for vehicle registration.

The NB1 category allows up to 4500kg GVM/733kg payload, which can be driven by car licence holders. NB2 allows up to 5148kg GVM/1386kg of payload, but requires a truck licence. Our test vehicle is certified for the lower NB1 rating.

The 2500 HD is rated to tow up to 3500kg of braked trailer with a 50mm ball and up to 4500kg with a 70mm ball. These trailer weights are well within its capabilities, given that its GCM rating (how much it can legally carry and tow at the same time) is an eye-popping 12474kg.

Yep, that’s more than 12 tonnes, which allows for trailers weighing more than 4500kg using heavy-duty connections like pintle hooks, goosenecks/fifth-wheel turntables installed and certified by specialist aftermarket suppliers.

The enormous load tub offers almost 2.0 cubic metres of cargo volume and has large external steps front and rear for easier access. The load floor is 2089mm long, 1814mm wide and 533mm deep, with 1317mm between the rear wheel-housings allowing Aussie or Euro pallets to be carried.

It’s protected by a tough spray-on liner, plus there are 12 load-anchorage points, LED lighting, power tailgate and a camera to keep an eye on loads when driving. Our test vehicle was also fitted with adjustable and removable load-dividers, which are part of the GMSV accessories range.

Cabin storage for driver and front passenger includes two bottle/cupholders and a large bin in each door plus a single glove box. The centre console has a large open tray up front, two bottle/cupholders in the centre and an Esky-sized box at the back with padded lid that doubles as a plush elbow rest.

Rear seat passengers get a bottle/cupholder and bin in each door plus two more bottle/cupholders in the rear of the centre console and another two in the fold-down centre armrest. There are also large storage pockets on both front seat backrests and compartments cleverly hidden behind hinged upper backrest cushions.

The 60/40 split rear seat base can swing up and be stored vertically if more internal load space is required. This also provides access to the under-seat storage accessory fitted to our test vehicle. You’d seriously struggle to run out of cabin storage!

Our test vehicle is available only with GM’s 6.6-litre 'Duramax' turbo-diesel V8, 10-speed automatic transmission and dual-range 4x4 system for a list price of $163,000.

Our example has optional 'Slate Grey' prestige paint ($1250) plus GMSV accessories including a powered roller tonneau cover ($3970) and rear under-seat storage ($455) which adds more than $5600 to the price. So, with on-road costs, it's drive-away is more than $170K.

MY24 upgrades include styling, performance, towing and safety enhancements. There’s also a redesigned interior, with its most notable feature being upsized dash screens comprising a 12.3-inch configurable driver’s info display (paired with a colour head-up display) and larger 13.4-inch multimedia touchscreen. 

There’s also a premium Bose sound system, Apple/Android connectivity and wireless phone-charging, plus USB ports front and rear, dual-zone climate control, heated leather-rimmed steering wheel (with four-way adjustment), a power sunroof and power sliding rear window.

Leather-appointed seating offers 10-way driver and front passenger power adjustment, heated/ventilated front seats, heated rear seats, rear privacy glass, a power tailgate, tubular side-steps, 360-degree camera (and up to 14 different camera views), full LED lighting including fog lamps and DRLs plus heaps more. It’s what you might call fully-loaded - even without a load.

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.

The 6.6-litre Duramax turbo-diesel V8, with driver-switchable exhaust brake, is tailored for heavy-hauling with an external engine oil cooler and functional bonnet scoop feeding fresh air to the engine’s intake system.

In the latest MY24 specification, it produces 350kW at 2800rpm and 1322Nm of torque at 1600rpm. That’s 18kW and 98Nm more than the previous model.

The refined 10-speed torque converter automatic with column-shifter is also fitted with an external oil cooler, while closer gear ratios and revised final-drive ratios for MY24 enhance all-round performance.

A dual-range transfer case offers a choice of four drive modes comprising 2WD, 4WD high-range, 4WD low-range and Auto (traction-sensing full-time 4WD). Also new is an automatic-locking rear differential.

Its armoury of advanced towing hardware and technology includes a 4500kg tow-bar with 12-pin wiring harness and integrated trailer brake controller.

Plus, there’s a rear-view camera with hitch guidance, automated trailer lighting test, in-vehicle trailering app with trailer profiles, trailer theft alert, trailer tyre pressure/temperature monitoring and lots more.

New MY24 features include adaptive cruise control which can be used when towing (detecting the additional weight behind the vehicle to automatically increase braking distances). Others are 'Trailer Side Blind Zone Alert' (TSBZA), which extends the blind zone area when towing, plus 'Gross Combination Mass Alert' (GCMA) which alerts if you exceed the GCM.

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. 

The dash readout was claiming 17.5L/100km at the end of our 351km test, which comprised mostly city and suburban driving plus some highway running with a full payload.

Our own figure, calculated from fuel bowser and tripmeter readings, came in slightly lower at 16.8, which is decent economy for a vehicle weighing more than 3.7 tonnes unladen in ‘real world’ driving.

So, based on our figures, you could expect a realistic driving range of around 800km from its big 136-litre tank.

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.

Side-steps and large handles on the A- (and B-) pillars assist climbing aboard. It’s a very comfortable driving position, given the multiple seat and steering wheel adjustments along with plush elbow rests on both sides.

The large door mirrors, combined with numerous camera angles including the central rear view mirror's pin-sharp image, provide commanding all-around vision.

The steering is nicely weighted and surprisingly communicative for such a giant, providing good feel and response at all speeds.

The suspension tuning is supple enough to provide a smooth ride, yet retains enough firmness to minimise the ponderous feel inherent in vehicles of this size and weight.

Braking response is also reassuringly strong, without requiring huge pressure on the brake pedal to achieve it.

The 6.6-litre turbo-diesel V8 and 10-speed auto provide effortless performance. With maximum torque tapped at just 1600rpm, the engine is barely ticking over at city and suburban speeds.

And it requires less than 1500rpm to quietly maintain 110km/h on the highway, which combined with its low tyre and wind noise results in a supremely relaxed long-haul cruiser.

With its NB1 GVM rating, we loaded more than half a tonne into the load tub, which combined with our crew of two was just under its 733kg payload limit.

It simply didn’t notice the added weight, storming up our 13 per cent gradient, 2.0km-long set climb with acceleration unmatched by any loaded vehicle we’ve tested on this ascent.

Its engine-braking on the way down using the exhaust brake also set a new benchmark, never exceeding 50km/h and 2000rpm on overrun without once touching the brake pedal.

ANCAP star ratings are not applicable in this vehicle class, but it does come well equipped with six airbags including side-curtain protection for all outboard seating positions.

There’s also forward collision alert with low-speed AEB, lane departure warning, blind-spot monitoring (including when towing trailers), rear cross-traffic alert, front and rear parking assist, up to 14 camera views including 360 degrees ‘birds-eye’ and more.

There are three top tether points across the second row seat for securing baby capsules/child seats with ISOFIX anchors on the two outer positions.

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.

The Silverado is covered by a three year/100,000km warranty with three years roadside assist.

Scheduled servicing is every 12 months/12,000km, whichever occurs first, and there's no capped-price servicing. This ownership package falls short compared to rivals like Ford's RHD F-150.
